Why Is My Furnace Blowing Cold Air?

Is your furnace running but blowing out only cold air? This is a fairly common problem that our technicians see here at New River Heating & Air in Radford. Before you give us a call, there are a few things you can try to troubleshoot the problem. If these don’t work, don’t worry; we offer fast, reliable furnace repairs for your home.

Air Filter Is Clogged

Clogged air filters limit airflow to your furnace, which can cause your furnace to overheat. Overheating decreases the system’s efficiency and can even cause premature component failure. When the furnace overheats, it will only make cold air. Luckily, the solution is quite easy: Simply replace the dirty air filter with a clean one to restore warm air.

Furnace Needs to Heat Up

It’s normal to feel a blast of cool air when your furnace first kicks on. The furnace needs to heat up before it can begin making warm air, which is why you may notice a few minutes of cool air at first. Once the furnace has pushed all the cold air out of the vents, you should begin feeling the room heat up. This should only take about five to 10 minutes. If a longer period of time goes by and you still have no warm air, then you may have a furnace problem that we can fix for you.

Pilot Light Is Out

Older gas furnaces rely on pilot lights to ignite the system when it needs to produce hot air. Modern furnaces rely on electronic igniters to do the job. When the pilot light burns out, your furnace can’t make hot air, which results in only cold air blowing from the vents. Our skilled technicians can repair the pilot light and restore your furnace’s performance.
