What is a no-drill window air conditioner?
A no-drill window air conditioner is an all-in-one cooling unit that mounts into a compatible window opening using clamp-style brackets and sealing panels — with no wall drilling, no façade modification and no separate outdoor condenser. Because installation is reversible, it suits renters, apartments and historic European buildings where permanent AC installation is restricted. Most users complete a first-time self-installation in well under an hour with basic hand tools, subject to window compatibility, lease terms and local building rules.

Where Is This Window AC Best Used?
Rental apartments
The headline use case: reversible mounting protects deposits and sidesteps most permanent-installation objections. Take it to the next flat when the lease ends.
Studio flats & small living rooms
Zero floor footprint matters most where every square metre is furniture. The 9,000 BTU class matches typical 12–18 m² urban studios.
Bedrooms
Sleep mode, night-tuned acoustics and compressor placement at the window line make overnight cooling livable — the single most requested scenario in our European feedback.
Home offices
Steady inverter output keeps temperature stable through video calls; no hose across the floor, no tank to empty mid-meeting.
Historic-building applications
Suitable where a removable window installation is permitted: no façade penetration, no external condenser. Always confirm heritage and condominium requirements first — see our historic buildings guide.
Compatible window configurations
European vertical/casement and tilt-turn formats within the model's published opening range. Narrow openings: consider the Compact Series. Free fit check via WhatsApp.
Cooling a European Apartment Shouldn't Require Permission, Permits and a Six-Week Wait
European summers are getting hotter, longer and harder to sleep through — while the buildings Europeans live in were designed for a climate that no longer exists. When a heatwave arrives, the traditional cooling market fails apartment dwellers in four predictable ways:
Permanent drilling
Split systems need a hole through the external wall and a condenser bolted to the façade. In Haussmann-era Paris buildings, German Altbau flats and Italian historic centres, that is often restricted by the lease, the condominium, or heritage rules — sometimes all three.
Installation delays
Certified HVAC installers are scarce across Europe, and during a heatwave the queue explodes. People suffering at 30 °C indoors are quoted appointments weeks away. Heat is a today problem; split-AC installation is a next-month answer.
High labour cost
Professional installation frequently costs as much as — or more than — the appliance itself once wall work, refrigerant handling and scaffolding for upper floors are included. That doubles the real price of "affordable" cooling.
Rental restrictions
Tens of millions of Europeans rent. A tenant who drills the wall risks their deposit and a dispute; a tenant who buys a split system pays to improve a property they'll leave. Renters need cooling they can install without permission and take with them.
Our design thesis: the biggest barrier to cooling in Europe is not the price of the machine — it is the friction of installation. Remove the drilling, the outdoor unit and the installer, and you remove the barrier. That is the entire reason the Reveluz® no-drill platform exists.
Tell Us About Your Building — We'll Recommend a Model →Built Around the Way Europeans Actually Live
1 · No-Drill Installation
Clamp brackets grip the window frame; adjustable sealing panels close the remaining opening. Nothing penetrates the wall, nothing hangs on the façade. When you leave, the window returns to exactly how it was. Function → Scenario → Benefit: reversible mounting → restricted buildings and rentals → cooling without permission, penalties or repairs.
2 · True Self-Installation
Unpack → fit → secure → seal → plug in → cool. The kit ships with pre-assembled brackets, a printed EU-language quick guide, a QR-linked installation video and every required accessory in the box. Basic hand tools only. No refrigerant work — the circuit is factory-sealed and tested before packing.
3 · Renter-Friendly by Design
Removable, deposit-safe, and legally lighter-touch than permanent installation: because no-drill systems avoid wall penetration and a fixed outdoor unit, they may reduce many of the approval barriers renters face. Always check your lease, condominium rules and any local façade or heritage requirements — we say this on every page because honest answers build trust.
4 · Inverter Energy Efficiency
The inverter control system adjusts compressor output to actual cooling demand instead of hard on/off cycling. That means steadier room temperature, less start-up current draw, and lower energy use across long summer evenings — exactly what matters in high-electricity-price markets like Germany and Italy. Each model's class is stated on its EU energy label and verifiable in EPREL.
5 · Quiet Cooling for Bedrooms
Designed for night-time use: optimised fan blade geometry, compressor vibration isolation and a dedicated sleep mode that steps the setpoint and fan speed down as you fall asleep. Rated sound power is printed on the energy label of every model — we publish tested numbers, never adjectives alone.
