Why Is My Air Conditioner Blowing Warm Air?

Living in Florida, there are few things worse than finding your air conditioner is blowing warm air when you need relief from the heat. When it comes down it, there are lots of factors that can cause your air conditioner to blow warm air—some simple, some major.

Although you’ll need an HVAC technician to determine the root cause, here are three common explanations for why your HVAC system is blowing warm air.

A Frozen Unit

If your air conditioner is blowing warm air, check the condenser unit outside. Is it frozen? If so, this is likely the culprit behind the warm air. Lots of things can cause your air conditioner to freeze, including insufficient airflow, refrigeration issues, or the temperature outdoors. An HVAC professional will be able to determine the underlying cause and stop your unit from freezing over, which should remedy the warm air issue.

Refrigerant Leaks

A refrigerant leak is a common reason for an air conditioning unit to stop blowing cold air. An HVAC professional can test your unit for leaks, and repair the leak and replenish the refrigerant if necessary. Keep in mind that refrigerant can be dangerous, so don’t handle this issue yourself.

Thermostat Problems

In some cases, warm air can be coming out of your air conditioner because your thermostat was accidentally set to warm instead of cool. In other cases, the fan could be blowing out air even if your air conditioning unit is not working. You can often check out these issues yourself, but if your unit is still not working after changing the thermostat settings, a professional help should be called.
