Expert advice to maximize the performance of your heat pump in urban or suburban settings
In Montréal and its surrounding areas — whether on the North Shore, the South Shore, in Laval, or in Longueuil — the varied climate requires a smart use of HVAC systems, especially wall-mounted or central heat pumps. At AirGreen, we regularly meet homeowners and property managers who ask us how to improve the energy efficiency of their system, reduce heating costs, and extend the lifespan of their heat pump. So here is a comprehensive guide, based on our field experience and technical know-how, to help you get the most out of your system.
Understanding the basics: how it works and what efficiency means
A heat pump works by transferring heat from one place to another, depending on the season. In the summer, it removes indoor heat and expels it outdoors to cool your home, and in the winter, it draws in heat from outside to warm your space. Its performance is measured using indicators like SEER (Seasonal Energy Efficiency Ratio) for cooling, and HSPF (Heating Seasonal Performance Factor) for heating.
A modern high-efficiency heat pump — like the Fujitsu KZAH R-32, Gree Extreme, Bosch BOVA, or Sharp ZU1 models — can generate substantial savings if used and maintained properly.
Tip #1: Properly size the unit from the start
One of the most critical factors is making sure the unit is properly sized. An oversized heat pump will waste energy and wear out faster, while an undersized one will struggle to maintain comfortable indoor temperatures.
At AirGreen, we always conduct a comprehensive heat load assessment before each installation. For example, during a recent project in the Ahuntsic neighborhood of Montréal, we recommended a 36,000 BTU Fujitsu central heat pump instead of the initially considered 48,000 BTU model, due to the building’s excellent insulation. That client is now saving an average of 18% on their energy bill.
Tip #2: Clean filters and coils regularly
Regular HVAC maintenance is essential to keep a heat pump running efficiently. Clogged filters or dirty coils reduce airflow and force the compressor to work harder.
We recommend:
-
Cleaning the filters every two months during peak usage.
-
Annual professional inspections to check refrigerant pressure, electrical components, and coil cleanliness.
-
At AirGreen, we offer a complete high-pressure cleaning service that includes both indoor and outdoor units.
Tip #3: Optimize your thermostat programming
Installing a smart thermostat can save up to 10% over a heating season. These thermostats automatically adjust the temperature based on your habits, local weather (Montréal, Laval, etc.), and your presence at home.
During an installation in Brossard, we integrated an Ecobee Wi-Fi thermostat into a Gree Sapphire 18,000 BTU system. The result: optimal temperature management and improved comfort, even during extreme cold spells.
Tip #4: Protect the outdoor unit from ice and snow
On the North Shore and South Shore, winters can be harsh. It’s crucial to keep the outdoor unit elevated and clear, with protection against snow and ice buildup.
Our experienced installers use galvanized raised stands, sometimes combined with small protective shelters, to ensure optimal airflow and prevent short circuits caused by moisture.
Tip #5: Properly insulate the building
Good insulation is the perfect complement to a high-performing heat pump. Even the most advanced HVAC system can’t run efficiently in a poorly insulated home.
In Longueuil, we recently enhanced the performance of a 60,000 BTU Goodman central system by recommending the addition of mineral wool insulation in the attic and sealing windows. The client reported a 25% drop in energy costs in just three months.
Tip #6: Choose units built for Québec's climate
Some heat pumps, like the Bosch BIVA IDS Premium R-454B, are designed to operate in temperatures as low as -30°C, which is essential for Montréal and the North Shore. These models feature inverter compressors that adjust speed based on actual demand, reducing energy consumption.
Tip #7: Take advantage of available grants
Programs like Hydro-Québec’s LogisVert program can offer grants of up to $2,172 for installing an eligible heat pump.
At AirGreen, we handle eligibility verification, prepare all required documents, and guide our clients through the process. A client in Laval, for example, received $1,860 for installing a Gree Extreme 24,000 BTU heat pump, and saw their energy consumption drop by 35%.
Tip #8: Monitor for unusual noises or performance issues
Unusual noises, weakened heating output, or increased power usage are often early signs of a malfunction.
Our preventive HVAC maintenance service helps detect these issues early. In Sainte-Julie, we avoided a full replacement by simply changing the control board on a five-year-old Zephyr heat pump.
