Furnace & AC help · Toronto & the GTA
Tap what you're dealing with. You'll see the usual cause, a price range and the fastest way to get it fixed.
No heat
First, check the thermostat is set to Heat and the furnace switch is on. Still cold? It's usually an igniter, flame sensor or pressure switch, and most of those are fixed in one visit.
AC not cooling
A tripped breaker, a failed capacitor, a dirty outdoor coil or low refrigerant cause most of these calls. We test all four before we quote you anything.
Strange noise
A new noise means a part is loose or wearing out. Switching the system off early often turns a big repair into a small one.
Thermostat issue
Try fresh batteries first. If that doesn't do it, we check the wiring, the C-wire and the settings, and set up smart thermostats so they actually save you money.
Maintenance
We clean, test and adjust the whole system and flag anything that's wearing out. Plan members get a spring AC visit and a fall furnace visit.
