" Nate is a total Rock Star!!!!!!
He was very knowledgeable, fast, and was able to fix problems when other HVAC companies told me it could not be done.
I highly recommend Harmonic to anyone in the future. "

"Tony was on time and professional. A couple days after service I noticed an issue and before I could call about it Liz called me. I was scheduled for a follow up that day and the problem was taken care of to my total satisfaction. I have always had excellent service from everyone and highly recommend to anyone looking for a heating or cooling referral."
