Residential propane
Keep Full Delivery
Keep Full is our automatic propane delivery program. We track how fast you use propane and schedule the fill before you run low.
What it is
Keep Full Delivery, explained
Keep Full means you are on our route and we are en route when your tank needs filling using your usage history and the weather.
You don't have to read the gauge and place an order. We take care of that for you. If something changes at the house, such as a new appliance, just call the office and we will adjust.

Common questions
Do I still need to check my tank?
Not necessarily, but keeping an eye on the gauge never hurts. If it looks low, feel free to call the office.
What if I add an appliance or my usage changes?
Call us and we will update the account so the forecast stays right.
How often will you deliver?
Our protocol for every Keep Full account with a monitor is that once the monitor reads 30%, we schedule the delivery on a route.
Is there a fee to be on Keep Full?
There is no charge to be on Keep Full. You also get a free tank monitor, and an additional 0.30 off the regular price of propane.