6 · Engineered for European Windows & EU Rules
This is the difference we are proudest of. Reveluz units are designed for European window configurations — including tilt-turn and vertical formats — not simply re-boxed from US-market sash-window platforms. Electrically: 220–240 V / 50 Hz, EU plug. Regulatory: CE (LVD + EMC), RoHS, ErP Ecodesign, EU Energy Label, F-Gas documentation. The compliance file ships with the goods.
How to Install a Reveluz No-Drill Window AC
A realistic first-time installation takes most people under an hour. Here is the actual process — eight honest steps, not a fantasy "10-minute" claim:
Measure the window
Check opening width and height against the model's compatibility chart before you buy. We confirm fit on WhatsApp from a photo + two measurements.
Prepare the mount
Attach the clamp brackets and support rail to the frame per the illustrated guide. No drilling into masonry — ever.
Position the unit
Two people lift the unit onto the rail; the safety catch engages automatically. Verify the slight outward tilt for condensate flow.
Secure & level
Tighten the clamps, check the spirit-level indicator, confirm the unit cannot shift in the opening.
Seal the opening
Fit the adjustable side panels and foam sealing strips. Good sealing is the single biggest factor in real-world efficiency.
Check drainage
Confirm the condensate path per your model (slinger-ring or drain-port versions differ). The manual shows both.
Plug in
Standard 220–240 V EU socket. No dedicated circuit is required for this appliance class; no electrician visit.
Test & cool
Run cooling mode for 15 minutes, verify cold discharge air and quiet operation. Then close the curtains and enjoy the evening.
Every unit ships with a printed multilingual manual (EN/FR/DE/ES/IT), a QR-code installation video, and human support: send a photo of your window to WhatsApp +86 152 2110 6790 and an engineer — not a bot — replies with a fit assessment.

Inside the RVZ-W9i: The Anatomy of Reliable Cooling
A window AC is honest engineering: one sealed refrigeration circuit, two heat exchangers, one clever airflow path. Knowing what's inside is the fastest way to judge quality — so here is ours, opened up.
DC inverter compressor
The heart of the unit. Variable-speed operation matches output to demand — steadier temperature, softer starts within domestic circuit limits, lower seasonal consumption, and less mechanical stress, which is why we can discuss extended compressor warranty terms with B2B partners.
Twin heat exchangers
Copper-tube, aluminium-fin evaporator and condenser sized for European 220–240 V/50 Hz operation from day one — not derated from another market's platform. Fin coating specified for humid coastal deployments (Mediterranean and Atlantic markets).
Acoustic & airflow package
Cross-flow indoor fan geometry, compressor rubber isolation mounts and a discharge path tuned in our acoustics room. Rated sound power goes on the energy label; the engineering above is how it gets there.

We compare our own models against each other rather than publishing unverifiable claims about competitor brands — choose by your room, window and priorities, and message us if two models both seem right.
What Size Window AC Do You Need?
Direct answer: for most insulated European rooms, choose roughly 7,000 BTU for 8–12 m², 9,000 BTU for 12–18 m², and 12,000 BTU for 18–25 m². Then adjust for sun-facing façades, top-floor flats, high ceilings and poor insulation — each of these pushes you toward the next size up.
| Capacity | Suggested room size | Recommended use | Reveluz series |
|---|---|---|---|
| 7,000 BTU | 8–12 m² | Bedroom · small studio · student room | Basic / Compact |
| 9,000 BTU | 12–18 m² | Studio apartment · master bedroom · home office | Inverter / Ultra-Quiet |
| 12,000 BTU | 18–25 m² | Larger living space · open-plan studio | Smart WiFi |
Guideline values for typical insulation and 2.4–2.7 m ceilings. Final sizing should account for orientation, glazing, occupancy and local climate — a south-facing attic room in Seville is not a north-facing ground floor in Hamburg. For a personalised calculation, read our guide How to Choose the Right BTU or message your room dimensions to WhatsApp.
Window AC or Portable AC: Which Is Better for a European Apartment?
