Outstanding place to buy propane. The service was good. I'm old and have trouble with heavy things. The guy who filled my tanks took them out of my car, filled them, and then put them back in my car for me. The price was also very good. This is my go to propane place for sure. read more

Great LOW price! Friendly services and fast too! Be sure to read all of the signage as you enter(LOL) and when you think you are done reading the "rules", there will be more. Hahaha Tip: pay cash, it's cheaper. 1/24/2025 $3.09/gallon (cash) read more

I went in for a propane inspection and these guys helped me out immensely. Gave me great feedback and advice to be safe, while also being extremely helpful and friendly! Best inspection experience I've been apart of as I do a ton with my food cart. Great service and people here! read more

Very accommodating! Gave good instructions and made great recommendations. I would use them for all my propane service needs read more

I brought a couple of cylinders from my work. They repaired both of them and filled them. Very quick service! I would recommend them. And these are cylinders for our forklift. read more

I found Diamondback Propane on Yelp while searching for an alternative to a local grocery store or gas station to swap out my gas grill propane tank. Diamondback actually refills your tank and charges you only for the amount you receive. Our tank was empty and the cost was $15 to fill! You can't beat that! Also, it's quick and easy, just pull up to either side of the propane pump, they fill you up, give you a ticket and you go inside to pay. And if you're lucky you get to meet Sherie and she'll make you feel welcome and leave there with a new friend! If you need propane, do yourself a favor and check this place out, you won't regret it! read more

Competitive prices and knowledgeable friendly staff. What more can you say. I highly recommend them.

First time customer. Very efficient tank fill up and parking. I was able to drop the tank off and then park. They placed the tank back in my car and handed me the written amount of propane. Went inside and paid. Very easy. read more

Refilled 30 lbs tank on RV. Price was 3.09 gallon cash, 3.14 non cash Fast service friendly staff. More words needed . read more

Used this company for years before Diamondback bought them. Since then the service has become rude. The women in the office are great, but the men filling tanks are ignorant and act like propane nazis. Embarrassing actually. Taking my three thousand dollars a year and moving to Amerigas where hopefully professionalism means something. read more

This place is great very easy, you just pull up next to their gated propane refill and they will fill you up and give you a sticky not with the gallon amount on it then you bring it in side and they ring you up. Cash price is 5 cents cheaper but they are by far the cheapest price per gallon for propane anywhere I've seen. Propane is $2.39 with cash or $2.44 with debit/credit as of 11/9/21 read more

Just when you thought personable service was like dinosaurs, rolodex and fax machines, up drives the cheerful dude from Diamondback Propane. A career man so comfortable and assured brought the propane refill to my RV for a reasonable price, wait for it! On the same day I called Sherri in their office and she redirected the driver to bring what I badly needed. And for only a small additional fee. No issues, no problems, the way this kind of service maintenance should be, easy. Thanks to Diamondback Propane - friendly service, fair price... so simple - like the good 'ol days!w read more

Great service!!! Was able to get BBQ propane tank with built-in gauge when no one else had one!!'For great price as well. And they can refill it while I wait. Amazing operation! read more

Easy process to refill heater tanks. Pulled up, gave tank to the attendant and within a couple minutes had my 3 tanks filled and he put them back in my car for me. You then park your car and go inside and pay. Everyone was very helpful and nice. Great thing vs swapping out tanks at other places is you only pay for what you need. read more

Great people. In and out quickly. Much cheaper than Tractor Supply!! Will definitely use them from now on.

We have had nothing but amazing customer service with this company. My baby was recently in the hospital so our tank got down quite low without us realizing. They are doing an expedited delivery without any attitude or lectures. I was very impressed with everything they did, and offered. They really have been 10 out of 10 (since the first time I called them years ago) with Customer Service, Integrity, punctuality and so much more. This company is not just about making a buck. They have showed me that! Brooke was kind, delightful to talk with, and very fast calling me back with a decision. She even said she hopes my baby gets better each time we spoke. I didn't even except her to remember that I said she was sick. I felt like I was talking with a friend and I felt very taken care of. Wow! Way to go Diamondback! Customer service has kinda gone downhill but not with this company. Thank you kindly for helping us read more

Best price in town. They are friendly and fast filling your tanks. Cash saves you 5 cents per gallon.

Just an FYI to anyone in Queen Valley needing a propane delivery service...Don't bother calling Diamondback if you are looking for anything resembling Customer Service... I'm 70 yrs old and had to unhook and move my 4 #100 pounders out to make it more convenient for the young 20something to fill the tanks...once filled he said that he could not help me get them back in place or help hook them up claiming a policy issue... Diamondback Propane will not get another dime of my money...they are not there for your convenience, just your money. read more

They made a brass fitting for my propane tank many months ago. An undetectable (smell) very small amount of gas built up and permeated throughout my RV for four months. I was very sick for a long time and went to the doctor. To no avail. Subsequently, I stumbled upon this problem with a gas leak detector - over my bed. We went back and forth. Me saying there was a leak right there and them saying there was not and that smell didn't mean anything. They charged me a lot of money for their faulty part and installation. It cost me $228.49 to fix what was killing me by a reputable company. I went to talk to the owner to get re-imbursed for what they cost me. HA! Guess what he said. This company has ZERO integrity. read more

Cheapest price in town and best customer service! Just take your tank to the fill station and have the person fill it, load it in your vehicle and go inside and pay. Thank you Diamondback. read more

Great staff and easy access for motor homes! At 35 feet, we just about maxed out the turning radius, but it's tough to find propane for big rigs. read more

This company is terrible. I had my propane tank filled at a steep price tag of $180.00. I didn't use the tank for nearly 2 years, however when I tried to use it the propane was gone. They came out and inspected the propane tank and advised there was not a leak. They proceeded to fill both tanks without my approval and to top it off left my gate open so my dog escaped. The guy that makes the decisions - Bill, had nothing to offer except to pick up the tanks. I gladly accepted. What terrible customer service. Without saying it, they basically said I'm a liar and I must have used the propane because the tanks are fine. I'm happy to pay for the things I use. I'm now out $180.00 for propane I did not use. Pick someone else who stands behind their customers. read more

Awesome service and prices. Super nice and helpful Staff. Buying local matters and when it is also the best experience. That's a Win-Win for me. read more

Horrible parking and rude employees. We came today for the first time and safe today it was not worth the hassle.
