MicroChannel Coil Cleaning


MicroChannel coils consist of tubes with microchannels running through the tubes.  The fins are welded to the tubes.  The coil is constructed of all aluminum.

Because the coil is all aluminum construction, care needs to be taken when cleaning the coil. Here are the simple guidelines for cleaning any microchannel coil:

MicroChannel Coil Cleaning Procedures

The use of chemical cleaners is not recommended. 

DRY CLEANING

  • A soft bristle (not wire) brush can be used.
  • A vacuum cleaner with a soft attachment can be used.
  • Compressed air blown from the inside out can be used.
    • (Do not contact the coil with the vacuum nozzle, air nozzle, or any other tool) 

WET CLEANING

  • Water pressure for cleaning should not exceed 100 psi
  • Use clean tap water sprayed from a nozzle on a garden hose from the inside.

If these procedures are followed, the microchannel coil will have a long, happy life.  I have attached a procedure sheet you can print out and keep with you on job sites.

About yorkcentraltechtalk

I have been in the HVAC industry most of my life. I worked 25 years for contractors on anything from residential to large commercial boilers and power burners. For the past 23+ years I had been employed by York International UPG Division ( a division of Johnson Controls) as a Technical support/Service Manager but I am now retired. One of my goals has always been to "educate" dealers and contractors. The reason for starting this blog was to share some knowledge, thoughts, ideas, etc with anyone who takes the time to read it. The contents of this blog are my own opinions, thoughts, experiences and should not be construed as those of Johnson Controls York UPG in any way. I hope you find this a help. I always welcome comments and suggestions for postings and will do my best to address any thoughts, questions, or topics you may want to hear about. Thanks for taking the time to read my postings!
