Cylinder refill and exchange covers the small propane tanks that run grills, patio heaters, fish fryers, and camping stoves, usually the standard 20-lb size, though some spots handle 30-lb and 40-lb cylinders too. You either swap your empty tank for a filled one on the spot, or you bring your own tank and have it refilled by weight while you wait. There are 15 businesses in this category around Cape Coral offering some version of this, from dedicated propane dealers to hardware stores and gas stations with a fill station out back.
Refill by weight almost always gets you more propane for your money than a cabinet exchange, since exchange tanks are often not filled to full capacity and you're also paying for the swap convenience. If you go the refill route, the tank needs a current certification date stamped on the collar (cylinders are good for 12 years from manufacture, then need requalification), and the person filling it should check the valve and visually inspect the tank before hooking up. A reliable operator will weigh the tank before and after, so you can see exactly how many pounds you paid for.
Our rankings weigh things like posted pricing, hours that actually match what's listed, how consistently a location has cylinders in stock, and whether staff handle certification and safety checks properly.
