1.

   National Comfort Products warrants to its customers that its product shall be free from defects in material and 

workmanship under normal use and regular service and maintenance as follows:
 

COMPRESSORS:

 For five years from the date of original installation.  

  

ALL OTHER PARTS:

 For all other parts except the Compressor, for two years from the date of original installation.    

 

Customer must register the product within 60 days of purchase.  If Customer cannot adequately document date of 

installation, then, for purposes of determining the warranty period, the date of installation shall be 60 days from the date of 

purchase. The 2 year parts warranty is effective for units purchased after January 1, 2016.

 

2.

   This warranty does not extend to any damages or losses due to misuse, accident, abuse, neglect, normal wear and 

tear, negligence (other than National Comfort’s), unauthorized modification or alteration; use beyond rated capacity; unsuitable 

power sources or environmental conditions; improper installation, repair, handling, maintenance or application; damage as a 

result of fire, wind, floods, lightning, or corrosive conditions; or any other cause not the fault of National Comfort.  By way of 

example and without limitation, the following do not constitute a defect in workmanship and materials and are not covered by this 

warranty: slugging of liquid refrigerant or oil, unstable line voltage, lightning, operating without proper lubrication, and operating 

without factory provided safeties.  Any installation that impairs or impedes air flow negatively impacts performance and causes 

premature equipment failure that voids this warranty.  For example, installation behind a brick façade or the addition of a brick 

pattern façade, i.e. pigeon holes impedes air flow and shall void this warranty. 

 

3.

   

SOLE WARRANTY 

 

 

The warranties identified herein constitute National Comfort’s sole and exclusive warranties with respect to the goods 

and are in lieu of and exclude all other warranties, express or implied, arising by operation of law or otherwise, including without 

limitation, merchantability and fitness for a particular purpose whether or not the purpose or use has been disclosed to National 

Comfort in specifications, drawings or otherwise, and whether or not National Comfort’s goods are specifically designed and/or 

manufactured by National Comfort for Customer’s use or purpose.

 

4.

   

LIMITATION OF REMEDY

 

The sole and exclusive remedy for breach of any warranty hereunder (other than the warranty provided herein) shall be 

limited to repair, replacement, credit or refund of the purchase price to distribution as set forth herein.  

 

National Comfort is not responsible for any other item including but not limited to local transportation, freight, removal of 

any compressor or part, any labor associated therewith, service or diagnosis calls, refrigerant, or costs for returning any defective 

compressor or part.  

 

5.

  

LIMITATION OF WARRANTY

 

NATIONAL COMFORT MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED, ORAL OR WRITTEN, RELATED 

TO THE GOODS, INCLUDING ANY WARRANTY OF MERCHANTABILITY OF FITNESS FOR A PARTICULAR PURPOSE, 

WHICH ARE EXPRESSLY DISCLAIMED.   NATIONAL COMFORT SHALL NOT BE LIABLE FOR SPECIAL, INCIDENTAL, OR 

CONSEQUENTIAL DAMAGES OR LOSSES FROM ANY CAUSE WHATSOEVER, INCLUDING, WITHOUT LIMITATION, LOSS 

OF USE, COMMERCIAL PROFITS, OR CUSTOMER GOODWILL, AND ANY OTHER CLAIMS BASED ON CONTRACT OR 

TORT, WHETHER OR NOT ARISING FROM NATIONAL COMFORT’S NEGLIGENCE. 
 

National Comfort shall not be liable for damages caused by delay in performance and the remedies of Customer set forth 

in this agreement are exclusive.  In no event, regardless of the form of the claim or cause of action (whether based in contract, 

infringement, negligence, strict liability, other tort or otherwise) shall National Comfort’s liability to Customer and/or its customers 

exceed the price paid by Customer for the specific goods or portion of the goods provided by National Comfort giving rise to the 

claim or cause of action, and Customer shall indemnify and hold harmless National Comfort for any damages incurred by National 

Comfort in excess thereof.  Customer agrees that in no event shall National Comfort’s liability to Customer and/or its customers 

extend to include incidental, consequential, or punitive damages.
