    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.

    Our furnace went out during a cold snap and they were here within hours. Professional, friendly, and had us back up and running in no time. If you want it done right the first time, call these guys.

    Air Force Heating is great to work with, I’ve hired them on several occasions and always happy with their great service and expertise. Mike showed up on time, was super friendly and got the report back to us quickly. Looking forward to working with them again.

    Why Replace Now Instead of Next Year

    A new high-efficiency furnace pays back faster than most homeowners expect once you factor in rebates, financing, and the gas savings.

    Lower Energy Bills

    A modern 96–98% AFUE furnace burns far less gas than a 20-year-old 80% unit. Most homes see a 20–30% drop in winter heating costs.

    Cleaner, Quieter Heat

    Variable-speed blowers and two-stage burners deliver even temperatures, fewer cold spots, and noticeably quieter operation.

    10-Year Manufacturer Warranty

    New installs from Lennox, Carrier, and Trane include 10-year parts coverage. We back the labour for the first year.
