The 21 wall air conditioners in our catalogue compared on their real spec sheets, the true cost next to a heat pump, the new legal warranty and everything a proper installation must include. Answer as you scroll: your personal summary fills itself in.
The market moved fast: fewer brands still make cooling-only units, new refrigerants, a new efficiency rating and, from October 5, a warranty required by law.
A wall heat pump cools in summer and heats in winter, and it is the only one eligible for LogisVert. As a result, cooling-only units are getting rare. Six brands remain in our catalogue.
R-32 and R-454B warm the planet far less than R-410A. The 2025 rule that caps this potential on new equipment is American: in Canada, residential air conditioners using R-410A are still sold and serviced. All 21 wall air conditioners in our catalogue use it.
100-year global warming potential. The new refrigerants transfer heat well and need a smaller charge. They are never mixed with R-410A: a qualified technician is essential.
Since January 1, 2023, single-phase split air conditioners sold in Canada, ductless units included, are tested with the M1 procedure. It gives the SEER2 (efficiency over the whole season) and the EER2 (efficiency in peak heat, about 35 °C outside and 27 °C inside).
For the same unit, the SEER2 is equal to or slightly lower than the old SEER, mostly on ducted systems. Always compare SEER with SEER, and SEER2 with SEER2.
Quebec's Consumer Protection Act requires a 6-year warranty of good working order on new air conditioners and heat pumps delivered from that date: parts, labour and reasonable transport.
Two units joined by two copper lines, with no air ducts at all. Tap a step to see it on the diagram.
Simpler and more affordable than a central system, far more efficient and quieter than a portable. Answer four questions and we'll tell you straight what to look at.
No ducts. Installed in a few hours, discreet. Ideal for one or a few rooms.
Needs existing ductwork. Cools the whole house evenly, costlier installation.
No installation work, but noisy, inefficient and power-hungry. A temporary fix.

"Bigger is safer." False. An oversized unit reaches the set temperature too fast, shuts off and never gets the time to remove humidity: the air turns cold and sticky, and the bill climbs for nothing. Properly sized, it runs long, gentle cycles that dry the air.
Each dot is an air conditioner from our catalogue, placed by its sound level at low speed, the speed it runs at night. Pick the room: we keep the models in your size that make the cut.

Outside, placement matters as much as the spec sheet: anti-vibration bracket, level base, distance from neighbouring windows and your borough's by-law. Some high-end heat pumps go below 20 dB indoors.

A wall air conditioner often costs $50 to $100 less than a wall heat pump of the same capacity. But it only does one thing, it doesn't heat in winter, and Hydro-Québec pays nothing for it. Here are the real numbers, then your own calculation.
ENERGY STAR heat pump: $50 per 1,000 BTU/h of heating at -8 °C; "cold climate" type: $120. Cap: 100% of the cost before taxes. Outdoor unit of at least 12,000 BTU/h. Not ENERGY STAR: not eligible since November 26, 2025 (LogisVert Guide v1.10). Amounts are estimates, confirmed by Hydro-Québec.

A warranty has three parts: the compressor (the heart of the system, often 10 to 12 years), the parts (circuit board, fan, valves, often 10 years) and labour (1 to 10 years depending on the installer). Without labour coverage, every visit can cost several hundred dollars. Here is what our six brands really give you.
Code shown on our spec sheets: compressor · parts · labour. Our sheets also list an optional 10-10-10 extended warranty: ask for its conditions in your quote.

