Called a couple of times, left messages with no response. Then made a request via their website. They responded via email saying they can’t help while not really explaining why . I can’t believe they are a preferred Rinnai service provider!

Ray is very responsive to phone calls and emails, and I knew on the day that he came by to give us an estimate on installing new gas piping and a gas range that it would be a pleasure doing business with him. Ray and his son are fast, efficient, and their quality is second to none. When they checked out our basement to plan the work for gas piping, they were quick to spot our leaking electric water tank, which I had planned on replacing with a tankless gas-powered water heater sometime in the future. In a down-to-earth, non-salesy way, Ray helped me understand the life expectancy of an already leaking tank which put into perspective the sense of urgency I was lacking on replacing the tank. Then, Ray broke down for me the estimated cost the inefficient, leaking electric water heater was costing me per month versus what the tankless gas-powered water heater would cost, not to mention the energy star rebate I hadn't even considered. The savings on my electric bill will basically pay for the new water heater. Long story short, they were able to come back within a week and get all the work done on the same day, and I couldn't be happier. My next project is to replace my old oil furnace with a natural gas furnace, and the only call I plan to make is to DeFosses Plumbing & Heating. Thanks Ray!

Ray DeFosses installed the plumbing for our new home (over a year ago). We've contacted Ray several times with questions and minor issues. Ray has always been very responsive, professional, and very friendly. Recently, we had a frozen drainage line from our humidifier and weren't sure if it was a plumbing problem or an HVAC problem. We left a message with Ray and our HVAC contractor, and although Ray knew it was an HVAC issue from our description, he contacted us immediately. Ray provided a simple yet comprehensive solution for eliminating scale buildup within plumbing lines and fixtures. Ray rates at the top of all subcontractors we've dealt with. We've received nothing for this review, but took the time to write this as Ray deserves the recognition.
