When your own president chooses a product for his personal home, you know it’s something special.
That’s exactly what happened when AC Supply President Randy Boyd upgraded the HVAC system at his family’s lake house in Granbury, Texas — replacing an aging R22 unit with the all-new LG CV R32 Unitary System.
The results were immediate, dramatic, and a real-world example of what today’s contractors can expect from LG’s newest innovation.
This Granbury installation serves as a powerful case study for HVAC contractors across Texas. Not only does it showcase LG’s next-generation inverter technology and R32 refrigerant, but it also demonstrates how easy this system is to install in real replacement scenarios.
The Challenge: An Outdated R22 System and a Difficult Install Layout
The home was built in 1969 and still housed an old R22 system that was struggling to keep up with Texas heat. The ductwork and layout created additional challenges:
-
The air handler sits dead center in the middle of a two-story home.
-
Running new wire from the outdoor unit to the indoor space would be extremely difficult.
-
The homeowners needed better upstairs comfort and improved humidity control.
It was the perfect real-life test for LG’s new CV R32 Unitary line.
The Solution: The New LG CV R32 Unitary System
An install-friendly, homeowner-approved upgrade.
The AC Supply installation team replaced the old R22 unit with a high-efficiency LG CV R32 outdoor unit paired with a multi-position air handler. According to the installation team and the homeowners, the system exceeded expectations.
The biggest surprises?
✔ Existing thermostat wire was fully compatible. No need for costly rewiring or major labor.
✔ Multi-position AHU design simplified the install. Works horizontally in attic spaces or vertical in closets.
✔ R32 refrigerant and inverter performance delivered major efficiency gains.
✔ Line set replacement wasn’t required in this case.
As the installers noted, these features make LG’s new unitary line “a game changer” for replacement installs.
Quiet, Comfortable, Energy-Efficient: The Homeowner Experience
Once the system was running, the immediate benefits were obvious.
1. Whisper-Quiet Operation
LG is known for exceptionally quiet inverter technology, and this system continued that reputation. The homeowners described it as “very, very quiet”—a noticeable improvement from the older system.
2. Strong Humidity Control
One of the standout features was humidity performance.
The smart thermostat displayed relative humidity at around 50%, resulting in a dramatically more comfortable living environment — especially important in Texas summers.
3. Enhanced Comfort Upstairs
Like many two-story homes, the lake house had typical heat-gain issues upstairs.
To solve this, the team added a supplemental LG multi-zone system for the second floor. The result was balanced comfort throughout the entire home.
4. Improved Energy Efficiency
LG’s inverter outdoor unit doesn’t run at fixed speeds like traditional systems.
It ramps in 1-degree increments, delivering smoother, smarter, and far more energy-efficient heating and cooling. As the homeowner said:
“Amazing technology — and LG is a leader in that.”
Why Contractors Are Excited About the LG CV R32 Line
This case study highlights why the new LG unitary line is getting so much traction among contractors:
➤ Faster, simpler installs
Because the system can use existing wiring and flexible AHU configurations, labor is reduced and retrofit jobs become more profitable.
➤ Easier-to-sell technology
LG is one of the most recognized consumer brands in the world—homeowners trust it.
➤ Quiet and energy-efficient performance
Homeowners immediately notice the comfort upgrade, making the system easier to recommend.
➤ Smart inverter control

Why R32 Matters: Cleaner, Cooler, Smarter
LG’s adoption of R32 refrigerant is a major step forward in modernizing the U.S. unitary market.
R32 offers:
-
Lower global warming potential (GWP)
-
Higher energy efficiency

Future-proof refrigerant compliance
The industry is moving this direction fast—and LG is leading the way.
