I've been using Amerigas for 11 years now. Last year I could smell gas around my house. I called and they sent someone out that same day to fix the issue. I don't have to worry about my tank ever running out, they send someone out to check it and then fill it.
They are very friendly and responsive. We have auto delivery set up and it is very reliable. We recently had to call to check on our delivery b/c our percentage was 10% and it was several days until our scheduled delivery. They were very prompt in getting a delivery to us.
