"This was among the best experiences I have had with any third-party contractor, period. We did an expensive central A/C replacement. Seashore Comfort was knowledgeable, responsive, professional and technically proficient. We needed a 20-year old A/C unit replaced. I called four area HVAC specialists and almost didn't call Seashore because they had relatively few online reviews (although the ones they did have were positive). Turns out the company was started relatively recently by a veteran tech and his wife, who worked locally for a couple of decades. Every aspect of this project was impressive - from the front-office communication to the quoting process to the technical description of what are options were to the quality and craftsmanship of the install. Furthermore, I _almost_ went with a different quote from the local "giant" and that would have been a huge mistake. It took quite a bit of technical research and education on my part but what that company was proposing would not have been the best choice of solution for our application. That would have been a costly, long-term mistake. So, in short, this is a scrappy young company with the all the benefit of experience of a much older company. Proceed without reservation."

"I hired them because I just moved into a house that had 5 cats and I have a bad cat allergy. The team came in, worked hard, efficiently and were very thorough. They also fixed/adjusted a few small odds and ends in my system at no additional cost. A nice team and very friendly."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"Scheduling was challenging. On the first attempt, the service guy never arrived. When I called, the scheduler said there was some computer error, apologized, and rescheduled. On the second attempt, the guy came and did the service, then recommended having the expansion tank replaced. I was supposed to get a call to schedule the follow-up service, but never did. I called a few times and left a message, eventually getting a callback from someone who was able to schedule the service. Once again, the first attempt was a flop. They sent out a heating technician, not a plumber, to replace the expansion tank, which he was not certified to do...and he arrived late. On the second attempt, the plumber arrived on-time. He was very professional, efficient, and did great quality work. He made a recommendation for some other plumbing work after I asked him about an issue we had been having. He told me to call the company to schedule the work. Once again, I struggled to even get the service scheduled. This time, I gave up after 3 or 4 tries. I'll be contacting another plumber to get the work done at some point."
