"I had two new Air Conditioners installed by Harmonic recently and am very pleased with every aspect of the process. What is outstanding is the responsiveness, attention to detail and professionalism of every individual I interacted with at Harmonic. They were great at explaining and answering any questions I had. The scheduling was easy, the technicians arrived promptly, they completed the work and went over what they did, left the places clean. Shoutout to Liz who has been fantastic throughout the process! Highly recommend Harmonic to anyone, I know I will continue to use them."

"Two nights ago, our air conditioner stopped working. Before 7 am yesterday, I had researched and contacted three HVAC companies in the area that all had five-star ratings, resolving to go with the company that contacted me first. I received a call from Liz at Harmonic and arranged service for later the same day. [Important to note that the next company called four hours later, and the third one, five hours later] Daniel arrived right on time and start to finish was amazing. Always the consummate professional, he was open and honest every step of the way, as the problem was a bit of a diagnostic nightmare. He was able to get the unit up and running and at a cost much lower than I anticipated. Last evening, I had a follow-up question which I submitted by email through the company website and within three minutes Jeremy, the owner, was on the phone answering my question! Talk about service! I completely trusted everyone that I dealt with..…Liz, Daniel and Jeremy, and I have no need to look elsewhere for HVAC services, ever. "

"Extremely quick and excellent service. Thankyou to Liz for her care.
The technician was very thorough and I was able to make a good decision to replace the units involved. He took time to explain and show me in details the problems involved. He also explained and answered all my questions involving the new units to be installed. This should be done within two weeks as units had to be ordered. I have been a customer of harmonic since I moved here 5 years ago. Extremely satisfied. Thankyou. Ellen Fischer"

"Thanks for the great Review Ellen. Sorry for the wait on that air handler, they are very specific, so our distributor orders them from the factory. We've been happy to serve you and the others at Park Ave. We appreciate you, and we'll see you soon to get that AC and Air Handler swapped out, so that your summer will be a bit more comfortable. "
