Cooling It with Mike: Time to Talk Energy Savings
Hey there, Mike Sanders here. If you’re like most homeowners I talk to, you’ve heard folks tossing around terms like "energy-efficient refrigerant" or "R-32 lowers your bills" without explaining why or how. So today, I’m laying it out straight: how R-32 air conditioners actually save you money—and what to look for in a system.
First Things First: What Is R-32?
R-32 is a newer refrigerant that’s replacing R-410A in many HVAC systems. It has a Global Warming Potential (GWP) of 675, which is about one-third the GWP of R-410A (2,088). That’s good for the planet, sure—but what about your wallet?
Turns out, R-32 systems are more efficient. They cool better using less power. And that leads to lower monthly bills.

The Real Math: SEER2 Ratings and Energy Savings
Let’s get into the numbers. A unit’s SEER2 rating tells you how efficiently it cools over a typical season. The higher the number, the better.
The Goodman 2.5 Ton 14.5 SEER2 R-32 System is a perfect example. It uses R-32 and meets the newer 2023 federal efficiency standards. Compared to older 10 SEER systems, you could save 20% to 30% on your cooling costs each year.

How R-32 Helps Boost System Performance
R-32 isn’t just a more eco-friendly refrigerant—it’s also a better thermal conductor. That means:
-
It transfers heat faster
-
It requires less refrigerant per system
-
It allows the compressor to run more efficiently
That faster heat exchange means quicker cool-down times and less work for your compressor, which adds up to less electricity consumed per hour of use.
Real-World Scenario: Summer Cooling Costs
Let’s say you live in Phoenix, AZ, where your A/C runs most of the year. Upgrading from an old 10 SEER system to a 14.5 SEER2 R-32 system could cut your annual cooling costs from about $1,200 to $840. That’s $360 in savings each year.
And that doesn’t include any utility rebates, which many states now offer for high-efficiency, low-GWP systems.
Bonus: Lower Maintenance and Longer Lifespan
R-32 systems often experience less wear and tear due to lower operating pressures and improved heat transfer. That means fewer service calls, fewer part failures, and a longer lifespan for your investment.
Plus, most R-32-compatible systems are built with newer tech—like ECM blower motors and advanced diagnostics—that make them easier and cheaper to maintain.
Final Tips from Mike
Here’s the bottom line:
-
Yes, R-32 air conditioners save money.
-
The savings come from better heat transfer, more efficient operation, and higher SEER2 ratings.
-
A quality install matters just as much as the unit. Work with pros who understand R-32 systems.
Want to future-proof your cooling and shrink your electric bill? A unit like this Goodman R-32 system is a smart bet.
Until next time, stay cool, – Mike Sanders
