Description:

Looking to heat or cool a guest suite, workshop, or tiny home—without hiring an HVAC tech? This 18,000 BTU MRCOOL DIY mini split makes it easy.
The 4th Gen MRCOOL DIY 18K Mini Split is built for folks who want serious efficiency, quiet performance, and total climate control without paying a pro. With 22 SEER efficiency, it’s Energy Star certified and powerful enough to keep up to 750 square feet cool in the summer and warm through winter—even down to -13°F.

Best part? It’s truly DIY. The 25-foot Quick-Connect line set is pre-charged with refrigerant, so you can install it yourself with basic tools. No licenses, no refrigerant handling, no hassle.

Control it from your smartphone, adjust the temp based on your remote’s location, or set it to SLEEP and let it coast while you rest easy. For cabins, additions, garages, and off-grid setups, this system’s a game-changer.

Why It Stands Out:

DIY-Friendly Setup – 25 ft pre-charged line set lets you install in a few hours with no special tools
Efficient & Affordable – 22 SEER rating for serious savings without sacrificing comfort
Year-Round Comfort – Operates down to -13°F for true four-season heating and cooling
Smart Control Ready – Compatible with iOS/Android via the SmartHVAC app
Follow Me Feature – Adjusts temp based on where you’re standing with the remote
Quiet Operation – Runs as low as 31 dB—quieter than a library
Gold Fin® Protection – Corrosion-resistant condenser built for coastal or harsh climates
Backed by Warranty – 7 years on the compressor, 5 years on parts, lifetime option with registration
