Furnace
Troubleshooting Guide

Heating and cooling systems can sometimes develop minor issues that affect their performance. Before scheduling a repair, there are a few simple troubleshooting steps homeowners can try. This guide from Alberta Heating Services can help you identify common HVAC problems and determine when it's time to call a professional technician.

Furnace Not Producing Heat

If your furnace isn't heating properly, try the following steps:

• Check that the thermostat is set to “heat” and the temperature is higher than the current room temperature.

• Ensure the furnace power switch is turned on.

• Check the circuit breaker to make sure it hasn't tripped.

• Inspect the air filter and replace it if it's dirty or clogged.

• If the furnace still doesn’t produce heat, it may require professional inspection.

Furnace Blowing Cold Air

If your furnace is running but blowing cold air:

• Make sure the thermostat is set correctly.

• Check if the pilot light or ignition system is working.

• Replace a dirty air filter, which can restrict airflow.

• Persistent issues may indicate problems with the burner or internal components.
