    DeLong Air did an excellent job fixing my AC this month. The technician, Kevin Vest, did a great job of explaining what was broken, how he'd fix it, and was upfront the entire time about costs. They were quick to service as well, with my placing the call Friday afternoon and them arriving Monday morning.

    Highly recommend if you need HVAC performed.

    Wow, when John Seiber, General Manager of Delong Air, told me that the new HVAC system would be whisper quiet, I didn’t believe him. I was wrong not to believe him; the HVAC system he installed for me is exceptionally quiet. You can stand right next to the air conditioner and barely hear it, same goes for furnace blower. I couldn’t be happier with the system. Carson and Caiden, John’s installers, were prompt, courteous and very competent. They installed the equipment, tested it, gave me tips on how to use the new thermostat, cleaned up, all in one day. I highly recommend Delong Air.

    I use Delong Air for both residential and commercial. They have installed complete new systems and have provided on-going routine maintenance. They have great technicians that care about what they do and provide honest evaluations of the equipment and excellent service.
