very professional and polite
We have been having a recurring problem and Will finally fixed it.
was on time and did great job
Always reliable and thorough
Very prompt
Jeff and his associate seemed quite competent and fixed the issue with our air conditioner quickly. I remain hopeful that it is a permanent fix and not something that repeatedly malfunctions. It was unfortunate that the company couldn't schedule this visit for two weeks after the initial issue was discovered, despite my annual service protection program with them, meaning we had to function without air conditioning during a number of very warm days.
Needed an adjustment to hot water. Dan arrived on schedule. He was able to quickly resolve the issue. Thank you Dan.
Austin Burns is an excellent technician. He is professional, knowledgeable and willing to take the time to answer all our questions. He is certainly an asset to Sippin!
Austin was knowledgeable and performed service in a very professional manner.
Thanks! AC broke on a hot day. Sippin dispatched Dan within a few hours and he fixed it quickly. Great service.

Came out in a snowstorm to deliver our oil. Very appreciative.
Dan promptly and professionally responded to an oil burner outage at my home. I figured out the problem was an empty fuel tank. Which was unusual I am on a scheduled oil delivery program. Dan assessed the quickly and was able to add fuel oil, and the burner was immediately back on line. Dan was most professional and courteous as I have come to consistently fine with the Sippin team.
As always your techs are fabulous. Always courteous, professional, prompt and extremely competent. We have always had a great experience with service. Thank you!!
This was an emergency call for oil burner noise. The technician showed up promptly and was extremely diligent to make sure the motor was replaced and everything was working fine before he left. We have used Sippin Energy since 2018 and their response and service performance is truly outstanding.
On time, polite, friendly, and thorough, replaced parts that needed to be replaced, even though I didn’t know it was necessary. This is why I’ve been with Sippin for 25 years.
