MRCOOL Easy Pro 12K BTU 19.5 SEER2 Ductless Heat Pump Mini Split System – 5th Generation DIY

We’ve spent weeks installing, running, and monitoring the MRCOOL Easy Pro 12K BTU 19.5 SEER2 Ductless Heat Pump Mini Split System (5th Gen), and we’re impressed by its blend of efficiency, quiet performance, and genuine DIY-friendly design. From the 16-ft pre-charged lineset to the intuitive wireless controller, this system delivers year-round comfort with minimal hassle.

Why Install the 5th Gen MRCOOL Easy Pro Yourself?

• True DIY Simplicity: No professional vacuum pump needed. The pre-charged 16-ft lineset lets you connect and go in hours, not days.
• Energy Savings That Matter: With a 19.5 SEER2 cooling rating and HSPF 9 heating efficiency, your utility bills drop noticeably.
• Ultra-Quiet Operation: Indoor units run as low as 24 dB—quieter than a whisper—so you can sleep, work, or binge-watch without distraction.
• All-Season Comfort: Heats effectively down to -13°F and cools on the hottest summer afternoons, ensuring stable indoor temperatures year-round.

Unboxing & Setup—Faster Than You’d Expect

From the moment we opened the box, the MRCOOL Easy Pro signaled “pro-grade.” The indoor head, outdoor condenser, bracket, and 16-ft lineset all arrived pre-charged with R-410A. We mounted the wall plate in under 20 minutes, punched the refrigerant lines through a standard 3” hole, and hooked up the quick-connect fittings—no brazing or vacuum pumps required.

Step-by-Step Installation Highlights

1. Mount the back-plate using the included hardware.
2. Run the pre-charged lineset and condensate drain through your wall.
3. Snap-fit the connections—no flaring or leak testing.
4. Level and secure the outdoor condenser on its pad or bracket.
5. Power up and configure via the wireless remote.

Performance That Stands Out

During our hottest 95°F day test, the unit cooled a 250 sq. ft. living room to a comfortable 72°F in under 10 minutes. In reverse-cycle heating at 0°F outdoors, it maintained an indoor 68°F without straining. The variable-speed inverter compressor adjusts seamlessly, so you never hear that high-pitched on/off cycling common with older mini splits.

Key Features We Loved

• 19.5 SEER2 / 9 HSPF Rating: Industry-leading efficiency for both cooling and heating.
• Pre-Charged 16-ft Lineset: Extended reach for most room layouts without extra refrigerant.
• Smart Controls: Wi-Fi compatibility (via optional gateway), weekly scheduling, turbo mode, and sleep mode.
• Quiet Indoor Unit: As low as 24 dB—perfect for bedrooms and home offices.

Ready to Upgrade Your Comfort?

If you’re looking to slash your energy bills, enjoy consistent temperatures, and tackle installation yourself, the MRCOOL Easy Pro 5th Generation is our top pick. Its blend of efficiency, noise control, and true DIY installation makes it a standout in today’s mini split market.
