Reasons Why Your Heater is Blowing Cold Air

A heater should keep your home warm a while after turning it on. However, if you start your thermostat and notice the heater is blowing cold air, you should contact a qualified HVAC expert for assessment. Below are some reasons why your heater may be blowing cold air:

Dirty Air Filters

Air filters capture dust particles and debris from the air. If the filters are dirty, they will inhibit airflow through the furnace. For this reason, you should replace your air filters regularly, probably after three months of frequent use. Replacing dirty air filters can solve the cold air issue if your HVAC system doesn’t have other underlying problems.

At Blue Mountain Plumbing, Heating & Cooling, we offer quality HVAC repair services in Thornton and Denver metro areas. Our HVAC professionals will help you replace dirty air filters and identify other issues that may limit the efficiency of your system.

Faulty Thermostat

A thermostat alerts the HVAC system to turn on the heat when the room reaches a specific temperature. If your thermostat is faulty, it may cause your heater to blow cold air, particularly if it sends the wrong signals.

If you suspect your thermostat is faulty, schedule an appointment with us for a thermostat replacement service. We can also upgrade your current thermostat into a smart or programmable thermostat to ensure you get the comfort you deserve.

Faulty Furnace Control Panel

If the filters and thermostat are in top condition, but your heater keeps blowing cold air, you need to check the furnace control panel. You can quickly solve this by;

  • Turning off the furnace
  • Switching it on after a few minutes

This will reset the system, and if the issue persists, it’s time to schedule a furnace repair service.
