When our old tankless water heater went down, we called LimRic. The bad news was that we needed a completely new unit; the good news was that LimRic and Caleb Rioux did the job. The experience from the time we first talked to a customer service rep through installation was absolutely fantastic. Our technician Caleb was amazing. He was knowledgeable, friendly, and professional, with the utmost attention to having the job done exactly right. We couldn't have asked for more.
