Replacement Part Warranty

Replacement parts are warranted for ninety (90) days or the balance of the original warranty, whichever is greater. All replacement parts must be approved Company parts obtained through the company’s local distributor.

Labor warranty is to repair or replace defective components provided that the work is performed by a service provider acceptable to the Company. Such charges shall be determined in accordance with the Company’s current labor time guide and shall exclude charges for overtime, travel time, mileage or other premium charges, which shall be the sole responsibility of the owner.
