When your furnace blows cold air, it’s time for service. Winters are too cold to go without heat. Ignoring the issue can leave you uncomfortable and lead to bigger problems. Luckily, we offer furnace service in St. Paul and the surrounding areas, and we’re here to help.
There are a few common reasons why your furnace might blow cold air instead of heat. Some issues are minor and easy to fix, but others need professional attention. Let’s take a look at what could be causing the problem.
Common Reasons Your Furnace Is Blowing Cold Air
First, check your thermostat. It’s surprising how often the thermostat causes furnace issues. It could be set to “cool” instead of “heat.” If that’s the case, switch it to “heat” and you should be good to go. But if you’ve already tried that and the air is still cold, dead batteries or faulty wiring in the thermostat could be the problem.
Another common issue is with the ignition or pilot light. For gas furnaces, the pilot light must be lit for the furnace to produce heat. If the ignition system is broken, the furnace will blow cold air.
Dirty air filters are another culprit. When filters are clogged, airflow is restricted, which can cause cold air to blow through your vents. Changing your air filters regularly is an easy way to avoid this problem. Annual furnace maintenance is a great way to catch this early.
Lastly, more significant mechanical problems like a broken blower motor or a faulty heat exchanger could also be the reason your furnace is blowing cold air. In these cases, professional service is your best bet.
