Lennox Premier Dealer

To receive status as a Dave Lennox Premier Dealer, Jett's Heating & Air Inc. in Crystal Lake was trained and is routinely independently evaluated to ensure we offer an unmatched level of customer service. We’ve partnered with Lennox®, a leading name in home comfort, to carry some of the best heating and cooling products in the industry. We sustain our Dave Lennox Premier Dealer status by participating in an independent Customer Review program. The program encourages customers provide honest feedback and ratings on the quality of our service and keeps us accountable for performing high quality work and customer service at all times.
