Get matched with top tankless water heater installers in Killingworth, 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!"

"Mike was prompt in providing a quote, and the quote was very reasonable. I had to have a new hot water heater installed, and he worked with a vendor to get me the best one for a reasonable price, delivered. He came in, observed COVID-19 protocols with no issues, and did the work for the price he quoted. I am incredibly pleased with his service and will be using him again."

"They were timely, clean, worked great with the water company, professional, price was fair. Very nice and very genuine."

"The representative came on time and listened carefully to my thoughts of a split ductless system. He suggested full house central air and showed me how it could be done, have ducts i stalled and cost less than a ductless system. His experience of over 20 years as a technician as well gave me a lot of confidence. He made a general proposal and came back in a few days for my convenience and I signed the contract. The duct crew finished in one day and were careful, explained things and left no mess. Then the ac was installed and tested in one day. Again polite, clearly communicated. Once the system started up late spring I am so glad I did this! No more noise from room ac, no shutting doors to keep one room cool. The humidity is normal and makes a huge positive difference. I highly recommend HARP. I switched my heating system to them as well after my experience with the AC i stall. Thank you HARP!"

"Derrick the plumber was friendly courteous and very knowledgeable. He was eager to talk and share his knowledge of the project and the business in general. (Some of these people you can't get two words out of and when you do you wish you hadn't). He did the best he could on an old shower set-up and it's up and running again. I'm very pleased and would recomend them instantly to anyone in need of the service. The office was also very on top of things as to appointments and scheduling. Again I would recomend them highly!"

"Technician was on time, polite and courteous, knowledgeable and resolved our heating issue quickly."
