Maximizing the Lifespan of Your Central Heat Pump: AirGreen’s Tips for Long-Lasting Performance in Greater Montréal
A well-maintained central heat pump can deliver reliable performance for two decades—or even longer. But the longevity of an HVAC system doesn’t just depend on the brand or power: it relies on simple, consistent, and strategic actions that we apply daily at AirGreen, across Montréal, Laval, Longueuil, as well as the North Shore and South Shore. In this article, we reveal 5 essential tips that help our clients extend the life of their central heat pump while optimizing comfort and energy savings.
1. Rely on professional preventive HVAC maintenance twice a year
Nothing replaces rigorous HVAC maintenance carried out by certified technicians. At AirGreen, we recommend a full inspection in the spring (before cooling season) and in the fall (before the heating season). This preventive schedule allows us to:
-
Detect signs of wear before they lead to costly breakdowns.
-
Clean the coils and ventilation ducts to maintain optimal airflow.
-
Check refrigerant pressure (especially with newer gases like R-32 or R-454B).
-
Adjust the system’s configuration based on how your needs evolve.
In a recent project in Boisbriand, we performed a full maintenance service on a Bosch BOVA IDS Premium 36,000 BTU R-454B central heat pump installed in 2012. Thanks to our intervention, energy efficiency was increased by 17%, while eliminating a strange noise coming from the central fan.
2. Use high-quality filters and replace them regularly
Air filters are the silent guardians of your HVAC system. Too often overlooked, they directly impact:
-
Indoor air quality,
-
Energy consumption,
-
Buildup inside system components.
We recommend replacing filters every 3 months, or more often if you have pets, allergies, or a heavily used system. During our service visit in Saint-Hubert in 2024, at a home equipped with a Goodman 48,000 BTU central heat pump, we found a completely clogged filter. After replacing it and cleaning the system, airflow returned to normal, extending the compressor’s lifespan by several years.
3. Optimize usage based on the seasons to prevent overload
One of the best-kept secrets to HVAC longevity is how you operate the system. Here are a few smart habits we recommend to our clients:
-
Program the thermostat wisely: avoid drastic temperature swings.
-
Don’t shut off the heat pump completely in winter: restarting puts extra strain on the system.
-
Maintain a stable temperature to reduce short cycling.
At a commercial client’s site in Laval, we reassessed the programming of a Fujitsu KZAH R-32 60,000 BTU system installed in 2015 in a mixed-use building. By adjusting the time slots and temperature thresholds, we reduced the number of system restarts by 40%, significantly reducing wear on the compressor.
4. Avoid installation mistakes by choosing a certified installer
Most long-term problems with central heat pumps originate from poor installation. Improper refrigerant charging, incorrect sizing, or poorly positioned ductwork can compromise the performance of a brand-new system.
At AirGreen, we carry out precise thermal load calculations and custom installation plans for every residential or commercial project. For example, during the installation of a 36,000 BTU Arcoaire system in Repentigny, we had to readjust the existing ducts to ensure optimal airflow balance in a multigenerational home. This level of precision ensures that the central heat pump operates at full capacity without overload, naturally extending its lifespan.
5. Plan for component aging and schedule targeted replacements
Even with proper maintenance, certain parts have a mechanical lifespan. We recommend planning targeted replacements (blower motors, capacitors, relays) after 10 to 12 years to avoid full system failures.
At a client’s home in Longueuil, we replaced the blower motor of a Comfortmaker 42,000 BTU system after 11 years of service. The repair was done without interrupting heating, thanks to our quick availability, and the client was able to keep their system running for another 5 years without needing a full replacement.
Why extending the life of your central heat pump is a top priority at AirGreen
Our clients are looking for reliability, performance, and return on investment, and we’ve built our reputation on those pillars. By taking a proactive, transparent, and thorough approach, we help every homeowner—whether they live in a condo in Montréal, a plex in Laval, or a family home on the South Shore—get the most out of their HVAC investment.
Real cases: heat pumps that last over 20 years
-
Pierrefonds: a 1999 Goodman still working thanks to semi-annual maintenance by AirGreen since 2005.
-
Saint-Eustache: a 2004 Bosch system kept in excellent condition with a fan replacement and upgraded duct insulation.
-
Varennes: a Fujitsu central system installed in 2003 still delivering comfort and efficiency in a 3,500 sq. ft. home.
Practical advice for homeowners
-
Set up an annual maintenance routine with a certified professional.
-
Keep a maintenance log with dates, replaced parts, and observations.
-
Don’t ignore small problems (noises, reduced airflow, odors).
-
Stay informed about available replacement grants in your area.
