On a sweltering summer day in Columbia, SC, and the surrounding areas, your air conditioner could reach its cooling capacity. It’s often an extremely hot and humid day that pushes the cooling system over the edge. Pay attention to these three signs that air conditioners often show just before you’ll need a professional AC repair.

Low Airflow

Poor airflow is a common air conditioner problem, and it’s often caused by a dirty filter, closed vent or obstructed duct. If you’ve already checked and replaced the filter and opened and cleaned the vents, it’s time to call for professional air conditioner repairs. Your air conditioner could have a dirty evaporator coil, electrical problem or issue with the air handler’s motor or fan. Routine maintenance helps you avoid dirty coils, but electrical and motor problems require skilled repairs.

Warm Air

The only thing worse than no air coming from your home’s ducts is warm air. If your cooling system has lost its cool, you’ll need an AC repair soon. There are many reasons why your air conditioning system could be blowing warm air. A bad thermostat, capacitor or dirty air filter are a few simple reasons. According to the Department of Energy, compressor failure or refrigerant leak could also cause warm air to blow out of your home’s vents. These are more extensive air conditioning repairs.

Loud or Unusual Sounds

The old saying about the squeaky wheel getting the grease applies to air conditioners, too. Loud or unusual sounds, such as banging, grinding, clanging or squealing, aren’t normal air conditioner noises. They’re signs of loose, worn, bent or damaged parts. If you hear hissing, a refrigerant leak could be the cause. Don’t delay calling for air conditioning repairs if you hear new loud or unusual noises during a cooling cycle.
