    Needed to have some heating work done at my place of business, after our heating unit stopped…read moreblowing warm air. It was quickly becoming an issue for my employees, and if we didn't get it fixed soon, we would have to consider canceling work. I called one company who came out, and then told me that I really just needed to replace the furnace, and gave me prices to do that. I reached out to R.J. O'Neil for a second opinion, and boy am I glad that I did. They initially said they couldn't make it till the following AM, but an hour or so later I received a call that their technician had finished a job earlier than expected and could make it out today. Great News!! The technician came out, and after troubleshooting, found out that it was a processing board that needed to be replaced. He ran back to the shop to grab one and made the switch. We had heat back up and running by the end of the day. Being a business owner, it is always nice when you can find a trustworthy company that isn't just out to make a quick buck, but to foster a business relationship. I will definitely use them again in the future for my business and personal HVAC and plumbing needs. I also will continue to refer them to others. A big thanks to the team for getting our heat working so fast.

    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!
