" On time, honest, respectful, and good prices. I will use Harmonic from now on. Dan explained everything he did. I was scheduled and had heat in less than 24 hours of my calling them. They also use face masks, gloves, and shoe covers, and disinfect all surfaces they touch as the are exiting the home as recommended in light of the current Pandemic. Great company!"

" We woke up this morning and our heater was not working. Since the owner lives in our neighborhood we thought we call them first. Liz picked up the phone and was very polite and even called back to say she was going to redirect someone to make us a priority. She did ask if the switch was turned on the heater which I did test and asked if it was the switch it would kick on right away and she told me yes it should. Seems like my 2 year old son did flip the switch off on our furnace and my furnace takes about 15-20 seconds to register that it needs to kick on. Brandon the service tech figured out in the first 30 second of looking at it that it was the switch but then said he would watch it for the first 7 mins to make sure everything was working. Since it was a simple fix I figured I would go ahead and make their visit worth it and said to go ahead and do a cleaning on my furnace and Brandon did that as well. Once he was done he advised that the igniter was worn and would need to be replace in the near future. I told him that he could go ahead and replace that as well. He did a great job in the install and was very professional only thing I was kind of surprised by was the cost. While I knew I was paying for cleaning and replacing the igniter I was surprised to find out I was being charged a $55 service fee and a $79 diagnostic fee. Seem like a bit much for him to flip a switch and watch it run for 7 mins. I had a similar situation a few years back and four season waive the charges and only charges me a cleaning fee. I didn't argue the cost as they did move me up to get it fixed quicker. All in all they were very polite and professional but was surprised by their additional charges."
