For will-call customers, we recommend placing your order when your tank reaches between one-quarter and one-third capacity. Please allow one to seven days for delivery scheduling.

Locate the transparent glass or plastic indicator tube positioned on the top of your tank. The gauge displays measurement marks similar to an automotive fuel gauge, showing F for full, three-quarters, one-half, one-quarter, and E for empty.

The average lifespan of an AC system ranges from 10 to 12 years. Regular annual maintenance helps extend the operational life of your equipment.
