Sadly, I am having to write a new review and revoke my earlier review from 2015-2016. Five years and three weeks after they installed my AC unit, it failed, due to a faulty coil (that could only handle so many pounds of pressure that had been increased (by two times) to comply with industry standards, but without fortifying the coil); this added stress in the system, causing multiple ruptures--that leaked ALL the coolant. So basically I now have a $5K fan. This contractor did not file my warranty paperwork with the manufacturer; the "five year" warranty expired just weeks earlier, and the manufacturer chose to ignore / void; it would have been a 10-year warranty, had Frank's done their job and filed my paperwork with the manufacturer. I was crushed. Frank's sons did the work, and Frank had to come out three times to service it to keep it working. I think he knew it would fail, ultimately, and felt bad. The family (Frank and sons) have been out of business since a few years after they installed this unit, for which I paid over $5,200. As a new homeowner without a lot of experience, I thought they were great, but unfortunately, the failed part caused the AC unit to blow warm air. It was a known issue with the part, which is probably why the deal was so agreeable. They left exposed hoses and pipes everywhere, without taping things off. I had to fix a bunch of things that looked awful (by taping them and securing them from hanging from the ceiling and walls). Although they were timely and easy to work with, I've had a broken AC unit for several years, and they're not only no longer in business and unreachable: the unit will cost more to repair than replace. I was utterly grief-stricken over this. Never again with these people. Avoid them. AVOID THEM. read more
