Get matched with top tankless water heater installers in Branford, CT

"Bruce and Bill of Williams and Associates Mechanical Contracting recently removed and replaced my 18 year old oil fired boiler and added an indirect fired water heater. I had been saving for this project for over a year and had been geeking out in my avid research (Thanks Internet!) of products available, reviews and costs, as well as the reputation and reliability of local heating and plumbing contractors. I knew what I wanted, I just needed to stay within my budget and find a contractor I could trust. It is therefore, my pleasure to let others know, on the same web review sites that I referred to, how overwhelming pleased I am to have worked with Bruce Williams and his team. They skillfully removed and installed the heating system in a day, took pride in their work and took the time to explain the new system and to fully answer all my questions. Bruce and Bill clearly like what they do for a living, have great people skills and work very well together. I was able to get the very best of products and still come well under budget. I cannot thank these guys enough! Honest, Professional and Reliable! My dusty, unfinished basement with my new Viessmann boiler, Carlin burner and HTP indirect fired water heater is now my favorite part of the house!"

"Yes, one day install conversion from tank electric to tankless gas with water softener"

"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!"
