"DO NOT HIRE FOR HVAC. Cotti Johnson has been the single worst contractor I have ever dealt with to date. If you have a simple HVAC repair, they may be able to do it but it's a gamble. If you have a large HVAC related work to be done, do yourself a favor and hire a company that understands the equipment they're dealing with. Where to start... I hired Cotti-Johnson to replace my old oil boiler with a modern heat pump system as the main source of heat for my house. Thomas Kelly, who was the initial person that came and made recommendations on the replacement system, should not be in the business of recommending heating systems to people. First of all, there's no heat load calculation of any kind, which is the first red flag but I didn't know any better at the time. They simply guess based on the size of the house without knowing a single thing about insulation or any other factor. Second mistake was recommending a single indoor head for an entire first floor that's separated by stairs in the middle of it. My initial concern with this was dismissed by Thomas who simply said "just give it a try!" Unfortunately, we're now stuck in a position where we can not remove the old boiler because the new system simply can not heat our first floor evenly. We have hot side and cold side and unfortunately our dining room is now permanently cold. It has been months of unanswered calls and emails and numerous back and forth to come up with a solution with still no end in sight. They do not return calls. Third mistake was installation. It took weeks to convince Cotti-Johnson and countless ignored calls and emails to get them to fix a mistake they made with the original install. Even then, they had to make multiple trips to finally realize they didn't account for line lengths accurately and undercharged the system. They finally did admit this and properly charged the system. They simply did not know how to deal with the equipment they're installing. I had to ask for proof of exactly how much refrigerant was being added in order for them finally do a proper calculation and add correct amount of refrigerant. Hire a diamond certified contractor if you want a Mitsubishi system and do not want to deal with these kind of amateur mistakes. Even after they finally did charge it to seemingly proper levels, they never installed back the brass screw caps for the outdoor unit or put the cover back on all the way. All around careless and amateur work. To add more insult to injury, I have been trying to get in touch with Cotti-Johnson for over 3 months for correcting inspection results and so far all of my calls and emails have been ignored. Learn from my mistakes and avoid this company at all costs."
