Hey, it’s Tony again. You’ve probably seen mini-split systems (those sleek indoor wall units) in a neighbor’s house or online. And you might be wondering:
“Can I go ductless with R-32? And should I?”
The answer? Yes, you can—and in a lot of cases, you probably should. Let’s talk about what ductless R-32 systems offer, and how they compare to central air setups.
🌬️ 1. Ductless R-32 Systems Are Ideal for Zoned Comfort
One of the biggest benefits of ductless mini-splits is room-by-room temperature control. You can cool the living room to 72°F and the bedroom to 68°F—no duct losses, no overcooling.
And since R-32 systems operate with inverter-driven variable speed compressors, they adapt to changing loads efficiently and quietly.

💸 2. Major Energy Savings in Homes Without Ducts
If your home is older, has baseboard heat, or lacks central ducts, going ductless avoids costly retrofitting. According to ENERGY STAR, duct losses can account for 20–30% of energy consumption in central systems—especially if the ducts run through unconditioned attics or crawl spaces.
Ductless R-32 units eliminate those losses, translating into real savings.

🛠️ 3. Easier Installation + Greater Design Flexibility
R-32 ductless systems are typically faster to install and more flexible in layout than central air. No ducts means no major ceiling or wall demolition.
-
Great for additions, garages, sunrooms, basements
-
Ideal for homes with mixed-use zoning or rental units
-
Indoor units come in wall, ceiling cassette, or floor-mount options

🌱 4. R-32 Is the Leading Refrigerant in Ductless Systems Globally
R-32 is already the default refrigerant in ductless systems throughout Europe and Asia, and U.S. adoption is rapidly accelerating due to its:
-
68% lower GWP than R-410A
-
Higher efficiency with less charge volume
-
EPA approval under SNAP Rule 23
If you're thinking long-term, R-32 ductless keeps you compliant and ahead of future regulatory changes.

✅ Tony’s Takeaway
If you have limited ductwork or just want hyper-efficient, room-based cooling, ductless R-32 is an awesome option. You’ll get zoned comfort, faster installation, and energy savings without sacrificing environmental performance.
