In this episode of @escogroup Esco HVAC Podcast, Clifton Beck is joined by Phillip Kriegbaum, Senior Business Development Manager, and Terry Frisenda, Executive Sales Manager at LG, to discuss the future of HVAC education, modern installation practices, and the evolution of inverter-driven technology.
They explore how HVAC contractors and educators can adapt to new industry standards, from heat load calculations to flaring best practices, leak prevention, and condensate management. With the HVAC landscape rapidly evolving, Phillip and Terry provide insights into why training, proper installation techniques, and manufacturer-supported education are critical for success.
Key Takeaways:
The Shift Toward Inverter-Based Systems - LG’s inverter-driven HVAC technology enhances efficiency by adjusting capacity based on demand, improving energy savings and system performance.
Proper Flaring & Torquing are Critical - Many system failures stem from poor flare connections. Using the right tools and manufacturer-recommended torque specifications is essential for leak-free installations.
Accurate Load Calculations are a Must - Outdated sizing methods lead to inefficiencies. Modern heat load calculations and digital tools ensure optimal system performance.
Leak Detection & Evacuation Standards - Proper pressure testing at 550 PSI with nitrogen and digital vacuum measurement can prevent costly refrigerant leaks before startup. Skipping this step leads to long-term system failures.
Ductless & Whole-Home HVAC Solutions - LG’s solutions extend beyond mini-splits, offering ducted and ductless systems for energy-efficient whole-home heating and cooling.
Condensate Management in HVAC Systems - Proper drainage, manufacturer-specified PVC lines, and understanding condensate lift mechanics help prevent water damage and system failures.
The Importance of Training & Education - HVAC professionals must evolve with technology by adopting modern tools, digital diagnostics, and manufacturer-led training to stay competitive.
Noteworthy Quotes:
"We need to bring back skill in the trade. The HVAC industry can no longer afford sloppy installations." - Terry Frisenda
"The biggest problem with modern HVAC systems isn’t the technology-it’s improper installation." - Phillip Kriegbaum
"If you don't pass your leak test, don't move forward. Every installation step must be verified." - Terry Frisenda
"Digital gauges changed everything. If you're still relying on analog, you're missing critical details." - Phillip Kriegbaum
"HVAC education is evolving. It's time to rethink training and installation practices." - Clifton Beck

Good and informative show . Thanks again.
You are very welcome, we’re glad you joined us.
Most of my business is trouble shooting sick systems. And most are relatively new installations. I applaud ESCO and other training industries for their efforts in bringing in new technicians to the forefront of this era's technology but when company owners drive those same technicians into the ground by restricting them to limits on their time for new or replacement installations there is no room for intelligent training of minds that are starving for that wisdom and pride that comes from continuous training in the classroom and on the job. Pretty much all I see in the field of all forms of HVAC/R is the drive to install and/or replace on a restrictive time basis. The install and service technicians are given no chance to actually understand and enjoy their works of art as the emphasis, through most of the owners, is centered around the bottom line, getting the money and moving on. It's a shame but that is the way this new world seems to be.

Thanks for joining us!
Residential HVAC is gonna follow and copy the same demise and problems as Automotive started doing back in the early 1990s.,
As you reduce refrigerant charge like you stated crucially charged, and it will show up faster with customer discomfort.,
The other problem that will be happening this will happen more often on the same system. That means to compressor more often runs extremely low on refrigerant to oil return to the compressor.. and the compressor will be running more often through its lifetime at high super heat overheating. Automotive went through the same problem. Compressor start dying more often..
The other negative affect that residential commercial have already started to notice with the advent of microchannel condensers thinner, copper thinner aluminum is even more heat exchanger leaks.
In our automotive industry, they went to the second date generation of ultra high, efficiency, micro channel design. With even smaller internal fins and tube diameters even thinner because thinner is cheaper.. thinner more energy transfer.
And a lot more leaks.
If residential and commercial heat exchangers migrate over to using the more ultra high efficiency, micro channel designs just like residential land commercial started to do using the 1990s technology automotive in residential and commercial.
If you think you see a lot of of evaporator and condenser leaks now. Wait until you see the move to the new ultra high efficient, micro channel heat exchanger..
Not to even start to mention when compressor fails on a scroll due to lack of lubricant, and those very tiny metal particles go into the outdoor condenser directly from the compressor. The ultra small tube opening inside the refrigerant tubing of the micro channel gets partially restricted with the ultra small tiny metal particles that are ejected from the compressor..
And we’re gonna have technicians thinking they only need to change compressors when they have condensers that are partially restricted, and you cannot flush out the new generation of ultra high-efficiency micro channel.
Welcome to the future of more problems and higher expenditures to the customers.
We'll be exploring these issues and solutions in future videos, so stay tuned!
