I pay less than $20 after tax for refilling my 10# tank at the fire extinguisher place near my house. I just bring it in and they'll fill it up there while I wait. I've also noticed that the turn on the CO2 for about 30-60 seconds before filling the tank (I assume to flush the lines), is this a common practice? If so then it would explain why there's not much of a price difference between the 5# and 10# tanks.
 
Local welding supply shop, if you have an account with them and own your tank it's $15 for 5 lb. My tank is brand new and aluminum, I wouldn't want them to swap it.
 
My 5# tanks at the LHBS are 22$ for an exchange. Before I moved, I was really close to an Airgas, who just refilled my tank (with my account) for 12-15$.
 
Airgas swapped my 5# for right around $20. They swapped my 10# for only a few dollars more. I can't recall exactly what I paid, but I was unhappy with the 5# price, but thrilled with the 10#. I'll likely not look for another company, simply because they are conveniently located for me to stop in on my way home from work.
 
Whelp everyone is getting screwed. I went to get my 5# tank filled again at my local fire extinguisher place and when he was done I said how much? Again he said eh don't worry about it, it's only $1 a pound it's not worth the paperwork. Now I'm sure he's talking his price, but I've definitely hit the honey hole. Might have to take these guys some homebrew.
 
I recently found a local welding supply shop while looking for gas. When I called for prices, the guy asked if I was okay with food grade since that is what he keeps in 5# and 20# tanks for local bars and restaurants :D I guess I can live with that. $5 and $10 respectively is what he charges for an exchange. He takes my tanks without even looking at them and gives me brand new looking ones. I'm pretty happy about this place, and it is across the highway from where my wife works. I mentioned that, and he said that if she brought them, he would be happy to unload and load the tanks for her. I think I found my gas supply.
 
In the middle of nowhere Indiana where i live, a 5# tank swap costs $13 at the local welding supply place.

I'll second that, I'm in nowhere Michigan and a 5# tank swap costs me $13-15 at the local welding supply place.

No sure why the price varies, seems to change with his mood that day. :tank:
 
I've heard any place that has paintball equipment like sporting goods stores can fill or exchange tanks also. Haven't looked into it yet but am about to. Ready to fill my very first keg.

They generally only refill paintball tanks. If you find one that does happen to fill larger tanks, I doubt it would be cheap.
 
$15.22 for a 5# fill at a local welding shop that has a lot of gasses on hand. That is after tax and fees. I'll keep using them, since they are just down the road from work! I only bought a new tank with my keg set up because I knew they fill on site, and are very close to work...
 
I just paid 30 dollars plus tax at Airgas for a 20LB cylinder.

See, this is what grinds my gears. Mind me asking what state you're located in? Airgas charged me over $20 for a 5# cylinder a couple months back.

ETA: I know bigger cylinders are cheaper.

I had it filled in Gainesville, FL. I love having the bigger cylinders.
 
None of the welding places near me will do it. They all refer me to where they get theirs filled which is a 30 minute drive to Holston Gas. Not sure about the prices, they were closed when I called. I'll update when I find out.

Update: $16.39 total to fill my 5lbs cylinder at Holston Gas in Knoxville, TN.
 
just filled up two 5 lb tanks for the first time at the fire protection place near me. $10 total and that included tax. plus the guy threw in a couple fiber washers for the regulators.
 
A person would do well to get a 20lb bottle, it's easy to find a place to swap/fill them economically. Not to mention with the 5lbs your constantly having to get a fill or swap.

At my local Airgas they have always jerked me around on filling/swapping 5lbs, 14-21 bucks. But they'll fill a 20 lb for just a little over 20.
 
I can fill a 5# at a fire extinguisher place for about $10. Only did that once as their location and business hours kind of suck.

Then I discovered a paintball place just down the road from me that will fill 5# tanks for $20 cash (he charges slightly more if using debit/credit card). Best part is he's open all weekend long. Comes in handy many times when I had to get a tank filled on a Saturday.

i initially bought two #5 cylinders since i got them for a steal and the place by me charges by the pound regardless of vessel size. i figure i may need to stop in more often for refills but have started rethinking this, sounds like it will eventually be a hassle. i'm thinking of getting a #15 or #20 tank for my keezer and using one of the #5 tanks in my brew area for purging kegs and racking/transferring, also for transport if i want to take a keg somewhere. the second #5 tank would be my emergency spare if either of the other tanks goes empty.
 
Going to get a refill/exchange today, I'll be sure to report back. Going back to Praxair today to see how much difference the price is from the last time I was there.
 
My LHBS will refill 5# tanks for $15. If your hydro test is out of date they'll swap it out for a recently-tested cylinder for $10. Great deal and great service.
