Get matched with top tankless water heater repair pros in North 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!"

"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."

"Extremely helpful and professional. Made sure my warranty on water heater was covered. Did a great job!"

"They were very professional, showed up time. They did a great job and were very fast--did it in a timely manner. I have hot water now, so I am very happy."

"I received a call back promptly. Tom couldn t have been more helpful to me from walking me through shutting the water and the electricity to my water heater off. He gave me a fair deal on a new water heater made me the first appointment of the day because of having my son in the house and came promptly on time and finished the job very quickly. I really appreciate everything he did for my family and would recommend him to anyone."

"He was very knowledgeable and gave me some advice on how to avoid future problems. He was also on time and the service was done fairly quickly. He took the time to make sure all repair needed was done correctly and assured me if any problems were to occur he would be back to fix."

"I rated them B for responsiveness because the first time I called I was told they would call back and they did not. As you would expect the price was too high. They ended up tightening a union of pipes and testing to see if it leaked. The first time it was tightened, it did leak and they went to replace the part. A second tech tightened it further, retested and it did not leak.Not sure why the first person didn't tighten further. So the question remains; is the problem solved. We will see when the heating season begins. The techs were young, personable and seemed knowledgeable and willing to answer all my questions. They spent over two hours here, some of it waiting to get the heating up for testing. Had a $50.00 coupon or the cost would have been over $400."

"The servicemen were exceptionally polite, knowledgeable and professional. They diagnosed a long standing problem that other plumbers did not and fixed it right then and there. I thought the price for putting in the new vent on the pump was great ($475). $200 for cleaning out the shower drain (full of hair visible to the eye after they popped the cover to show me) was a little high. But I would definitely hire again if needed. Thank you!"

"Larry, contacted me within minutes of me entering data on the site. He explained the replacement options and installed the new water heater the same day. I will also it was the Friday of a holiday weekend....so kudos!!!!"
