Reasons Your Furnace Is Blowing Cool Air
Here are some of the most common reasons your furnace is blowing cold air inside the house.
Your thermostat is the first thing you should check if your furnace is blowing cold air. This is the central controller that sends signals to your furnace to turn on and off, depending on the surrounding temperatures. Make sure that you’ve set your thermostat correctly. It has to have a higher temperature setting than the setting in the room so that it works properly. There is a chance that your thermostat might be malfunctioning and needs to be replaced.
Another reason your furnace could be blowing cool air is that you have major leaks in the duct network throughout the home. If there is a significant leak, the hot air produced by the furnace could be blowing out of the torn part and letting cool air inside.
The pilot light could be out
A problem with some gas furnaces is the pilot light going out. This pilot light is a small flame that constantly keeps burning. When the thermostat sends the signal to your furnace to begin heating, it turns on the gas supply that is ignited by the pilot light.
Sometimes the pilot light can go out if the natural gas line to your home stopped due to maintenance work. If this is the case, you can simply light it up again and check if your furnace works properly.
Air filter problems
Clogged air filters can also result in the furnace blowing cold air. The air filter is there to make sure that no contaminants get into the heating system, and it ensures that everything runs smoothly.
If you do not change the air filter frequently, it can become clogged, and your furnace does not get to heat and distribute air throughout the house properly. Keeping the filter in your furnace fresh is, without a doubt, the most effective way in which you can contribute to its success. It’s simple, and it’s cheap!
