Replacing an Aging Central Heat Pump: A Unique Opportunity for Comfort and Energy Efficiency
After 15 years of reliable service, your central heat pump is starting to show signs of wear? It’s perfectly normal. The average lifespan of a CVAC central system in a climate like Montréal, Laval, or Longueuil typically ranges from 12 to 18 years. However, this critical moment also represents a unique opportunity to enhance your comfort, make significant energy savings, and take advantage of subsidies available on the North and South Shore.
At AirGreen, we assist hundreds of clients every year with the replacement of their old heat pumps, and we know exactly what to check, avoid, and optimize. Here’s everything you need to know if your unit has reached 15 years (or more).
Why Replace Your Heat Pump After 15 Years?
Over time, even high-quality systems lose efficiency:
-
Performance drops by 15 to 30%, especially in heating mode during extreme cold.
-
Energy consumption increases, often silently.
-
Breakdowns become more frequent: motors, compressors, circuit boards.
-
The refrigerant may no longer meet current standards (e.g., R-22 is banned).
-
Newer models are much quieter, more efficient, and eco-friendly.
Replacing your heat pump at this stage will help you avoid frequent repairs, reduce your electricity bills, and enjoy better thermal comfort, both in winter and summer.
Case Study: Replacing an Old Carrier Heat Pump in Laval
One of our clients in Laval had a Carrier central heat pump from 2008. The system was still running, but it was struggling to adequately heat the farthest rooms, and the noise from the outdoor compressor was becoming disruptive.
After a thorough evaluation, we recommended installing a Bosch BOVA36HDN1M20G central heat pump (36,000 BTU, R-410A refrigerant, SEER 20, HSPF 10.5), compatible with the existing electric furnace. The installation was completed in a single day.
Immediate results:
-
Comfort restored on the first day, even during a night at -18 °C.
-
29% decrease in consumption observed from the first month.
-
Noise reduced by half, with additional soundproofing.
-
Eligibility for a LogisVert subsidy of $1,720.
Key Steps for a Successful Replacement
1. Full System Evaluation
Before anything, our technical advisors perform a detailed energy analysis of your property: square footage, insulation, ducts, orientation, maintenance history. This allows us to recommend the right model, with the right capacity.
2. Duct Compatibility Check
Many existing systems can be retained, provided the ducts are in good condition, airtight, and properly sized. Otherwise, we’ll propose partial adjustments or replacements.
3. Choosing the Right Equipment
We recommend Inverter models for their ability to modulate power based on outdoor temperature, which improves comfort while reducing energy consumption.
Our recommended brands for this type of replacement include:
-
Bosch BOVA (R-410A or R-454B)
-
Goodman R-32 (excellent value for the price)
-
Fujitsu KZAH R-32 (highly efficient for cold climates)
4. Subsidy Application
If you’re replacing an old system or if your house meets certain insulation criteria, you can qualify for up to $5,000 in combined subsidies (LogisVert, Éconologis, etc.). We take care of all the paperwork for you.
5. Certified Professional Installation
Our certified technicians install your new central heat pump to industry standards, performing pressure tests, complete commissioning, airflow adjustments, and user training.
Common Mistakes to Avoid
-
Choosing a unit that is either too small or too large for your home.
-
Not checking the condition of ducts or filters.
-
Overlooking the soundproofing of the compressor.
-
Forgetting about available subsidies.
-
Hiring an uncertified or uninsured installer.
