Revelations from a Former Technician: 6 Hidden Mistakes Made by Heat Pump Installers in Montreal

Identify and Avoid Common Pitfalls for a Flawless Wall-Mounted Heat Pump Installation

When it comes to installing a wall-mounted heat pump in Montreal, the difference between optimal comfort and a series of costly headaches often hinges on details only an experienced technician can master. At AirGreen, we've encountered numerous homeowners frustrated by mistakes made by careless or inexperienced installers. To help you avoid these issues, we’re revealing six hidden mistakes frequently observed during service calls in Montreal, Laval, Longueuil, the North Shore, and the South Shore.

Mistake 1: Incorrect Heat Pump Sizing

One of the most common errors involves choosing the wrong capacity (BTU) for the heat pump. If it's too powerful, it creates discomfort due to short cycling, causing premature wear and excessive energy use. If it’s too weak, it struggles to reach the desired temperature, wasting energy and leaving occupants uncomfortable.

AirGreen’s Solution: We systematically perform a detailed thermal needs analysis for each home. For example, during a recent installation in Laval of a 12,000 BTU Fujitsu ASYG12KZAH heat pump, we carefully considered the area, insulation, orientation, and lifestyle of the occupants. The result: perfect comfort and notable energy savings.

Mistake 2: Poor Placement of Indoor or Outdoor Units

Many installers neglect the optimal placement of units, significantly reducing energy efficiency and acoustic comfort. An outdoor unit positioned in an area overly exposed to weather or close to windows can become a significant noise nuisance.

AirGreen’s Solution: In Longueuil, a recent installation of a Bosch Climate 5000 wall-mounted heat pump required strategic adjustments to the outdoor unit’s location. We repositioned the unit to a place sheltered from prevailing winds and acoustically discreet, substantially improving the customer's experience.

Mistake 3: Insufficient Insulation of Refrigerant Lines

Inadequate insulation of refrigerant lines is a common yet often invisible problem for customers. Poor insulation leads to thermal losses, excessive energy consumption, and even condensation risks that can cause significant property damage.

AirGreen’s Solution: During a complex installation in a duplex in Montreal's Plateau-Mont-Royal, our team meticulously insulated the refrigerant lines using certified high-quality materials, ensuring maximum and lasting performance of an 18,000 BTU Gree Sapphire wall-mounted heat pump.

Mistake 4: Neglecting Proper Air and Moisture Evacuation

Failure to adequately purge the refrigeration circuit results in premature equipment degradation. Residual moisture and trapped air lead to frequent malfunctions and significantly reduce the lifespan of the heat pump.

AirGreen’s Solution: In every installation, we use a high-performance vacuum pump and strictly adhere to the manufacturer's recommended vacuum times. This rigorous protocol notably allowed for a flawless startup of a Tosot Lomo Plus heat pump in Pointe-Claire.

Mistake 5: Overlooking Accurate Refrigerant Settings

An improper refrigerant charge is a subtle but costly mistake. Too little refrigerant results in poor efficiency, while too much negatively impacts component lifespan and thermal comfort.

AirGreen’s Solution: Every AirGreen installation systematically includes precise refrigerant charge adjustments according to the exact specifications provided by manufacturers. Recently, during an installation in Saint-Jérôme on the North Shore, we conducted a rigorous check of the refrigerant charge for a Lennox MLA heat pump.

Mistake 6: Ignoring Available Local Grants

Many installers fail to adequately inform their customers about subsidies available in Montreal, Laval, Longueuil, the North Shore, and the South Shore. As a result, customers potentially lose hundreds or even thousands of dollars in funding.

AirGreen’s Solution: Our team systematically assists each customer in identifying and obtaining available financial support, such as the LogisVert program by Hydro-Québec. A customer in Brossard thus secured a $1,704 subsidy for installing an 18,000 BTU Gree Extreme heat pump, thanks to our support.
