These guys are awesome!!! They came out to put in our heating and air system with the crew and all. Poor guys were in our hot attic for a few days but they never complained and were happy to do the job! The guys were very polite and they cleaned up after themselves.
I would definitely recommend Harmonic to family and friends! They are the go to guys for your heating and air!

Thanks Jeremy and Harmonic crew! We are loving the air right now!

Loved them! Our 27 year old furnace kicked the bucket on a Friday, their team was at our house a few hours later! Unfortunately, getting parts for an old furnace is difficult, and costly. We already knew if certain things broke, we'd go for a replacement. Harmonic clearly laid out our pricing options, and answered our questions.

We decided to swap our furnace and ac unit, and harmonic gave us a great price! Everything was swapped out on Monday.

Great company to work with. Thank you for ensuring we were warm and toasty for our last weeks of winter :)

Most positive experience I’ve had from any service contractor in a long long time!!! From estimate to installation it couldn’t have gone smoother. Jeremy sized me down on both a/c and furnace units where other companies didn’t-saving me money! He took his time to explain everything to me. Installers were very professional and did a great job. Liz in the office answered all my questions and was very polite. From what I experienced so far Armstrong products rock.

I moved and haven't been able to work with them. I however was impressed with their work and recommend them when I can

Harmonic did a great job! Quick response on quote, plus they were the best price from over a half dozen quotes I received. Showed up on time (a little early) and tech was very pleasant. Got the job done quickly and done well. Can't say enough about them. Would definitely use them again.

After getting some quotes for a new furnace to replace a 30 year old one, we chose Harmonic to furnish and install a new high efficiency 2-stage unit in our house. Jeremy was very professional and took the time to explain the difference in units on the market and what his personal preferences would be. He didn't try to oversell us on something that wasn't going to add any extra benefit to heating our house. His crew was very accommodating and did a great job installing the unit and making sure everything was done properly. They even stuck around a little longer to explain what they had installed, and even walked us through set up and using our new smart thermostat which they installed. I would definitely recommend for any furnace or AC installations.

Liz, Jeremy and the team at Harmonic are fantastic to work with! Our AC unit for the business went down on one of the hottest days this summer. They had everything lined up and implemented (including the crane to lift the unit!) in very short order. I cannot recommend these guys enough! Great follow through and customer service. Thank you :)

I've purchased both A/C and furnace from Jeremy at Harmonic. He and his associates have been top notch. He's careful to answer completely my questions, gave me options and explained pros and cons on the selections. I was especially impressed when he gave me an option to postpone my installation because so many of the techs were out with the flu and although he himself was feeling well, his kids were sick and he didnt want to get anyone sick. I took the postponement. Very pleased with the service and products

Jeremy was very knowledgeable in properly sizing our HVAC system for our house. The price was very fair compared to other quotes I received. His installers did an excellent job, were on time, professional, and cleaned up before leaving. We opted to install the Reme Halo air purification system, which I highly recommend, for just a small upgrade to your system. Great company, and would use again without hesitation!

Harmonic is a locally owned business with an owner who adds a personal touch and value to the entire experience. I got a quote from a large national vendor and not only did Harmonic meet the quote, he explained why there was something wrong and fixed it improving my efficiency 20%! Call them, you won't be disappointed.
