Helium Cylinder Rentals and Refills
Short-Term Rentals
Great for: weekend events, private parties, corporate functions, etc.
We offer four helium cylinder sizes: large, medium, small, and extra small. Please see the chart below to help determine which size you'll need based on your desired output.

*All numbers are approximate and based on the amount of helium required to fill each balloon to optimum size
Reservations
To reserve a cylinder, we need a name, contact number, and pick-up date. Because we are closed on weekends, plan to pick up the cylinder on a Friday and return it the following Monday for weekend events. Should you require different pick-up and return days, let us know.
If you would like the cylinder delivered, we can hold a cylinder for you with the same information listed above. However, we will not deliver unless payment has been previously arranged or collected.
Helium
We do not issue credit for unused helium, so please select the cylinder size most appropriate for your party. If you run into a problem, please contact us as soon as possible so we can assist you.
Balloon Inflators
The inflator rental fee is $20. Let us know if you own one already, and we'll remove it from your order. Balloon inflators are verified to be in working condition before they leave our premises. If you are unfamiliar with how to use them, let us know. We'll be glad to show you.
Delivery and Pick-up Options
Delivery is available, and the price is subject to the delivery location. The round-trip fee, which includes taking the cylinder to you and picking it up, starts at $36. Please arrange for someone to be present at the time of delivery, as we will require a signature from a legal adult. If you are not signing for the delivery yourself, provide us with the name of the person who will be. A hard copy of your receipt will be delivered with the merchandise.
You may also transport the cylinder yourself. However, you will be required to sign a liability release form if you choose to transport it yourself. We recommend using a pickup truck, if possible, as it is safer to transport the cylinder in an open truck bed than in an enclosed vehicle. A valid TX Driver's License is also required to rent a cylinder. WE DO NOT ACCEPT ANY OTHER FORM OF ID.
Please ensure you're able to load and unload the cylinder(s) unassisted. If assistance is requested, the liability release form will also be required.
Security Deposits
A security deposit is required on all short-term rentals. The deposit amount is dependent on the cylinder size rented. All security deposits must be paid with a credit card or cash. The deposit is refunded when the cylinder and inflator are returned to our store. NOTE: All deposits will be returned in the same format it was initially paid with.
Long-Term Rentals
Great for: businesses/balloon decorators, commercial use and marketing
Long-term rentals are available for commercial locations, and only large cylinders are eligible for long-term rentals. For pricing and terms on long-term rentals, call us at 210-524-2345 or send an email to customerservice@heliumxpress.com. We're happy to answer any questions.

Safety is Our Priority
Helium Xpress Balloon Wholesale has many policies in place to keep our employees and customers safe. In upholding our commitment to customer service and safety, we've included the following information. We strongly encourage all of our current and prospective helium customers to review the following cylinder safety protocol.
DO:
- Do read and follow all safety notices on the cylinder.
- Do store, use, and transport gas cylinders in a well-ventilated area and/or vehicle.
- Do use a regulator specifically designed for balloon filling at all times.
- Do check cylinder connections for leaks once the regulator has been connected. This can be performed with soap and water.
- Do make sure to turn off the balloon filler valve between uses, as well as when the cylinder is empty.
- Do turn off the cylinder valve, remove the regulator, and replace it with the cap on the cylinder before transporting.
- Do use the cylinder for the intended purpose of balloon filling ONLY.
DO NOT:
- Do not attempt to transfer helium contents from cylinder to any other container.
- Do not store or use balloon gas in a poorly-ventilated, confined area. While helium is odorless and nontoxic, it may induce suffocation by diluting the concentration of oxygen in the air to a hazardously low level.
- Do not breathe any helium and NEVER put your face or mouth near the cylinder or filling equipment.
- Do not allow others to inhale helium from filled balloons.
- Do not store or use cylinders near extreme heat or electrical devices. The cylinder should not be exposed to temperatures above 130F (54C).
- Do not remove the cylinder cap until the cylinder has been secured in its place of use.
- Do not attempt to remove caps if they appear to be stuck. Instead, alert your supplier of the problem.
- Do not allow children to operate any balloon filling equipment. The cylinder MUST also be tightly secured to ensure it won't be knocked over, especially when children are around.
