  Harmonic is not just good, they are great! I should have reviewed them sooner and I rarely do these things, but they are sincerely great. They provided us with a great price through negotiation; which is rare these days. They were recommended to me by real estate agents, I took that as a positive sign for lasting service. The bottom line is; they have just been around longer than most of the other guys. A lot of new companies come along with good prices and mediocre service. These guys are great at everything and detail orientated: when I told them about the dirt left on my neighbors job they cleaned it up (I honestly didn’t care, but I thought the next customer might). The owner personally came out to my home (even at the beginning of COVID), he was a straight shooter and I love that. Also, Liz is awesome on the phone and always available!

  Thanks for the great 5-star review. We try to provide the best customer service possible. It’s important to us that we met your expectations. Remember to protect your investment with our signature “Rock*Star” HVAC Maintenance Plan so you can also save money on the annual furnace and AC clean and check / tune-ups. Enjoy the season!

  I first used Harmonic a few years ago after having trouble with a newer furnace bought from and installed by another company who advertises a lot on TV and Radio. Jeremy and Harmonic came right out and diagnosed and resolved the issue at a very fair price. While there they also pointed out some flaws in the original installation and basically did a reinstall for nothing extra and the difference in appearance and performance of the furnace was noticeable. Since that first visit I have used Harmonic for regular maintenance and a new Air and new Furnace. Every time they come out they are prompt, and professional, providing excellent service at a very fair price. Highly recommended!

  Thanks Bill. There are a LOT of HVAC companies out there to choose from for AC & Furnace repairs or replacement. We truly enjoy serving our neighbors and helping them with their heating and air conditioning maintenance. We want everyone to be comfortable in their own home, and help them save as much money as possible along the way. Thanks for trusting your Furnace & AC services to Harmonic. Enjoy the season.

  Harmonic has been providing us with preventative maintenance on our heating & air conditioning system as well as our water heater. Always professional and trustworthy. They helped nurse our systems until they were no longer reliable and we felt confident in giving them our business when replacing all 3 units.

  Thanks for the 5 stars. Remember to tell friends and family about our 3 Rock*Star maintenance plans to help avoid those expensive no-heat furnace calls in the winter and no AC calls in the summer. Our Rock*Star VIP plan also takes care of that Hot Water Heater. It’s the best way to keep the family comfortable year round.
