    Installers were efficient, clean and on time. No surprises! Only one little surprise when they found our AC (already installed) was leaking. We would of never known if it wasn't for them. They took the time to repair it right away. Much appreciated!

    A level above the rest! Ivan and his crew did a fantastic job moving our A/C unit and installing a heating system in our garage. They were completely on time, on budget, and very reasonably priced. What really stood out was the great respect they showed for our home and yard. They used drop cloths inside and tarps outside, taking extra care to minimize the mess and clean up after themselves completely. We’ve used other Plumbing & HVAC contractors in the past who were just okay, but Air Force's service quality was a level above all of them. Highly recommend!

    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.
