Refilling vs. Exchanging in Denver
Exchange — common at hardware stores, gas stations and home-improvement retailers — swaps your empty cylinder for a filled one on the spot, though exchange cylinders are typically filled to around 15 lb rather than a 20 lb tank's full capacity. Refilling at a dedicated propane dealer fills the same tank to its actual rated capacity and is usually cheaper per gallon, but takes a few minutes longer and isn't offered at every location below. Call ahead to check which service a listing offers — see our full refill vs. exchange breakdown for the cost comparison.
