" On time, honest, respectful, and good prices. I will use Harmonic from now on. Dan explained everything he did. I was scheduled and had heat in less than 24 hours of my calling them. They also use face masks, gloves, and shoe covers, and disinfect all surfaces they touch as the are exiting the home as recommended in light of the current Pandemic. Great company!"

" Harmonic is now my GO TO company for ANY HVAC service. Daniel was my service tech. Friendly and courteous. Performed a minor repair to save me over $1300 as opposed to another company that wanted to replace a bunch of parts and charge a fortune. Icing on the cake - Daniel wiped off the exterior door handle with sanitized wipes as he left. If you need and HVAC work, don't waste time with any other company. Call Harmonic. You won't be disappointed. Even the women who scheduled the appt was friendly and positive. I wish these guys worked with more than HVAC.
Thanks Harmonic. You were awesome."
