When you call us we will ask you a few question to determine what size tank(s) you will need and what you use the propane for. We will then set up  an installation date. Once we have connected our tanks and tested your lines and system, you can notify your previous supplier that you no longer require their service. There is a small "setup" fee at the time of installation. This fee pays for us to set  the tank(s) and perform a leak test on your system, and to re-light your appliances.
