"We were very pleased with the work that the Genove technicians did. They removed our 40-year-old gas boiler and associated water heater and replaced it with a new system. They tested the new system carefully, put explanatory tags on all of the relevant pipes and faucets, and cleaned up well. The team members were polite and worked hard. We had similarly good experiences when Genove technicians came to repair our central AC system. They were knowledgeable and efficient, got the system going again, and the price was fair. We continue to use this company for heating and AC repairs."

"Joe, the AirCo sales representative, was very professional. He actually asked for my feedback on priorities for a new boiler. This was important to me because the boiler sits below our family room, and the noise level of the boiler was as issue. His proposals listed several boiler options, based on heating efficiency, which were competitively priced. The installation was run by Steve, who was able to fit in the installation the next week. Steve, and his crews, were punctual and courteous, and the installation went smoothly. It's only been a week, but I am very pleased with my Bosch boiler, the quality of the work, the price paid, and the timeliness of the installation."

"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 couldn't recommend these guys more. We had a 21-year old boiler replaced and upgraded, and a new hot water tank installed. I can't think of a single way they could have improved the whole process. From start to finish, they were knowledgeable, on time, clean, considerate, extremely professional and they did exactly what they said they would. The also installed a temporary hot water tank and left electric space heaters on the one night the burner was out of service. Everything is now working as they said it would, and a big bonus is their workmanship actually LOOKS great too! A+++"

"Required $80 to come out and price out some very basic work. $80 to provide a quote??? Makes it impossible to shop the best price. I was able to find at least 2 other plumbers who provided quotes over the phone."
