Is Your Furnace Blowing Cold Air? Here's Why.
During the cold winter months, it is essential that you have a furnace that is going to heat your home thoroughly. When your heater is blowing cold air, and there is a snowstorm outside, this will be quite stressful. When you have a furnace blowing cold air, the reason could be one of the following:
1. Your Thermostat May Need Service
We'll want to first, take a look at your thermostat since this is the main component of the temperature change. The issue of your furnace blowing cold air could be coming from your thermostat. There are times where you think that you are telling your furnace to blow warm air, but that is not the case. Instead of turning on the heat, your thermostat is just turning on the blower/fan. If it's already cold outside, your fan could be the cause of cold air flowing through your house. When you are looking to fix this problem, you will need to turn off your thermostat, turn it back on, and then leave it on the auto function. Turning on the fan and forgetting to flip on the heater is a common issue, whoops! Make sure it's on so you will finally have the warm air your home needs.
2. The Pilot Light Might Not Be Lighting Your Furnace
If you are having issues with your pilot light, you will not be able to get the flames going that will heat your furnace, thus your home. It is crucial that you check your pilot light right when you think there is cold air flowing through your home. If you are mechanically inclined, you can use your furnace's manual to get your pilot light lit again. However, there are some models of heaters that can be more difficult than most. If you're not having any luck, do not hesitate to reach out to us here at CHA.
3. Your Furnace May Have a Clogged Gas Line
Your furnace needs gas to function correctly. If you are not able to get enough gas to your furnace, you are going to end up just circulating cold air with your blowers. Clogged gas lines can be a dangerous thing to have. If you feel like you might have clogged gas lines in your home, you need to talk to a professional immediately. They will be able to assess the situation and take care of this danger as soon as possible.
4. You May Have Issues With Your Ducts
When you not getting warm air throughout your house, you could have some issues with your ducts. It is common for air ducts to get clogged with dust and other debris. If you have not had your ducts cleaned in a long period of time, it might be just what you need to get the warm air circulating again. However, you may have a more serious problem with older ducts that now have holes in them. Air leaks will let out the warm air in different places in your home.
