During the winter, the last thing you want to have happen is a furnace issue. When your furnace isn’t working to heat your home, it can be an emergency if the weather is cold enough. When you turn on your heat and feel nothing but cold air coming from the vents in your house, it can be frustrating. There are several reasons why you might be experiencing this. Hal Mechanical is here to talk about some of the most common reasons you might be feeling cold air blowing from your vents.
Why are My Vents Blowing Cold Air when the Heat is On?
There are multiple reasons why you might be experiencing cold air coming from your vents even though your furnace is on, and you should be starting to feel the air warm up. Following are some of the most common reasons this might be happening:
– Thermostat: Make sure your thermostat is set to heat your home rather than cool or have the fan simply blowing. This is always the first thing that homeowners should check when they don’t feel comfortable in their home.
– Dirty Filter: The next thing that needs to be looked at is the filter. A dirty filter can absolutely be the cause of the cold air you’re feeling. If your furnace isn’t getting enough air circulation during operation, it won’t be able to work properly.
– Clogged Condensate Drain: There is some moisture that is a byproduct of your furnace running. This water usually just drains away with the help of the condensate drain. If the line is clogged, it can cause this water to build up and leak all over the place. It can lead to problems for your furnace as well.
– Pilot Light Not Lit: Some older furnaces have a pilot light that needs to stay lit all the time. Newer furnace have an ignition system that lights only when the furnace is getting ready to cycle through. If your pilot light isn’t lit on your older furnace, it could be the cause of the problem.
– Malfunctioning Flame Sensor: Furnaces have a safety sensor that will detect the presence of a flame. This is important so that natural gas doesn’t build up inside the furnace for any reason. Over time, that flame sensor can get grimy and dirty which causes it to malfunction. If you are feeling cold air, make sure the flame sensor is clean.
– Cracked Heat Exchanger: A cracked heat exchanger is one of the most serious problems that you can have in your furnace. It allows carbon monoxide to leak into the air you’re breathing. This can be dangerous for anyone in the house and even lead to death if it isn’t caught soon enough.
