Anesi Product Warranty

Stone Mountain Technologies, Inc. Anesi Limited Warranty February 2024

Stone Mountain Technologies, Inc./SMTI (“Company”) provides this limited warranty to end users, (“Purchaser”) of Anesi-brand products including the gas absorption heat pump and air handling unit (hereafter referred to as “Appliances”). Installation, operation, or use of Appliances constitutes acceptance of these terms. For purposes of warranty registration options, the Company offers an online tool for homeowners and contractors to access Appliance data and warranty registration, referred to as the “APP”. Subject to the terms and conditions herein, the Company extends a limited warranty to the original Purchaser that the specific Appliances will be free of failure caused by manufacturing defect, under normal use and service, for the period defined in Table 1. As the Company’s only responsibility and the Purchaser’s only remedy under this limited warranty, Company will furnish a replacement Appliance part or sub-component, or at Company discretion, the entire Appliance, if deemed appropriate, for installation by licensed HVAC service provider, without charge for the part only, to replace any Appliance part or sub-component that fails due to a manufacturing defect under normal use and maintenance. Labor charges will be covered by this warranty to the extent as described in Table 1. The Purchaser must pay for all shipping and handling charges and other costs of warranty service for the replacement part or replacement Appliance.

About Your Warranty:

The warranty period begins on the date the original installation is completed as documented by the installer’s invoice. This invoice must contain the Appliance model/serial numbers. If the installation date is not recorded on the installer’s invoice, the warranty period will begin sixty (60) days after the factory manufacture date, as determined by the Appliance serial numbers. This limited warranty covers Appliance parts, for the respective timeframes, for installations in the United States or Canada, as noted in Table 1. Residential and Commercial installations have different warranty terms; refer to Table 1 for details. The purchaser must pay any repair charges not covered by this warranty. The Purchaser is responsible for any premium charged for overtime labor requested by Purchaser and for any service and/or maintenance not directly related to any defect covered under this limited warranty. Improper or incorrect installation or repair may void this warranty. The installation of replacement Appliance parts under this limited warranty does not extend the original warranty period. Any repaired or replaced Appliance shall be warranted for the remainder of the original limited warranty term or thirty (30) days after shipment of replacement part, whichever is longer.

Registration Requirements:

This limited warranty is provided in the form of an Extended Limited Warranty and a Base Limited Warranty. The Extended Limited Warranty applies to all Appliances fully registered within sixty (60) days of the installation date. The Base Limited Warranty applies to all Appliances that are fully registered on or after the 61st day beyond the original installation date or any Appliances that are unregistered. To properly register Appliances, the purchaser must complete and submit the warranty card included in the documentation, register via the Anesi APP, or visit: Resources, and click on “Product Registration”.
