Heat Pump Installation in London, ON: Do They Work in Canadian Winters?
The most common question London homeowners ask about heat pumps is whether they can handle Ontario winters. The answer is yes. Modern cold-climate air source heat pumps from Ruud, Napoleon, Mitsubishi, and Daikin are specifically engineered for Canadian climates, maintaining full heating capacity at -15°C and operating down to -25°C to -30°C. These are not the heat pumps of 20 years ago. Corner Gas HVAC will match your home to the right cold-climate model based on your home's heat loss calculation, ensuring reliable comfort through every London winter without a gas furnace backup.
Heat Pump Cost and Ontario Rebates: What London Homeowners Need to Know
A standard air source heat pump installation in London, ON typically costs $4,000 to $10,000 before rebates, depending on system size, brand, and whether ductwork modifications are required. After applying the Canada Greener Homes Grant (up to $5,000), Enbridge Gas rebates, and the Ontario Electricity Rebate, many London homeowners reduce their net installation cost by 30–50%. Homes currently heated with oil may qualify for the Oil to Heat Pump Affordability Program, which provides up to $10,000. Corner Gas HVAC will identify every rebate you're eligible for and handle the application paperwork.
Ducted & Ductless Heat Pumps for London Homes
London homes with existing ductwork can integrate a ducted air source heat pump directly into their current system, replacing or supplementing the furnace and AC with a single efficient unit. Homes without ductwork, including older London homes with radiators or electric baseboard heating, are ideal candidates for ductless mini-split heat pumps. Mini-splits provide independent temperature control in each zone, operate near-silently, and can be installed without any ductwork modifications. Corner Gas HVAC installs both ducted and ductless systems and will recommend the right approach for your home's layout.

Call (519) 649-0166Yes. Modern cold-climate heat pumps are designed to operate efficiently at temperatures as low as -25°C to -30°C. Brands like Ruud, Napoleon, and Mitsubishi offer cold-climate models specifically engineered for Canadian winters. In most cases, a heat pump can be your primary heating source year-round in Ontario.
A standard air source heat pump installation in London typically ranges from $4,000 to $10,000 depending on the size of your home, the system selected, and whether ductwork modifications are needed. After available rebates (up to $5,000 from the Canada Greener Homes Grant), the net cost can be significantly lower.
In most cases, yes. A properly sized cold-climate heat pump can serve as your primary heating source, eliminating the need for a gas furnace. Some homeowners choose a 'dual-fuel' setup where the heat pump handles most heating and a gas furnace provides backup on the coldest days, this can be the most cost-effective approach depending on gas and electricity rates.
Savings depend on what you're replacing. Homeowners switching from electric baseboard heating typically save 40–60% on heating costs. Those switching from natural gas may see modest savings or break even on heating, but gain air conditioning they didn't have before. The long-term savings on cooling plus available rebates usually make the switch financially attractive.
The Canada Greener Homes Grant offers up to $5,000 for eligible heat pump installations (subject to a pre-retrofit home energy assessment). The Oil to Heat Pump Affordability Program offers up to $10,000 for homes currently heated with oil. Some municipalities and utilities offer additional incentives. We'll help you navigate the available programs.
A well-maintained heat pump typically lasts 15 to 20 years. The outdoor unit is exposed to the elements year-round, so regular maintenance, including coil cleaning, refrigerant checks, and electrical inspections, is important for maximizing lifespan. Our maintenance plans are designed to keep your heat pump running efficiently for as long as possible.
A standard air source heat pump installation typically takes one full day (6 to 8 hours). This includes removing any existing outdoor equipment, installing the new outdoor and indoor units, running refrigerant lines, making electrical connections, and commissioning the system. More complex installations involving ductwork modifications or multi-zone mini-split systems may take two days.
It depends on your current panel capacity. Most heat pumps require a dedicated 240V circuit, typically 30 to 60 amps. If your panel is older or already near capacity, an upgrade may be needed. We assess your electrical situation during the pre-installation consultation and will let you know upfront if any electrical work is required before installation day.
A single-stage heat pump runs at full capacity or not at all, which can cause temperature swings and higher energy use. A two-stage unit has a low and high setting, running at low capacity most of the time for better comfort and efficiency. A variable-speed (inverter-driven) heat pump adjusts its output continuously to match the exact heating or cooling demand, delivering the best comfort, quietest operation, and highest efficiency. We recommend variable-speed models for most London homes.
