Compressor Warranties


As all of you are aware, the Federal Government mandated that residential, single phase, condensing units manufactured after January 23, 2006 achieve a minimum S.E.E.R. rating of 13.00.  Typically, for a new condensing unit to achieve 13.00 S.E.E.R., it would also be necessary for the contractor to change the evaporator coil to one specifically designed to meet this efficiency level requirement and also be certified in the ARI directory as a compatible match to the condensing unit. 

The industries and compressor manufacturer’s current position regarding compressor warranties on UN-matched (non-ARI certified) systems is that the compressor warranty MAY be voided if the condensing unit is not matched to a compatible, ARI certified, evaporator coil.  Dealers can check the applicability of any system match up (condensing unit / coil) on ARI’s website prior to installing a new condenser. 

York’s revised Warranty Claim Form now contains a section that specifically asks the dealer to identify whether the coil has an expansion valve device or not and to answer the question, “Is this an ARI matched system?”  Further, if the dealer indicates that it is a matched system, the claim form requests the Brand Name, the Model, the Serial Number, and the ARI rating of the coil. The ARI rating is the Reference# found on their web site showing that it is an ARI “Matched” system. 

To protect your customer’s investment (and peace of mind), it is strongly recommended that all installations of 13 (and higher) S.E.E.R. condensing units be accompanied by an ARI matched evaporator or fan coil.  Failure to do so may void the compressor warranty on the condensing unit.

NOTE: This is also true if you are using the “dry charged” R-22 unit as a replacement unit.  The coils still needs to be matched since this is a 13 SEER unit. The “dry charged” R-22 unit can be used as a replacement unit for units with less than 13 SEER ratings as long as the coil is replaced to bring the system up to at least the required 13 SEER .

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!
