Furnace and air conditioning service in Smithville

Check that the thermostat is on heat and set above the room temperature, that the filter is not clogged, and that the furnace power switch is on. Do not open the burner area or touch the gas valve. Work is performed by TSSA-certified gas technicians, and in Ontario only certified gas technicians may service a gas furnace. If the basic checks do not bring the heat back, book a furnace repair visit.

It depends on what has failed and whether the part is on hand. Common faults such as a dirty flame sensor, a failed igniter or a pressure switch are often fixed on the first visit. Larger parts, such as a control board, inducer motor or blower motor, may need to be ordered for your model, and the technician will explain what can be done in the meantime. A cracked heat exchanger is different: the furnace is shut off and stays off until it is dealt with, because it can leak carbon monoxide into the house. See furnace repair.

Check that the thermostat is set to cool, replace the filter and make sure the outdoor unit is clear of grass, leaves and anything stacked against it. Check the breaker once, but if it trips again, leave it off, because repeated tripping points to an electrical or compressor problem. Ice on the indoor coil or the copper line means turn the system off and let it thaw. Work is performed by 313A refrigeration and air conditioning mechanics, who handle refrigerant leaks and electrical faults. See air conditioner repair.
