Harmonic Heating and Air Conditioning is the BEST!!! Our AC…read moredied and after another company told us that our unit could not be repaired and had to be replaced ($6,000), we contacted Harmonic for a second opinion. Daniel the service technician opened the unit up and tested everything. He took the time to explain what he was doing and why. He discovered a bare wire that had been chewed (possibly by a mouse) and was touching the metal housing which tripped the circuit breaker. Daniel replaced the wire and the unit is working perfectly. The honesty and integrity of this company is refreshing. We will not hesitate to use them again and recommend them to all our friends.

Stay away from this business! My entire cooling and heating system was left in an inoperable state…read more I called for a diagnostic of the air conditioner today because cool air isn't coming from the vents. I was told the diagnostic would cost $149. I asked to be informed of any repairs that had to be done. Technician checked the system and recommended replacing unit. We discussed replacement unit and cost. I was ready to pay deposit. In the next 10 minutes I was told that the model I selected is old and not available. New model costs $1000 more. I asked for a proposal to decide later. Technician told me that the visit costs $396. He said that he fixed air conditioner that was not working. He never told me that he is fixing anything. Through our the visit it looked like he was figuring out the problem. I talked to the owner and we agreed that any repairs that were done will be undone so that I do not have to pay for repairs. Then the technician removed all the wires from the board making both heat and fan unusable. He did not just undo the "repairs", but made entire system unusable including fan and heat which were working before his visit. See the photos to show what was done!

Mike was more than prompt to come to my house, give me the best estimate, and educate me on the process. He was available next day to install. He and his assistant were on time, done faster than estimated, cleaned up, and confirmed my satisfaction. I will skip calling my regular go to and go with him in the future. Great value and great service. I'd strongly recommend calling him.

I needed a humidifier installed in new construction home. I'm extremely pleased with my experience…read more They explained things patiently and thoroughly. When they came for the install, they informed me that the original humidifier was not the best fit. Rather than installing it just to get the job done they paused. They recommended a different option that was actually a lower cost and that they would have to come a different time to install it. This shows their dedication to customer satisfaction and making sure the customer has the best product to address their needs. Highly recommend them.

He was over quickly and had my furnace up and running. I would, also, say he is professional and friendly. I would definitely recommend him to anyone. I've seen a couple of low ratings, but they were for services other than HVAC. Based on my experience and that it is Jerry's Heating and Cooling it makes me wonder of those people are putting their review on the wrong business. On Google Jerry's Heating and Cooling has 100% 5 star ratings with 138 reviews.

Discovered I didn't have ladders to reach the areas needed nor was I warm & fuzzy about going up to the roof peak either. Enter Jerry, I saw on yelp that he was recommended, he came out same day, was very personable , did a nice job, price was reasonable. I also discovered that thru discussion that Jerry and I had a few mutual acquaintances and some things in common. Nice guy, I do recommend him & its highly likely he will take care of ur issue on the same day as his van is well stocked w/ things he needs to do the job on the spot.
