Understanding the role of deep cleaning evaporator coils in cooling your home is the best way to appreciate its importance. An evaporator coil is a heat exchanger that removes heat from indoor air so the blower fan can return cool air. Evaporator coils are located behind the air conditioning system and can accumulate much dirt if not cleaned regularly. These coils are not always inspected because they are hidden inside walls or in the basement. Cleaning your system will maintain its functionality and help extend its life. If the evaporator coil on your AC is dirty, it may cause the unit to malfunction.
Why Is It Important to Clean AC Evaporator Coils?
Dirt, dust, debris, and other pollutants can accumulate on the coil surfaces due to the close spacing between the coil fins and the volume of air that streams across them. Over time, dust buildup will reduce the system’s capacity to transfer heat into and out of the home over time and its ability to provide summer cooling. In more severe cases, dirty coils can also impede or block airflow, which is critical to the entire process. The HVAC experts at Pioneers Heating & Air listed down the issues that could result from a dirty evaporator coil:
Increased Operating Temperatures
The buildup of dirt, debris, and grime can make your system work harder than it needs to. In addition, the fans and compressors will operate at higher operating temperatures, causing your system to work harder.
Coils are supposed to absorb moisture from the air and send it outside. However, dirty coils will cause excess humidity inside your home and leave you uncomfortable, especially on hot summer days.
Reduced Cooling Efficiency
Dust and debris on the evaporator coils not only impede heat transfer but can also damage your air conditioning unit over time. When these are sucked into the compressor, they reduce pump performance and shorten the coil’s lifespan.
Increased Energy Costs
Due to filthy evaporator coils, your air conditioner will require more work to keep a cool environment, increasing energy bills. Thus, running an inefficient air conditioner will cost you more money.
A dirty or blocked evaporator coil can cause the compressor to run at higher temperatures, adding strain to the entire system. Because the compressor is such an expensive item to replace, it is critical to protect it from damage.
System Repairs or Replacement
Overstressed AC components can cause system failure, requiring parts replacement or installation of an entirely new system. However, you can keep your air conditioner running smoothly by avoiding excessive stress on the unit. Doing so can also save you on costly repairs at some point.
Tips for Cleaning Your AC Evaporator Coils
A brush can effectively remove small amounts of dirt on the evaporator coil. You can use compressed air if the accumulation of dirt on the evaporator coil is not too substantial. Additionally, it is advised to route the compressed air in the opposite direction of the regular airflow across the evaporator coil.
If you do not want to use commercial cleaners, you can consider using water and a light detergent. Simply combine detergent and warm water and pour the mixture into a spray bottle or garden hose. If your evaporator coils are that filthy, your best bet might be to use powerful cleaning agents. You will also want a pressure washer or a steam cleaner for tough cleaning.