Direct answer: for fixed-room cooling in an apartment, a window AC is generally the stronger choice — it frees your floor space, avoids the single-hose exhaust problem, and keeps compressor noise at the window line rather than beside your bed. A portable AC wins only when you genuinely need to move the unit between rooms daily or no window in the home is compatible.
| Criterion | Reveluz No-Drill Window AC | Typical Single-Hose Portable AC |
|---|---|---|
| Cooling delivery | Sealed installation; heat rejected fully outside the room envelope | Hot exhaust hose radiates heat back into the room; hose-window gap leaks warm air in |
| Negative pressure effect | None — no air is pumped out of the room | Exhausted indoor air is replaced by warm air pulled in from outside/other rooms |
| Floor space | Zero — the unit lives in the window plane | Occupies floor area plus hose run in already-small European rooms |
| Noise location | Compressor sits at the window line, partially outside the room acoustic space | Entire machine, compressor included, stands inside the room |
| Installation | One-time no-drill mount; then just a plug | "No install" — but the window kit must be refitted and re-sealed constantly |
| Portability between homes | Fully removable; moves with you at end of tenancy | Also portable, at the cost of the drawbacks above every single day |
| Typical real-world efficiency | Higher for a fixed room, because the envelope stays sealed | Reduced by exhaust-heat leakage and infiltration (magnitude varies by room and product) |
We deliberately do not print a universal "X% more efficient" figure here: real-world differences depend on room sealing, hose length, climate and the specific portable model. Where we publish comparative numbers, they come from controlled testing and we can show you the test conditions. Full analysis with methodology: Window AC vs Portable AC — the complete guide.
Ask an Engineer Which Suits Your Room →Designed Around European Windows — Not Adapted From US Hardware
Most "window ACs" on the global market were engineered for the American vertical sash window. Europe barely uses that window. Selling US hardware into Europe and hoping the buyer improvises a frame is, in our view, the reason this category under-performed in Europe for decades. We took the opposite path: measure European windows first, design the chassis and mounting system second.
Window formats we engineer for
- Tilt-turn (Dreh-Kipp) — the dominant format in Germany, Austria and much of Central Europe; our sealing panel system works with the sash open in turn position.
- Vertical / casement openings — common across France, Spain and Italy; clamp-rail mounting adapts to frame depths typical of both PVC and timber joinery.
- Older single-glazed timber frames — found throughout historic districts; load is spread across the frame with protective liners so period joinery is not marked.
- Compact/narrow openings — the Compact Series chassis exists specifically for small studio windows the standard chassis cannot fit.
Each model publishes a compatible opening range (min–max width and height) in its datasheet. Unsure? Photo + tape measure + WhatsApp = answer within one working day.
European electrical standards, natively
- 220–240 V / 50 Hz design voltage — not a 115 V/60 Hz platform with a transformer bodge.
- EU plug types fitted at the factory per destination market (Schuko for DE/ES/others; Type E for FR; Type L available for IT; Type J for CH on request).
- Rated current within normal domestic circuit limits for this appliance class — plug in and run; no dedicated line, no electrician.
- Safety systems: over-current protection, compressor thermal protection, restart delay, and LVD-tested insulation throughout.
Country-by-Country: How Europeans Cool, and How We Fit In
Generic "Europe" marketing convinces nobody. Below is what we have actually learned shipping into each Tier-1 market — housing stock, habits, regulation flavour, and the local search language your customers use. Each summary links to a full localized country guide.
🇫🇷France — the no-drill heartland
Paris and other dense cities are dominated by pre-war apartment stock where façade drilling routinely requires copropriété (condominium) approval, and Haussmann façades may face heritage constraints. Meanwhile air-conditioning penetration in French homes remains far below hot-climate markets, so each heatwave triggers an emergency-purchase spike and installer gridlock. French buyers search climatiseur de fenêtre clim sans perçage climatiseur fenêtre appartement clim fenêtre silencieux. Local realities we accommodate: Type E plugs, narrow openings behind traditional shutters (persiennes), and strong sensitivity to night-time noise in courtyard buildings. → Guide complet en français · Clim sans perçage
🇩🇪Germany — efficiency and rules first
German buyers read the energy label before the price tag. High electricity prices make inverter efficiency the deciding argument; tenant law (Mietrecht) and building alteration rules make "no permanent modification" the qualifying argument; and Denkmalschutz (heritage protection) can restrict façades in older districts. Tilt-turn windows dominate — precisely the format our sealing system was engineered around. German search language: Fensterklimaanlage Klimaanlage ohne Bohren leise Klimaanlage Schlafzimmer. Documentation culture matters: we supply the DoC, energy label and technical file proactively, in German. → Ratgeber auf Deutsch
🇪🇸Spain — long seasons, running-cost focus
Spain's cooling season is long and intense, AC is culturally normal — but installation queues in June–July are brutal, and rental apartments in Madrid, Barcelona and coastal cities face the same drilling restrictions as elsewhere. Spanish buyers are acutely running-cost aware after recent electricity price volatility; siesta-hour and night-time noise courtesy norms (and community ordenanzas on noise) make the Ultra-Quiet series relevant. Search language: aire acondicionado de ventana aire acondicionado sin instalación aire acondicionado bajo consumo. → Guía en español
🇮🇹Italy — historic centres, condominio rules
Italian historic centres are the world's densest concentration of "you cannot touch that façade." Centro storico regulations and condominio assemblies make external condensers a negotiation, not a purchase. Italians also live with some of Europe's tightest domestic power contracts, which rewards inverter soft-start behaviour and modest rated current. Search language: condizionatore da finestra climatizzatore senza installazione fissa condizionatore silenzioso camera da letto. Type L plug versions available from the factory. → Guida in italiano
Legal framing note — we choose our words carefully: no-drill systems avoid permanent wall penetration and a conventional outdoor-unit installation, so they may reduce many common approval barriers. They are not a blanket exemption from every rule everywhere. Check your lease terms, condominium/copropriété rules, façade and heritage restrictions, and local requirements. Any supplier who tells you "fully allowed everywhere, guaranteed" is telling you what you want to hear, not the truth.
