Warranty Info

Warranties on mini split air conditioners only include parts and do not include labor. The licensed HVAC Technician who installs your air conditioner should always provide you with a labor warranty (preferably for at least a full year to compliment the manufacturers' parts warranty).

AJ Madison will only finalize a Mini Split (Ductless Split System) purchase with an authorized HVAC Technician. AJ Madison recommends the installation of a mini-split system to be performed by a trained and qualified HVAC technician with the proper knowledge and background. A trained technician will be able to judge the best location for the air handling (evaporator) unit and also the correct size for the area the unit will heat and/or cool. For assistance with all your technical needs please contact our technical department at hvactechsupport@ajmadison.com.

Should you experience an issue during the installation or the initial startup of a unit please do not contact the manufacturer. You should have the technician that installed your system contact either AJ Madison or the manufacturer. We cannot accept any service or warranty calls from anyone but a licensed HVAC technician. We have a full technical support team available to help you throughout the installation process.

AJ Madison, Inc. cannot be held liable for improper installation and operation of any product purchased from our company. Should a warranty issue arise in which parts will need to be replaced, an installation receipt will be required along with your AJ Madison sales receipt. Failure to provide a receipt or invoice may result in the warranty not being honored.
