Why Your AC Is Blowing Warm Air: Common Issues in Columbia Homes

July 22, 2025

AC blowing warm air?

Nothing is more frustrating on a hot summer day in Ashland, MO than switching on your AC and feeling warm air pouring through the vents. When your air conditioning system fails to cool, it can be due to a variety of issues—some simple, others more serious. Knowing the most common causes can help you decide when to troubleshoot and when to call in the pros.


One of the first things to check is your thermostat. Make sure it's set to “cool” and that the temperature is set lower than the current room temp. It sounds obvious, but it’s a quick fix that many overlook. If the settings are fine and you're still not feeling cold air, the next likely culprit is low refrigerant. AC units rely on refrigerant to absorb heat from the air, and if there’s a leak, your system won't be able to cool properly.


Clogged or dirty air filters are another frequent issue. When airflow is restricted, your AC has to work harder—and often still can't deliver the cooling you expect. Changing the filter is an easy DIY task that can restore function if that’s the root cause. You should also check your circuit breakers. A tripped breaker or faulty wiring can cut power to essential components, leaving your AC unable to perform.


Another common issue is frozen evaporator coils. These coils are responsible for absorbing heat from your indoor air. When they freeze up due to poor airflow or refrigerant issues, your AC can no longer operate effectively—and may even blow warm air as a result.
