What Caledonia Furnace does in Oakville
Oakville homeowners can book Caledonia Furnace for furnace repair, furnace replacement, air conditioning, heat pumps and seasonal maintenance. The technician treats the furnace, the venting and the ductwork as one system, because a fault in one usually shows up in another.
Air conditioning, central or ductless
Central air needs ducts large enough to carry cool air. When the ducts are small or were added to an older house after the fact, a ductless system with indoor heads in the main rooms often cools better than forcing more air through the old runs. Air conditioning installation starts with a look at the ductwork before any size is chosen. Work is performed by 313A refrigeration and air conditioning mechanics.
Furnace faults and replacements
Common furnace calls include:
- No heat, or a furnace that lights and then shuts off.
- Water pooling under the unit from a blocked condensate drain.
- Loud banging on start-up, or a blower that runs without stopping.
See furnace repair for those. If replacement makes more sense, the new furnace is matched to the house and its ducts, and the venting is checked, including any water heater that would be left alone in an old chimney. Details are on the furnace replacement page. Work is performed by TSSA-certified gas technicians.

Learn moreQuestions from Oakville homeowners
My Oakville house has small ducts. Can it still have air conditioning?
Often, yes. Small or retrofitted ducts struggle to move enough cool air for central air, and the system ends up noisy and uneven. A ductless system puts indoor heads in the rooms that need them and skips the ducts. The technician measures the ductwork first and tells you which option fits. Work is performed by 313A refrigeration and air conditioning mechanics. See air conditioning installation or ask for a written quote.
Why won't my furnace come on when the thermostat calls for heat?
Start with the simple things. Is the thermostat set to heat and above room temperature, with fresh batteries? Is the furnace service switch on, and the breaker on? Is the blower door panel fully closed? On a high-efficiency furnace, are the side-wall pipes clear? You can reset the furnace once by switching it off and back on. If it locks out again, stop resetting it, because repeated lockouts point to a real fault. The common furnace problems guide lists what to check.
Why is my furnace blowing cold air?
First check the thermostat fan setting. On ON, the blower runs between heating cycles and moves cool air. Set it to AUTO. If the air stays cold during a call for heat, the burners have probably stopped. A clogged filter can overheat the furnace and trip the limit switch. A dirty flame sensor shuts the burners off seconds after they light. On high-efficiency units, a blocked condensate drain trips a pressure switch. Change the filter, then book a furnace repair if the cold air continues.
