AC coils are an important part of your air conditioner and must be kept clean to function properly. The coil is responsible for cooling the house, and if it is dirty or clogged it will not dissipate heat efficiently. This can cause many problems, such as: Reduced energy efficiency: Dirty coils can cause the air conditioner to work harder and consume more energy to cool the home. This results in higher energy costs. Frozen coils: Dirty coils can cause the air conditioner to freeze, which can lead to other problems such as reduced airflow and water damage. Reduced cooling capacity: When a battery gets dirty, it cannot transfer heat efficiently, resulting in a decrease in cooling capacity to maintain a comfortable temperature in the home. Short Cycle: If the coils are dirty, the air conditioner may turn on and off more frequently, known as short cycle. This causes unnecessary wear and tear on the system and even shortens its service life.
