"Neo was excellent! My water heater went and a new one was installed by Neo and his team the next day. They were very professional, communicated instantly, and did a fantastic job. Will definitely use S.S Piping n Heat for all of my future plumbing and heating needs. Would recommend this company to anyone!"

"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."

"Responded immediately to the side effects of a water break in the house. Immediately restored electrical services to dry areas, came back a few days later to restore more services. Gave detailed proposal before work was initiated, had enough supplies on truck to immediately replace most of affected parts. and advised on purchase of replacement fixtures. The technician was cheerful and understood my goals in restoring service."

"I cannot recommend these guys enough! I am not a patient person, when it comes to work on my house. They EXCEEDED my expectations! Their install was professional, well communicated, clean and efficient. Work was done while my twin babies were home, and they were incredibly accommodating. Their service people have been quick to reply to every question I have had after install was completed. I, honestly, will never have to shop around again - Comfort Professor will be my first and only call."
