Congratulations on purchasing your new HVAC equipment. It’s been 

designed for long life and reliable service, and is backed by one of the 

strongest warranties in the industry. Your unit automatically qualifies 

for the warranty coverage listed below, providing you keep your 

proof of purchase (receipt) for the equipment and meet the warranty 

conditions.
LIMITED TEN (10) YEAR EXPRESS WARRANTY

MARS warrants all parts of the HEW/HNW residential geothermal heat 

pump including the compressor to be free from defects in workmanship and 

materials for normal use and maintenance for ten (10) years from the date of 

purchase by the original consumer for the original installation. This Express 

Limited Warranty applies only when the geothermal heat pump is installed 

as a complete matched system, and only when the system is installed per 

MARS installation instructions and in accordance with all local, state and 

national codes for normal use.

LIMITED FIVE (5) YEAR LABOR ALLOWANCE

Labor is allowed for warranty service for a period of five (5) years from the 

date of purchase when the unit is properly registered and commissioned 

according to the start-up procedure specified in the Installation/Operation 

Manual, and when the Geothermal Start-Up Certification Form is completed 

and submitted to MARS.

EXCEPTIONS

The Limited Express Warranty does not cover normal maintenance—MARS 

recommends that regular inspection/maintenance be performed at least once 

a season and proof of maintenance be kept. Additionally, labor charges, 

transportation charges for replacement parts, replacement of refrigerant 

or filters, any other service calls/repairs are not covered by this Limited 

Warranty. It also does not cover any portion or component of the system that 

is not supplied by MARS, regardless of the cause of failure of such portion or 

component.

CONDITIONS FOR WARRANTY COVERAGE

•  Unit must be operated according to MARS operating instructions included 

with the unit and cannot have been subjected to accident, alteration, 

improper repair, neglect or misuse, or an act of God (such as a flood)

•  Installation was done by a trained, licensed or otherwise qualified HVAC 

dealer/contractor

•  Performance cannot be impaired by use of any product not authorized by 

MARS, or by any adjustments or adaptations to components

•  Serial numbers and/or rating plate have not been altered or removed
•  Damage has not been a result of inadequate wiring or voltage conditions, 

use during brown-out conditions, or circuit interruptions

•  Air flow around any section of the unit has not been restricted
•  Unit remains in the original installation
•  Unit was not purchased over the internet

DURATION OF WARRANTY & REGISTRATION

The warranty begins on the date of purchase by the original consumer. The 

consumer must retain a receipted bill of sale as proof of warranty period. 

Without this proof, the express warranty begins on the date of shipment from 

the factory.

REMEDY PROVIDED BY THE LIMITED EXPRESS WARRANTY

The sole remedy under the Limited Warranty is replacement of the defective 

part. If replacement parts are required within the period of this warranty, 

MARS replacement parts shall be used; any warranty on the replacement 

part(s) shall not affect the applicable original unit warranty. Ready access 

to the unit for service is the owner’s responsibility. Labor to diagnose and 

replace the defective part is not covered by this Limited Express Warranty. If 

for any reason the replacement part/product is no longer available during the 

warranty period, MARS shall have the right to allow a credit in the amount of 

the current suggested retail price of the part/product instead of providing repair 

or replacement. 

LIMITATION OF LIABILITY

1.  There are no other express or implied warranties. MARS makes no 

warranty of merchantability. We do not warrant that the unit is suitable 

for any particular purpose or can be used in buildings or rooms of any 

particular size or condition except as specifically provided in this document. 

There are no other warranties, express or implied, which extend beyond 

the description in this document. 

2.  All warranties implied by law are limited in duration to the seven-year term 

of the parts warranty. Your exclusive remedy is limited to the replacement 

of defective parts. 

We will not be liable for any consequential or 

incidental damages caused by any defect in this unit. 

3.  This warranty gives you specific legal rights and you may also have other 

rights which vary from state to state. Some states do not allow limitation 

on how long an implied warranty lasts or do not allow the exclusion or 

limitation of incidental or consequential damages, so the above limitations 

or exclusions may not apply to you.

4.  No warranties are made for units sold outside the continental United States 

and Canada. Your distributor or final seller may provide a warranty on units 

sold outside these areas.

5.  MARS will not be liable for damages if our performance regarding warranty 

resolution is delayed by events beyond our control including accident, 

alteration, abuse, war, government restrictions, strikes, fire, flood, or other 

acts of God.

HOW TO OBTAIN WARRANTY SERVICE OR PARTS

If you have a warranty claim, notify your installer promptly. If the installer 

does not remedy your claim, write to MARS, 1900 Wellworth Ave., Jackson 

MI 49203. Enclose a report of inspection by your installer or service person. 

Include model number, serial number, and date of purchase.

Owner responsibilities are set forth in the 

instruction manual—read it carefully.
