"Fantastic. Jeff is a pro. Installation went as described in both locations. He came back Immediately when I had a water gauge issue for my water meter ( installed 7 years ago) and replaced it on the spot. Jeff is professional, punctual, cleans up, old furnace removal and does great work. I’m very happy with my 2 new efficient heaters and hot water heaters! My heating costs are down substantially! I’m glad we chose Jeff."

"Brian and his crew were great. Brian came out and gave a great estimate for everything I needed. He was very responsive via email as we worked to schedule a time for his crew to come do the work, which was mainly water tank and heating system maintenance. Brian brought Jim promptly and explained the work. They then pointed out a couple of things that they recommended replacing, one they just included in the original cost estimate and another they added on due to additional parts being purchased. Jim was very thorough and professional and, by all accounts, did great work. I’ll be using Heavy Doody for all of my future plumbing and heating needs!"

"I've called Sila before to work on my HVAC unit and realized they offer plumbing services when my tank-less water heater stopped working. They were able to come by that day I called to see what was wrong. Once they were onsite they deterimed my hot water valve stopped working and were able to replace it and got my hot water working in no time."

"Replacement of 2 heating and a/c systems. Went very well. Professional, courteous, and thoughtful."

"I definitely will go to them again for any future plumbing needs. Not only did he make the requested repairs, he figured out why there was no hot water to the bathroom and corrected it.

"They installed a very complex Bosch Combi furnace and water heater. The precision of the work and the end result was excellent and frankly was very close to a major work of creative art! They did a great job."

"The repairs were professionally completed; however, I thought the cost was a bit excessive for the amount of time and materials required."

"These guys are great. Water heater broke and was leaking all over the cellar. They replaced my water heater and had everything done within a couple of hours. Highly recommend them and I will definitely use them again. "
