Is there a City of Calgary rebate for upgrading to energy efficient windows or doors in 2026?

The City of Calgary does not offer direct rebates for window and door upgrades, but significant federal and provincial rebates are available for Calgary homeowners in 2026.

The Canada Greener Homes Grant provides up to $5,000 in rebates for energy-efficient home upgrades, including windows and doors. This federal program covers up to $250 per window (maximum 20 windows) and up to $250 per exterior door (maximum 4 doors) when you upgrade to ENERGY STAR certified products. To qualify, you'll need pre- and post-renovation EnerGuide home evaluations, which cost around $400-600 each but are partially rebated through the program.

Alberta's energy efficiency programs have evolved significantly, and while Energy Efficiency Alberta wound down many residential programs, the federal Canada Greener Homes Grant remains the primary rebate source for windows and doors. Some utility companies like ENMAX occasionally offer energy efficiency incentives, though these change frequently and are typically focused on heating systems rather than building envelope improvements.

Calgary's climate makes window and door upgrades particularly valuable due to extreme temperature swings from chinooks and winter lows reaching -30°C or colder. High-performance windows (triple-pane with low-E coatings) and insulated exterior doors can dramatically reduce heating costs and improve comfort. Look for products with low U-values (heat transfer) and high R-values (insulation) - triple-pane windows typically achieve U-values of 0.20 or lower, compared to 0.35+ for standard double-pane units.

Professional installation is crucial in Calgary's challenging climate. Improper installation can lead to air leaks, condensation issues, and reduced performance. Licensed contractors will ensure proper flashing, weatherproofing, and integration with your home's air barrier system. Window and door replacement typically requires building permits in Calgary, especially for changes to opening sizes or structural modifications.

The investment typically pays for itself through energy savings over 10-15 years, while significantly improving comfort and home value.
