Why is My Furnace in Brays Island, SC, Blowing Cold Air?

Furnace Repair

A furnace that’s in tiptop condition can give you a feeling of peace of mind. However, one that’s doing strange things can be more than a little bit unsettling, so you’ll need to get it checked out. If you notice your furnace in Brays Island, SC, blowing cold air, get to the bottom of the situation without any hesitation.

Thermostat Problems

If your furnace is blowing cold air, a problematic thermostat setting could be the big reason. If you’ve set it to “ON” rather than “AUTO,” that could be the trigger. This setting makes fans run nonstop and stops them from giving off heat entirely as well.

If you restore the AUTO setting, you should be good to go. Your space should start feeling nice and warm again.


It’s critical to switch your air filter on a routine basis. If you fail to do so, it could lead to airflow that isn’t exactly up to par. This can bring on serious furnace overheating concerns. To maximize heating efficiency and maintain good air quality, change the filter every month.

Overheating can turn your burner off. That’s what brings on the total absence of air that’s hot. It can be wise to switch the air filter and turn the furnace back on.

Valve Woes

Do you have a valve that just won’t light up regardless of what you do? If your response is yes, a gas valve that isn’t working in the appropriate manner may be the cause.

Has it been ages since your last system cleaning session? If it has, you may have a valve that’s unable to move as the result of significant debris accumulation. Call Howell-Chase Heating & Air Conditioning for information about furnace repairs and maintenance. We’ll make sure your heating system is operating at peak efficiency when you need it most.
