"I purchased a heat pump electric water heater to take advantage of a generous rebate from Efficiency Maine. When looking for someone to install it I was referred to Jophil by a real estate company that I know. I called and was given a time that Kyle would arrive to give an estimate and perform the installation (if the estimate was accepted). I did accept the estimate and Kyle got right to work. He did a nice job and made sure that everything was in good working order before he left. I was very pleased with my first experience with this company and would not hesitate to call on them again in the future."

"Excellent communication from Keith; outstanding service from Roger. Professional, timely, and reasonably priced. They came in under estimate on my boiler repair and advised that a second bit of work that had previously been discussed was not going to be necessary. I will definitely use them again and highly recommend them!"

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"Great! The owner, DF Richard, came out personally before our first filling to introduce himself and explain everything. Shortly afterwards, we had a wicked bad storm and lost power for 2 days, so we really needed the propane. They even topped off my tanks during the power outage, not because I called, but because the driver was in our area and wanted to be sure that we had enough fuel to keep our generator running until power was restored. Awesome customer service!!"

"Scheduling was challenging. On the first attempt, the service guy never arrived. When I called, the scheduler said there was some computer error, apologized, and rescheduled. On the second attempt, the guy came and did the service, then recommended having the expansion tank replaced. I was supposed to get a call to schedule the follow-up service, but never did. I called a few times and left a message, eventually getting a callback from someone who was able to schedule the service. Once again, the first attempt was a flop. They sent out a heating technician, not a plumber, to replace the expansion tank, which he was not certified to do...and he arrived late. On the second attempt, the plumber arrived on-time. He was very professional, efficient, and did great quality work. He made a recommendation for some other plumbing work after I asked him about an issue we had been having. He told me to call the company to schedule the work. Once again, I struggled to even get the service scheduled. This time, I gave up after 3 or 4 tries. I'll be contacting another plumber to get the work done at some point."
