Michael Faraday: Patron Saint of HVAC Technicians

Who was Michael Faraday—besides the guy we named the capacitor after? Well, actually, we named the measure of capacitance after him (the farad), but let’s not get all caught up in semantics. Faraday was a scientist who lived from 1791 to 1867. He was an experimental scientist who had little to no formal education but […]

Blower Fan Watt Draw Considerations for ECMs

I'd like to give special thanks to Steve Rogers from TEC for helping write this tech tip and sharing some helpful visuals. Thanks, Steve! ACCA Standard 310 introduced a grading protocol for HVAC systems. While HVAC practitioners won’t be the ones carrying out the tasks laid out in Standard 310, energy raters will conduct them […]

Tool Selection: Electrical Meters

I'd like to give a special thanks to Tony Gonzalez from Fieldpiece for providing technical guidance about the SC680's power measurement capabilities, as well as VAC and AAC measurements on ECMs. We’ve talked through specifications, applications, and features for a few tools, but none of them have been quite as hardcore as electrical meters. Like […]

Proper Design For Ductless and Ducted HVAC Systems

In this podcast episode, Bryan, Chad, John, and Allison discuss proper design for ductless and ducted HVAC systems, especially mini-splits. They also discuss potential future improvements to equipment and duct designs. Mini-splits are smaller than traditional HVAC units, so they make zoning a bit easier. However, load calculation plays a huge role in equipment selection […]

Friction Rate and Duct Design w/ Dr. Bailes (Podcast)

This episode is very exciting to me because we get to have Dr. Allison Bailes on the show. Today, he shares his knowledge about friction rate and duct design. Allison got his start teaching college-level physics before getting into the building design industry. If you have a forced-air system that blows heated or cooled air […]
