In addition, he was also training an intern so it was fascinating to hear him explain things during the checkup to the intern, he a good teacher. We have relied on Fahnestock for our HVAC, plumbing and electric for over 15 years, and true to every visit we have had, they have outstanding employees, we can add Jack to the list.

I'm using an ancient system that may have been original with the house, (50s) and they've kept it running with only minor repairs and with regular maintenance.

Was given a runaround by this new owner named J who claims he's really not the owner but he actually is and I think he's also the receptionist and the technician. He he's nice enough, but absolutely everything that comes out of his mouth you cannot trust. He never showed up for his first appointment and did not even call and I called the next day and said where are you and then he decided to show up. He took two hours to try to diagnose a compressor problem. He does not return phone calls, and he lies about who is still working for the company and about people who left the company saying that they retired when they in fact have not. One lie after another and now we are going to have to pay labor to fix a two year-old expensive unit so much for the warranty and standing behind your business. I wouldn't want them out even if it was free though because I don't think they know a thing that they're doing.

The only reason this is not a perfect review was the disconnect between the quote and the final bill, I was told by an office employee when we scheduled the work that the blower motor could be as low as $200 (and online it was readily available between $150 and $200 delivered so this seemed in line), but final part charge was about $650 (over $750 total with labor). Sure they have to pick it up locally, and the middleman parts supplier needs to make a profit, but quadrupling a $175 part price seems like nothing short of gouging. If you decide to hire this company, my advice is to get a written estimate before you commit to doing the work, And maybe get a comparison while you're at it.
