Awesome service. Clean facility. I've been refilling co2 for my Power Tank here. Make sure your tanks are emptied the night before. Currently my tank is there for re-certification which needs to be done every five years. It cost me $36 to refill my 10 pound tank. And $39 for re-certifications. Re-certs take about a week so be prepared to leave your tank. read more

Giant CO2 - Brewing Supplies Near Me - Santa Ana, California

My wife and I made the decision to purchase a bulk cyclinder of CO2 for our Soda Stream. I yelped sources for tank purchases, convenience of refills, reasonable prices, and awesome customer service. Giant CO2 checks off all four requirements! I stopped by their location on a recent Friday morning. The front door to the office, adjacent to the visitor's parking area was locked so I walked over to the first roll up door where there are several orange traffic cones. This, I later learned is where one is suppose to go for ant type of service need. After speaking with a very friendly and helpful staff member, I purchased a 5 lbs. cyclinder that was pre-filled with CO2. Pre-Tax was $109.00. After tax total due was $119.08. I really appreciated all the information and helpful tips explained to me in a very casual, friendly manner. Yes I could've ordered an empty cyclinder for less money, and fill/refill closer to my place of residence, but after the great customer service I experienced, I'm willing to stop by after work and wait until they open at 9 AM (Open M-F only). read more

See all

Quick and concise. Thank you for making are day greater. We will definitely be back. I recommend anyone for their CO2 needs.

Today was my first time here to fill a tank. David came out to meet me and had my 20lb tank filled in under 5 minutes. I'm extremely satisfied and will return here for my next refill. read more

I went here to fill up my CO2 canister and was in and out in 5 minutes practically. Super friendly staff and very professional. Highly recommend! read more

I brought a tank here for a refill. The price was very reasonable compared to other places I considered. The gentleman who helped me refilled my tank in under 3 minutes, and I was on my way. Like the other reviews say, he was very pleasant and professional. I will definitely return. read more

Got my CO2 tank refilled here for my planted aquarium. It's a good deal. Friendly staff.

Fast and easy refill for CO2 tanks. Very polite and efficient service. Only cons are that they close early by 2pm during weekdays and are not open on weekends for walk-in service. Also, they recently raised their prices by $6 to $34 for 20lb tank refill which is a 21.4% increase. Wish they offered cheaper price for 10lb or 15lb tanks, but nope - same $34 price (as of 7/21/23). Also, for safety and liability, they will not load or unload your tanks off your car/truck, so make sure you can lift yourself or bring extra help. Note: this biz refills gas for other businesses, so go directly to them. Don't go to those brewery places where they're too lazy to do a full refill for you. read more

I happened to find a place while looking for a tank because I needed to charge it. When I went there for the first time and was foolish, the employee came out and asked kindly and quickly charged it. Finish everything in 5 minutes and go home happily. read more

This is my first time getting CO2 for my new tank and the owner was super friendly and helpful. He wanted to make sure my tank is safe to use instead of trying to make a quick buck. Checked to make sure it has the proper DOT certification for safety check. Answered all of my questions and then some. Will definitely come back for future refills. read more

I only know of this company because they (Sandy?) returned my call on Monday when I left a message on a Sunday. Sandy did everything in his power to discuss my questions/CO2 needs as one person to another... not trying to sell me or steer me. Nice guy and I may just drive the extra 45 minutes to deal with this company rather than find a place closer to me (which was his suggestion!) read more

We purchased a used co2 tank off of marketplace for what we thought was a good deal for our home sparkling water maker. We called around the find the best pricing to refill it, which happened to be giant co2. When we showed up and were promptly notified that our tank had expired and needed to be inspected again. Bummer. More money. But seriously, these guys have been so nice and easy to work with. Their pricing for refill is the least expensive in the closest cities and they are the nicest. You can't go wrong with them. :) read more

Great personal service. I showed up after the 2:00 open to the public cut off time, I didnt check their hours before shoping up, but the owner opened up the gate for me and let me in. Turned out my tank had expired, but offered to hydro and fill it by the next day--saved my 4th of July party. I highly recommend read more

Always friendly and quick service. Would recommend them for all CO2 needs. In and out in about 5 minutes or less.

I only need to get my Co2 tanks refilled everything 1-1.5 years or so but I have been using Giant Co2 for over 5 years as residential client. I have had nothing but positive experiences from purchasing tanks, refilling, and getting them hydrostatic tested every 5 years. The staff is always friendly and personable. As a residential client, simply show up during their residential hours and they are there to help. They also respond to emails within 1 business day in my experience. read more

Incredibly professional, friendly, and knowledgeable team and owner! I went in for the first time after calling them for co2 for my aquarium setup and they treated me like a long time customer. I would recommend them to anyone needing co2 for business or personal use. read more

Quick and easy place to refill CO2 and/or Nitrogen - been doing both for my homebrew and cold brew. Wish they were open past 2pm though or for a small part of the day on a weekend just in case read more

Most companies nowadays just employ robots that pick up the phone and give you scripted responses. What a pleasant surprise it was to call this company and have the owner answer the call! No menus, no long hold times, no confused agents... Sandy was extremely nice and informative, gave me all the information I needed and was just very pleasant to speak with. He patiently answered all my questions and never gave me the feeling that he was in a hurry or needed to hang up. This company represents the exact type of people I like to do business with. read more

Rich !!! It's the men !!!! This place it's awesome!! Went to get some refill on a co2 and the team it's amazing 100% I recommend this place !! Thank you guys and they give me a little knowledge about tanks !! read more

First experience with this business and it was a good one. Little knowledge and history lesson was involved and it was all appreciated. I will definitely be back. read more

Clearly, they are more than equipped to handle commercial orders; but what I appreciate as well is their ability, friendliness and willingness to serve the needs of small orders as well. They are fast, reliable and informative, evaluating my tank and fittings and giving me excellent primer info about how CO2 works, how to store it and how to use it. FIVE BIG STARS!! read more

Been a customer for over a year the delivery guy is always pretty rude, but today he came to do the refill I wasn't at the shop to write a check and he said well we have to take the tanks which wasn't going to happen basically had to get a customer to throw him out acted like a little gangster! If your a business just get ur own tanks and get them refilled yourself these guys take 2 tanks everytime they say they have to which is not right just making money off nothing other places are cheaper!!! Definitely would not recommend these guys!!! read more

Our restaurants use this company and the customer service is the best!