Built for the European Market — and Documented Like It
Compliance is not a logo on a carton for us; it is a file of documents you can hold, check and audit. Every Reveluz model destined for the EU ships with a complete, verifiable compliance pack. Here is exactly what that covers:
CE Conformity
Electrical safety (Low Voltage Directive) and electromagnetic compatibility (EMC Directive) testing at accredited laboratories, RoHS material compliance, and a signed Declaration of Conformity naming the exact model. We give distributors the DoC and test report numbers so they can verify — we don't ask anyone to take our word for it.
ErP Ecodesign & EU Energy Label
Models are tested to the applicable Ecodesign requirements and carry the EU Energy Label with seasonal efficiency, annual indicative consumption and sound power. EU-market listings are registered in the public EPREL database — meaning you, or your trading-standards authority, can independently confirm our figures. Higher efficiency is not just a badge: it is lower operating cost through every long heat period.
F-Gas & Refrigerant Documentation
Refrigerant type, charge and GWP are stated on the rating plate and in the technical file, in line with the EU F-Gas framework. Circuits are factory-sealed, leak-tested before packing, and classified for the installation type — the end user never handles refrigerant. Import paperwork (including refrigerant declarations customs may request) is prepared by us, not left for you to figure out.
The document pack every partner receives
| Document | Purpose | When you get it |
|---|---|---|
| CE Declaration of Conformity | Legal conformity statement per model | With quotation on request; final signed copy with shipment |
| LVD / EMC / RoHS test reports | Independent lab evidence behind the DoC | Under NDA at sampling stage |

Reveluz®: A Shanghai Cooling Specialist, Exporting Since 2010
Reveluz® has developed and supplied air-conditioning products from Shanghai since 2010 — fifteen-plus years of design iterations, export seasons, EU documentation cycles and, frankly, mistakes we made early and fixed permanently. This page was written by the same team that answers your WhatsApp messages: product engineers who have measured European window frames by hand, and export managers who have walked containers through Rotterdam, Hamburg, Le Havre, Barcelona and Genoa customs.
Experience: product decisions on this platform trace to field findings — sealing kits redesigned after French shutter clearances proved tighter than drawings suggested; bracket liners added after a German partner showed us marked timber frames; sleep-mode logic re-tuned after real bedroom feedback, not lab assumptions.
Expertise: in-house refrigeration engineers, an acoustics test room, and a compliance team that lives inside LVD, EMC, ErP and F-Gas paperwork all year — not only when an order lands.
Authoritativeness: we publish datasheets, energy labels and compatibility charts openly; our guides are cited and linked by partners because the numbers in them can be checked.
Trustworthiness: a real registered address, a landline, a fax (yes, some European purchasing departments still ask), verifiable certificates, and a standing invitation: video-audit our factory floor on a live call before you pay anything.
An engineer's honest take
"Buyers ask me: why did window ACs never take off in Europe when they dominate elsewhere? My answer after fifteen years: the product was never the problem — the fit was. US-format machines meeting European windows was a bad blind date, repeated for decades. The moment you engineer the chassis, mounting and sealing around tilt-turn and casement windows, add an inverter for European electricity prices, and hand the customer a genuinely one-hour reversible install, the category suddenly makes sense here. That re-engineering — not a cheaper price — is the whole opportunity. And one warning I give every new distributor: never let anyone, including us, sell you performance numbers without a test report behind them. In this business, the datasheet is the handshake."
