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 […]

James Bowman talks to Bryan about leak sealant products, including RectorSeal's Leak Freeze product. James talks about how sealants work, what happens when they don't work, and how to be open-minded without being gullible. Leak sealants must not react adversely with the components inside a system (oil and refrigerant). Just as mineral oil caused some […]

In this episode, Bryan speaks with James Bowman from Rectorseal about hard start kits, PTCR devices, run capacitors, compressor overheating, and the Kick Start product. We also go pretty in-depth on potential relays and how they operate. Hard start kits are mechanical potential relays connected to a capacitor, and they aid in starting the compressor. […]
