Is the heater in your Adel, Georgia, home blowing cold instead of warm air? If so, there’s a wide range of problems that could be causing this issue. This article can help you identify problems and help you troubleshoot them.

Thermostat Issues

Thermostat issues are a common cause of cold air production, and they’re usually easy to fix. First, bump the temperature settings up a few notches and see if the system starts producing warm air. Make sure your thermostat is set to "auto" and not "on." The "on" setting runs the fan but doesn’t produce warm air.

Dirty Air Filter

Something as simple as a dirty air filter can cause major problems. If you don’t change it regularly, your filter will become clogged with dust, affecting your indoor air quality and hindering your heater’s ability to operate. Check the filter, and change it if it’s dirty.

Pilot Light Issues

If you have an older furnace with a standing pilot light, make sure it’s lit. If it’s not, try to light it yourself. First, turn off your furnace. Next, turn off the reset switch. Wait a few minutes and turn the reset switch and furnace back on. If the pilot light won’t come on or continues to go out, get in touch with a service technician to have your furnace inspected.

Dirty Flame Sensor

Your furnace’s flame sensor determines if the burner is producing warm air and helps heat air as it moves through your ductwork. If this sensor gets dirty, it can cause your furnace to blow cold air.

To check for this issue, turn your unit off and on. If the air feels warm for a few seconds immediately after turning it back on and then becomes cold, you may have a dirty flame sensor. Contact a service technician to inspect and clean it. Cleaning a flame sensor requires opening the gas burner, and accessing it yourself is dangerous and could damage your unit.
