Psychrometrics and the Magic Line - Short #265

HVAC School - For Techs, By Techs ·

2025/11/11

In this short podcast episode, Bryan talks about psychrometrics and the magic line inside a messy-looking chart. The psychrometric chart is a key tool for understanding the relationship between air and water. "Psychrometric" comes from the Greek roots for "cold" and "measurement." As such, a tool called the psychrometer (with paired wet-bulb and dry-bulb thermometers) could measure two different temperatures, and we could use these to determine how much water vapor the air can hold (even though the

How Duct Tape Got Its Name (and Why It Shouldn't Be...

HVAC School - For Techs, By Techs ·

2025/11/04

In this short podcast episode, Bryan explains how duct tape got its name and why it shouldn't actually be used on ducts. Duct tape is a versatile home DIY-fix tool, but despite its name, it wasn't initially made to seal ducts at all. In 1943, we were in the thick of World War II, and ammo shipments were sealed with wax and paper tape. These were often not durable or difficult to open. Johnson & Johnson developed a tape with rubber adhesive on a cotton duck cloth backing (which was already widely

2025/10/21

In this short podcast episode, Bryan explores an interesting story in the history of HVAC: how air conditioning saved the movies. In the summer of 1925 in NYC, a new film was set to appear on the big screen... but the theater was stuffy with no fan that could cool down the sheer mass of people packed into the room. People were uncomfortable, and theater attendance plummeted in the summer. The movie industry struggled to fill seats in the summer. Willis Carrier, who had solved humidity problems in

HVAC School - For Techs, By Techs ·

2025/10/14

In this short business-oriented podcast, Bryan breaks down the differences between three commonly confused positions/roles: analyst vs. PM (project management) vs. operations. When you own or work in a small business, you might wear a lot of hats: estimating, writing proposals, troubleshooting, being a customer or coworker's therapist, etc. This work can be organized, and problem-solving roles include analysts, project managers (PMs), and directly responsible individuals (DRIs).

The Hidden Cost of Killing Radiant Load - Short #260

HVAC School - For Techs, By Techs ·

2025/10/07

In this short podcast, Bryan talks about the hidden cost of killing radiant load, especially when it comes to installing radiant barriers in attics. We sometimes get service calls about ducts sweating when they never used to sweat. If there are no problems with the system (i.e., the refrigerant charge, static pressure, airflow, supply air temperature, and blower speeds are all good), this type of situation can be a head-scratcher. Ask a customer if they've made any changes to the attic or equipment

Dehumidify with a Waterfall? - Short #259

HVAC School - For Techs, By Techs ·

2025/09/30

In this short podcast episode, Bryan talks about history and HVAC science: how to dehumidify the air with a waterfall and how cold water became the first air conditioner. In 1902, Willis Carrier worked for a printing company in Brooklyn, New York. There was a huge humidity problem during the summer: the printing plant got damp, causing paper to swell and ink to smudge. Carrier realized that he could wring water out of the air if he brought the air's temperature below the dew point. His solution was

Static Pressure is like Blood Pressure - Short #258

2025/09/23

In this short podcast episode, Bryan explains the science behind a common HVAC simile: static pressure is like blood pressure. He covers the similarities and differences between measuring static pressure during a service call or maintenance and a doctor measuring your blood pressure at a checkup. Total external static pressure (TESP) should be measured every time you perform service or maintenance on a unit. The exact test port location will vary between air handlers and furnaces; the coil adds

Non-bleed TXVs and Hard Starts - Short #257

HVAC School - For Techs, By Techs ·

2025/09/16

In this short podcast episode, Bryan talks about non-bleed TXVs and whether they need hard starts. A non-bleed (hard shutoff) TXV is a metering device that shuts off during the off cycle; it closes shut when there is no superheat. This strategy prevents refrigerant migration, especially in cases where we have long line sets. Liquid refrigerant stays in the condenser and is kept out of the evaporator, suction line, and compressor crankcase. When we have a non-bleed TXV, the compressor may have a hard

Leaky Ducts = Sweaty Houses - Short #256

HVAC School - For Techs, By Techs ·

2025/09/09

In this short podcast episode, Bryan explains how leaky ducts can lead to sweaty, uncomfortable houses. Moisture issues are common all across humid and "green-grass" climates in the United States. Hot, unconditioned attics and crawl spaces also often have high dew points, which can cause moisture problems in those spaces. Plants also release moisture, so agricultural communities also have those special considerations. There are several HVAC and building design factors that can prevent or worsen
