Know Your Evaporator Coils And Increase Efficiency Through Airflow

Evaporator and condenser coils are essential to providing Tampa Bay homes with cool air. Air conditioning coils accumulate dirt as they’re used, which reduces efficiency. This is due to the configuration of the coils themselves, which incorporate small, tight spaces where dirt can build up and restrict airflow, reducing efficiency and comfort.

When your air conditioner cycles on, cold, compressed refrigerant moves through the evaporator coil. At the same time, the blower moves warm air from your living space through the tight spaces and cooling fins on the evaporator coil. As the warm air moves over the cold coil, the coil removes the heat from the air. The cool air can then be circulated through the ductwork to reach your living space. The refrigerant is converted into a gas, and transferred to the condenser coil.

The “evaporator coils” evaporate liquid refrigerant into gas. The “condenser coils” condense the gas refrigerant back into liquid, and the cycle continues until the air in your home is cool according to your thermostat settings.

If your air conditioning coils become clogged with particles like dust, pollen, soot or mold, a variety of problems can develop:

  • Restricted airflow
  • Imbalanced refrigerant levels
  • Inefficient performance
  • Reduced equipment life span
  • Reduced comfort
  • Rising utility payments
  • Frozen evaporator coils
  • Damaged or overheated compressor

Neglected preventive maintenance often results in dirty coils. In systems that have been neglected for long periods, a thick gray layer of dust, dirt, and even ice can virtually stop airflow altogether.
