4 Things to Look for When Your Furnace Is Blowing Cold Air This Winter

snuggly

If your furnace is blowing cold air, do you need professional furnace repair? Possibly. If your HVAC system is blowing, but only blowing cold air, you can troubleshoot before calling for repair. Here are four things to check:

1. Look at the Pilot Light

Sometimes the pilot light of your furnace can go out, which will prevent it from working. If the pilot light is out, check your furnace manual for instructions on how to re-light it. If the pilot light is still lit but the furnace still isn't blowing hot air, there could be a problem with the furnace itself.

2. Change Your Air Filter

You should change your air filters once every few months. If you have pets, you should be replacing it more frequently—sometimes as often as once a month. If you haven't changed the filter in a while, a dirty filter may be preventing the air from circulating properly. Or, though the air may be hot when it comes out of your furnace, it may have cooled by the time it gets circulated.

3. Test Your Thermostat

It's possible your thermostat may be set too low, especially if you've been using your cooling system up until now. Also, make sure the thermostat is set to heat and that the reading on the thermostat matches up with the indoor temperature. Sometimes a thermostat may be reporting warmer temperatures because it’s next to something hot, like a sunny window or a lamp.

If you can't figure out what's wrong, it's time for professional furnace repair. For furnace repair you can count on, contact our friendly, reliable experts at Dependable Service Plumbing & Air.
