A booming sector… but not always a transparent one
In the residential HVAC world, the wall-mounted heat pump has become one of the most popular choices in Québec for home heating and cooling. But behind the seemingly simple installation lies a much more complex reality—one that many companies don’t want to talk about.
At AirGreen, we’ve seen firsthand that too many installers purposely leave out crucial information when dealing with clients. And these omissions can have serious consequences: reduced efficiency, hidden costs, warranty issues, and much more.
So here it is—uncensored—the truth most installers would rather keep quiet, but that we believe every homeowner should know before getting a wall-mounted heat pump installed in Montréal, Laval, Longueuil, North Shore or South Shore.
Secret #1: Not all brands are equal—far from it
Many installers will recommend the brand that gives them the highest profit margin, not the one that’s best suited for your home. The result? You end up with a heat pump that’s noisy, underperforming, or unsupported when it comes to replacement parts in Québec.
At AirGreen, we only work with brands that are reliable, field-tested, and proven to withstand our local climate: Fujitsu, Gree, Lennox, Bosch, Tosot, Midea, among others. And we always explain exactly why a specific model is being recommended.
Secret #2: Poor installation can void your warranty
This is one of the most common traps. Some uncertified or careless installers mess up the electrical connections, overlook proper drainage, or mount the outdoor unit on flimsy brackets. These mistakes can invalidate your manufacturer’s warranty.
At a home in Pointe-aux-Trembles, we recently had to completely reinstall an 18,000 BTU heat pump that had been done by another company: no proper drain slope, uninsulated refrigerant lines, and the compressor was mounted directly on a brick wall with no vibration dampers.
Secret #3: Noise is not a minor detail—especially in urban areas
Some installers completely overlook the sound impact of both the indoor and outdoor units. But in Montréal or Longueuil, in duplexes and row homes, a poorly placed heat pump can create serious disturbance for you—or your neighbors.
At AirGreen, every installation includes a noise analysis, with careful unit placement, anti-vibration wall brackets, and, if needed, an acoustic screen.
Secret #4: Some grants only apply to specific models
Many clients don’t realize they’re missing out on Hydro-Québec’s LogisVert grant simply because the installer sold them a non-certified unit. That’s up to $1,500 to $2,000 in lost financial aid.
At AirGreen, every wall-mounted heat pump we install is checked for program eligibility, and we support our clients throughout the grant application process.
Secret #5: Maintenance is often ignored—until it’s too late
Some installers never inform their clients that a wall-mounted heat pump needs regular maintenance. Clogged filters, dirty coils, stagnant drainage—all of these can cut performance by 30% to 40% in just one year.
At AirGreen, we offer a preventive HVAC maintenance service that includes a full inspection, professional cleaning, and performance report. A long-term peace-of-mind guarantee.
Case study: installation fixed in Saint-Eustache
A client had a 24,000 BTU heat pump installed by a low-cost company. Six months later: loud noise, humidity on the walls, and no response from the installer. Upon inspection, we found that the outdoor unit had no drainage setup and had been mounted too close to the wall, causing echo and vibration. We repositioned the equipment, re-did the drain, insulated the piping, and added a condensate pump. Since then, the client has been recommending us to everyone.
What you should always ask your installer
-
What is the brand, model, and sound level of the proposed heat pump?
-
Is it eligible for a grant?
-
Is the company RBQ-certified and licensed for electrical work?
-
Who will be doing the installation: full-time employees or subcontractors?
-
Does the price include: wall brackets, piping, insulated sleeves, freeze protection?
-
Is annual maintenance included or recommended?
-
Is there a clear after-sales support plan?
