Thorough Maintenance for Maximum Efficiency of Your HVAC System
At AirGreen, we know that regular maintenance of a central heat pump is essential to ensure optimal performance, extend the lifespan of the equipment, and prevent costly breakdowns. Whether you live in Montréal, Laval, Longueuil, the North Shore, or the South Shore, following proper maintenance practices can make all the difference between an efficient system and an underperforming unit.
In this article, we share 7 technical and practical tips based on our field experience to help you keep your central heat pump in top condition, while saving on your energy bills.
Why is maintaining your central heat pump so important?
A poorly maintained central heat pump can lead to performance issues, excessive energy consumption, and premature wear of essential components. At AirGreen, we’ve seen customers experience major failures that could have easily been avoided with preventive service visits.
Moreover, proper maintenance is often required to uphold the manufacturer’s warranty and may also be a condition for eligibility for certain grant programs such as Hydro-Québec’s LogisVert.
1. Clean or replace air filters regularly
Clogged air filters reduce airflow and force the system to work harder, increasing electricity use and reducing comfort. We recommend:
-
Checking filters monthly during peak usage seasons.
-
Cleaning or replacing them based on the manufacturer’s guidelines.
-
Using filters with a MERV 8 rating or higher, depending on the system.
During a maintenance call in Brossard for a 36,000 BTU Goodman central heat pump, we found the client had never changed their filters in two years. After cleaning, the system was back at full capacity, with a measurable 12% gain in energy efficiency.
2. Check the evaporator and condenser coils
The coils are responsible for heat exchange. When they’re dirty, efficiency drops. At AirGreen, we use specific, non-corrosive products to clean them during every maintenance visit.
During a maintenance call in Laval for a Bosch BOVA R-454b central heat pump, we removed a thick layer of dust and pollutants. The result: immediate improvement in airflow and a return to more stable indoor temperatures.
3. Make sure the condensate drain is clear
The water generated during the cooling process needs to drain properly. A clogged drain can lead to leaks, mold growth, and unpleasant odors inside your system.
-
Regularly inspect the drainage pipe.
-
Clean it using a wet/dry vacuum if needed.
-
Upon request, we can install an automatic overflow detection system.
4. Check the motor belt’s condition and tension
On some older models or forced-air systems, the motor belt can wear or loosen, affecting fan performance.
-
Have the alignment and tension checked during your annual service.
-
A worn belt can cause noise, vibrations, and premature motor failure.
We recently serviced a Fujitsu KZAH R-32 central heat pump in Longueuil where a worn belt was causing loud metallic noises. A quick repair restored smooth and quiet operation.
5. Schedule a professional HVAC maintenance visit once a year
While some maintenance tasks can be handled by the homeowner, nothing beats a professional annual inspection. Our certified technicians check:
-
Refrigerant pressure levels (especially important for systems using R-32 or R-454b)
-
Thermostat functionality
-
Electrical connections
-
Overall system performance
Every visit includes a detailed report and tailored recommendations.
6. Pay attention to unusual noises or vibrations
Sudden noises can indicate mechanical issues, an unbalanced fan, or a failing compressor. In Saint-Eustache, we diagnosed a failing compressor on a 5-ton Trane central heat pump thanks to a simple client complaint about a metallic noise.
Result: preventive compressor replacement, avoiding a full system failure in the middle of winter.
7. Clear the outdoor unit and inspect its surroundings
Your outdoor unit should always have a minimum clearance of 60 cm (24 inches) all around and above. Removing debris, leaves, snow, or vegetation is essential to:
-
Ensure proper airflow
-
Prevent coil freezing in winter
-
Avoid premature fan wear
We also recommend installing a protective cover or overhang for clients on the North Shore and South Shore, where snow buildup can be significant.
