Get matched with top tankless water heater installers in West Haven, CT

"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Professional, courteous, responsive, and fair price. I highly recommend and will use them again. E and R Plumbing was 1 of 3 companies recommended to me by HomeAdvisor and I contacted them because they had the best reviews. Almost immediately, I received a call from Rich and while he was on the phone, he asked me to send over pictures of my 16 year old Water Heater Tank that needed to be replaced. He quoted me a fair price for both a Tank and Tankless water heater and I decided to go Tankless. Rich and two colleagues showed up the next morning, removed the old Water Heater Tank and built out a plywood mount to install a new tankless water heater directly behind where the old tank was, taking up less space. Rich and his colleagues completed the job exactly as described, and Rich called later that afternoon to make sure everything was running great!"

"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."

"Plumber was very knowledgeable and professional. He found the problem and fixed it right away. I also had other issues going on that he was able to address. I highly recommend this company"

"Professional, thorough and meticulous . Strongly recommend Joey and his team at Precise HVAC Services"

"Mike and Todd worked quickly and installed a new water heater for a great rate. Was easy to communicate with during the entire process. Definitely recommend."
