Adam, Casey, and John break down the often-overlooked side of indoor air quality—how some IAQ devices can actually create harmful byproducts in your home. They explore the pros and cons of different filtration types, when to use each, and why not all “clean air” products are created equal. If you care about what you’re customers are breathing, this episode will help you make more thoughtful recommendations.

Adam, Casey, and Mark swap some wild (and a little scary) stories about the surprising places carbon monoxide can show up. They chat about the risks of not testing, what the Wanton Act means for liability, and why ignoring it isn’t worth it. Technician safety should always be a concern, so they share simple, real-world tips on how to start protecting yourself and your customers from this silent danger.

Adam and David discuss field conditions and factors that affect comfort and performance. They examine why design doesn’t always equal reality and the risks of ignoring proper sizing and selection. The dangers of oversized equipment and how it affects both the duct system and comfort are also discussed. They share simple tips to estimate field delivered equipment and system capacity to troubleshoot problem jobs and three steps you can use to identify the real source of comfort and performance complaints.

Adam and David share their recent field experiences testing NCI’s ComfortMaxx powered by measureQuick. They discuss testing challenges, like fan airflow measurement, zoned systems, the importance of processes and checklist, and why you should label your smart probes. Their discoveries highlight the differences between the HVAC equipment and system and how the oversized equipment performed like it was the right size.

Adam Mufich and Dominick Guarino of National Comfort Institute talk with Steve Rogers and Chris Hughes of The Energy Conservatory about the Air Upgrade™ process and how that has changed the path of airflow testing. Testing is at the center of it.

The group shares how the three most common problems are Airflow Airflow Airflow. According to Chris Hughes, a long-time student of NCI, “airflow is the least taught subject in trade school, and it all starts with a deeper understanding of static pressure.” Chris and Steve Rogers share how TEC’s Trueflow app dovetails with NCI training, and how each of the three NCI tests work TEC’s tools and software.

Today’s Heat Pumps are not your grandad’s Oldsmobile. David Richardson brings together some champions of heat pump retrofits to talk about their experiences with them – including a teaser for a new upcoming NCI class! The key to good heat pump installations, whether a replacement or converting to electric heating from fossil fuels is understanding how the whole system works together, especially air distribution.

It starts with understanding the true building load, using a good load calc software. Next you select the right equipment to match the existing conditions, and updating the duct system to allow the equipment to deliver the performance it was designed to. The key is to understand a heat pump is not a system – it’s a component of a system.

Equipment selection is more important than ever especially in cooling mode when you need to balance latent and sensible heat removal. Selecting the right inverter equipment is even more critical in latent removal.
