So, why is my central heat blowing cold air instead of hot air?

​Your central heat could be blowing cold air for several reasons, but we’re going to be talking about some of the most common issues:
 

• Restricted Air Flow: If your air filters are clogged, then your central heat will not be able to circulate hot air, and it will blow cold air instead. Check your air filters to see if they are clogged with pollutants and need to be changed. To prevent this problem in the future, you’ll need to have your air filters changed out every three to four months.
• Faulty Circuit Control Board: In some circumstances, your circuit control board can malfunction. Your central heat’s circuit control board serves as the brain for your unit. It sends out signals to the blower and the burner. If your circuit control board is malfunctioning, then it could be sending signals to the blower, but not the burner. This results in cold air being circulated rather than warmed air. To prevent this problem in the future, you’ll need to have your unit cleaned and maintained regularly by an HVAC professional.
• Overheating Unit: If your unit is overheating from overuse, it will start blowing cold air rather than hot air. This is a safety feature of most units to cool the unit down. To prevent this issue in the future, you’ll need to make sure that you’re not running your heater constantly and overworking the unit.
