Heater Repair Richmond HillNo Heat? Let's Find Out Why.
A furnace that will not start, short-cycles or blows cold air is almost always a diagnosis problem before it is a parts problem.
Furnace Repair
Won't start, short-cycles, or blows cold air? We find the actual cause — ignition, sensors, blower, airflow — and explain it in plain language before any work goes ahead.
Why it matters
- Most winter breakdowns start small: a dirty flame sensor, a clogged filter, a worn part working harder than it should.
- Caught early, those are quick fixes.
- Ignored, they become no-heat calls on the coldest night in January.
Helpful to know
- Check the filter monthly during heating season — a clogged filter is one of the most common causes of weak heat and short-cycling.
- Before assuming the worst, check the thermostat batteries, the furnace power switch and the breaker.
- Note what the furnace is doing — short-cycling, cold air, a new noise — and when it started. That pattern speeds up the diagnosis.
- If you smell gas or a carbon-monoxide alarm sounds, leave the house first and call your gas utility — before calling anyone else.

Common Questions
How quickly can you get here for a no-heat call?
During business hours we prioritise no-heat situations and get to them as fast as we honestly can. CopperCraft does not run a 24/7 service, so an overnight message is answered the next working day rather than at 3 a.m.
Will you tell me if the furnace is not worth repairing?
Yes. If the equipment is old enough that parts are scarce, or the repair costs a meaningful fraction of a replacement, we will say so and lay out both options. The decision stays yours.
Is a strange smell when the heat first comes on normal?
Dust burning off the heat exchanger at the start of the season is common and passes within an hour or so. A persistent burning, electrical or sulphur smell is not, and a gas smell means leaving the house and calling your gas utility first.
