Humble Air Conditioning Repair & Maintenance

Common Causes For a Malfunctioning Air Conditioning System

Low Refrigerant Levels: Refrigerant doesn’t get used up or burned in an air conditioning system. If your refrigerant is low, it’s either due to a leak or an insufficient fill during installation. Low refrigerant forces your system to work harder to produce cool air, reducing efficiency and increasing wear and tear.

Dirty Condenser Coil: Over time, dirt, grime, and debris can accumulate on your air conditioner’s condenser coil. When the coil is covered in dirt, it becomes harder for the refrigerant to condense back into liquid form, which drastically reduces your system’s ability to cool your home effectively.

Clogged Drain Line: As your AC runs, condensation forms on the evaporator coils and is collected in a drip pan, where it’s drained away through a tube. If this drain line becomes blocked, water can back up into the system, freeze over the evaporator coil, and severely hinder your AC’s performance.

Electrical or Sensor Issues: Your AC’s compressor and fan rely on electrical current to operate. A faulty electrical control or broken connection can disrupt power and prevent the system from working properly. Additionally, malfunctioning thermostat sensors may cause your system to either run continuously or fail to turn on when needed.
