"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."

"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."

"We decided not to go tankless but E&R did a great job installing a new 50 gal Rheem heater. Very quick and clean install. I will use them again in the future."

"Boiler stopped producing hot water. Called in the evening and Mansolf came the next morning. Did diagnostic and ordered parts for repair. Punctual and reliable."

"Great job with the new washer standpipe and utility sink drain and water supply. Thanks!"

"Kenny did an excellent job and I give him 5 stars. I was told by the office staff that the installation of the new water heater (under lifetime warranty but only five years old when it needed replacing) would take up to six hours. The actual work time was closer to two and a half hours, most of the time was taken up waiting for the delivery of the new heater as well as half-way through Kenny left for another two hours, maybe even longer, to pick up an expansion tank. I had been quoted a price of $950 for the installation . After the installation the office called to ask how I wanted to pay I challenged this amount and ended up paying $850 instead. - I very much appreciated that Quinns were able and did install the hot water heater so quickly but felt I was taken advantage of financially."
