How Long Do Heat Pumps Last in Nova Scotia’s Climate?
The average heat pump lifespan in Nova Scotia is 12 to 20 years, depending on installation quality, maintenance, insulation levels, and system type. Cold-climate heat pumps installed by certified contractors and paired with proper insulation and ventilation upgrades can exceed 20 years of service, while poorly installed systems may fail in under 10 years.
Heat Pump Lifespan in Nova Scotia — What Homeowners Need to Know
Heat pump lifespan in Nova Scotia is directly affected by long winters, coastal moisture, salt air exposure, and home insulation quality. Because heat pumps operate year-round for both heating and cooling, they experience more run-time hours than traditional furnaces — making proper installation and sizing critical to long-term durability.
Older Nova Scotia homes with poor insulation force heat pumps to run continuously, increasing wear and shortening system lifespan. Quinn Energy designs systems that match the thermal needs of Maritime homes, preventing premature equipment failure.
Average Heat Pump Lifespan by System Type
| System Type | Typical Lifespan |
|---|---|
| Mini-Split Heat Pump | 15 – 20 years |
| Central Heat Pump | 12 – 18 years |
| Poorly Sized / Installed Systems | 7 – 10 years |
What Shortens Heat Pump Lifespan?
• Oversized or undersized systems
• Inadequate insulation and air sealing
• Lack of HRV ventilation
• Moisture infiltration
• Poor maintenance habits
These factors are common in coastal Nova Scotia properties.
How to Extend Heat Pump Lifespan
✔ Install spray foam insulation
✔ Add HRV ventilation systems
✔ Schedule annual maintenance
✔ Proper system sizing
✔ Professional installation
Quinn Energy integrates insulation and ventilation upgrades with heat pump installations to extend equipment life while lowering operating costs.
When Should a Heat Pump Be Replaced?
You should consider replacement if:
• Your system is over 12 years old
• Your power bills are rising
• Heating output is inconsistent
• Repairs are becoming frequent
