What’s Behind the Low Price of Wall-Mounted Heat Pumps Sold Online: A Reality We Know All Too Well
At AirGreen, we are frequently contacted by clients who purchased a wall-mounted heat pump online—often drawn in by a tempting price or a limited-time promotion. These clients are then looking for a contractor to handle the HVAC installation. However, we systematically refuse to install certain units, and it’s not out of snobbery or commercial interest. It’s a technical, ethical, and professional decision, based on real-world experience and a commitment to protecting our clients in Montréal, Laval, Longueuil, the North Shore, and the South Shore.
Units That Aren’t Certified or Suitable for the Québec Climate
One of the most common problems with wall-mounted heat pumps sold online is that they’re not certified for Québec’s harsh winters. Many low-cost imported models are not built to operate efficiently below -10 °C, while our winters regularly drop to -20 °C and below.
What we’ve found:
-
Units without CSA or ULC certification, making them uninsurable.
-
Manuals available only in English or poorly translated.
-
No technical support or local parts availability.
-
Claimed performance ratings (SEER/HSPF) unverified under Canadian conditions.
A client in Saint-Jérôme contacted us after installing a unit he bought online. The unit failed every time the temperature dropped below -5 °C. No after-sales service. No warranty support. He had to replace the entire system.
Questionable Build Quality
Behind a sleek design or impressive specs often hides poor build quality, with unreliable electronics, undersized compressors, or poorly assembled refrigeration circuits.
From what we’ve seen in the field:
-
Burned-out capacitors after just three weeks.
-
Noisy fans, visibly unbalanced.
-
Warped mounting plates, unable to support the unit’s weight.
-
Flimsy electrical connectors, non-compliant with Québec’s building code.
These systems don’t hold up under extended use—especially not in Québec’s winter climate.
No Technical Support or Valid Warranty
When we install a wall-mounted heat pump we didn’t supply ourselves, we can’t offer any warranty on the equipment. Even worse, foreign manufacturers often require that installation be done by their own partners in order to honor the warranty—leaving the customer in a bind.
At AirGreen, we’ve decided to no longer install equipment we haven’t supplied, except in rare cases where we’ve conducted a full inspection beforehand. This allows us to guarantee:
-
The unit’s proper functioning as specified.
-
Its suitability for the local climate and the building’s needs.
-
The safety of the electrical and refrigerant installation.
-
A complete warranty, both on labour and on equipment.
Case Study: Replacing an Online Unit in a Longueuil Duplex
A duplex owner in Longueuil ordered two wall-mounted heat pumps from an unknown brand on an Asian e-commerce site. The outdoor unit was making intense noise after the first week, and the indoor unit was blowing lukewarm air, unable to properly heat the room.
Upon inspection, our technicians found:
-
Copper piping with walls too thin, non-compliant.
-
A motherboard with no surge protection.
-
An outdoor unit without an inverter compressor, causing excessive energy consumption.
We recommended installing two Fujitsu KZAH 12,000 BTU units, certified, quiet, and efficient down to -26 °C. Result: comfort, energy savings, and a full five-year warranty.
Why Are These Units So Popular Online?
Price, plain and simple. A wall-mounted heat pump sold for $1,200 online may seem attractive compared to a model sold and installed for $3,500. But the difference lies in:
-
The quality of the internal components.
-
The availability of support in case of breakdown.
-
Compliance with local codes and regulations.
-
The actual lifespan of the system.
A low-cost heat pump often needs to be replaced after 3 to 5 years, compared to 12 to 15 years for a professional installation.
Our Position: Professional, Responsible, and Transparent
We firmly believe that the quality of an HVAC system rests on three pillars:
-
A reliable unit, certified and built for Québec’s climate.
-
A professional installation, safe and precise.
-
Local after-sales support, responsive and competent.
That’s why AirGreen strictly refuses to install wall-mounted heat pumps sold online that don’t meet these criteria.

Conclusion: Better to Prevent Than to Repair
