A must-read guide to avoid unpleasant surprises during an HVAC installation in Montréal, Laval, Longueuil, North Shore and South Shore
Installing a wall-mounted heat pump in a climate like Québec’s is not something you improvise. While it’s easy to find an installer online, finding one who combines technical skill, regulatory compliance, transparent pricing, and in-depth knowledge of local rebates is much harder. At AirGreen, we’ve been called too often to fix incomplete, inefficient, or non-compliant installations, sometimes rushed or done without consideration for the unique challenges of Montréal homes.
Before you sign a contract for your wall-mounted heat pump installation in Montréal, Laval, the South Shore, or the North Shore, here are the five essential — and sometimes uncomfortable — questions you need to ask any professional installer. The answers could save you from costly mistakes and guarantee lasting comfort in your home.
1. Are you actually certified to install wall-mounted heat pumps in Québec?
It might seem obvious, but many installers don’t hold a valid RBQ license or proper liability insurance. Some operate under another contractor’s name, which can be a serious issue if there’s ever a dispute or breakdown.
At AirGreen, we hold all the necessary professional licenses, including electrical permits for 230V hookups, which are mandatory for most high-performance wall-mounted heat pumps like Fujitsu, Gree, or Sharp models. We’re also registered as official installation partners in Hydro-Québec’s energy efficiency programs.
Why it matters: Without proper certification, you risk voiding your manufacturer’s warranty, missing out on LogisVert rebates, and being in violation of the Québec Building Code.
2. Is the model you’re recommending actually built for Québec’s cold climate?
A serious installer should be able to show you, with a spec sheet, that the wall-mounted heat pump they’re recommending is designed for Québec winters. In Montréal or on the North Shore, it’s not unusual to face temperatures below -20°C in January.
We only recommend models certified to operate down to -25°C or -30°C, with energy efficiency that remains high even under extreme conditions. For instance, the Fujitsu KZAH 12,000 BTU wall-mounted heat pump, which we recently installed in Longueuil, kept the home warm and consistent throughout a cold snap — without the need for backup heating.
Why it matters: Many units on the market are designed for milder climates. As a result, they stop heating when you need it most.
3. Can I get a rebate with this model and installation?
Many clients don’t realize they could qualify for $1,200 to $2,500 in rebates if they choose an eligible model and a recognized installer. A trustworthy professional should help you with the application, submit system performance documentation, and provide the necessary paperwork.
At AirGreen, we recently helped a couple in Saint-Léonard with the installation of a Gree Extreme 18,000 BTU wall-mounted heat pump, eligible for a $1,704 LogisVert rebate. We completed the application, submitted the tech specs, and issued all the required compliance documents.
Why it matters: Choosing the wrong unit — or using a non-accredited installer — can make you lose thousands in rebates, increasing the real cost of your installation.
4. Do you perform a thermal analysis before installation?
A professional installer should never guess your BTU requirement. Oversizing or undersizing the unit leads to:
-
Premature wear and tear
-
Uncomfortable temperatures
-
Unnecessary electricity costs
At AirGreen, we always perform a comprehensive thermal analysis: sun exposure, insulation level, number of floors, total square footage, room layout. This lets us accurately recommend the right 9,000 BTU, 12,000 BTU, 15,000 BTU, or 18,000 BTU wall-mounted heat pump for your actual needs.
Why it matters: A poorly sized unit cancels out the benefits of a good brand or model.
5. What kind of after-sales service do you offer?
Too many installers disappear once they’ve cashed the cheque. But a wall-mounted heat pump needs regular HVAC maintenance, annual inspections, and fast repair options if anything goes wrong.
At AirGreen, we provide:
-
Seasonal HVAC maintenance (filter cleaning, pressure check, performance testing)
-
Guaranteed repair service within 48 hours
-
Local support, based in Montréal, with technicians available across the North and South Shores
Why it matters: Without proper follow-up, even the best heat pump will quickly lose efficiency and longevity.
