No issues with the technician would did spend a bit of time taking the oven apart. He tested the control board and said it was the issue, collected my service fee, then an hour later sent an estimate for more than the price I paid for the oven two years ago. I can look at the part online and they are wanting to charge double, plus $500 for roughly the same labor that they just spent doing for a $65 service fee. So while they were quick to respond and nice enough... I'm still up a creek with less money and more wasted time.

Amazing customer service. Our service provider of choice for ANYTHING plumbing and heating related…read more Taryn is super responsive for scheduling. Brett and Cam have been to our 30yo home so many times for repairs that we don't even have to show them where to go. They have repaired the humidifier, the sump pump, and leaking bathroom tubs (twice when the wall repair guy messed up), and replaced an old water heater with a tankless water heater. Their assessments are above quick concise and easy to understand. Their scheduling is the best in the business and their customer service is what I strive for in my own business. We will keep them on speed dial (is there even such a thing anymore ) for any future plumbing needs.

Prices are fair, maybe a little more than the competition for some things, but I feel the quality of work is absolutely worth it anyways. Most times the work is scheduled very fast, and during an emergency, he came out within the hour. Their service plan is also extremely reasonable and absolutely worth it. I appreciate that Taryn schedules and responds via email with me all the time since it's way more convenient for me personally, and Brett always calls before he makes his way over. Best plumbing team ever!

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!

The emergency call cost over $140, heater wasn't working. Furnace wasn't cleaned, technician said…read moreit was either a bad ground wire or a circuit board. Said he put in a new wire (although had no confidence that was the problem) and was working now but that it was really random. So didn't know if it would be fixed and ordered a circuit board. He seemed very unsure. I've had my furnace serviced before (by another company) so I'm not a newbie. A cleaning wasn't ruled out but more expensive fixes were immediately tried, like he had no clue but would try, I don't know... I called another company because I felt this was obviously poor service, maybe even a scam. Ans as I suspected it needed to be cleaned and a faulty sensor (a minor repair) was put in. And at a very reasonable price. I was left with the impression that I was being taken advantage by Charles McDuffee Co. or that an untrained or poorly trained person came. I will never use McDuffy for anything. EVER. Definitely the worst service repair I've ever experienced as a home owner for over 40 years!

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.

This shows their dedication to customer satisfaction and making sure the customer has the best product to address their needs. Highly recommend them.

I hired them to correct the wiring issue after installing new zone values. It was a simple job and…read morethe boiler worked perfectly for last season. All they were supposed to do was, just do it exactly as how the other boiler was set up. They took 5 visits to fix the simple wiring and slapped me with a $2,550 bill. First visit: 2 guys came and removed old wiring and installed new wiring. Obviously, they have no idea what to do. Complained about boiler transformer, thermostats, and new zone values and gave up and left. Second visit: They sent a different guy adjusted some wiring and left. Guess what, that only worked for one zone and others have no heat. Third visit: Came again and complained about thermostats installed by first visit guys and replaced them and left. No heat again in other apartments Forth visit: Same story....no heat Fifth visit: This time I was frustrated and told them explicitly, that your wiring was wrong and just followed how exactly was done in another boiler. Finally followed my directions and corrected the wiring. They were supposed to do it on day one in less than an hour. Basically, they had no clue how to fix it and still took the job. I have been telling from day one, that you guys are doing the wiring wrong. They completely ignored me and made 5 visits to fix a simple wiring. This boiler serves heat for 5 apartments. It means 25 calls to my tenants to test the heating. Boilers are pretty simple technology and they work flawlessly. Just to slap me with the bill, they changed unnecessarily so many things for the perfectly working boiler. I strongly suggest staying away from this company if you would like to protect your money and equipment. I regret hiring them based on Goolge's reviews. Hope this saves money and time for someone.
