4 Reasons Your AC is Not Cooling

Your "AC Not Blowing Cold Air"
Questions Answered

Spring and Summer in Ormond Beach and our surrounding area can get quite hot and it never fails that we get an influx of calls and asking these questions:

  • Why is my AC not blowing cold air?

  • Why is my AC not cooling?

  • Why won't my AC turn on?

  • Why is my AC not turning on?

  • Why is my AC blowing hot air?

  • Why is my AC not blowing cold air?

No matter how you phrase the question it means your house is hot and you are uncomfortable. 

There is nothing worse than feeling the warm air blowing out of the AC on a particularly hot day. Though our cooling services are always available in the Volusia and Flagler County area, it is important to understand what the root cause of the problem is. There are many causes for a central AC blowing warm air, some are silly, others are much more serious.


We put these Tips together to hopefully give you a little guidance on how to troubleshoot your challenges on your own.

Troubleshooting the AC Thermostat When Blowing Hot Air

Sometimes, the problem could be something as minor as having the thermostat set wrong. Always be sure to double check that the system is set to cool and that the fan is set on auto as opposed to on. If you’re lucky, this little change could potentially be the answer to your problem.

Dirty Working Conditions Can Cause AC To Not Blow Cool Air

Electrical Issues Can Cause An AC Unit To Not Turn On

A loss of power to the outside unit could create problems within the vent. Checking the circuit breaker and emergency shutoff switch is the best thing to do here. However, be mindful that if you are consistently checking the circuit breaker, you may have a serious electrical problem. If that is the case, reach out to a professional as soon as possible!

An AC Unit Not Cooling Can Be Caused By Low or Leaking Refrigerant

Low refrigerant is a fairly common reason for AC units to blow warm air, but it is one that cannot be solved with DIY fixes. Professional help is surely needed to figure out and solve this problem. If the refrigerant is not leaking, then maybe the air ducts are. Chances are your ducts are hidden in your walls, attic, or basement, and for that reason, professional help will be necessary to get to the bottom of the problem.
