Q: What Are the Best Heated Garage Options for Calgary Winters?

Calgary winters demand reliable garage heating. The best options are in-floor radiant heating (most comfortable, $8,000–$15,000), forced-air systems ($5,000–$10,000), and mini-split heat pumps ($6,000–$12,000). Radiant heating works best for new builds or major renovations. Mini-splits offer flexibility and lower upfront costs. All systems require Alberta Building Code compliance and City of Calgary permits. Insulation is critical—upgrade walls and doors first to maximize efficiency and reduce operating costs.

Cost Breakdown (Calgary 2024)

System	Installation	Annual Operating	Lifespan
In-Floor Radiant	$8,000–$15,000	$600–$900	25+ years
Forced-Air	$5,000–$10,000	$800–$1,200	15–20 years
Mini-Split	$6,000–$12,000	$500–$800	15–20 years

Permits and Building Code

The City of Calgary requires permits for any heating system installation. Your contractor must comply with Alberta Building Code Section 9.23 (garages) and ensure:

Proper ventilation (ASHRAE 62.2 standards)
Carbon monoxide safety if using gas
Electrical work by licensed Red Seal electrician
Inspection before final approval

Maximize Efficiency

Heating alone won’t solve winter comfort. Prioritize:

Insulate walls to R-20 minimum
Upgrade garage door (R-16 or higher)
Seal air leaks around frames and foundations
Install proper ventilation

A well-insulated garage with a mini-split system often outperforms a poorly insulated space with radiant heat.
