Extending the life of your heat pump is more than just about saving money — it’s about long-term comfort, energy efficiency, and peace of mind. At AirGreen, we operate throughout Montreal, Laval, Longueuil, the North Shore and the South Shore, and we know that the lifespan of a heat pump depends on several factors: quality of the installation, regular maintenance, operating environment, and even your everyday habits.
Here are 7 practical, technical, and sometimes surprising tips we’ve developed through our extensive experience in HVAC installation and maintenance, to help you get the most out of your equipment.
Have your heat pump inspected and cleaned at least twice a year
Regular HVAC maintenance, ideally in the spring and fall, helps prevent the buildup of dirt, dust, and mold that can hurt your unit’s performance. Our AirGreen teams offer comprehensive heat pump cleaning services, both ductless and central, throughout the Greater Montreal Area. We clean the coils, disinfect internal components, inspect electrical connections, and check refrigerant pressure.
Professional maintenance can extend your unit’s life by several years, while maintaining optimal energy efficiency.
Never delay a repair, even a minor one
Hearing a strange noise? Noticing a drop in performance? A slight musty smell? These are all subtle ways your heat pump is signaling that it needs attention. Ignoring these warning signs can lead to early failure of the compressor or the control board.
At AirGreen, we’ve seen minor repairs turn into major expenses simply because of delayed intervention. Call us at the first sign of trouble to avoid permanent damage.
Keep the area around the outdoor (and indoor) unit clear
We always advise our clients to leave at least 60 cm of clearance around the outdoor unit. Branches, leaves, debris, and even snow in the winter can block airflow. This forces your heat pump to work harder, accelerating motor wear and reducing its lifespan.
Indoors, make sure the filters are clean and that the wall-mounted unit isn’t blocked by furniture, curtains, or decorations.
Invest in a smart thermostat suited to your system
A poorly chosen or improperly set thermostat can cause your heat pump to run inefficiently. We recommend smart thermostats compatible with inverter heat pumps, which adjust power based on indoor temperature, reducing frequent on-off cycles.
This helps prevent premature wear and tear and optimizes energy consumption — a smart move for both your wallet and your equipment.
Avoid short cycling (Tip #5 — often overlooked)
Here’s the tip few people know: short cycles are hard on your heat pump. When the unit turns on and off quickly multiple times a day, the compressor experiences significant thermal stress.
This often happens when the BTU capacity isn’t properly matched to your space or if the system is poorly installed. At AirGreen, we always conduct a personalized thermal assessment before each installation to avoid this common issue, often seen with less meticulous installers.
Protect the outdoor unit from harsh winter weather
In areas like Montreal, Laval, and the North Shore, where winters are long and harsh, it’s essential to protect the outdoor unit. Installing a protective cover or hood can prevent excessive ice buildup, which can damage the fins and slow the fan.
But be careful: never cover the unit entirely, as this would block airflow and cause overheating.
Always work with certified experts for any intervention
It may seem obvious, but we’ve had to correct far too many installations rushed by unqualified contractors. A poorly executed HVAC installation — incorrect drain slope, improper sealing, mispositioned units — can cut your heat pump’s lifespan in half.
At AirGreen, all our technicians are certified and trained to the highest industry standards, with proven expertise throughout the Greater Montreal Area. We install the most trusted brands like Fujitsu, Gree, Bosch, Goodman, and Sharp, strictly following the manufacturer’s instructions and building codes.
Our seasonal tips to extend the life of your heat pump
In the spring:
-
Schedule a full maintenance appointment with AirGreen.
-
Check the condition of the condensate drains.
-
Rinse wall-mounted filters with warm water.
In the summer:
-
Don’t place the outdoor unit near a heat source (BBQ, dryer vent).
-
Keep the indoor temperature stable; avoid constant setting changes.
In the fall:
-
Clear fallen leaves around the outdoor unit.
-
Check the insulation on external lines.
In the winter:
-
Regularly remove snow buildup around the outdoor unit.
-
Never try to defrost the unit with hot water — call us if frost persists.
The AirGreen touch: excellence in every installation
We recently installed a Fujitsu 18,000 BTU KZAH series wall-mounted heat pump in Laval, in a single-family home undergoing renovation. The client wanted a quiet, efficient system, eligible for grants, and capable of effective heating during deep winter cold.
We delivered a meticulous installation, including insulated ducts, dedicated breakers, concealed piping, and an optimal unit orientation for even heat distribution. The result: a satisfied customer, lower Hydro-Québec bills, and a heat pump built to last over 15 years.
In short: taking care of your heat pump means protecting your comfort and your investment
A properly installed and maintained heat pump can last 12 to 20 years, depending on the model and usage. By following these 7 simple yet crucial tips, you maximize your return on investment, reduce your energy bills, and avoid major headaches.
At AirGreen, we don’t just sell and install — we support you throughout your equipment’s entire lifespan, with cleaning services, repairs, preventive maintenance, and personalized advice, everywhere in Montreal, Laval, Longueuil, the North Shore, and the South Shore.
