How a Furnace Works
- Return air — pulled in through the filter
- Blower — pushes air across the heat exchanger
- Burners — ignite to heat the exchanger
- Heat exchanger — transfers heat without mixing combustion gases
- Supply air — warm air delivered to the home
Furnace Repair for Scarborough Homes
Common furnace problems include no heat, blower issues, ignition failures, strange noises, short-cycling, and thermostat malfunctions. Our technicians can quickly identify the root cause and get your heat back on.
What Your Furnace Symptoms Usually Mean
Blowing cold air usually points to an ignition failure, a flame sensor coated in oxide, or a limit switch tripping on overheat — often from something as simple as a clogged filter choking airflow. Short-cycling (starting and stopping every few minutes) is commonly a dirty filter, a failing flame sensor, or an oversized furnace. Squealing suggests a blower belt or motor bearing; scraping metal means shut it down and call. A furnace that runs but keeps tripping its safety is doing its job — the safety is telling you something, and bypassing it is how CO accidents happen. Oil furnaces add their own patterns: a reset button that keeps tripping points to fuel delivery or ignition trouble, and pressing it more than once can flood the combustion chamber with unburned oil. One press, then call us.

When is a furnace not worth repairing?

A cracked heat exchanger on an older furnace is almost always a replacement, for safety reasons.
