Cleaning & Servicing Microchannel Coils


Thanks to Luis Chacon at Trane Parts in Long Beach for providing this information!

As the cooling season moves into high gear, it is important to remember that Microchannel condenser coils are more susceptible to corrosion due to their aluminum construction, and cleaning with cleansers or detergents is strongly discouraged.

Why this is important to the parts organization: It is important that all service technicians and servicing contractors are aware of the proper cleaning techniques for Microchannel coils.  Cleaning the coil with water ONLY with a spray nozzle pressure below 600 psi is recommended.  Only in extreme cases should a chemical cleaner be used; one cleaner recommended is CHM00351,If a cleaner is used, it must be thoroughly rinsed with water even if the product is considered a “No Rinse” cleaner.
