In the middle of an Erie, PA, winter, the last thing you want is for your furnace to begin blowing cold air. Fortunately, if you do experience this problem, there are a few things that you can check that will hopefully get your furnace back up and running. To help you properly diagnose your furnace, here are a few tips from J.J. Agnello Heating & Air Conditioning Inc.

Thermostat Not Working

If your furnace is blowing cold air, don’t panic. Sometimes, the cause could be as simple as a faulty thermostat. Even if the screen on your thermostat is working, your thermostat may have low batteries or a bad connection to the furnace. If replacing the batteries doesn’t help, give J.J. Agnello Heating & Air Conditioning Inc a call so that we can take a look.

Dirty Air Filter

Do you know the last time you changed your air filter? If not, that could be the cause of your furnace troubles. A dirty air filter will significantly reduce the amount of air that can flow through your system. This will cause the heat exchanger to increase in temperature to the point that your furnace shuts off the burner to protect the heat exchanger. It’s a good idea to check your filter at least once a month.

Cracked Heat Exchanger

Even if you take good care of your furnace, you may experience a cracked heat exchanger. The heat exchanger transfers the heat produced by the burner to the unconditioned air as it moves through your system. A cracked heat exchanger will require the assistance of J.J. Agnello Heating & Air Conditioning Inc to diagnose and repair.
