What is the average cost of garage heater install in Calgary in 2026?

Installing a garage heater in Calgary typically ranges from $800-$3,500 depending on the type of heater and complexity of the installation. For a basic electric unit heater, expect $800-$1,500, while a gas-fired unit heater runs $1,500-$3,500 including permits and professional installation.

Electric garage heaters are the most straightforward option for Calgary homeowners. A 240V electric unit heater (5,000-7,500 watts) suitable for a standard two-car garage costs $300-$600 for the unit, plus $500-$900 for electrical installation. You'll need a dedicated 240V circuit run from your electrical panel, which requires an electrical permit from the City of Calgary and inspection by a licensed electrician. Total project cost typically falls between $800-$1,500.

Gas-fired unit heaters are more popular in Calgary due to Alberta's relatively low natural gas prices and harsh winters. A 30,000-60,000 BTU gas unit heater costs $600-$1,200 for the equipment, but installation is more complex. You'll need gas line installation, venting through the roof or wall, electrical connection for the fan and controls, plus both gas and electrical permits. Professional installation typically adds $900-$2,300, bringing total costs to $1,500-$3,500.

Calgary's extreme winter conditions make proper sizing critical. Your garage heater needs to handle temperatures down to -30°C or colder, plus account for heat loss through uninsulated garage doors and walls. Most Calgary garages need 30,000-60,000 BTU for gas units or 5,000-7,500 watts for electric. Factors affecting your cost include distance from your electrical panel or gas meter, whether you need new electrical circuits or gas lines, venting requirements, and the age of your home's electrical system.

Permits and safety requirements are non-negotiable in Calgary. Gas work requires a licensed gas fitter and inspection by a Safety Codes Officer. Electrical work needs a licensed electrician and electrical permit from the City of Calgary. Attempting DIY installation on gas or high-voltage electrical is illegal and dangerous. All contractors must carry WCB Alberta coverage and proper licensing.

Your next steps should be getting quotes from licensed HVAC contractors who can assess your garage size, insulation, and existing utilities. They'll help you choose between electric and gas based on your usage patterns and utility costs.
