Heat Pump Installation in London, ON
London, Ontario heat pump installers handle a humid continental climate where modern cold-climate hyper-heat units have become economically competitive with traditional gas furnaces thanks to Save On Energy rebates and the federal Greener Homes grant (up to $5,000 CAD). Mitsubishi Hyper-Heat, Daikin Aurora, and Carrier Infinity Greenspeed are the dominant cold-climate platforms in the London market. Most installations are dual-fuel pairings with existing gas furnaces, switching the heat pump off below -15°C where gas takes over. London permits are required for both mechanical and electrical work, with an Ontario-licensed mechanical contractor handling the install.
London's mix of older Old North and Old South homes plus newer suburbs drives diverse heat pump demand. Save On Energy rebates plus the federal Greener Homes program often reduce net install cost by 30-40% compared to historical pricing. Heat pumps handle 80-90% of annual heating hours efficiently with gas backup needed during the coldest 5-10 days. Enbridge Gas provides natural gas service throughout most of London making dual-fuel installations straightforward.
Frequently Asked Questions
- Will heat pumps work in London winters?
- Modern cold-climate heat pumps maintain rated capacity at -15°C (typical London design temps) and continue operating to -25°C or lower. Dual-fuel installations with gas backup handle the rare deeper cold snaps. Most London installations use this hybrid approach for reliability.
- What rebates apply?
- The federal Greener Homes grant covers up to $5,000 CAD plus interest-free loans up to $40,000 CAD. Save On Energy provides additional rebates depending on equipment ratings. Combined incentives typically reduce net cost by 30-40% versus historical pricing.
- Should I keep my gas furnace?
- Yes, dual-fuel installations are popular in London. The heat pump handles 80-90% of annual heating hours; the gas furnace covers the coldest 5-10 days. This delivers most of the heat pump's efficiency benefit while preserving Enbridge gas service for backup reliability.
