"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 have had several Sila visits in recent months - all exceptional. VISIT 1: We had old pipes and valves that limited our dishwasher, so we had that replaced. While there, the Sila agent suggested we replace some of the attached lines and managed to streamline our hookups by removing some of the unneeded valves and connections no longer needed. VISIT 2: We similarly had a great visit and instal from David, who did a very beautiful install on our new water heater. He removed the broken unit, improved the connection design, put in improved valves and labelled each with a tag, then tagged other connections through the basement."

"JT called and asked if he could come earlier than expected, which was perfect for me. He was extremely thorough reviewing our electrical system and the finished product of the work he did (installing a new 220v line for an outdoor hot tub) was clean and efficient. He was a joy to meet and speak to, incredibly nice guy. Price was reasonable for the work. I would 100% recommend JT and Cotti-Johnson again!"

"I canâ t say enough great things about Minuteman Water Heaters! I had extended family in town when my water heater blew on a Saturday. They responded quickly and professionally. For a weekend emergency they were also very reasonably priced. The entire process was so smooth. I would recommend them to anyone. Many thanks again!"

"I recently had a new heat pump system installed by Trust 1, and the entire experience was outstanding from start to finish. Their team was professional, knowledgeable, and respectful of my home. The installation was smooth, on time, and the system is running perfectly. It’s rare to find a company that truly lives up to its name, but Trust 1 absolutely earned my trust. I couldn’t be happier with the service and results — highly recommend them to anyone needing HVAC work!"