— Senior Product Engineer, Reveluz® window AC platform team, Shanghai
Talk Directly to Our Engineers →Seven Checkpoints Between Raw Material and Your Container
"100% tested" is a claim; a checkpoint list is a process. Here is ours — and any partner may witness it live on a video call or through a third-party inspector at any checkpoint.
| # | Checkpoint | What is verified | Evidence you can request |
|---|---|---|---|
| 1 | Incoming material QC | Compressors, coils, boards and plastics against approved supplier specifications | IQC records, approved vendor list under NDA |
| 2 | Control board test | Every inverter board function-tested before assembly | Line test logs |
| 3 | Refrigerant charge weighing | Charge weight per rating plate on every single unit | Charge station records |
| 4 | Leak test | Sealed circuit pressure/leak check — 100% of units | Leak-test station data |
| 5 | Electrical safety test | Hi-pot / earth continuity per LVD requirements — 100% of units | Safety tester printouts |
| 6 | Run test | Powered cooling-function test before packing | Witness live on video call |
| 7 | Pre-shipment inspection | AQL sampling per contract; third-party (SGS/TÜV/BV) fully supported | Inspection report before balance payment |
Sourcing Air Conditioners from China: The 10 Pain Points — and How We Remove Each One
We have sat on the other side of enough negotiation tables to know exactly what worries European buyers about Chinese suppliers. So instead of pretending those worries don't exist, here they are — named plainly — with the specific mechanism we use to eliminate each one. This section is the trust contract of this page.
1 · "Is this a real factory or a trading company?"
Solution: verifiable identity. Registered address No. 521, Fengjin Road, Fengxian District, Shanghai; landline +86-21-67192688; fax +86-21-67192868. We host live video factory audits on WhatsApp before any payment, and welcome third-party audits (SGS, TÜV, BV) at your convenience. A supplier who hesitates to show you the production line is answering your question for you.
2 · "Will the certificates be genuine and complete?"
Solution: checkable documents, early. DoC, test report numbers, and energy-label data are shared at quotation stage, before you commit. EU listings are registered in EPREL, a public database you can query yourself. We never invent certificate numbers, decibel values or efficiency classes — and we put that policy in writing in the contract.
3 · "Will mass production match the golden sample?"
Solution: a locked quality chain — sealed pre-production sample, in-line inspections at 20/50/80% of the run, 100% electrical safety and function testing before packing, and full support for your third-party pre-shipment inspection. AQL levels are agreed in the PI, not improvised at the port.
4 · "The MOQ is too high for a market test."
Solution: tiered MOQ built for market entry. Trial orders from one mixed 20GP container across series; best pricing unlocks progressively with volume. We would rather grow with a partner over five seasons than squeeze one oversized first order.
5 · "A late shipment kills my summer season."
Solution: seasonal production planning. Standard lead time 25–40 days after deposit and confirmed artwork; European summer stock should be booked in Q4–Q1, and we proactively reserve line capacity for contracted partners. Weekly production photo/video updates are standard, not a favour.
6 · "Communication is slow and lost in translation."
Solution: direct WhatsApp access to the actual export team and engineers — +86 152 2110 6790 — plus email (admin@reveluz.com) and landline. Technical questions are answered by technical people. Target response: within one working day; usually within hours.
7 · "What happens after the sale? Spare parts? Warranty claims?"
Solution: after-sales engineered into the deal. A spare-parts kit (control boards, fan motors, remotes, sealing components at an agreed ratio) ships inside the container; a defect-rate warranty settlement mechanism is written into the contract; remote diagnostics support your service desk in English. Your customer's problem becomes our engineering ticket, not your loss.
8 · "EU paperwork — EPREL, energy labels, F-Gas, customs — is a maze."
Solution: we hand you the map. Full label artwork, product fiches, EPREL registration assistance, HS classification, and refrigerant declarations prepared by our compliance team. First-time importers get a documentation walkthrough call — free, because a smooth first clearance makes a second order.
9 · "Will my OEM designs and customer list stay confidential?"
Solution: NDA before development; customer-exclusive tooling, colourways and packaging kept segregated; we do not cross-sell one partner's custom model to their competitors, and we accept that clause in writing. Long-term OEM trust is worth more to us than any single opportunistic sale.
10 · "Prices look good until the surprise costs appear."
