Why Is My Furnace Blowing Cold Air?

December 16, 2021 | Blog

During the cold months, the last thing a homeowner wants to deal with is their furnace blowing out cold air. This issue can be caused by several different factors. Fortunately, this problem can be easily prevented with a seasonal tune-up.

At Air Tech of Conroe, we understand how frustrating this furnace problem can be. That’s why we’ve compiled this helpful troubleshooting guide. We also offer effective heater repair Conroe homeowners can rely on when their furnace is in dire need of a fix.

Check the Thermostat

Oftentimes, a heater fails to blow out warm air because of a thermostat malfunction. The thermostat is responsible for communicating to the furnace to blow out warm air. When it isn’t sending the right signals, the entire system will fail to work properly, leaving you with a chilly home. 

Your thermostat may be malfunctioning or failing to work at all. Consider investing in a programmable or smart thermostat for a more convenient and energy-efficient heater.

Replace the Air Filter

HVAC technicians recommend replacing your air filter every 90 days. Failure to do so may result in a build-up of dust and debris, which can impact the entire heater. Some of what can collect in your air filter includes:

  • Dust
  • Dirt
  • Mold
  • Dandruff

When an air filter is clogged with dirt, movement within the unit is significantly hindered. This can raise the internal temperature, causing the heating cycle to shut down to prevent any damage or fires. 

Replacing the air filter may allow the system to run properly again. It will also help improve the air quality of your home. 

Inspect Control Panel

The electronic control panel may be malfunctioning if your unit blows out cold air. This issue may be fixed in just a couple of easy steps.

First, turn off the power to the furnace. After waiting a few minutes, flip the switch back on. If this doesn’t correct the problem, attempt other troubleshooting methods. 

If you aren’t an electrician, don’t attempt to do any more work with your furnace’s electrical components, as you may seriously harm yourself. Leave all potentially dangerous work to professionals. 

Schedule Regular Tune-Ups

The best way to ensure your heater runs properly all year long is to schedule a seasonal tune-up. Furnace maintenance can catch any issues before they evolve into bigger problems that might result in the output of cold air. 

Some troubleshooting options may be dangerous to perform on your own if you’re not an HVAC professional. A technician will be able to detect any problems within your unit during a tune-up and can resolve them to save you money on future repairs or replacements.
