Don’t let an unqualified installer compromise your comfort and the performance of your wall-mounted heat pump: spot these warning signs to avoid costly surprises.
In the residential and commercial HVAC sector in Quebec, the quality of the installation of a wall-mounted heat pump is just as important as the performance of the system itself. At AirGreen, we’ve had to fix countless sloppy or incomplete installations done by unqualified technicians across Montréal, Laval, Longueuil, the North Shore, and the South Shore. These mistakes can lead to reduced efficiency, premature breakdowns, or even loss of government rebate eligibility.
To help you avoid frustrating and costly situations, here are 7 hidden signs that a technician is not qualified to properly install your wall-mounted heat pump.
1. They don’t offer a pre-installation site visit
A competent HVAC professional never relies on rough measurements or photos sent by email. They absolutely must visit your home to:
-
Inspect the condition of your electrical infrastructure.
-
Confirm the space’s dimensions and insulation levels.
-
Identify any physical constraints (compressor placement, piping route, etc.).
At AirGreen, we always carry out a technical site visit before any installation to ensure everything is done optimally.
2. They never mention available rebates
A properly trained installer is familiar with Hydro-Québec’s LogisVert rebate program, as well as Rénoclimat and Transition énergétique Québec. They should be able to guide you on:
-
Whether your project is eligible.
-
The required energy efficiency ratings (e.g., SEER, HSPF).
-
The documentation needed to receive the rebate.
A technician who never brings this up is probably not certified or doesn’t fully understand today’s energy efficiency standards.
3. They don’t offer a variety of brands or models
A competent installer understands the differences between brands (Fujitsu, Gree, Midea, Lennox, etc.) and can recommend a model based on:
-
Your actual BTU needs (based on surface area and orientation).
-
Your priorities (quiet operation, cold-weather performance, smart connectivity).
-
Your budget and rebate eligibility.
A technician who only pushes one brand or offers a single option with no explanation is acting on commercial interest—not on real expertise.
4. They don’t use proper measuring tools or perform pressure tests
Installing a wall-mounted heat pump involves several technical steps that require precision tools:
-
Vacuum test using a vacuum pump to eliminate moisture.
-
Pressure test with nitrogen to check for leaks.
-
Use of a digital gauge set and vacuum gauge.
A technician who skips or rushes these steps may cause refrigerant leaks, reduced performance, and even compressor failure.
5. The outdoor installation is sloppy (bad compressor placement or support)
Out in the field, we’ve seen outdoor units installed:
-
Directly on bare ground (without a slab or supports).
-
Too close to the wall (blocking airflow).
-
Under roof gutters that drip in winter (causing water damage).
A proper outdoor installation requires careful planning, including:
-
A concrete slab or galvanized wall bracket.
-
Adequate clearance for airflow.
-
Protection from the elements (protective roof, deflector).
6. They never mention maintenance or long-term responsibilities
A serious installer will take time to explain:
-
The recommended maintenance schedule (filter cleaning, evaporator wash).
-
Warning signs to look out for.
-
What’s covered under the manufacturer’s warranty vs. the labor warranty.
At AirGreen, every customer receives a maintenance guide for their wall-mounted heat pump and an annual follow-up reminder to help maximize the system’s lifespan.
7. They avoid showing their certifications or explaining their background
A qualified HVAC professional in Quebec must hold:
-
A trade certification from the CCQ or CMEQ (depending on the work).
-
A valid RBQ license.
-
Liability insurance.
At AirGreen, all our technicians are fully certified and follow continuous training on the latest technologies like R-32 or R-454B refrigerants.
Pro tips to help you choose the right wall-mounted heat pump installer
Before signing any agreement, always ask for:
-
A detailed quote including technical specifications.
-
A clear, realistic timeline.
-
Photos of previous installations (completed in Montréal, Laval, or Longueuil).
-
A post-installation follow-up (call or site visit).
Real-world examples: AirGreen’s repair jobs after botched installations
In Brossard, we recently corrected an installation where the refrigerant pipes were run through an uninsulated attic, causing major heat loss. The client had accepted a quick quote with no inspection. After our work, the system’s efficiency doubled.
In Boisbriand, an 18,000 BTU Gree Extreme heat pump had been installed without a proper vacuum test. Result: compressor failure within six months. We completely redid the installation and ensured the client could qualify for the $1,704 LogisVert rebate after our intervention.
