Optimizing winter comfort starts well before the cold sets in
At AirGreen, we know that the winter performance of an HVAC system depends directly on the maintenance that was done… during summer. Contrary to popular belief, summer maintenance of a heat pump or central heating system isn’t just about air conditioning. It’s a strategic step—often overlooked—that prepares your entire system for the harshness of Québec winters, especially in Laval, where extreme temperatures demand reliable and high-performance equipment.
Why summer maintenance is crucial for winter in Laval
In Laval, winters can be brutal, with long stretches of intense cold. That’s why every part of your central heating or wall-mounted heat pump system must be in top condition well before the first frost hits. Summer is the perfect time to carry out the necessary inspections: access to outdoor components is easier, wait times for qualified technicians are shorter, and most importantly, issues can be anticipated before they become urgent in December.
What a full summer HVAC maintenance includes in Laval
During our summer maintenance visits in Laval, we carry out a thorough inspection of the entire HVAC system. Here are the key steps our technicians follow:
-
Deep cleaning of outdoor units (evaporators, condensers, fans).
-
Air filter checks and replacement if necessary.
-
Inspection of ventilation ducts, grills, and registers.
-
Check of all electrical connections and electronic components.
-
Refrigerant pressure check, especially important with new refrigerants like R-32 or R-454B.
-
Thermostat calibration to ensure optimal operation.
-
Full heating mode test, even in summer, to ensure the system responds correctly to commands.
Focus on wall-mounted heat pumps: preparing for winter in the summer
Wall-mounted heat pumps are particularly popular in Laval, mainly for their energy efficiency and compatibility with subsidy programs like LogisVert. However, these units are sensitive to dust build-up and component wear, especially since they often run year-round. A summer maintenance ensures that:
-
The heat exchanger is clean and efficient.
-
The indoor fan runs freely without excess noise.
-
The remote control or wall thermostat works without lag.
-
The heating mode is properly calibrated and responds instantly to demand.
We recently carried out a preventive summer maintenance on an 18,000 BTU Gree Extreme wall-mounted heat pump installed on boulevard Lévesque in Laval. Thanks to this maintenance, we detected a slight drop in refrigerant pressure, corrected before it caused a performance drop in winter. The client avoided a January breakdown and was able to fully benefit from the unit’s promised energy savings.
Lower energy consumption and fewer winter breakdowns
A poorly maintained system can consume up to 25% more energy to produce the same amount of heat. In addition, premature component wear—often caused by clogging or loose connections—leads to frequent and costly breakdowns. By conducting thorough summer maintenance, we ensure our clients a stress-free winter with no nasty surprises.
Real-life examples in Laval: A look back at our successful summer maintenance visits
-
Rue des Rossignols, Laval: maintenance of a Goodman central system, 60,000 BTU with ductwork. Result: 15% savings on the winter energy bill thanks to improved airflow.
-
Chomedey sector: full cleaning and calibration of a Bosch BOVA heat pump with inverter compressor. The client reported more stable performance at -20°C and quieter operation.
-
Duvernay neighborhood: maintenance of a Trane forced-air system, combined with a humidifier. We replaced a faulty temperature sensor, preventing a full system shutdown in December.
Practical tips: what can you do yourself?
While professional maintenance is essential, some simple tasks can be done by homeowners:
-
Regularly clean ventilation grills.
-
Check filters monthly.
-
Ensure there are no obstructions (plants, objects) around the outdoor unit.
-
Program the thermostat to optimize heating cycles.

At AirGreen, we recommend booking your HVAC maintenance in Laval between mid-May and the end of August. This gives you enough leeway to make repairs if needed. Plus, our availability is much more flexible in summer than in fall, which is often packed with heating system start-ups.
Subsidies and savings not to be overlooked
Some subsidy programs, like Hydro-Québec’s LogisVert program, require the equipment to be well maintained to remain eligible. Documented summer maintenance with AirGreen ensures you stay compliant and fully benefit from available incentives.
