In this episode of HVAC Know It All, host Gary McCreadie talks with Tyler Nelson, Master HVACR, HVAC Sales Manager & Trainer - Americas at Seitron Americas Inc., about heat exchanger inspections, combustion diagnostics, and personal carbon monoxide monitoring. They explain how visual checks complement analyzer readings, why building changes can disrupt draft, and how technicians can approach CO protection throughout the year.
Tyler conducts training for contractors, distributors, and conference audiences. His work includes helping contractors improve installation, commissioning, and diagnostic practices. He brings that field-training perspective to inspection access, interpreting combustion measurements, and using technology without abandoning hands-on diagnostic skills.
Key Takeaways
How ambient CO monitoring, installation checks, visual inspection, and combustion analysis work together as layers of a diagnostic process.
How borescopes, phone cameras, and planned access panels can help technicians inspect hard-to-reach heat exchangers.
Why a blue flame alone cannot establish safe combustion performance.
How building alterations and exhaust systems can change pressure conditions and interfere with appliance draft.
Why personal CO monitoring remains relevant during summer service calls when other fuel-fired appliances are operating indoors.
