6.   WARRANTY PROCEDURE

 

For All Warranty Claims. Customer must register the product with National Comfort within 60 days from purchase.  Failure 

to timely register the product may void the warranty. Any claim for warranty shall be made within thirty days of discovery and in 

any event, within thirty days from removal of the compressor or part from the unit. Failure to make a timely claim shall void the 

warranty. Prior authorization from National Comfort is required for all warranty claims. Any claim for warranty must be first reported 

to National Comfort in writing specifying the unit, serial number, date of purchase and date of original installation. Customer shall 

also request a Return Material Authorization (“RMA”) from National Comfort to initiate the warranty claim process. Issuance of an 

RMA by National Comfort is not an acknowledgment that the defect is covered by this Warranty.  Any replacement compressor or 

part is warranted for the original product warranty, or for one year from the date of shipment of the replacement compressor/part, 

whichever is later. 
 

A.    Compressors.

  In addition to the above-referenced requirements, Customer is also required to purchase a 

replacement compressor and return the original compressor to National Comfort at National’s discretion.  If the defect is reported 

to National Comfort within one year from the date of original installation or within 20 months from the date of manufacture of the 

compressor (as determined by the compressor serial number), whichever occurs first, then Customer may take the compressor 

to any Authorized Copeland Distributor for replacement of said compressor.  If the defect is reported to National Comfort after 

one year from the date of installation or after 20 months from the date of manufacture of the compressor (as determined by the 

compressor serial number), whichever occurs first, but before the expiration of five years from the date of installation, then the 

compressor should be returned to National Comfort at National’s discretion and Customer shall purchase a new compressor.  If 

National Comfort determines that there is a defect in material or workmanship that is covered by this Warranty, then National shall 

credit Customer for the cost of the new replacement compressor.  If National Comfort determines that the defect in material or 

workmanship is not covered by this Warranty, then no credit shall be issued.  A copy of the invoice of the replacement compressor 

and completed RMA must accompany the compressor.  National Comfort, at its sole discretion, may also require Customer to 

supply the compressor tag.  The failure to follow this procedure shall render the warranty void. 
 

B.    Other Parts

. In addition to the above-referenced requirements, Customer is required to purchase a replacement part 

for the original part for which Customer is making a warranty claim.  The original part for which warranty is claimed is to be returned 

to National Comfort at National’s discretion, freight prepaid.  If National Comfort determines that there is a defect in material or 

workmanship in the part that is covered by this Warranty, then National Comfort shall credit Customer for the cost of the new 

replacement part.  If National Comfort determines that the defect in material or workmanship is not covered by this Warranty, then 

no credit shall be issued.  A copy of the invoice of the replacement part and completed RMA must accompany the original part 

for which warranty is claimed. National Comfort reserves the right to request additional documentation. The failure to follow this 

procedure shall render the warranty void.  

 

7.   SHIPPING INSTRUCTIONS 

 

A.  Compressors

.  Returned compressors must be totally secured by use of shipping lugs taken from the replacements 

compressors and clearly marked with the RMA number.  Do not use tape, rags or putty to seal the compressor.  Line connections

upright position.
