Introduction
During the summer months, air conditioning units provide great comfort for users. Sadly, most of the systems have dirt and debris accumulation on the evaporator coils which leads to decreased efficiency. Regular maintenance sessions should indeed polish the coils, as that cleaning step has the potential to boost performance. In this guide, we discuss the right brush for cleaning an evaporator coil, and focus on how this total action influences the lifespan and overall productivity of the AC system.
What is an AC Evaporator Coil?
Evaporator coils are important components of your air conditioning system. It is located in the indoor unit where it extracts heat from air, and cools living spaces. The cool air in the system is maintained by the evaporation of refrigerant present in each coil.
The cooling process will not work without proper ventilation of the air above the evaporator coil. When exposed for long periods with no movement, the coils tend to become covered with dirt. This system is more dependent on coarse airflow, but works less efficiently tautologous because of the lip of the airstream rim of the heating element which will lead to increase in power costs.

Why is Cleaning the Evaporator Coil Important?
The evaporator coil tends to accumulate dirt, dust, and debris over time. This accumulation impacts the cooling process’s efficiency and the quality of air inside the house. Clogged evaporator coils also cause a noticeable increase in the energy consumption of the air conditioning unit, raising operational costs due to the excessive strain placed on the system.
Moreover, the coil may also freeze due to the debris build up leading to a potential catastrophic failure of the entire system.Regular cleaning of the evaporator coil improves the efficiency of the system, boosts indoor air quality, and helps prolong the lifespan of the AC unit.
Cleaning the AC evaporator coil ensures your system runs efficiently, reduces energy costs, and improves air quality. Regular AC coil cleaning helps prevent breakdowns and extends your system’s lifespan.
