This tech tip was heavily inspired by one aspect of Rick Sims’s 2021 HVACR Training Symposium session titled “Conductsation.” The entire presentation is worth a watch, but the advice in “Conductsation” and this tech tip are tailored to hot, humid climates. The contents of this tech tip may NOT work for colder climates. Dr. Allison […]

An important rating on motors is the AMBIENT  temperature rating at which the motor can operate. This rating refers to the temperature of the air around the motor, not the temperature of the motor itself or even the temperature of the outdoor air, since the motor is often in a condenser air stream that is at […]

I didn't install this unit. First off, attic installations are among my least favorite applications from the standpoints of serviceability, system longevity, and a laundry list of other items. Here in Florida, it's just a bad idea due to the high humidity and temperature in a vented attic and the condensation issues that can and […]

 In this live episode from the AHR 2026 Podcast Pavilion, Bryan sits down with Copeland's Josh Souders (Manager of Commercial Unitary Product Management) and Jeff Kukert (Compression Senior Technical Trainer) to dive deep into Enhanced Vapor Injection (EVI) technology and its transformative impact on HVAC systems. This conversation offers both technical professionals and industry […]

 In this informative episode, Josh Souders from Copeland joins Bryan to dive deep into heat pump technology, discussing everything from basic operations to advanced features in cold climate applications. The conversation begins with a fundamental explanation of how heat pumps work, describing them as essentially air conditioners with a reversing valve that allows them […]

 In this episode, Josh Souders from Copeland joins the HVAC School Podcast to discuss modulating and variable capacity technologies in HVAC systems. Josh provides an in-depth look at the different levels of modulation available in residential HVAC equipment, from traditional fixed-speed systems to two-stage, multi-stage, and true variable-speed compressors. The conversation covers the benefits […]
