Calgary HVAC Rebates & Incentives for 2026

Why Calgary Homeowners Should Act on HVAC Rebates in 2026

Government incentives for energy-efficient HVAC upgrades are more generous in 2026 than they have ever been. Between federal programs, provincial initiatives, and utility rebates, Calgary homeowners upgrading a furnace, heat pump, or air conditioner can access thousands of dollars in financial support. This guide covers every current program and how to claim them.

Canada Greener Homes Loan

The federal Canada Greener Homes Loan offers interest-free financing up to $40,000 for eligible home energy efficiency upgrades. This is not a grant — it is a loan you repay without interest — but it dramatically reduces the upfront barrier to upgrading.

Eligible upgrades include high-efficiency furnaces rated 96% AFUE or higher, heat pump installations, air sealing, insulation, and window and door replacements.

To qualify, you must complete a pre-retrofit EnerGuide home energy evaluation before starting work, and a post-retrofit evaluation after completion. The evaluations are performed by a registered energy advisor. Infills Mechanical can refer you to qualified advisors in Calgary.

Applications are submitted through Natural Resources Canada. Allow 4 to 6 weeks for processing.

Alberta Home Energy Retrofit Accelerator

The provincial Alberta Home Energy Retrofit Accelerator program offers up to $5,000 back on qualifying heat pump installations. This program specifically supports the transition from natural gas heating to electric heat pumps.

To qualify, the heat pump must meet minimum efficiency standards and be installed by a licensed contractor. Infills Mechanical is a licensed HVAC contractor in Alberta and can ensure your installation meets program requirements.

This rebate can be combined with federal programs, making heat pump upgrades particularly attractive in 2026.

Lennox Manufacturer Rebates

As a Lennox Premier Dealer, Infills Mechanical has exclusive access to seasonal manufacturer rebates. Current Lennox promotions offer up to $1,800 back on qualifying furnace and heat pump systems.

These rebates change throughout the year. Contact us directly to find out what is currently available and which equipment qualifies.

Enmax Energy Efficiency Rebates

Enmax, Calgary's primary electricity utility, periodically offers rebates on qualifying energy-efficient equipment. Current offerings include:

Smart thermostat rebates of $75 to $100 when you install a qualifying programmable or smart thermostat. Eligible models include the Lennox iComfort, Ecobee, and Honeywell T6 Pro series.

Check the Enmax website or contact us for current availability, as these programs have limited funding and can end without notice.

ATCO Gas Rebates

ATCO Gas, which supplies natural gas to most Calgary homes, offers rebates on high-efficiency furnaces and boilers. High-efficiency natural gas furnaces rated 95% AFUE or higher may qualify for rebates up to $200.

Contact ATCO or visit their website to confirm current rebate amounts and application requirements.

How to Stack Multiple Rebates

The best strategy is to combine available programs. A typical heat pump installation in Calgary in 2026 could qualify for:

The Canada Greener Homes Loan covering the full installation cost interest-free, the Alberta Retrofit Accelerator providing up to $5,000 cash back, and the Lennox manufacturer rebate of up to $1,800 — potentially reducing your effective net cost by $6,800 or more.

For furnace replacements, combining the federal loan with the ATCO rebate and a Lennox manufacturer promotion can reduce costs by $2,000 or more.
