Why is my central heat blowing cold air? This is a fairly common question, and it happens to more people than you’d think. Sometimes, it means you’ll need to replace your heating unit. But in most cases, it’s a quick and simple fix! That’s why we’re here to help you identify and resolve the problem before it becomes an irreparable (and expensive) issue.
In this article, we’ll address this all-too-common concern: why is my central heat blowing cold air? Then, we’ll tell you how you can get your heater inspected by a professional for free!
Here are a few reasons your central heat is blowing cool air:
One of the most common reasons for central heat blowing cold air is restricted airflow. When your air filters become clogged with pollutants, it can inhibit the circulation of hot air through your system. This can cause your central heat to blow cold air instead. To fix this issue, you’ll need to change your air filters. It’s recommended that you change your air filters every three to four months to prevent this problem from happening in the future.
Another possible cause of central heat blowing cold air is a faulty circuit control board. The circuit control board serves as the “brain” of your central heat unit, sending signals to the blower and the burner. If the circuit control board is malfunctioning, it may not be sending the correct signals to the burner, resulting in cold air being circulated instead of hot air. To prevent this issue, you should have your unit cleaned and maintained regularly by an HVAC professional.
A third potential cause of central heat blowing cold air is an overheating unit. When your central heat unit is overworked and overheating, it will start blowing cold air as a safety feature to cool down. To prevent this issue, avoid overworking the unit. Rather than running it around the clock, set it on a timer to shut off automatically at regular intervals.
While most of these issues can be resolved fairly easily, you should avoid trying to fix your heater yourself. Instead, call a trusted HVAC technician! They’ll inspect your heater, diagnose the problem, and resolve it for you before it becomes a much larger problem. Request a free consultation today to get your heater inspected by a professional!
