JHL Supply has more than 40 years experience in meeting the needs of HVAC professionals. The company was founded by John H. Leavey, an inventor and entrepreneur who was commissioned to develop a pilot cleaning pressure pump for gas servicemen in the Syracuse, NY area.

Leavey developed the Leavey Pilot Cleaning Pump Kit (AK114) in 1956, a design so advanced that it is still sold today. The acceptance of this quality pump led to the establishment of this company, John H. Leavey Manufacturing, Inc., which grew steadily until his death in 1971. The company was acquired by his daughter and son-in-law, Pat and Tony Sciacca, who tended the business in Mr. Leavey’s memory.

In 1994, Pat and Tony Sciacca retired from the business, at which time John H. Leavey’s grandson, Thomas J. Sciacca, assumed control of the company. Honoring his grandfather’s name and commitment to providing high quality products for the HVAC, gas and electric service industries, Tom advanced the company in new directions.

In 1996, the company launched its premiere web site, which highlights JHL Supply’s products from manufacturers such as Leatherman. The site was revolutionary in the industry, making it easier for HVAC professionals to research and buy tools, whether its high-end refrigerant recovery machines or handy Leatherman Wave.

Three years later JHL purchased HVACtool.com and introduced their new e-commerce web site in their effort to meet the industry’s changing needs. The new sites are the result of customer requests for easier ways to find and buy service tools online.

In 2001, the company officially changed its name from John H. Leavey Manufacturing to JHL Supply to reflect its increasing emphasis on superior customer service and support. As the HVAC industry continues to evolve, JHL Supply will remain on the cutting edge. The company is committed to providing the best possible service and products at low, mail order prices.
