Heat pumps have become one of the most popular systems in Quebec, both for heating and cooling. But like any appliance, they have a limited lifespan. Knowing how long a heat pump lasts and when to replace it is key to optimizing comfort and saving on energy costs.

At Tran Climatisation, our certified technicians have been helping thousands of homeowners in Montreal, Laval, the South Shore and the North Shore for over 10 years with professional heat pump maintenance, repair and replacement.

What is the average lifespan of a heat pump?

• On average, a heat pump lasts 12 to 15 years.
• High-end, well-maintained models can last up to 20 years.
• The actual lifespan depends on several factors:
  
  • Quality of installation.
  • Frequency of maintenance.
  • Climate conditions (extreme cold, humidity, ice).
  • Annual usage (heating + cooling or cooling only).
    

What are the signs that it’s time to replace your heat pump?

The most common signs identified by our experts include:

• Your system is over 12–15 years old and often breaks down.
• Your electric bills are increasing without changes in usage.
• The heat pump heats or cools less efficiently.
• You notice unusual noises (clanking, vibrations, buzzing).
• You experience frequent refrigerant leaks or electrical issues.
• Replacement parts are increasingly difficult to find.
  

Repair or replace your heat pump: how to decide?

The general rules are : 

• If the unit is less than 10 years old, repair is usually the best option.
• If it is more than 12 years old and the repair is costly, replacement is generally more cost-effective in the long run.
  

At Tran Climatisation, we always compare repair costs with the energy savings from a new unit to help you make the right decision.

What are the benefits of replacing an aging heat pump?

• Immediate reduction in energy bills with ENERGY STAR® models.
• Greater comfort: more consistent heating and stable cooling.
• Quieter operation.
• Access to subsidies (LogisVert, Chauffez Vert, Novoclimat, etc.).
• Increased resale value for your home.
