UEI at AHR: Carbon Monoxide Safety and Combustion Analysis Mar 03, 2025

Show notes

In this informative podcast episode, Bryan from HVAC School is joined by Louise Keller, the National Training Manager for UEI Test Instruments, to discuss the critical importance of carbon monoxide safety and proper combustion analysis. The conversation begins with lighthearted banter about the previous night's Tactical Awards ceremony before diving into the serious topic of CO dangers and detection.

Louise shares valuable insights about the dangers of carbon monoxide exposure, particularly at lower levels that might not trigger standard home CO alarms. She explains that CO poisoning can mimic many other conditions, including early-onset Alzheimer's, traumatic brain injury, and mobility issues. Bryan adds historical context by recounting how many Victorian-era "ghost stories" and fainting episodes coincided with the introduction of gas lighting in homes, suggesting these phenomena were likely CO poisoning symptoms. He also shares the little-known story of Walt Disney's parents, who tragically died from carbon monoxide poisoning in a house that Disney built for them.

The discussion shifts to practical applications, with Louise explaining the proper use of combustion analyzers and the importance of regular recertification. They emphasize that visual inspection alone is not sufficient for safety, and proper testing is essential for both client safety and equipment efficiency. The conversation concludes with information about UEI's ServicePlus Guaranteed program, which offers extended warranty coverage, same-day recertification turnaround, transparent pricing, and convenient shipping for analyzers.

Key Topics Covered:

The dangers of carbon monoxide as an odorless, colorless, and tasteless gas
How low-level CO exposure can cause serious health issues that mimic other conditions
The limitations of standard home CO alarms, which typically won't trigger until reaching 70 PPM for 1-4 hours
Proper combustion analyzer startup procedures (starting outside in fresh air)
The importance of checking all combustion appliances in a home (furnaces, water heaters, ovens, etc.)
Best practices for comprehensive testing, including "appliance sweep tests"
Historical context of CO poisoning, including connections to Victorian ghost stories
UEI's ServicePlus Guaranteed program for analyzer recertification and warranty extension
The importance of regular recertification to ensure accurate readings and maintain warranty coverage
Tips for helping clients schedule regular maintenance and safety checks

Static Mistakes - Short #232 Feb 25, 2025

Show notes

In this short podcast episode, Bryan covers some common mistakes when measuring static pressure. Static pressure is balloon pressure, not CFM or velocity pressure, but it can be an airflow indicator. The best way to start learning about static pressure is to start measuring total external static pressure.

Gas furnaces and heat pumps are different; static pressure is rated at the furnace in the former (not the cased coil, which is additional), and the static pressure includes the coil in a heat pump. The highest static pressure will always be at the blower, but restrictions on either side of the blower will raise static pressure on both sides of the blower.

Dirty components can drop the total external static pressure, which is a common point of confusion that can lead to misdiagnosis. You'll want to determine static pressure at the blower and across components. If you want to determine if a cased evaporator coil is clogged, you can measure the static pressure drop across the coil (by measuring below and above the coil) and compare it to the manufacturer's specifications. Dirty blower wheels can also cause problems, as they don't move much air in the first place.

Lower static pressure at the blower is the best for amp draw and airflow, and our system designs and accessories can support low static pressure. Dialing in airflow, putting your probes in the right positions when you measure static pressure, proper register and grille selection, and minimally restrictive filters all go a long way.
