Absolutely the best propane service around! Great pricing, excellent service and truly professional owner and service people. I wish I'd found Promise Propane many years ago and saved myself a lot of money and headaches.

I live in Waterbury and have been using Promise for years now. It has always been great service at a good price, and I have had zero complaints.

I really expected to find a 100 5-star reviews. Fast service, good price, professional. I'm not sure what else you could ask for. Would recommend.
