In this episode of Building HVAC Science, hosts Bill Spohn and Eric Kaiser sit down with Jeff Cherif and David Madden from JB Industries, a long-standing, U.S.-based HVAC tool manufacturer with deep roots in Aurora, Illinois. Jeff shares his fascinating journey from Motorola executive in Dubai to co-owner of JB Industries, sparked by a chance rooftop encounter with one of JB's own vacuum pumps in the Middle East. David brings a multi-generational connection to the business and reflects on the evolution of JB's manufacturing ethos and engineering depth.

The conversation dives into what sets JB apart: a true commitment to American manufacturing, ultra-durable tool designs, and a strong feedback loop with HVAC contractors. The team shares stories behind new product development, including their latest line of wireless probes and a replaceable-sensor micron gauge. They emphasize quality, repairability, and a willingness to collaborate directly with field pros who have fresh ideas. It's a heartfelt and detailed look at a company staying grounded in principles while pushing innovation forward.
