"Robert Johnson was so helpful in discussing the h/w heater installing and the venting requirements. His price was so much better than others companies in the area. His crew for the actual install was as also great! Kevin, the crew leader, explained how everything works and the cleanup was perfect!"

"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."

"Technician showed up ontime. There were no surprises. There were no "extra" charges or sale pitches to sell me things I didn't need. Technician offered suggestions and answered all my questions without hesitation. Thanks."

"Tyler & his team were very professional and thorough with repairing my tankless water heater. Tyler was quick to respond to my call for a repair service call and took the care to be as neat as possible during the repair and cleaned up nicely when the service was completed. TOP NOTCH !!!"

"They came out when they said they would, diagnosed the problem and gave me a quote for repair/replacement during the visit. Within a few days they scheduled the replacement work."

"Gil’s work was clean and very well done. He gave multiple updates of his work throughout the process. You can tell he really cares about the quality of work that he does."

"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!!"
