Is Your Heater Blowing Cold Air?

If your heating system is blowing cold air instead of warm air, there could be several reasons for this issue. Here are some common reasons why a heating system may not be producing warm air:

Thermostat Settings:

  • Check to see if the fan is set to ‘On.’ If it is, then it will blow air continually, whether or not the furnace produces heat. If your furnace always blows air, sometimes hot and sometimes cold, then it’s likely a fan setting issue.

Dirty or Clogged Air Filters:

  • Dirty or clogged air filters can restrict the airflow, reducing the efficiency of the heating system. Regularly replace or clean the air filters to ensure proper airflow.

Faulty Thermostat:

  • A malfunctioning thermostat may not accurately detect the temperature or control the heating system properly. 

Issues with the Ductwork:

  • Leaks, blockages, or disconnections in the ductwork can result in the loss of warm air before it reaches the rooms. Action Air’s trained HVAC technicians can inspect the ductwork for any issues and repair or replace damaged sections.

Fuel Supply Issues:

  • It’s possible a gas furnace won’t heat because it’s not getting a proper gas supply. This is another scenario where the furnace will blow cold air and then shut down.

Pilot Light or Ignition Issues:

  • For gas-powered systems, a malfunctioning pilot light or ignition system can prevent the system from producing heat. 

Regular maintenance and timely repairs can help prevent such issues and ensure the efficient operation of your heating system.