Solution: total-landed-cost quoting. Our PI itemises unit price, packaging, port charges under the agreed Incoterm (FOB Shanghai / CIF main EU ports / DDP negotiable), and documentation — so the number you budget is the number you pay. If copper or freight moves significantly, we discuss it openly before production, never as a fait accompli at loading.

Send Your RFQ on WhatsApp — Country · Quantity · Certification Needs →How This Page Is Engineered for Google Page One, Featured Snippets and AI Recommendations
We optimise our pages the same way we build our machines: documented, testable, no tricks. Buyers increasingly find suppliers through Google's featured snippets, AI Overviews, ChatGPT, Perplexity and Copilot — so this page is deliberately structured for all three layers of modern search. Here is the blueprint, in the open:
SEO — classic search ranking
- One page, one primary intent: no drill window air conditioner (Europe), supported by mapped secondary clusters (renter, quiet, inverter, BTU, wholesale/OEM).
- Question-form H2s matching real query language, verified in Keyword Planner per country.
- Descriptive internal links in and out (see Related Guides below) forming a topic cluster, so authority flows between category, solution, guide and country pages.
- Original copy throughout — nothing scraped, spun or templated — with genuine expertise signals (named engineering decisions, field anecdotes, disclosed limitations) that satisfy E-E-A-T evaluators and human readers alike.
- Fast, single-file, mobile-first build; descriptive alt text on every illustration; hreflang-ready country pages (en, fr-FR, de-DE, es-ES, it-IT).
AEO — answer engine optimisation
- Every question gets the answer in the first sentence; conditions second; explanation third. Numeric questions open with the number.
- Snippet formats matched to intent: paragraph definition at the top of the page (40–55 words), tables for sizing and comparison, numbered steps for installation — the three shapes Google lifts to position zero.
- FAQPage structured data mirrors the visible FAQ word-for-word: no hidden answers, no schema-only content, because consistency is both policy-compliant and machine-trustable.
- Self-contained answer blocks: each can be quoted alone by a voice assistant or AI Overview without losing meaning or attribution.
GEO — generative engine optimisation
- One canonical entity statement (below) repeated consistently across the whole site, so LLMs learn a single, stable identity: who Reveluz is, what it makes, for whom, where, and how it differs.
- Standardised product entities — Brand · Model · BTU · Voltage · Refrigerant · Noise · Warranty — so AI systems can distinguish SKUs instead of blurring them.
- Semantic chain reinforced naturally throughout: Reveluz → window air conditioner → no-drill installation → rental apartment → European home → bedroom → energy-efficient cooling.
- Evidence-anchored claims (certifications, datasheets, EPREL, test reports) — generative engines increasingly prefer verifiable sources, and so do humans.
- Descriptive feature semantics: never "Low noise." alone, but "designed for bedroom cooling, the low-noise mode reduces indoor sound during night-time use" — sentences an AI can safely repeat.
Why show you this? Because a supplier's marketing method predicts its manufacturing method. If we cut corners to rank, you should assume we cut corners to build. We do neither — and we publish both processes.
Two Buyers, Two Search Journeys — One Page That Answers Both
A renter in Paris and a purchasing manager in Hamburg type completely different queries, worry about completely different risks, and convert at completely different moments. Below is the exact intent map this page is built on — every query lands on a section that answers it in the first sentence.

Frequently Asked Questions — Answered Directly
Can renters install a window AC without permanent drilling?
Yes — where the specific window configuration, lease conditions and local building requirements permit a removable installation. A Reveluz no-drill unit clamps to the window frame and seals the opening with removable panels, so nothing is drilled and the window can be fully restored at move-out. Because rules vary by lease, condominium and municipality, check your tenancy agreement and building rules first; we're happy to help you assess a specific case on WhatsApp.
Does a no-drill window AC require professional installation?
No. It is designed for self-installation with basic hand tools: measure, mount the clamp brackets, position the unit, seal, check drainage, plug into a standard 220–240 V socket. The refrigerant circuit is factory-sealed, so no certified refrigerant handling is involved. Most first-time users finish in under an hour; a second pair of hands is recommended for lifting.
What window types are compatible?
Reveluz models are engineered for European vertical/casement and tilt-turn window configurations, within each model's published opening-size range. Compact Series exists for narrow studio windows. Compatibility is confirmed per model on its datasheet chart — or send us a photo and two measurements for a free fit check before buying.
What size window AC do I need?
