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 ONE (1) YEAR EXPRESS WARRANTY

Comfort-Aire

 warrants this Room Air Conditioner to be free from 

defects in workmanship and materials for normal use and 

maintenance for one (1) year from the date of purchase by the 

original consumer. This Express Limited Warranty applies only when 

the Room Air Conditioner is installed and operated per 

Comfort-Aire

 

installation and operating instructions for normal use. 

EXCEPTIONS

The Limited Express Warranty does not cover normal maintenance 

Comfort-Aire

 recommends that regular inspection/maintenance be 

performed at least once a season. Additionally, labor charges  

diagnostic charges, transportation charges for replacement of 

refrigerant or filters, and 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 

Comfort-Aire

regardless of the cause of failure of such portion or component.

CONDITIONS FOR WARRANTY COVERAGE

Unit must be operated according to Comfort-Aire 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)

• Serial numbers and/or rating plate have not been altered or

removed

Performance cannot be impaired by use of any product not

authorized by 

Comfort-Aire

, or by any adjustments or

 

adaptations

to

 

components

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

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 unit. Labor to diagnose and replace the defective unit is 

not covered by this Limited Express Warranty. If for any reason 

the replacement product is no longer available during the warranty 

period, 

Comfort-Aire

 shall have the right to allow a credit in the 

amount of the current suggested retail price of the product instead 

of providing replacement. 

LIMITATION OF LIABILITY

1.

There are no other express or implied warranties. 

Comfort-Aire

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 one-term

of the warranty. 

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. Comfort-Aire

 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.
