Gas Pool Heater Components and Common Issues

I know, I know. You came here for HVAC content, so why are we talking about pool heaters? Since we live in Florida and don’t have that much of a heating season, we have to look for other forms of work during the winter months. Pool heaters fit the bill quite nicely since they’re actually […]

The Chemistry of Combustion In the Wild

If you’ve been following my writing for the last couple of years, you know that I like to blather on and on about combustion analysis. Now, I am by no means an expert on the subject, as I live in North Texas (which is not known for its intense heating season), but I love using […]

Why Discharge Line Temperature is a Useful Reading

I’d like to give special thanks to Roman Baugh for the section about compressor superheat. It’s not something we talk about very often outside of chiller and commercial refrigeration applications, but it definitely has value in the HVAC world as well. Thanks, Roman! Since I started in the trade, we would take discharge line temperature […]

Ventilation and 62.2 Intro & Rant w/ Genry Garcia

Genry Garcia joins the podcast to give an intro to ASHRAE Standard 62.2. He and Bryan also share a nice rant about accountability in HVAC design. Standard 62.2 is the ventilation standard for low-rise residential buildings, which dilutes airborne contaminants like VOCs and CO2. Before coming up with a ventilation strategy, we need to […]

Blower Doors Don’t Need to Be So Confusing w/ Genry Garcia

Genry Garcia returns to the podcast to talk about blower doors and why ACH50 may needlessly complicate efforts to tighten a building envelope. A large element of indoor comfort comes down to controlling the load, especially the latent load. Even though we can control indoor humidity sources, we may also deal with infiltration, which contributes […]
