The 5 Most Common Reasons Your AC Is Blowing Warm Air

Here are the top five reasons your air conditioner is blowing warm air and what you should do about it.

1. Thermostat on the Wrong Setting

If your air conditioner is blowing warm air and you’re unsure why, check the thermostat first — even if you’re positive it’s on the right setting.

It’s not uncommon for homeowners to accidentally switch the thermostat to the ‘OFF’ or heating position without realizing it.

Check the thermostat batteries too and replace them if they’re expired.

2. Clogged Air Filter

Air filters might be the most underrated component of air conditioning systems. But these devices work hard to filter out dander, dirt, dust and other icky debris.

To work effectively, air filters need to be changed or cleaned on a regular basis. If your AC is blowing hot air, the air filter might be too dirty and impeding the flow of cool air as a result.

3. Frozen Air Conditioner

A frozen air conditioner isn’t an unusual sight — even in the heat of the Sunshine State. But when this happens, it can cause your system to produce hot air.

Check the outside component of your system and see if there is any ice. If there is, this is the likely culprit.

Air conditioners freeze for two reasons:
1. Refrigerant Leaks
2. Blocked Airflow

While the remedy could be as simple as changing the air filter for the latter, refrigerant leaks should be handled by a professional, so we recommend scheduling an appointment.

4. Refrigerant Leak

Speaking of refrigerant leaks — this issue can cause your air conditioner to blow warm air too. Remember, refrigerant does not need to be refilled, so if there is a leak, you need to call a professional.

Exposure to refrigerant can be dangerous for humans and pets, so be sure to act promptly.

5. Blown Breaker Switch

There are multiple components that make up an air conditioning system, and if one stops working, the whole system can fail. If the breaker switch fails, it will halt power to the outside unit and impede the production of cool air.

If this is the case, the first thing you should do is check the breaker and see if anything has tripped. If so, reset it and see if this remedies the problem. If the problem persists, it could be indicative of an underlying electrical issue, and you should call a professional electrician.
