Don’t Just Take Our Word For It! 

“Excellent folks to deal with. They walked me through setting up my propane account with them and I felt like they really valued my business!”- Jimmy R.

“Home propane tank hit empty with freezing temps outside. Discovered around 6am, they had my tank refilled and appliances reignited before 10am!” – Joe R.

“I have been a customer for the last 12yrs. At first I was just a call in to have my tank filled as needed, one time when I called the office staff mentioned a program they have in which you contract a certain amount of gallons and then you get it locked in at a better rate. I was so happy they mentioned this to me and now we have done that the past few years. The staff is always friendly. Definitely happy with my service.” – Konnie S.
