    Air Force Heating did an excellent job removing our old hot water tank and installing a new Navien tankless water heater at a very competitive price !! The technicians were professional, knowledgeable, and completed the installation efficiently. They took the time to answer my questions, cleaned up after the job, and made sure everything was working properly before leaving. Very happy with the quality of work and the improved hot water system. I would definitely recommend Air Force Heating to anyone considering a tankless water heater upgrade.

    Excellent experience with Ivan and his team, install on my AC unit was fast, like 4 hours! Guys were clean and courteous. I would 10/10 recommend them and use them for their other HVAC services!

    The process was top notch through the whole process: 1) They answered the request for a quote quickly (I'm surprised when other companies called back 3-4 days later). They came the next day at the agreed upon time. 2) The quote was reasonable and about $50 less than others (tight market). 3) The installation was scheduled quickly, and done well the following week. 4) It appears as if the work was done professionally with an attention to detail. It's still too cold to see how everything works, but will update the review as needed. 4) Communication was prompt and helpful. I would recommend Ivan and Air Force Heating in the future.

    We needed a new Air Conditioner. An appointment was promptly scheduled with Mike. For the installation, we received great service from Ivan and Dmytro for our new Armstrong A/C. All our questions were answered and they did a great job.

    Had a really good experience with Air Force Heating and Air Conditioning. They installed a Gree heat pump for me and everything went smooth. Showed up on time, explained things in a simple way, no pressure or upselling. Install was clean and pretty quick, and the system is working great so far. Only thing is I wish they walked me through the thermostat a bit more, but overall still very satisfied. Would recommend.

    Good experience with Air Force Heating and Air Conditioning overall. Had a Gree heat pump installed and Ivan, Dima and Rustam did the job. They showed up on time, were polite, and kept things clean during install. System is working good and you can feel the difference already. Only small thing is I had to ask a couple questions after they left to understand all the settings, but not a big deal. Solid service, would recommend.

    I just had an air conditioning unit installed at home, and I couldn’t be more thrilled! The team was fantastic—super efficient and committed to quality at every step. What really impressed me was their honesty; they communicated everything clearly and set realistic expectations. I highly recommend them for anyone looking to enhance their comfort!

    Calgary Garage Heater Sizing Guide

    Right-sizing matters more than brand. An undersized heater never catches up on a cold morning; an oversized one short-cycles and wastes gas. Use this as a starting point — we confirm the exact BTU on site.

    • Single garage (350–450 sq ft): 30,000–45,000 BTU
    • Standard double garage (450–600 sq ft): 45,000–60,000 BTU
    • Triple garage or 9 ft ceilings (700–900 sq ft): 60,000–75,000 BTU
    • Heated workshop (900–1,200 sq ft): 75,000–100,000 BTU
    • Insulated shop (1,500+ sq ft): 100,000–150,000 BTU
    • Uninsulated detached garage: add ~25% to recommended BTU
    • Tall ceiling (12 ft+): add ~15% to recommended BTU
    • Concrete-floor cold-soak: add a programmable setback thermostat

    How a Permitted Garage Heater Install Works

    A garage heater is a gas appliance — installation has to be done right or the manufacturer warranty (and your home insurance) is void. Here's the proper sequence.

    Heat-Load Sizing

    We measure square footage, ceiling height, and insulation, then run a Manual J style calculation so the unit isn't oversized or undersized for your space.

    Gas, Vent & Electrical

    Our licensed Alberta gas fitters run new lines, set venting clearances, and connect the thermostat — pulling permits where the city requires them.

    Commissioning & Walkthrough

    We test combustion, set the thermostat to your usage pattern, and walk you through filter changes, seasonal shut-down, and warranty registration.
