Oakville grew in waves, and each wave left a different kind of furnace in the basement.

A few checks take two minutes and sometimes solve it.
| What you see | Check this first | Call us if |
|---|---|---|
| No heat at all | Thermostat on Heat with fresh batteries, the furnace switch on, the breaker on | Everything is on and there is still no heat |
| Cold air from the vents | Fan set to Auto, not On, and a filter that is not clogged | The air is still cold after 10 minutes |
| Runs a few minutes, then stops | Put in a fresh filter | It keeps stopping with a clean filter |
| Water on the floor by the furnace | The drain hose is not kinked or frozen | The water keeps coming back |
| A light flashing inside the furnace | Count the flashes through the small window | Always. The code tells us which part to bring |
| A smell of gas | Do not touch any switches. Leave and call Enbridge at 1-866-763-5427 | Once Enbridge says it is safe, for the repair |
On a very cold night, a high efficiency furnace can stop because snow or frost is blocking its white plastic pipes outside. Clear them gently by hand, then set the thermostat again. Smell gas instead? See gas leak detection.
Same order every time, so you always know what comes next.

We run the furnace through a start and see the exact step where it fails.

We replace or clean the part, then run a full heating cycle and check the flame, the venting and the gas connections.
Gas valve or gas pipe work is done by our own licensed gas fitter, never another company.

It can be. Those pipes bring in air and push out exhaust for a high efficiency furnace. If snow or frost blocks them, the furnace shuts off to stay safe. Clear them gently by hand. If it still will not run, call us.
Check your builder warranty first. Some cover the furnace for the first years. If yours does not, or it has run out, we can repair it.
Yes. Most furnaces have a small light on the control board that you can see through a window in the lower door. Count the flashes and tell us the number. It points to the part, so we bring the right one.
Sometimes. A small part on a furnace that is otherwise sound can be worth fixing. A big repair on a 20 year old furnace usually is not. We give you both prices and you decide.
Yes. Our own licensed gas fitter does gas valve and gas pipe work. We do not hand gas work to another company. See gas line repair.
