Understanding the Difference
Gas Furnace vs. Cold Climate Heat Pump
Watch for These Indicators
Signs Your Heat Pump Needs Service
Recognizing early warning signs can prevent a minor issue from becoming a costly emergency. If you notice any of the following, contact our team for a professional assessment.
Insufficient Heating or Cooling Output
If your heat pump is running but not reaching your set temperature, it may have a refrigerant leak, a failing compressor, or a defrost cycle issue that requires professional diagnosis.
Constantly Running Without Reaching Setpoint
A heat pump that runs continuously without achieving the desired temperature is working inefficiently. This could indicate refrigerant loss, a dirty coil, or an undersized system.
Ice Buildup on the Outdoor Unit
Some frost during heating mode is normal, but heavy ice accumulation that does not clear during defrost cycles indicates a defrost control failure or refrigerant issue.
Sudden Increase in Electricity Bills
An unexplained spike in electricity consumption during heating or cooling season suggests your heat pump is losing efficiency and may need refrigerant, coil cleaning, or component repair.
Unusual Sounds During Operation
Grinding, squealing, or rattling sounds from either the indoor or outdoor unit indicate mechanical wear, loose components, or debris in the fan — all requiring prompt attention.
System Over 12 Years Old
Heat pumps typically last 12–15 years. An aging system loses efficiency and reliability. A proactive assessment can identify whether repair or replacement offers better long-term value.

Frequently Asked Questions
Do heat pumps work in Canadian winters?
Modern cold-climate heat pumps absolutely work in Canadian winters. Lennox's top models are rated to -30°C and maintain high efficiency even at -15°C. Many GTA homeowners use them as their primary heat source year-round.
How much can I save with a heat pump?
Heat pumps can be 2–3x more efficient than gas furnaces, potentially cutting your heating costs by 30–50%. Combined with government rebates, the payback period is often 5–8 years.
What government rebates are available?
Ontario's Home Efficiency Rebate Plus (OHERplus) and utility programs such as Toronto Hydro and Enbridge Gas offer rebates on qualifying heat pumps. The Canada Greener Homes Grant has closed; the Canada Greener Homes Loan may still be available. We stay current on all active programs and help with the paperwork.
Can I keep my gas furnace with a heat pump?
Yes — a dual-fuel system pairs a heat pump with your existing gas furnace. The heat pump handles most of the year efficiently, and the furnace provides backup on the coldest days. This is often the most cost-effective approach.
How long does heat pump installation take?
A standard heat pump installation takes 6–8 hours. If you're adding a heat pump to an existing forced-air system, it's often a straightforward swap of the outdoor unit.
