Make Yourself Comfortable

Accurate design, install, and service

Talk to an Expert

Correctly sizing and mounting an indoor air handler, the wall- or ceiling-hung unit, or ductwork for a ducted system, is vital to the system’s proper operation. This is where a Diamond Contractor’s specialized training comes in. The difference between a passable and perfect install often comes down to your contractor’s knowledge of the technology and experience with ductless installations.

One of the many perks of hiring a Diamond Contractor is that you’ll receive up to a 12-year product warranty, the most aggressive in the industry. In the case of our Zoned Comfort Solutions®, a standard warranty is fives years for the parts and seven years for the compressor. However, by partnering with a Diamond Contractor, the parts and compressor are warranted for 12 years each as long as they are installed in a single-family home and registered within 90 days from installation. See the product warranty statement for more details. Obtaining a comprehensive warranty not only protects you and your investment but also the comfort of your home.
