Get matched with top tankless water heater installers in Greens-farms, CT

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Discovered our 6 yo gas water heater developed a leak. Decided to call on these guys as they provide the annual maintenance for our A/C and furnace. Called early AM and they were able to have a service technician on-site within 3 hours. After inspecting the tank and finding the source, the technician proposed the replacement options. Although most seem costly, the technician did a great job of explaining the work involved and how much time it would take. After doing some research, I went with these guys....and everything went to plan. Was able to schedule an appointment that worked for our schedule. The same technician came back out with another colleague. The entire job took about 5 hours. They answered all my questions. And they worked very neat. Yeah, they weren't the 'cheapest.' But, they corrected some previous issues, worked efficiently and completed the job correctly and in relatively quick time. They new exactly what to do and how to do it. Very good experience. Thanks, SILA team!"

"Comfort Masters did an excellent and very thorough job installing a new hot water heater and repairing some old plumbing disasters in our new home! Chris was polite and professional, I recommend Comfort Masters without hesitation. Very reasonable pricing as well."

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"Installers arrived on time and everything went smoothly. Had to have them back a couple of times to balance out the rooms. Some were not cooling properly. After the third time they finally got it right. First technician was a younger guy who was not keen on going into the attic since it was hot up there. He didn't know what he was doing. Second guy the same. Third guy was an older tech that I made a comment about it being hot in the attic and his comment was that this was his job no matter the conditions. Very professional. Should have sent him the first time."

"Water heater broke Friday, had new one installed by Monday afternoon."

"Very knowledgeable team that helped us decide between a tankless and high-efficiency tanked water heater to replace two old water heaters in the home we purchased. Team performed all work with no visible modification to existing home structures/walls/ceilings and all work was completed in a day. The installer even stayed a bit longer to instruct us on maintenance and usage of the unit considering we are new home owners which was very much appreciated."
