Every CO2 supplier we could find in the Jacksonville area (Florida) was checked one by one, and 15 of them made the list. 4 will refill the cylinder you walk in with. 5 only swap it for a different tank, which matters if yours is new or an odd size. 6 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 5lb, 60L, 10lb; most cover homebrew, soda, welding.

Current official site confirms CO2 and branch details. Customer feedback summarized on the current business listing specifically describes CO2 refills for aquariums, kegerators, and soda machines; at least one customer reports food-grade CO2 for a soda machine. Same-cylinder refill behavior is supported by refill-oriented customer reports.
Current business listing confirms active fire-safety shop. Recent Jacksonville evidence from Jan 17, 2025 says a former kegerator owner had a tank filled here and describes it as cheap and quick; current review summaries also mention CO2 refills for aquarium and beverage setups and odd-size tanks. Evidence: https://www.reddit.com/r/jacksonville/comments/1i3n6zo/co2_refills/ Email source: https://www.firstcoastfire.net/blank-6
Edge-of-metro branch included because Jacksonville gas suppliers explicitly serve St. Augustine and residents may reasonably use it. Current business reviews specifically describe quick CO2 tank fills, while other branch reviews describe CO2 cylinder swaps. Both behaviors are therefore supported at this branch. Call ahead if keeping the same cylinder matters. Email source: https://www.maineoxy.com/locations/staugustine-florida/
Current SoTec site identifies a Jacksonville operation and explicitly states its technical field services include recharging and hydrostatic testing of CO2 cylinders. Current location evidence places the Jacksonville branch at 1541 Main St Ste 3, Atlantic Beach. This is fire/industrial CO2 cylinder recharge rather than beverage-focused service. Email is corporate/general contact. Email source: https://www.sotecfire.com/contact
Official branch page explicitly lists carbon dioxide. Current business review evidence reports a consumer purchasing a 5 lb food-grade CO2 tank and planning to return for exchanges. Treat as exchange, not same-cylinder refill; call ahead for stock.
Official branch page lists beverage gases among possible branch products. Jacksonville community evidence: 2023 user reports routine 5 lb CO2 tank exchanges; Jan 19, 2025 user reports getting a 10 lb tank filled here every few months. Evidence: https://www.reddit.com/r/jacksonville/comments/123ndjq/co2_tank_refills/ and https://www.reddit.com/r/jacksonville/comments/1i3n6zo/co2_refills/ Same-cylinder refill is not confirmed. Community wording about getting a tank filled often describes an exchange, and the other Jacksonville Airgas branch is listed as exchange. Ask before you go if keeping your own tank matters.
Current Roberts location page confirms branch. Northeast Florida homebrew club lists this branch as a CO2 source. Current business review evidence specifically warns that this location does not fill CO2 tanks and only exchanges them. Homebrew source: https://www.thecask.org/knowledge/co2-sources/ Email is corporate/general contact. Email source: https://www.robertsoxygen.com/contact 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. The company stated this applies across all of its locations, so it is a company policy rather than a branch-level check.
Current official Target page confirms branch. Jacksonville community evidence from Jan 17, 2025 specifically says the Roosevelt Target accepts old SodaStream canisters at customer service and provides an exchange discount. This is SodaStream exchange, not standard 5 lb/10 lb CO2 service. Evidence: https://www.reddit.com/r/jacksonville/comments/1i3n6zo/co2_refills/
Current official Target page confirms branch. Jacksonville community evidence from Jan 2025 specifically says several Target stores in Jacksonville, including Southside, perform SodaStream exchanges at guest services. This is SodaStream exchange only. Evidence: https://www.reddit.com/r/jacksonville/comments/1i3n6zo/co2_refills/
Official Helget location page confirms Jacksonville depot. Official beverage-gas page explicitly says Helget supplies beverage-grade CO2 and blended beer gas. Service is delivery-oriented; cylinder refill-versus-exchange behavior at this depot is not established.
Current Jacksonville business listing confirms local depot. NuCO2 officially states it provides certified beverage-grade CO2 and supports restaurants, hospitality venues, breweries, high-pressure cylinders, and scheduled CO2 delivery. Local cylinder refill-versus-exchange mode is not established.
Current official Maine Oxy page confirms this location, formerly Strate Welding Supply. Northeast Florida homebrew club lists the same branch as a CO2 source. Current refill-versus-exchange policy was not established for this branch, so mode remains unknown. Evidence: https://www.thecask.org/knowledge/co2-sources/
Current official page identifies this as a production facility serving the Jacksonville metro and says production facilities are not open to the public. Current business data indicates CO2 production/distribution capability. Included as a business/industrial supply location; call before arranging service.
Current official nexAir page confirms Jacksonville retail branch and explicitly lists CO2 among gases carried. 2025 JEA bid documents confirm the 2312 W Beaver St address; Northeast Florida homebrew club lists the branch as a CO2 source. Recent reviews mention bottle exchange generally, but not specifically enough to classify CO2 mode. Evidence: https://www.thecask.org/knowledge/co2-sources/

Current chamber and 2026 business listings confirm the homebrew shop is active. Northeast Florida homebrew club lists The Brew Shed as a CO2 source. Current evidence does not establish whether CO2 service is refill or exchange, so mode remains unknown. Evidence: https://www.thecask.org/knowledge/co2-sources/
