MRCOOL DIY Easy Pro 12K 12,000 BTU 19.5 SEER2 Ductless Mini Split Air Conditioner and Heat Pump - 115V

The MRCOOL DIY Easy Pro 12K 12,000 BTU 19.5 SEER2 Ductless Mini Split Air Conditioner and Heat Pump is a single-zone system that cools and heats spaces up to 550 square feet on standard 115V household power. It pairs a wall-mounted air handler with a compact outdoor condenser, and because it is a true heat pump, one unit covers both summer and winter.

This is a genuine DIY install. The Easy Pro ships with a pre-charged Quick Connect line set, so there is no vacuum pump, no gauges, and no special tools or refrigerant certification. Hang the air handler on the included bracket, set the condenser, tighten the fittings, and open the valves. Most homeowners have it mounted and connected in an afternoon.

Ideal Spaces

• Large bedrooms and primary suites
• Home offices and dens
• Finished basements
• Studio apartments and garage conversions

The Easy Pro 12K is sized for rooms up to 550 square feet. If your space has high ceilings, lots of glass, or thin insulation, treat that number conservatively and consider stepping up a size.

Features

• Quiet in the room. The air handler runs between 17.5 and 44.5 dBA, so on its low setting it is quieter than a whisper.
• 19.5 SEER2 inverter efficiency. The variable-speed compressor ramps up and down instead of constantly cycling, which keeps temperatures steady and running costs low.
• Control it from anywhere. Use the included remote, the SmartHVAC app on iOS or Android, or voice commands through Amazon Alexa and Google Assistant.
• Follow Me sensing. The remote doubles as a room sensor, so the system targets the temperature where you actually sit, not just at the wall unit.
• Washable filter. Rinse it, let it dry, and slide it back in. There is nothing to reorder month after month.
• Heats and cools. One unit replaces a window AC and a space heater, with sleep mode, fan-only mode, and auto cool built in.

What you should know

This listing is a complete single-zone system: the outdoor condenser, the indoor wall-mounted air handler, and the pre-charged line set all ship together. Choose the line set length that matches the distance between your indoor and outdoor units, and go a little long rather than a little short.

The unit runs on 115V power but needs its own dedicated circuit with a breaker no larger than 20 amps. If that circuit does not exist yet, budget for an electrician to add one; the rest of the installation is well within reach of a capable homeowner.

Easy Pro is MRCOOL's most affordable DIY line, and part of how it hits that price is a shorter base warranty than the 5th Gen series: 3 years on parts and 5 years on the compressor. If longer coverage matters to you, compare the DIY 5th Gen 12K before you decide.

Warranty

• 5-year compressor warranty
• 3-year parts warranty
