"I had AC Dave preform three jobs for me over the past few years. (1) New ducts a few years ago. (2) Installed a mini-split heat pump in master bedroom this year. (3) Then a few months later I had him remove my old Central AC and replace it with an 18 SEER heat pump and new coil, all the while leaving my old furnace in place as a back up. Dave and his guys did a great job on all three projects, completing each one in a day. Highly recommended."

I received a quote to install a mini split air conditioner/heat pump and we were overjoyed of the quality of work we received. They showed up on time and installed the system with ease. The install Manager â Deanâ was a true leader and got everything needed accomplished. I would recommend Dean and crew to anyone needing quality service. Thank you again for everything.
