Compressr Change-outs — Addendum

I almost forgot to mention one more part that is very important and that is — What type of refrigerant is your system?”  When I first started in this industry, there were systems with R-500, R-502, R-12, R-22 and a few other odd balls too.  You never put your gauges on a system until you first looked at the data plate to see what type of refrigerant was in the system.  Then the industry standardized on R-22.

Today, you have systems with R-22, R-410A, R-407, even a few with R-134A.  You need to get back into the practice of looking at the unit data plate to see the type of refrigerant is in the system you are working on.  This is both for SAFETY as well as proper diagnostics.

You also need to look at any replacement compressor to make sure it has the correct refrigerant type and oil and matches the unit you are working on.

Sorry I missed this valuable point in the first post (even I still read what I write to make sure I get it right √ ).  Also, there are a lot of different alternative refrigerants out there being used.  You might look at my post on that subject but briefly — alternative refrigerants will void any manufacturer’s warranty so be careful if you use them.

This should now give you what you need to make sure the replacement compressor is done correctly and has a very good chance of lasting  very long time.


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!
