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!

I've used Jerry twice now and have been very happy. He answers his phone and responds quickly. I…read moreneeded service on a Sunday morning with no heat. 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.

Top tier professionalism, incredibly knowledgeable, solution oriented, efficient, communicative and kind. After struggling to get a response with another company we tried to work with, SRG came in and saved the day. They showed up the day we called, came back the next day and had everything completed within the time frame they promised. They worked long hours in 90 degree heat and have done check ups on the unit and phone calls afterwards as well. We plan to use them for all of our HVAC needs. On top of all this they were fairly priced and had great options. I couldn't recommend this company more. Thank you all- Sal, Hector, Jesus, Brian, Isabelle and everyone else who came through to get the project done on time.

I did not have an issue with their interaction or basic work. I felt comfortable with them being in my house when I was not home or when it was only myself and the workers.

Bob comes over approx twice a year to do a quick once-over and change my filter, which reminds me I need to call him. I definitely reccomend his business for your HVAC needs.

Talked to Jim and he was nice at first until he was supposed to come for the quote and something I said made him thinking I was getting the job quotted by more than one person. I wasn't getting multiple quotes, in fact I was having a hard time finding anyone who actually dealt with boilers. He specifically said he wasn't interested in coming to give a quote if others were involved and when I tried to tell there weren't any others he basically hung up on me. Called him back immediately 2x and left messages with 0 response. Completely unprofessional. If I was actually bidding the job out (which I wasn't) only someone with something to hide would be that concerned so be wary of any quote you get from these guys. Crazy shady and frankly glad we found someone else ‐‐------------------ Jim, in response to your reply you should check your messages again.
