Why Is My Air Conditioning Unit Blowing Warm Air?

When you turn on the air conditioning in your home, you expect it to cool you off, especially during a hot afternoon. But your home’s air conditioning unit has many parts that must work together to produce cool air, and when one part breaks, the entire system can malfunction. Blowing warm air is a common problem our Florida residents notice with their home air conditioning systems. But, what does it mean?

When your air conditioner is blowing warm air, a number of problems could be the cause. Here are a few of the most common causes:

Refrigerant Leak

Refrigerant leaks are typically random and highly unpredictable. They could be due to a poor installation job or just because of wear and tear over time. Heavy use of your air conditioning system, especially if it has been turned off during cooler months, can especially cause damage. Seasonal maintenance on your unit can help to prevent these types of leaks in the future!

If you think your system is blowing warm air because of a refrigerant leak, it’s best to contact the experts and explain your air conditioning issue. Refrigerants are dangerous and should only be handled by a professional technician.

Frozen Air Conditioner

Did you know your air conditioner could freeze? Even in the Florida sun, if your air conditioner is set on the highest setting and runs for too long, it could potentially freeze. A frozen AC unit is the most common cause of warm airflow. To keep this from happening, it’s best to keep your air conditioning’s thermostat set on a normal, but still comfortable temperature.

If you think your air conditioner is already frozen, call a service technician.

Thermostat Settings

Before you call an HVAC technician, check to make sure your thermostat is turned on and set to cool. If you, or someone in your house, accidently set the thermostat to warm, the unit will blow warm air to maintain the current temperature. It gives the illusion that your system is broken, when actually the fix is as simple as flicking a button!

Dirty Air Filter

If you do not replace your air filters on a regular basis, they are going to collect dust and dirt from your home—and the blockage will make it much harder for your air conditioner to run efficiently. Like the thermostat, check your air filters before calling a professional HVAC service!

Electrical Wiring Issue

Electrical wiring issues are a rare occurrence, but they are not to be ruled out as a cause for warm air in your home. If you’ve checked out the thermostat and the air filters and are certain your unit is not frozen or leaking, you could have a problem with the wiring. Call and schedule an air conditioning repair to assess your unit’s electrical status and replace any broken wires as soon as possible.
