Horrible!! Not trustworthy at all! They are always right even when they are obviously wrong. We had new piping and tank put in when we built the house 6 years ago. Every 6 weeks they would come out and fill the tank 80% and charge me over $275 every 6 weeks I was only using it for a stove top. After we would complain they would send someone out to check for leaks and non was found. We finally we told them we would call when we needed more. We were at 40% when we told them to only come when we called, 40% lasted us over four years. We called them they other day and their prices are about $1 more a gal. than other companies, but because they own the tank no one else will fill it. They came out and filled it 40 % and checked for leaks and found none. Less than a week later, its at 0%. We noticed they put a new valve and we smell gas outside. They created the leak. I will be calling them tomorrow. I'll write about what happens after talking with them. They have us by the throat!
