What To Do If Your Furnace is Blowing Cold Air


Did you turn on your furnace recently only to find that it was blowing cold air? If so, this is a very common problem that HVAC owners can have but the good thing is that it can be fixed.

In this article we will share with you several reasons why your HVAC unit is blowing cold air and what you can do to resolve this issue.

#1 – The Thermostat Is Set Incorrectly

One first reasons why your HVAC unit is blowing cold air could be due to the your HVC being set incorrectly to ON, instead of being set to heat. If this is the case, simply switch your thermostat to the correct setting and it should resolve the problem immediately.

#2 – Dirty Air Filter

Another reason why your furnace is blowing cold air could be due to your HVAC unit having a dirty air filter.

If the filter is dirty, this will block air from flowing through your system normally and ultimately shut off your burners. This is why you should safely check your HVAC filter and if it needs to be replaced, you should replace the dirty filter with a clean HVAC filter.

#3 – Pilot Light Is Not Working

Last of all, but most important, another common reason why your Frederick County HVAC may be blowing cold air could be due to your pilot light being out.

Pilot lights can go out for a variety of reasons including just blowing out, or lighting incorrectly. Regardless of the reason, if your pilot light is not working, it will need to be examined for a possible blockage, dirt or damage to the thermocouple.
