If your air conditioner is running but your home still feels warm and muggy, you’re not alone. This is one of the most common complaints we hear from homeowners across Alabama, especially during our hot, humid summers. While there are a number of possible reasons, most can be resolved quickly with the right help. At One Source Heating, Cooling, Plumbing & Electrical, we respond to every AC repair air conditioning problem by dispatching NATE-Certified technicians to your home or office.
1. Dirty Air Filter
A clogged filter restricts airflow and makes it harder for your system to cool the home. In Alabama’s pollen-heavy spring and dusty summer conditions, filters can get dirty fast. If it’s been more than a month since you checked it, start there.
2. Low Refrigerant
If your AC is blowing warm air, low refrigerant could be the culprit. This isn’t something that gets “used up” it usually means there’s a leak somewhere in the system. A licensed technician can locate the source and recharge your system properly. EPA Guide to Refrigerant Use and Safety
3. Frozen Evaporator Coil
It sounds strange, but a frozen coil can prevent your AC from cooling effectively. This often happens when airflow is restricted or refrigerant levels are low. If you notice ice forming on your unit, shut it down and call for service before the problem gets worse.
4. Thermostat Issues
Sometimes, the issue isn’t your AC at all it’s the thermostat. Make sure it’s set to “cool” and that the temperature is set lower than the room temperature. Also, check the batteries or consider upgrading to a smart thermostat for more reliable control.

5. Dirty or Blocked Condenser Unit
The outdoor part of your AC system plays a big role in heat exchange. If it’s covered in dirt, leaves, or grass clippings, it can’t work efficiently. Make sure the unit is clear of debris and has space to breathe.
