Is Your AC Running But Not Cooling? It Could Be a Dirty Evaporator Coil

Is Your AC Running But Not Cooling? It Could Be a Dirty Evaporator Coil

Florida’s sweltering heat makes a reliable air conditioner (AC) a non-negotiable. But what happens when you crank down the thermostat, your AC hums along, yet your home remains uncomfortably warm? The culprit could be a dirty evaporator coil, a critical component hidden within your indoor AC unit.

What is an Evaporator Coil, and What Does It Do?

The evaporator coil, also known as the “cold coil,” is a metal coil located inside the indoor unit of your split AC system. As warm air circulates over the evaporator coil, it absorbs heat from the air, causing the air to cool down. Moisture from the air condenses on the cold evaporator coil, forming water droplets that drain away. This cool, dehumidified air is then circulated throughout your home by the blower fan.

Why Does a Dirty Evaporator Coil Matter?

A clean evaporator coil is essential for efficient heat transfer. However, over time, the coil can become clogged with dirt,dust, pet dander, and other airborne debris. This dirt buildup acts like an insulator, preventing the coil from absorbing heat effectively. Here’s what happens when your evaporator coil gets dirty:

  • Reduced cooling efficiency: A dirty coil makes it harder for your AC to absorb heat from the air, leading to reduced cooling performance and increased energy consumption.
  • Frozen evaporator coil: In extreme cases, restricted airflow from a heavily clogged coil can cause the evaporator coil to freeze over, completely blocking airflow and preventing the AC from cooling your home.
  • Poor indoor air quality: Dirt and debris on the evaporator coil can harbor mold and mildew growth. As the AC circulates air, these contaminants can be released into your home, triggering respiratory problems for allergy sufferers.
