Why Is My Heating System Blowing Cold Air?

A furnace that kicks out cold air isn’t going to do a lot for you during the year’s colder months. If you are noticing that your furnace is blowing out cold air, and therefore not warming the home, then it’s time to get to the bottom of it right away.

This doesn’t necessarily mean that your furnace is dead. The staff at W A Air Conditioning in Trinity, Texas, can help you pinpoint the problem. Truthfully, you might even be able to diagnose the problem on your own by checking on these four components of your heating system:

1. Thermostat

You may have your thermostat set to the “On” setting, which means that whether or not your furnace is on, the fan is going to keep circulating air throughout your home. By switching it to the “Auto” setting, you can make sure it’s only running when your furnace is producing warm air.

2. Pilot Light

If your burners are filthy or a draft of air invades your furnace, your pilot light could go out. This means that your burners will not ignite when your furnace is running, so it’s left to blow out cold air only. You can relight the pilot but take all necessary precautions to avoid hurting yourself.

3. Air Filter

Only in extreme situations will your furnace’s air filter stop warm air from circulating through your home. If an air filter has gone unnoticed for a long period of time, it might be so caked with dust, dander, dirt and other debris that it stops the flow of air from your furnace to your air ducts.

4. Fuel Supply

If your home runs on natural gas, you won’t have to worry about this one. However, if you draw from a propane or oil storage tank, check to make sure the tank hasn’t run out. With no fuel, there will be no fire for your furnace.
