How much does a garage heater cost to install?

Garage heater installation in Calgary typically ranges from $2,500 to $5,000+ depending on the heater size (BTU output), gas line requirements, venting, and electrical work needed. We provide free on-site estimates to give you an accurate quote.

What size garage heater do I need?

The right size depends on your garage's square footage, ceiling height, insulation level, and desired temperature. As a general guide: a 2-car garage typically needs 45,000-75,000 BTU. Our technicians perform a heat load calculation to recommend the perfect size.

Are garage heaters safe?

Yes, when professionally installed. Modern Reznor unit heaters include safety features like flame sensors, overheat protection, and sealed combustion options. Professional installation ensures proper venting, gas connections, and clearances for safe operation.

How much does it cost to run a garage heater?

Running costs depend on the heater size, natural gas prices, and how often you use it. A typical 75,000 BTU heater costs roughly $1-2 per hour to operate with natural gas. Many homeowners use a thermostat to maintain a minimum temperature and reduce costs.

Can you install a garage heater in any garage?

Most garages can accommodate a unit heater, but some may need gas line installation, electrical upgrades, or venting modifications. Separated combustion models work well in tighter spaces. We assess your garage during the free consultation.

Air Force was so good to deal with. Ivan, Dima and the crew did such a clean job installing our Furnace, AC and hot water tank. They were fast and easy to deal with, and did a spectacular job installing everything. Would definitely recommend them to anyone.

I had an exceptional experience with Air Force Heatng and Air Conditioning Inc.! From start to finish, their service was top-notch. The technicians were punctual, courteous, and highly skilled. They installed my furnace and AC, leaving them in pristine condition. I was impressed by their attention to detail and professionalism. They provided valuable tips for maximizing efficiency. I highly recommend this company for anyone in need of a their services. Their outstanding work and friendly approach make them stand out from the rest! Dec 30, 2025 I had an excellent experience with Air Force Services. Two technicians came to my home to replace the hot water tank, and they did a fantastic job. They were fast, professional, and very polite, and they took the time to clearly explain everything they were doing and answer my questions. This is the second time I’ve hired Air Force Services, and once again the service was extremely efficient and reliable. I really appreciate their professionalism and quality work, and I would absolutely recommend them.

Airforce and its owner, Ivan, are excellent, they installed 2 gas heaters for my garages, 1st one in September 2023, 2nd one just 2 weeks ago! Ivan is professional, always prepared well before he came, arranged things and people in details as gas heating can be so important and also can be dangerous! Ivan, his company have done good jobs for me 2 times, the gas heater served me very well in 1st garage, actually installed gas heater in that garage helped me in a way have sold the house in September this year! The 2nd heater working in my brand new garage is so far so good! I would recommend Ivan, his company to my family, my friends, and to all! They are good, not easy to find them any more in Calgary from my experience.