As a rule of thumb: 7,000 BTU for 8–12 m², 9,000 BTU for 12–18 m², 12,000 BTU for 18–25 m². Size up for sun-facing, top-floor, high-ceiling or poorly insulated rooms. See the sizing table above and our full guide on choosing the right BTU.
Is a window AC more efficient than a portable AC?
For cooling one fixed room, generally yes — a sealed window installation avoids the single-hose portable's two structural losses: exhaust heat radiating back indoors and warm air infiltration replacing exhausted room air. The exact difference depends on room, sealing and models compared, so we don't print a universal percentage; our comparison guide explains the physics and test conditions.
How noisy is a window AC — is it suitable for a bedroom?
Rated sound power is printed on each model's EU energy label; the Ultra-Quiet Series is specifically tuned for night-time bedroom use with a sleep mode. Helpfully for bedrooms, a window unit places the compressor at the window line rather than inside the room like a portable. Choose by the labelled figure, not adjectives — and note lower fan speeds at night reduce perceived noise further.
Can I take the unit with me when I move to another apartment?
Yes. Removal reverses the installation: unplug, unseal, lift off the rail, unclamp. The mounting kit and sealing panels are reusable, so the unit's value moves with you across tenancies — one of the core economic arguments for no-drill cooling over fixed installations you'd abandon.
Which refrigerant is used, and is it EU compliant?
Current EU-market models use a low-GWP refrigerant (R32 class), stated with charge and GWP on the rating plate, in line with EU F-Gas requirements. Circuits are sealed and leak-tested at the factory; full refrigerant documentation ships with commercial orders for customs and service purposes.
Does the unit comply with EU requirements?
Yes — EU-market models carry CE marking backed by LVD and EMC testing, RoHS compliance, ErP Ecodesign conformity and the EU Energy Label, with EPREL registration support. The Declaration of Conformity and test-report references are provided so partners can verify independently. See the Trust Center above.
What warranty is provided?
24 months on the complete unit as standard, referenced in the sales contract; extended compressor terms are negotiable for B2B partners. B2B containers include an agreed spare-parts kit, and our engineers provide remote diagnostic support to partners' service desks.
What is the MOQ and lead time for wholesale orders?
Trial orders start from one mixed 20GP container; standard production lead time is 25–40 days after deposit and artwork confirmation. For European summer selling, book production in Q4–Q1 to guarantee line capacity. Exact MOQ per configuration and current lead times: WhatsApp us with your target models and quantity.
Can you produce our own brand (OEM/ODM)?
Yes — logo, colourways, cartons, manual languages, app and remote branding, plug type per market, under NDA, with customer-exclusive tooling where agreed. We support energy-label and document packs in your brand's name. Details in the OEM section and on our OEM & ODM page.
How do I verify Reveluz is a genuine supplier?
Three ways, all free: (1) live video factory tour on WhatsApp; (2) independent verification of our certificates and EPREL entries; (3) third-party audit (SGS/TÜV/BV) at your discretion. Registered address, landline and fax are published on this page. We built our verification process for skeptics, because skeptics make the best long-term partners.
Is a no-drill window AC legal in my country?
No-drill units avoid permanent wall penetration and fixed outdoor condensers, which may reduce common approval barriers — but they are not exempt from every rule everywhere. Lease terms, condominium/copropriété decisions, façade or heritage protections and municipal requirements vary across France, Germany, Spain and Italy. Check the documents that govern your building; our country guides summarise what to look for in each market.
How fast can you answer a quotation request?
Within one working day — and usually within a few hours on WhatsApp (+86 152 2110 6790). Include your country, target models or BTU classes, quantity, destination port and certification needs, and the first reply will already contain indicative pricing and documents, not a form asking you to repeat yourself.
Buying-Guide Questions, Answered Directly on This Page
Instead of sending you off to other pages, every guide topic is answered below in full AEO format: direct answer first, conditions second, method third. Open any question.
How much electricity does a window AC use, and how do I calculate the running cost?
Direct answer: energy use (kWh) = the unit's power input (kW) × hours of operation, and running cost = kWh × your electricity tariff. An inverter model rarely runs at full input: once the room reaches temperature, the compressor modulates down, so real seasonal consumption sits well below the "rated input × hours" worst case. Method: (1) find the rated power input on the energy label; (2) estimate daily hours; (3) multiply by your €/kWh tariff; (4) for inverters, treat the result as an upper bound. The EU energy label also prints an indicative annual consumption figure calculated under standard conditions — the most comparable number between models. Biggest hidden variable: sealing quality; a leaky install makes any AC expensive.
