A sudden loss of heat during a Winnipeg winter is more than an inconvenience – it's an emergency. When your furnace fails, understanding the potential cause can help you decide the next steps.

We've compiled a list of common furnace problems to help you identify what might be wrong and know when it’s time to call in the experts for your heating and cooling in Winnipeg.
No Heat in Winnipeg? 6 Common Furnace Problems
No Heat in Winnipeg? 6 Common Furnace Problems
Clogged or Dirty Air Filters
A clogged filter is one of the most frequent causes of furnace failure. It restricts airflow, forcing the system to work harder to circulate air, which can lead to overheating and shutdown. We recommend checking your filter monthly and replacing it every 1-3 months to ensure optimal performance and prevent unnecessary strain on your HVAC system.
Thermostat Malfunctions
Sometimes the problem isn't the furnace itself but the thermostat that controls it. An incorrect setting, dead batteries, or faulty wiring can prevent it from signaling your furnace to turn on. Before assuming the worst, we suggest checking that your thermostat is set to "heat" and the temperature is high enough to trigger the system.
Pilot Light or Ignition Control Failure
If you have an older furnace, the pilot light may have gone out. For newer systems, a faulty electronic ignitor could be the culprit. These issues prevent the burners from lighting to heat the air. Due to the involvement of gas and electrical components, we advise that ignition-related problems are best left to a qualified technician.
Blower Motor Issues
The blower motor is responsible for pushing the warm air from your furnace through the ductwork and into your home. If you hear the furnace turn on but feel no air from the vents, the motor may have failed. Unusual noises like squealing or humming can also indicate a motor that is about to break down.
Cracked Heat Exchanger
This is a serious safety concern. The heat exchanger separates the combustion process from your breathing air, and a crack can leak dangerous carbon monoxide into your home. A tell-tale sign is a strange smell, similar to formaldehyde. If you suspect a crack, turn off your furnace immediately and call for emergency service.
Blocked Vents or Ductwork
Your furnace can't heat your home effectively if the air has nowhere to go. Ensure that all vents and registers throughout your house are open and unobstructed by furniture, rugs, or curtains. Obstructed airflow can cause pressure to build up within the system, leading to overheating and potential damage to internal components.
