Brrr! The air is turning cold, and that can only mean one sign: winter season on its way and furnace season is upon us. Turning on the furnace in your home can be one of the most satisfying things you can do on a cold day. But what happens when your trusty heating & furnace system needs repair and blows cold air instead of cozy warmth? That’s a sign that there’s something seriously wrong with your furnace, don’t panic! Before you call the expert Edmonton’s plumbing or HVAC service provider, find out these 4 common furnace issues you can troubleshoot yourself easily by keeping these important things in mind.

1) Start with the thermostat

If you have a modern thermostat, then you need to get to know its multiple settings. Confirm that the system is set to ‘heat’ and verify the actual temperature. After resetting it, wait a few minutes for the system to adjust to the new settings. If the heater still blows cold air, the thermostat may need to be recalibrated or replaced.

2) Troubleshooting a gas furnace

If your gas furnace doesn’t turn on, check the circuit breaker. If the breaker is tripped, the electronic starter will not have power, and consequently, won’t be able to ignite the burner, and a cold air-blowing heater is what you get. If you have an older model. Check that the pilot light is on, and that the gas supply line valve is open.

3) Troubleshooting an electric furnace

As with your gas furnace, start with the circuit breaker and verify that it has not tripped. Reset it if it has. If the breaker trips again after you reset it, that’s a sign of a short circuit within the furnace system or some other malfunction. If your heating elements are overworked or burned out due to a short circuit, the system will blow cold air. Have an Edmonton furnace repair professional locate and solve the problem.

4) Troubleshooting a heat pump

Heat pumps use auxiliary heat strips if the exterior temperature is overly cold. If there’s a problem with these heat strips, the heat pump will blow cold air. During the summer, if the refrigerant level is low, the pump won’t be able to transfer heat efficiently. Have a professional inspect the heat strips and refrigerant level.


Don’t suffer through a cold house! If your furnace is blowing cold air, these troubleshooting tips can help you identify and potentially fix the problem. But remember, for complex issues or safety concerns, always consult a qualified Edmonton furnace repair professional. Stay warm!