| Type | Who pays | Strength | Watch out for |
|---|---|---|---|
| Manufacturer's warranty | The manufacturer (GREE, Zephyr, Goodman…) | The strongest over time | Valid only if the installer holds the RBQ licences and the unit is registered on time |
| "In-house" warranty | The installing company | Often covers labour | Disappears if the company closes; sometimes excludes travel or diagnosis |
| External insurance or plan | A third party (extended warranty plan) | Labour and some parts for several years | Deductible, exclusions, geographic limits |
| Legal warranty (from Oct. 5, 2026) | The merchant or the manufacturer, your choice | 6 years, parts and labour | Excludes misuse and normal maintenance |
Most manufacturers require the unit to be registered within 30 to 60 days, with the serial numbers, the installation date and the contractor's RBQ licences. Without it, your warranty may only exist "verbally".
At AirGreen, every installation is registered with the manufacturer, free of charge, with written proof of activation.
True or false? Read a warranty like a pro.
Answer the five statements.
The best air conditioner becomes a nightmare if it's badly installed. A mid-range unit put in by a skilled team works better, uses less and lasts longer. Switch between a good and a bad installation, then tap a point.
These licences guarantee the work meets Quebec standards, the manufacturer's warranty stays valid and you're protected if something goes wrong. AirGreen holds all three: RBQ licence 5645-9605-01.
Does your installer pass the test? Tick what you've already been given.
Well maintained, a wall air conditioner keeps its ability to cool and dry the air for years. Quebec case law has already set 12 to 15 years as a reasonable lifespan for a wall air conditioner.
Filtered on your size and noise threshold, sorted by efficiency. Air conditioners alone: $0 from LogisVert.
The price depends on capacity (9,000 to 24,000 BTU), brand, line-set length, wall access and the electrical hook-up. We do the estimate on site for free and you get a detailed written quote within 24 hours, with warranties and options, before anything is signed.
No. LogisVert only funds ENERGY STAR certified heat pumps: $50 per 1,000 BTU/h of heating capacity at -8 °C, or $120 for the "cold climate" type, up to 100% of the cost before taxes. The outdoor unit must be at least 12,000 BTU/h and the application must be filed within 9 months of installation.
They look alike and install the same way. The air conditioner only cools. The heat pump cools in summer and heats in winter, and it's the only one eligible for LogisVert. For a room that also needs heat, the heat pump is almost always the better deal.
According to ENERGY STAR, 450 to 550 sq. ft. need about 12,000 BTU/h and 700 to 1,000 sq. ft. about 18,000 BTU/h. Take off 10% for a heavily shaded room, add 10% if it's very sunny, 600 BTU per person beyond two and 4,000 BTU for a kitchen. Our estimator confirms on site: insulation, ceilings, windows.
A few hours for a simple install: one wall, one indoor unit, one outdoor unit. Access, line-set length, the drain and the electrical hook-up can make the day longer. Everything is spelled out in the quote.
Yes. As it cools, it condenses moisture from the air and drains it away. Properly sized, it runs long, gentle cycles that help keep the air around 40 to 50% humidity. Oversized, it shuts off too soon and leaves the air damp.
No. The rule that took effect in 2025 (a warming-potential cap on new equipment) is American. In Canada, the federal halocarbon regulation sets no limit for residential split air conditioners. Manufacturers are still moving to R-32 and R-454B, whose warming potential is 68% to 78% lower than R-410A's.
For new air conditioners and heat pumps delivered from October 5, 2026, the Consumer Protection Act requires a 6-year warranty: parts, labour and reasonable transport. You choose whether to claim from the merchant or the manufacturer. It excludes misuse and normal maintenance, and its duration must be shown next to the price.
It's the code shown on our spec sheets, in the order compressor, parts, labour: 10 years on the compressor, 10 years on parts, 0 years of manufacturer labour. Labour therefore depends on the installer. The "0" is the line to read first on a quote.
In Quebec, a wall installation involves ventilation (RBQ 15.8), refrigeration (RBQ 15.10) and electrical work (subclass 16, contractor member of the CMEQ). AirGreen holds all three under RBQ licence 5645-9605-01. Without them, the manufacturer can refuse a warranty claim.
Since January 1, 2023, single-phase split air conditioners sold in Canada, ductless units included, are tested with the M1 procedure, which gives the SEER2 rating (regulatory minimum 13.4). Many spec sheets still show the old SEER: always compare SEER with SEER and SEER2 with SEER2.
Look at the indoor unit's low-speed value, the one it runs at night. In our air conditioner catalogue, it ranges from 24.5 dB (Goodman 12,000) to 36 dB (24,000 BTU models). For a bedroom, aim as low as possible and don't oversize: a unit that's too big runs louder and dehumidifies poorly.
Yes: in our catalogue, the Zephyr 12,000 BTU and the Goodman 19 12,000 BTU come in 115 V. They still need a dedicated circuit; our electrician checks your panel during the estimate.
Wash the indoor filters as soon as they look grey, following the manufacturer's manual, and keep the outdoor unit clear. A yearly professional service checks the charge, pressures and connections and deep-cleans the coils, to keep efficiency up and avoid breakdowns in the middle of a heat wave.
Properly installed and maintained, 10 to 12 years or more. Quebec case law has already set 12 to 15 years as a reasonable lifespan for a wall air conditioner. The environment matters: near the river or downtown, more regular maintenance extends its life.
It depends on your borough or municipality: several regulate where outdoor units go and how loud they are, and some require a permit. We check your area's by-law during the estimate.
