Reasons Your Furnace Is Blowing Cold Air
When your home or office furnace is blowing cold air instead of warm, you likely have a problem with ductwork, filter clogging, or a clogged chimney. This blog will explain these issues and more.
1. The Pilot Light Is Damaged
The most common problems with a furnace are a failed pilot light or a dirty flame sensor. If your pilot light isn’t working, the air won’t get heated. The blower fan will still be running, though. So, there will be cold air coming from your vents. If the flame sensor needs to be cleaned, it won’t light the pilot when it is supposed to, and you will get cold air instead of hot coming out of your vents. Scheduling regular maintenance with one of our professional technicians will help prevent this issue from happening.
2. Your Ductwork Is Clogged or Leaking Air
If you have an older furnace that blows cold air, it could signify a clogged or disconnected return duct. You should have your ductwork inspected and cleaned. If the system is more than a decade old, it may need to be replaced. A professional can help you determine what needs to be done.
3. Your Furnace Filters are Blocking the Air
As your furnace runs, the filter becomes clogged with dust, debris, and other things floating around in the air. If you do not replace your air filters on a regular basis, it can restrict the airflow. Restricted airflow can cause your system to overheat, which can result in cold air coming from your vents. You should replace your filters every three months. If you have pets, you should replace them monthly.
