Commander Air + Plumbing + Electric’s fleet design blends memorability with credibility

How material selection, flow dynamics, temperature control and commissioning practices influence microbial and Legionella risk.

Software adoption has moved from being a competitive advantage to a core requirement — especially in the face of labor shortages, cost pressures and rising customer expectations.

Measuring the flow rate through a circuit has always been more of a challenge compared to measuring temperatures. Very few circuits are equipped with permanently installed flow meters.

In today’s technology-heavy plumbing and mechanical industry, “must-see” products aren’t just shiny new equipment, they’re solutions that help solve today’s labor constraints, reduce callbacks, and keep buildings running with fewer surprises.

Manufacturers exhibiting at AHR Expo 2026 are bringing forward solutions that prioritize intelligence, flexibility and practicality, addressing real-world challenges faced by contractors, engineers, distributors and building owners.

While the risk of Legionella exists across many types of buildings, healthcare and long-term care facilities are particularly vulnerable. These buildings often have large, complex plumbing systems with extensive pipe networks, variable water usage, and numerous fixtures, all of which can create conditions conducive to bacterial growth if not properly managed. As a result, even well-designed and well-maintained systems require ongoing attention to minimize risk.

All year, leadership is a fast-moving, day-by-day experience. But December's slower pace lets you take a step back, and that's when strategic thinking happens. An intentional leadership reset is a chance to reflect on what truly matters, refocus on the strategies that drive results, and reignite the performance, purpose, and passion that will carry you into 2026 with clarity and momentum.

Today, we still get calls about older systems. The potential customers often think their house or building is the oldest we have ever seen. I suppose people think every other building on their block has removed the old steam or hot water system and replaced it with something more modern.

Did you know that plumbing apprenticeships can be dated all the way back to the European medieval period? Back in the 1300s-1500s, Masters of trades would take on young, unskilled workers and teach them their craft in exchange for their indentured servitude, wherein they would work for years without pay while they honed their craft.
