"Repairs were excellent and thorough "even well documented". The tech found units low on coolant. He identified and repaired multiple refrigerant leak points. I have dealt with many HVAC contractors over the years and Freedom Air Mechanical is one of the best. I highly recommend."

"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 chose them because they had the highest number ( and score) of reviews, but after the service was provided I believe those reviews were fabricated. I am a new home owner and decided to try your services. I did not know much about duct or vent cleaning but after what I saw yesterday I decided to do some research online and that is when I realized I did not receive the services I thought I was paying for. Only 1 technician came with a small shop vacuum and a brush, and he was not able to do most of the work because. 1. We had Fibreglass ducts and he said his equipment was not suitable to clean this type of duct and that it would damage it. So he only "vacuumed" the area that his arms could get to, and did not examine the vent for damage or recommend any way to clean or fix the fiberglass. 2. He did not want to take the vent covers off the ceiling because he said he did not want to damage the sheetrock, so I'm not sure how he cleaned them. I think he only sprayed air into and around the vent 3. He didn't have any air filters with him, so I had to go out and try to buy them. They did not have the size I needed so I spent 1 hr driving around looking for them and could not see what he was doing at home. 4. They did not seal any of the vents nor did they have a negative pressure machine. He did not hook up to the main vent and told me he accessed it with a brush through an intake, which means that they did not fully take out all the dust from the main feeder. At first I was ok with his explanation, fine but then after doing research I realized that all he did was stick a brush in the room vent but did not seal the whole system, nor did he take off and clean the main duct. 5. He said he cleaned the dryer vent from Inside and Outside but I did not see any signs of him going outside as it was raining and he would have had to get the machine wet. 6. He had no other equipment other than a shop vacuum with a 4 inch hose. I'm not sure how deep he was able to get with that into the dryer vent. I really feel as if the work performed was not done correctly, and my ignorance was partly to blame. This company certainly did not have the right equipment to do the job and they didn't even use the correct procedure to seal the system to create a vacuum. This was definitely more of a $300 dollar job at most and not $600 dollars like they charged me."

"Mitchell was very professional and great at the work he’s done on my 2 homes. I’ve had 2 bathroom remodels. Funace and hot water heater replaced. Put an expansion water tank on one of my homes. Hooked up my water for my new refrigerator and dishwasher. Have not had any issues with his work. Highly recommend."

"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."

"Our furnace broke during one very cold night during January 2014.  They tried their best to diagnose the issue over the phone, but came to look once it was clear that it was not a small issue.  They diagnosed the problem quickly, but we had to wait about four days while a part arrived.  They kept us informed, and also kept us warm with space heaters (that worked surprisingly well).  
When the water overflow tank was daignosed as broken, again they were very responsive and good about keeping us informed about when they could fix it.
I don't really know if the price they charged was good or not - we really did not take the time to shop around."
