  • Which Testo Analyzer Fits Your Work, the 320 or 330? - Part 2

    Which Testo Analyzer Fits Your Work, the 320 or 330? - Part 2
    2026/10/29
    In this episode of HVAC Know It All, host Gary McCreadie talks with Jamie Chadwick, HVAC Product Manager at Testo Instruments - North America, about combustion analysis and technician safety. They discuss the 320 and 330 analyzers, sensor maintenance, digital reporting, and personal carbon monoxide monitoring. Technicians will learn how clean-air zeroing, annual service, and gas path checks support reliable testing. Jamie teaches combustion analysis across furnaces and boilers using natural gas, propane, and oil. His classroom experience highlights practical mistakes, including zeroing near vehicle exhaust and leaving condensate-trap plugs loose. He connects those examples to equipment checks and the need to consult local codes and manufacturer specifications. Key Takeaways How combustion readings provide a reference point for evaluating operation alongside local codes and manufacturer specifications. Why field-replaceable sensors do not eliminate the need to send an analyzer in annually to verify its operation. How digital reports preserve dated and timestamped readings and let technicians share test records with customers and the office. How a wearable CO detector with an earbud option can support personal monitoring in loud mechanical rooms. Why zeroing an analyzer in clean outdoor air, away from running vehicles and cigarette smoke, helps prevent distorted readings. How a gas path check helps identify leaks that warrant checking hose connections, filter caps, and the condensate-trap plug.

  • The Contractor Experience Behind Amply's HVAC Software

    The Contractor Experience Behind Amply's HVAC Software
    2026/10/28
    In this episode of the HVAC Know It All Business Edition Podcast, co-hosts Gary McCreadie and Furman Haynes from WorkHero continue the conversation with Eric Fitz, Co-founder, Co-CEO, and Chief Technology Officer at Amply Energy, Inc., and Ed Smith, Co-founder, Co-CEO, and Chief Customer Officer at Amply Energy, Inc., about the operational demands of heat pump work. The discussion covers rebate paperwork, cash flow, subcontractor partnerships, and the opportunity to combine HVAC with whole-home performance services. Eric and Ed explain how contractors can pair technical expertise with reliable processes to compete on trust rather than speed, and how design software and human-supervised AI could support that work. Eric and Ed draw on experience with installations, whole-home electrification services, and software development at amply. Their work connects building-envelope assessment, HVAC design, electrical-load considerations, and customer recommendations. They describe a design-focused approach to software development, with tools intended to support contractors' judgment rather than replace their responsibility for the results. Expect To Learn: -How rebate administration and delayed reimbursements can strain staffing, cash flow, and payroll. -Why electrical and weatherization partnerships need shared standards for quality, communication, and customer service. -How combining building-envelope improvements with HVAC design supports a whole-home approach to comfort and efficiency. -Where design software could connect insulation, electrical-panel assessments, energy forecasts, and phased customer recommendations. -How the trust matrix pairs strong processes with technical expertise to distinguish independent contractors from speed-focused competitors. -How to improve pricing, quoting, and operations incrementally without sacrificing craftsmanship or customer trust. -Why amply's approach to AI keeps humans responsible at the beginning and end of the workflow.

  • Skipping the First Combustion Test Costs You a Baseline - Part 1

    Skipping the First Combustion Test Costs You a Baseline - Part 1
    2026/10/26
    In this episode of HVAC Know It All, host Gary McCreadie talks with Jamie Chadwick, HVAC Product Manager at Testo Instruments - North America, about putting safety first during heating service and maintenance. They explain testing before and after repairs, recognizing possible carbon monoxide exposure, preparing an analyzer, and selecting a sampling location. Technicians will learn how these practices support safer testing and help document their work. Jamie draws on his contracting experience and current training work to connect analyzer procedures with field conditions. His approach emphasizes checking equipment before making changes, verifying operation afterward, and recognizing when emergency services need to make a site safe. He also explains why general training cannot replace checking local codes and manufacturer requirements. Key Takeaways How testing before and after service helps document equipment condition and demonstrate the effect of maintenance. Why reported headaches, lightheadedness, or nausea warrant attention to possible carbon monoxide exposure and personal CO monitoring. Why suspected hazardous CO conditions call for evacuation and emergency assistance rather than attempts to continue troubleshooting. How zeroing an analyzer in clean outdoor air and allowing equipment operation to stabilize helps prepare for combustion testing. Why sampling location matters for flue temperature and efficiency readings, and why an outdoor termination reading may not match a reading near the appliance.
