The Settings on Your Thermostat

The first thing that you should check is the thermostat, and make sure that it’s in the right settings. If the thermostat is set to “ON”, the blower will continue running, even at times when the furnace isn’t heating the air. The vents will continue blowing cool air since there is no heated air from the furnace.

What you need to do is to turn the thermostat settings to AUTO, as this will allow the fan to run when the furnace is heating. Therefore, you will not get room-temperature or tepid air.

The Air Filter

Your furnace can overheat because of a dirty air filter as it prevents the air to flow in and out of the furnace—and this can also cause your vents to blow cold air. If the furnace overheats, its safety control will shut off its burners, and this will, in turn, because the fan to blow cool air instead of heated air.

Check Whether the Pilot Light Is On

There is a possibility that your furnace is blowing cold air since the pilot light isn’t on. The solution to this is pretty simple—just turn on the pilot light.

You should contact our professionals here at Honest Air in case you don’t know how to do it—they will be more than happy to offer the necessary assistance.

If you have installed a modern furnace, there is a possibility that you can control it with your smartphone or computer. At times, a glitch in the system will cause the vents to blow out cold air, and you will have to restart the system—just like you would restart your smartphone or computer.

Turning off the furnace for 30 seconds and then turning it on again can assist it to reset, and start functioning normally. If the furnace doesn’t function normally, even after restarting it, consider contacting one of our HVAC professionals to check what might be the problem with your furnace.

According to the US Department of Energy, leaking heated air to places like the basement or attic area can increase your utility bills significantly.
