Why is My Furnace in Myakka, FL, Blowing Cold Air?

February 4, 2022

If you’re a resident of Myakka, FL, and experiencing cold air coming out of your furnace, this post is for you. There are various reasons our furnace may be malfunctioning, but the good news is that we can rectify it. If you want to know why your furnace is blowing cold air, read on to learn some reasons for this problem.

Thermostat Setting Error

The first thing that you should check is whether the thermostat switch is set to “auto.” If you have set it to “on,” the furnace will just run continuously without producing any heat.

Problem With the Computerized Controls

Newer furnaces have electronic control panels that might at some point require you to reboot them to reset the system. If the restarting process doesn’t rectify the issue, you might need to consult our HVAC experts.

Faulty Thermocouple

Another issue that might result in an extinguished pilot light is a malfunctioning thermocouple. The thermocouple senses and controls the ignition of gas valves. This kind of repair is best done by our skilled service technicians.

Damaged/Leaked Air Ducts

Damaged air ducts can suck in cold air from your crawlspace or attic. The holes in the ducts also allow the heated air to escape. You need to replace them.

Extinguished Pilot Light

Older furnaces develop a recurrent pilot light issue. If it keeps turning off for some reason, you can simply relight it. If this issue persists, you should consult us for technical assistance.

When the burner isn’t lit up, your furnace won’t heat. This will most likely be an issue with the pilot light. The other reasons the pilot light has issues include:

Clogged oil filter.
Faulty electronic ignition.
Compromised flame sensor.
Dirty gas burner or oil.
Limited gas supply.
