Base Limited Warranty

Packaged Heat Pump

4WHC3 (Parts Only)     Models Less Than 20 Tons

Subject to the terms and conditions of this limited warranty, Trane U.S., Inc. (“Company’) extends a limited warranty against manufacturing defects for the product(s) 

identified in 

Table 1, 1A, 1B

 attached hereto (“Products’) that are installed in a residential application (personal, family or household purposes) under normal use and mainte-

nance in the United States and Canada.

  

This limited warranty applies to Products manufactured on or after August 1, 2011.

In order to maximize the available benefits under this limited warranty, the Purchaser (as defined below) should read it in its entirety.  All repairs of Product parts covered 

under this limited warranty must be made with authorized service parts and by a licensed HVAC service provider.  Additionally, commercial applications are treated differently 

under this limited warranty as stated in 

Table 1, 1A, 1B

 attached hereto.  For purposes of this limited warranty, “commercial applications” shall mean any application other 

than for personal, family, or household use.

TERM:

  The limited warranty period for Products is as stated in 

Table 1, 1A, 1B

 attached hereto.  If the Purchaser properly registers the Products, the limited warranty 

period shall be extended as stated in

 Table 1, 1A, 1B

 attached hereto.  Regardless of registration, the Commencement Date for a limited warranty period shall be the date 

that the original installation is complete and all Product start-up procedures have been properly completed and verified by an installer’s invoice.  If the installation and start-up 

date cannot be verified by the installer’s invoice, the Commencement Date shall be sixty (60) days after the factory manufacture date which is verified by the Product serial 

number.  Where a Product is installed in a newly constructed home, the Commencement Date is the date the Purchaser purchased the residence from the builder.  Proof of 

Product purchase, installation, and/or closing date of the residence may be required to confirm the Commencement Date.  

The installation of Product replacement parts under this limited warranty shall not extend the original warranty period.  The warranty period for any Product part replaced 

under this limited warranty is the applicable warranty period remaining under the original Product warranty.  

WHO IS COVERED:

  This limited warranty is provided only to the original owner and his or her spouse (“Purchaser’) of the residence where the Products are originally 

installed.   This warranty is not transferable except according to terms stated on the applicable website identified below under Registration Requirements.  Company has the 

right to request any and all proof of Product purchase or installation and/or closing date of the residence.

WHAT COMPANY WILL DO:

 Company may request proof of Product purchase and/or installation in order to provide Product parts under this limited warranty.  As 

Company’s only responsibility and Purchaser’s only remedy under this limited warranty, Company will furnish a replacement part to the licensed HVAC service provider, 

without charge for the part only, to replace any Product part that fails due to a manufacturing defect under normal use and maintenance.  The Purchaser must pay for any 

and all shipping and handling charges and other costs of warranty service for the replacement part.  If a Product part is not available, Company will, at its option, provide a 

free suitable substitute part or provide a credit in the amount of the then factory selling price for a new suitable substitute part to be used by the Purchaser towards the retail 

purchase price of a new Company product.  Any new Product purchase shall be at Purchaser’s sole cost and expense including, but not limited to, all shipping, removal, and 

installation costs and expenses.  

REGISTRATION REQUIREMENTS:

  All Products must be properly registered online by the Purchaser within sixty (60) days after the Commencement Date to receive 

the registered limited warranty terms.  To register online, go to:

• All Product parts replaced by Company under this limited warranty must be given to the servicing provider for return to Company.

• Air handlers, air conditioners, heat pumps, cased or uncased coils and stand-alone furnaces must be part of an Air Conditioning, Heating, and Refrigeration Institute

warranty.  In addition, all Products containing R-410A refrigerant include a liquid line filter drier which must be replaced when a compressor replacement is necessary.  A 

suction line filter drier must be added for compressors defined as burnouts.  Failure to comply with such filter drier requirements or the use of contaminated or alternate 

refrigerant or any non-approved refrigerant system additives including, but not limited to, dyes, will void this limited warranty.
