The fastest way to fill a grill propane tank is at a local propane company, since technicians inspect the cylinder and fill it to the exact amount you pay for. Tractor Supply, Ace Hardware, and U-Haul also offer refills at select locations. Still, hours and availability vary by store, so calling ahead is always a good idea before you drive over with an empty tank.
The Empty-Tank Moment Nobody Plans For
You already know the feeling. The coals of the conversation are just getting good, someone’s flipping burgers, and then silence. The flame drops, sputters, and dies. Your tank is empty, and your guests are hungry. Refilling is quicker and usually more reliable than most people expect, once you know where to look and what to check for.
Refill vs. Exchange: Why Refilling Usually Wins
Exchange cabinets outside grocery and hardware stores are convenient, but you’re trading your tank for one you’ve never seen before, no idea how it was stored, how old it is, or how full it really is. Exchange tanks are also often swapped at a fixed percentage fill, which can leave you short on grilling time compared to a full refill.
Refilling keeps you with the cylinder you already know. A technician checks it for dents, rust, or valve issues, confirms it’s within its certification date, and then fills it based on weight, not a flat estimate. That means you get what you pay for, and your tank gets a quick safety check every single time. If you want the full breakdown of costs and trade-offs between the two, our earlier comparison on propane exchange vs. refill walks through it in more detail.
Popular Places to Fill a Grill Propane Tank Near You
Local propane companies. This is usually your best bet for both speed and safety. Technicians who handle propane every day are quick to spot a warped valve or a tank nearing the end of its certified life. Union Propane fills portable grill cylinders at our Central Ohio locations, so it’s an easy stop before a weekend cookout, a tailgate, or a camping trip.
Tractor Supply. Many locations refill standard 20-lb grill cylinders, but not every store offers this service, and hours can shift seasonally. A quick call before you load up the tank saves you a wasted trip.
U-Haul Centers. Some locations refill portable tanks as a side service, though this depends heavily on the specific center; it’s worth checking online or calling first.
Ace Hardware. Select stores refill cylinders, while others only run an exchange program. Again, this varies from store to store.
Independent local propane dealers. Smaller, local operators often move faster than big-box stores, with shorter waits and staff who can actually answer questions about your tank’s condition, not just ring up a transaction.
A few habits make any of these stops smoother: keep the cylinder upright during transport, secure it so it can’t tip or roll, and never leave a freshly filled tank sitting in a hot car longer than necessary. Heat builds pressure, and propane tanks are built with that safety margin in mind no reason to test it.
How Long Does a 20-Pound Propane Tank Actually Last?
Most 20-lb tanks run for roughly 10 to 20 hours of grilling time, though the real number depends on a handful of things:
- Your grill’s BTU rating
- How hot do you typically cook
- Wind conditions (windy days burn through gas faster)
- How often do you fire up the grill
- How many burners do you run at once
Someone grilling burgers twice a week will stretch a tank much further than someone hosting a full backyard cookout every weekend. If your tank seems to run dry way faster than it used to, it’s worth ruling out a leak or a worn hose rather than just assuming you’re cooking more. Our guide on why a propane tank drains fast covers the usual culprits.
What Actually Happens When a Tank Gets Refilled
A proper refill isn’t just “hook it up and go.” A trained technician checks the tank’s exterior for dents or corrosion, confirms the valve and certification date are current, and fills it using the 80% rule: propane expands with heat, so tanks are never filled full, which is a safety standard, not a shortcut. Once filled, the tank gets weighed to confirm an accurate fill before it’s handed back to you.
That small amount of oversight is the real difference between a refill station staffed by people who work with propane daily and a self-serve exchange cage.
Can You Refill Propane at Home Depot?
Home Depot doesn’t typically refill tanks in-store; most locations only offer an exchange program through a partner service. If a full refill (versus a swap) matters to you, a dedicated propane provider or a store with an on-site refill station is the better stop.
When It’s Time to Move Beyond a Portable Tank
If you’re filling your grill tank every week or two through the whole summer, or you’re running other appliances like a patio heater or fire pit off propane, it might be time to think bigger. Many Central Ohio homeowners eventually switch to a residential tank with scheduled delivery instead of repeat trips for a portable cylinder. Our propane tank installer services cover everything from above-ground tanks to full residential systems, and pairing that with a seasonal pre-buy program is a smart way to lock in supply before peak grilling and heating seasons hit.

Many locations do refill standard 20-lb cylinders, but not all stores offer the service, so it’s best to call ahead.

Typically, 10 to 20 hours, depending on your grill’s BTU output, cooking temperature, and how often you use it.
Q.3 Can I refill propane at Home Depot?
Most Home Depot locations run an exchange program rather than an in-store refill, so a dedicated propane provider is usually the better option for a full refill.