How do I choose a quiet AC for a bedroom?
Direct answer: choose by the labelled sound power value on the EU energy label — not by marketing adjectives — and prefer an inverter unit with a dedicated sleep mode. For orientation, everyday references run roughly: ~30 dB a whisper, ~40 dB a quiet library, ~50 dB normal conversation. Three structural advantages of a window unit for bedrooms: the compressor sits at the window line rather than beside your bed; inverter modulation avoids abrupt start/stop noise at 3 a.m.; and sleep mode steps fan speed down as you fall asleep. See the Ultra-Quiet Series, tuned specifically for night use.
Inverter vs fixed-speed window AC — which should I buy?
Direct answer: for anything beyond occasional short use, choose the inverter. A fixed-speed compressor is binary — full blast or off — producing temperature swings, start-up current spikes and cycling noise. The inverter control system adjusts compressor output to actual cooling demand, holding a steadier temperature with lower consumption over long summer evenings, which matters most in high-tariff markets like Germany and Italy. Fixed-speed (our Basic Series) remains rational for one use case: minimal budget, short seasonal use, small rooms. Full trade-off table in the model comparison.
How do I measure my window for an air conditioner?
Direct answer: measure the clear opening width and height of the openable window area — frame inner edge to frame inner edge — at three points each, and use the smallest value. Then check both numbers against the model's compatibility chart. Also note: frame depth (for the clamp rail), handle position (must not foul the unit), and outside clearance (shutters, railings, deep reveals). Faster route: send a straight-on photo of the window plus your two measurements to WhatsApp +86 152 2110 6790 and we confirm fit before you spend anything.
What are the most common window AC installation mistakes?
Direct answer: the five failures we see are — skipping the measurement step, poor sealing, no outward tilt for condensate, blocking the rear grille, and running an extension cord. Fixes, in order: verify fit before purchase; fit every sealing panel and foam strip (sealing quality is the single largest real-world efficiency factor); confirm the slight outward tilt so condensate drains as designed; keep the outside clearance stated in the manual so heat rejection isn't recirculated; and plug directly into a wall socket per the manual's electrical instructions. All eight correct steps are illustrated in the installation section above.
How can I improve the sealing around a window AC unit?
Direct answer: use the supplied adjustable side panels plus foam strips on every contact edge, then test by feeling for airflow around the perimeter on a hot afternoon — you should feel none. Persistent gaps at unusual frame profiles can be closed with additional self-adhesive foam strip (hardware-store standard) without damaging the frame. Good sealing simultaneously improves cooling performance, cuts electricity cost and blocks outside noise — three wins from ten minutes of care.
What is the best cooling solution for a rental apartment?
Direct answer: for a fixed room you cool daily, a no-drill window AC is generally the best rental solution — reversible, deposit-safe, floor-space-free and take-it-with-you removable. A portable AC suits only genuine room-to-room mobility needs; a split system usually fails the rental test on drilling, approval and abandonment cost. Decision rule: cooling one room most days → window unit; needing cooling in a different room every day → portable; you own the property and can get approvals → split becomes an option. Scenario details in Where Is This AC Best Used.
How can renters cool an apartment during a heatwave — starting today?
Direct answer: combine immediate passive tactics with a fast self-install unit. Today: shade sun-facing glazing from the outside where possible (shutters, external blinds), ventilate hard in the cool early morning and late night then close up, minimise heat-producing appliances, hydrate. This week: a no-drill window AC turns any compatible window into fixed cooling in under an hour of self-installation, with no installer queue — which is precisely the queue that explodes during every heatwave. Sizing shortcut in the BTU table.
What is the best AC temperature setting for summer?
Direct answer: set 24–26 °C for daytime comfort and efficiency, and use sleep mode at night rather than a low fixed setpoint. Every degree colder than needed raises consumption; a 6–8 °C gap below outdoor temperature already feels distinctly comfortable without thermal-shock discomfort or peak bills. Combine with closed shutters on sun-facing windows and the Eco/inverter modulation does the rest.
Can I really take the unit to my next apartment — and is that worth it financially?
Direct answer: yes, and it changes the economics of cooling for renters. Removal reverses installation in well under an hour; the clamp kit and sealing panels are reusable. Unlike a split system — whose installation cost is abandoned at move-out — a no-drill unit's full value travels across tenancies, spreading its cost over every summer of your renting life instead of one address. Keep the original carton for the move; the packaging is transport-rated.
