Coil Cleaning

Dirty Coils Waste Energy and Cost Money

A coil fouled with dirt and grime cannot supply proper heat transfer and results in greater energy consumption. Equipment operating with dirty coils can use up to 37% more energy than those with clean coils. Additionally, a dirty system’s cooling capacity can be reduced by as much as 30%. Dirty coils increase operating pressure and temperatures that breakdown the compressor’s lubricant and can result in equipment failure. A failed compressor means no cooling and costly repair.


How to Clean Coils

The most popular cleaning method to clean coils is pressure washers.   Pressure cleaning should be done in the opposite direction of air flow through the coil.  A cleaning solution can be applied with a hand sprayer before pressure washing or by using the built in chemical injection system.  Care must always be taken when using a pressure washer to avoid damaging the fins on the tubes.  Water leaving the coil should be free of particulate.  If it is not, repeat the process.


 Different types of coils required different methods to effectively clean and rinse the coils and drain pan.
