Frequently Asked Questions

What is a cold-climate heat pump?

A cold-climate heat pump (CCHP) extracts heat from outdoor air down to -25 degrees Celsius or lower. Modern units maintain efficiency in Ontario winters and can replace both a furnace and central AC in a single system. Ontario rebate programs cover qualifying cold-climate heat pumps - see /rebates for current programs.

Is a dual-fuel system worth it in Ontario?

A dual-fuel system pairs a heat pump with a gas furnace backup. The heat pump handles mild Ontario weather efficiently; the gas furnace takes over when temperatures drop below the heat pump's cost-effective range. Dual-fuel can be a good fit for homes with existing gas infrastructure in colder rural Ontario locations.

What HVAC rebates are available in Ontario in 2026?

The Ontario Home Renovation Savings Program (HRSP) offers up to $7,500 for qualifying cold-climate heat pump retrofits in homes heated with electricity, oil, propane or wood (up to $2,000 for Enbridge gas-heated homes). The Canada Greener Homes Loan is closed - NRCan says new loan applications cannot be approved. Enbridge gas-heated homes can get up to $2,000 for a cold-climate air-source heat pump through Home Renovation Savings (the older HER+ program is closed). See /rebates for current program details.

How much does heat pump installation cost in Ontario?

A cold-climate heat pump installation in Ontario typically runs $5,000-$15,000 for supply and installation. System size, existing ductwork condition, and whether a full retrofit or add-on system is needed affects cost. Available Home Renovation Savings rebates (up to $7,500 for homes heated with electricity, oil, propane or wood; up to $2,000 for Enbridge gas-heated homes) can meaningfully reduce the net cost.

When is the best time to install or replace an HVAC system in Ontario?

Spring (April-May) and fall (September-October) are the best times for HVAC work in Ontario. Demand is lower than in peak summer or deep winter, and crews have more scheduling flexibility. If your system fails in summer or winter, emergency replacements are available, but expect premium pricing and tighter timelines.

What should I ask an HVAC contractor before hiring them in Ontario?

Ask whether they pull permits for the installation, whether they perform a Manual J load calculation (required to size equipment correctly), how they handle rebate paperwork, and what equipment warranty and labour warranty they provide. A proper load calculation prevents undersized or oversized systems that waste energy.
