March 11, 2024

DANVILLE, Ill., March 1, 2024 – Rentalized® HVAC and pump systems manufacturer American Event Services announced today it has closed on the acquisition of Canariis Corporation, a privately owned manufacturer of custom UL-listed packaged HVAC, plumbing and fire-protection systems. Under terms of the agreement, Riverview, Fla.-based Canariis will operate as a wholly owned subsidiary of AES under the leadership of Steven St. John, President of Canariis. St. John retains a significant ownership position in the combined companies. Tony Tauer, previously President of AES, has been named CEO of AES.

“Our years of working respectfully as peers and the common culture between the companies paved the way for this partnership,” Tauer said. “With the companies joining forces, our customers will benefit from the combined expertise and economies of scale of a more efficient operation.”

AES manufactures chillers, HVAC, pumps and power distributions systems exclusively for the specialized rental equipment industry. Canariis has a nationwide distribution network that markets its packaged systems for domestic water, HVAC, chiller plants, boiler plants and fire pump applications. Combined, AES and Canariis have four manufacturing locations totaling more than 150,000 square feet and 165 employees.

“I’m excited for the future of Canariis,” St. John said. “As part of AES, we immediately expand our manufacturing capacity to capitalize on significant growth opportunities in our industry. Employees of both companies will share their unique skill sets to efficiently create best-in-class customer solutions.”

Canariis manufactures packaged systems for domestic water, HVAC, chiller plants, boiler plants and fire pump applications from its facility in Riverview, Fla. All Canariis systems are fully tested at job conditions and include separate UL labels that cover the controls as well as the entire system. This helps to ensure simplified start-up procedures and years of trouble-free service. For more information, visit
