Every CO2 supplier we could find in the Miami area (Florida) was checked one by one, and 19 of them made the list. 5 will refill the cylinder you walk in with. 11 only swap it for a different tank, which matters if yours is new or an odd size. 3 would not confirm either way, so those are marked call to confirm rather than guessed at. 5 confirm food grade CO2 for anything you actually drink; the common sizes here are 60L, 20lb, 5lb; most cover soda, welding, homebrew.

Official site explicitly confirms walk-in while-you-wait CO2 refills, beverage-grade CO2, service throughout Miami-Dade, and cylinder options of 5, 10, 20 and 50 lb. Included as a practical South Florida metro option for Miami residents. Email source: https://browardnelson.com/contact-us/.
Official site confirms Miami-area CO2 supply, certified food and beverage grade gases, and tank refilling. A February 2024 Miami customer report specifically documents same-cylinder 5 lb and 20 lb refills and says VS Carbonics does not exchange those tanks. Additional official tank-size page lists 5, 10, 20 and 50 lb CO2 cylinders but only 5 lb and 20 lb are retained here because those refill sizes were specifically documented.

Confirmed by Roberts Oxygen in October 2026: the CO2 is food grade and every branch does cylinder exchange rather than refilling the cylinder you bring in. Branch address, phone and hours from the company's own locations list. Stated company policy rather than a branch-level check, so confirm anything unusual when you call.
