In addition to long term and short term helium tank cylinder rentals, Balloon Ideas also offers a line of refrigerants to customers in the San Antonio area. As R-22 Freon is slowly phased out of productions, new refrigerants are taking the place. The Balloon Ideas - allgas Division is currently stocking R-22 Freon, R407c Refrigerant and R410a Refrigerant. We offer free refrigerant delivery in San Antonio, or you can pick-up at our Balloon Ideas - allgas Division warehouse off of I-35 in northeast San Antonio. EPA Certification is required for refrigerant purchase.
