About our furnace repair service

When your furnace quits in the middle of a Simcoe County cold snap, waiting isn't an option. Our TSSA-certified gas technicians diagnose and repair every major residential furnace brand, Carrier, Lennox, Trane, Goodman, Amana, Rheem, and York, with fully stocked trucks and honest, flat-rate pricing. We also handle emergency furnace repair after hours, weekends, and holidays.

No-heat calls cluster in predictable places here. The Alcona subdivisions built between 2006 and 2012 are now on their second decade of builder-grade single-stage furnaces, and the failures we see most are cracked igniters and flame sensors fouled by twelve years of one-inch filters. In the older Churchill and Stroud bungalows it is more often a pressure switch tripping on a partially blocked side-wall vent after a wind-driven snow squall. Out toward Ivy and Utopia in Essa, farm dust is the culprit and the fix starts at the filter cabinet, not the board.

Where we provide furnace repair

Innisfil is home base, and our trucks run the same routes daily across Simcoe County and north York Region.

  • Barrie In Barrie the calls concentrate in the south end, where Painswick, Ardagh and Holly subdivisions are running the original builder furnaces past their fifteenth winter.
  • Bradford West Gwillimbury Bradford and Bond Head homes back onto the Holland Marsh, and the damp cold there is unforgiving on a system that was never balanced for the ductwork it feeds.
  • Essa Angus, Baxter and the CFB Borden housing sit on open ground where wind-driven snow buries side-wall vents, which is the single most common cause of a no-heat lockout out there.
  • East Gwillimbury Holland Landing, Sharon and Queensville have grown fast, so most of what we service there is newer high-efficiency equipment needing commissioning corrections rather than replacement.
  • Springwater Midhurst, Elmvale and the Snow Valley custom builds are in the snowbelt, where a heating system has to hold a design temperature several degrees colder than Barrie's.
  • Newmarket Newmarket's older Gorham and Glenway neighbourhoods still hold plenty of mid-efficiency equipment that is cheaper to replace than to keep feeding gas.
  • Oro-Medonte Many Oro-Medonte and Horseshoe Valley properties are off the gas main entirely, so heating decisions there weigh propane cost against a heat pump conversion.
  • New Tecumseth Alliston, Beeton and Tottenham see steady demand around the Honda plant shift schedule, and we book those calls early morning or evening to suit it.
