Legionella is making headlines - but what is it, how does it spread, and what can our industry do to prevent it?In this episode of MechBiz Studio, Adam Hedden and Matthew Reid are joined by Aaron Besseling (ASHRAE Hamilton) and Kevin Cherewaty (Heavy Cooling Tower Services) to discuss a recent Legionella outbreak, cooling towers, potable water systems, ASHRAE Standard 188, and the responsibilities of contractors, engineers, and building owners.The episode also features a live rapid Legionella test on an operating cooling tower, with results that took everyone by surprise.If you work in HVAC, plumbing, hydronics, or building maintenance, this is a conversation you won't want to miss.

Adam Gordon, Director of Plumbing at Orella Group, joins Adam Hedden and Matthew Reid to discuss how social media helped shape his plumbing career, the importance of mentorship, leadership in the trades, and why contractors need to stop ignoring the power of personal branding. From learning hydronics through online influencers and industry experts to building a following of his own, Adam shares practical insights on education, problem-solving, training apprentices, and creating authentic content that resonates with today's workforce.

The conversation also covers:

• Training and mentoring the next generation of tradespeople

• Leadership and problem-solving in the field• Building an authentic social media presence

• The growing role of online education in the trades• Industry trends, heat pumps, and trade show networking

• The unforgettable story of a kitten rescue that unexpectedly landed Adam in the news

Hosts Adam Hedden and Matthew Reid dive into the world of domestic hot water systems - breaking down where hot water is actually used, how systems are sized, and why oversizing is one of the industry’s most common mistakes. From tank vs. tankless vs. indirect systems to real-world examples of high-demand homes, they explore how proper planning, fixture counts, and understanding peak demand can make or break a system. The conversation also covers heat pump water heaters, recirculation systems, water quality challenges, and maintenance realities that impact performance and longevity. If you get domestic hot water right, no one notices - but if you get it wrong, you’ll never stop hearing about it.

MechBiz Studio Launch | Hybrid HVAC Systems, Amendment 15 & Trade Show Season

Welcome to the first episode of MechBiz Studio, the new video podcast from Mechanical Business focused on the people, technology, and trends shaping the HVAC industry.Hosts Adam Hedden and Matthew Reid kick off the series by introducing the podcast and sharing what listeners can expect from future episodes – real conversations about HVAC trends, system design, regulations, and the evolving mechanical industry.In this launch episode, the discussion explores the growing adoption of hybrid HVAC systems, where gas equipment, electrification, heat pumps, and heat recovery technologies are being designed to work together. Instead of a single solution, modern mechanical systems are increasingly combining multiple technologies to meet efficiency targets while maintaining comfort for the end user.The conversation also touches on the impact of Amendment 15 efficiency changes, which came into effect January 1, 2025. These new requirements are pushing more commercial heating equipment toward 90%+ efficiency and condensing designs, creating new challenges for system designers when balancing temperature requirements, equipment selection, and system performance.Beyond the technical discussion, Adam and Matthew share updates on their careers, talk about the close-knit nature of the HVAC industry, and look ahead to the upcoming trade show season including CMPX in Toronto, the MEET Show in Atlantic Canada, and other regional events.
