I run with the local yocal gas company, service is outstanding, as well as the prices. The tanks are " free " of rent as long as I keep putting gas in them. If I call them, the girl that answers the phone knows me when she answers ( guessing caller ID/interface with customer list ? ) Its also always the same girl.
OP, Id start shopping,, Ive been on propane most of my life, and had several providers, the smaller the better. I know Ive had Amerigas, as well, but its been too many years, but I dont remember problems. Ive had Farrellgas as well. Neither names bring me warm fuzzy feelings, seem to remember they had crazy prices.
Ive got a 1000 gal for the shop and 500 for the house, they have some kind of GSM device on them that tells them what the levels are, or if they get low they get some kind of " alarm ". As long as I pay the bill, its a pretty zero participation, on my behalf utility.
Not sure what your doing with a 100gal tank as far north as NJ, I think your about the same latitude as me. I cant make through the winter without both being refilled at least once.,.. or is 100 a typo, you meant 1000 ?
Im on a contract right now, without going and looking I think Im paying $1.25..
