"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."

"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."

"Michael knew that the part that had failed on my hot water heater was covered by a five year warranty. He contacted the manufacturer representative directly and saved me a lot of money. His work was excellent."
