You are right I am not a expert in heating and cooling that is not my profession. I hired another company turns out there was a leak in the fiberglass tape that caused the issue. Ron's heating blamed the builders saying not enough insulation or etc. Well you're wrong. You guys come to my house for 10 minutes . Yes it's on camera you can say different but it shows when you stepped in the doors and drove off. Total 12 minutes. You guys want to charge me a diagnostic fee FOR WHAT? You guys didn't diagnostic the issue another company did within 30 minutes. Get a second opinion before hiring this company because they are a one sided company and that side only Benefits them. I have my newborn room with improper heat coming into the room. It's 61 degrees when the house is set to 70 degrees and they blame the builders when it was due to their issue that they didn't even diagnose another company did. JOKE of a company. I tried paying the diagnostic fee that I honestly shouldn't because they rushed and didn't even spend the time to figure out the cause. They wanted to charge me a 3% fee for a debit card. Then they tried to charging me for a visit the the prior owner did and never collected on me. The owner wife was trying to pull a fast one on me then said ohh sorry I didn't realize it was a different name. Luckily I asked my total before providing my debit card number

Because we were displaced, H.E.R.O. moved us up in the list and got us a top of the line until (the last a local supplier had) and installed it quickly so the cleanup crew could get us back in. They even recommended a plumber, Steve Clark, who has given us similar service. We are now waiting on the thaw to get the air conditioner portion installed which is sitting in their facility. The unit is wifi capable and will contact H.E.R.O. if a problem develops. We joke with friends that our thermostat gets HBO and Cinemax. We have and will continue to recommend them without hesitation or reservation.

Also checked my capacitor and suggested I replaced it due to it not running at full compacity which I did(obvious up charge). They gave me quotes for a few different options to do like replacing whole unit, cleaning ducts, replacing fan etc. I said I'll have to talk it over. Called a couple weeks later to find out the price again. They wanted to charge me another service fee so they could come out again to tell me the quotes from prior visit. On top of another service fee for the service when they do the replacing of part. So up to 3-4 service fees for one issue that they did not resolve. At $100 dollars a pop not including anything else.

I genuinely believe the company has a lot of integrity when it comes to service. Just talking to the employees, you can tell how much they really like working for the company. I have had the occasion to call maybe three or four times for a variety of services. Not once did I feel like I was being taken advantage of, even when they responded to an emergency. I do not believe this to be the case with many other businesses that specialize in the same services. Highly recommended!!

Have recommended him to other ls who've all been pleased with his ability to get their repairs done quickly & more importantly done RIGHT. I've had a furnace that has needed repairs multiple times since 2007. It finally took it's last breath recently although Chris tried to his best to get it going. Chris helped me decide which new furnace to get ordered after I asked him which furnace would he get. He explained the choices & a decision was made. The furnace arrived in 2 days & was installed in an afternoon. Furnace works perfectly!! For a reasonable price too I might add!! You don't need ro look any further for a great HVAC contractor. His work ethic is rare. Thank you so much for all the help!

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.

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!
