Where to Refill CO2 Tanks: 10+ Places (Ranked & Vetted)
Running out of CO2 for your kegerator, SodaStream, or paintball gear doesn’t have to ruin your day. This guide cuts through the confusion to show you exactly where to get a fast, affordable refill or exchange across the United States. We cover everything from national chains to local hidden gems, updated with most updated pricing.
Before You Go: 3 Essential Checks
Avoid a wasted trip by verifying these three things about your tank before you head out the door.
1. Verify It’s Food-Grade CO2
Not all CO2 is created equal. Using the wrong type can be unsafe.
Food-Grade CO2: Required for any consumption, like carbonating beverages in a kegerator or SodaStream. It is highly purified.
Industrial-Grade CO2: Designed for applications like paintball or welding. It is not safe for consumption.
Critical Rule: Never use CO2 from a paintball shop for your drinks.
2. Locate Your Tank’s Hydro-Test Date
CO2 tanks require recertification every five years for safety. Look for a date stamp (e.g., 05 • 23 for May 2023) on the tank’s shoulder. An expired tank will be rejected for a refill, and you’ll likely need to exchange it instead.
3. Understand Refill vs. Exchange
Know which service you’re getting, as they are fundamentally different.
Service | How It Works | Pros & Cons |
|---|---|---|
Refill | The store fills your specific tank with gas. | Pro: Cheaper; you keep your tank. |
Exchange | You swap your empty for a pre-filled tank. | Pro: Extremely fast and convenient. |

Airgas: The Best for Homebrewers

ACE Hardware: Call Ahead First
Because each ACE Hardware is independently owned, CO2 services vary greatly by location. Some offer paintball refills or SodaStream exchanges, while others do not. A quick phone call will confirm your local store’s capabilities.
Finding Local & Budget-Friendly Options
For the best prices, especially on larger tanks, exploring local businesses is your best strategy.
Welding Supply Stores
Local welding shops are gas experts and typically offer the lowest refill prices. This is your pro-tip for saving money. Remember to explicitly request beverage-grade or food-grade CO2 for drink applications.
Homebrew Supply Shops
These specialty stores are tailored for brewers. They excel at CO2 exchanges for kegerators and are a fantastic resource for advice. Use the American Homebrewers Association directory to find one near you.
Fire Safety Companies
An often-overlooked option, many companies that service fire extinguishers have the equipment to fill CO2 tanks. Prices can be very competitive. The National Association of Fire Equipment Distributors can help you find a local provider.
