The MRCOOL DIY Easy Pro 18K 18,000 BTU 20 SEER2 Ductless Mini Split Air Conditioner and Heat Pump is a 230V single-zone system rated for spaces up to 800 square feet, delivering 17,000 BTU of cooling and 18,000 BTU of heating from a single wall-mounted unit. A compact outdoor condenser and an efficient inverter compressor keep it running smoothly through both seasons.
Installation is where the DIY line earns its name. The pre-charged Quick Connect line set means no vacuum pump, no gauges, and no special tools or refrigerant certification. Mount the bracket, hang the air handler, set the condenser outside, join the fittings, and open the service valves. Most homeowners have it mounted and connected in an afternoon.
Ideal Spaces
- Primary suites and large bedrooms
- Garages and workshops
- Open living and dining areas
- Finished basements
Figure on 800 square feet as the ceiling in a reasonably insulated space. A garage with an uninsulated door or a room full of west-facing glass behaves like a bigger room, so when in doubt, size up.
Features
- 20 SEER2 inverter performance. The compressor modulates to match the load instead of slamming on and off, holding your set temperature with less energy.
- Whisper-level operation. The air handler ranges from 18.5 to 46.5 dBA, so at night it fades into the background.
- App and voice control. Run it from the SmartHVAC app on iOS or Android, ask Amazon Alexa or Google Assistant, or use the included remote.
- Follow Me temperature control. The remote reads the temperature where you are and tells the system to condition around you.
- Washable filter with anti-mildew function. The filter rinses clean, and the anti-mildew cycle dries the coil after cooling to keep odors out.
- Oscillating airflow. Motorized louvers sweep air across the room instead of blasting one spot.

What you should know
Everything needed for a single zone ships together: the condenser, the wall-mounted air handler, and the pre-charged line set. Measure the run between where the indoor and outdoor units will sit, then pick the 11.5, 16, 25, or 50 ft option to match.
This is a 208/230V unit, not plug-in power. It needs a dedicated circuit with a breaker no larger than 20 amps, so if that circuit does not exist yet, have an electrician run one before install day. The rest of the job is standard DIY territory.
One naming note: the 18K figure refers to heating capacity, and rated cooling is 17,000 BTU. As with the rest of the Easy Pro line, the base warranty is 3 years on parts and 5 years on the compressor, which is shorter than MRCOOL's 5th Gen series. That trade-off is a big part of the lower price.
Warranty
- 5-year compressor warranty
- 3-year parts warranty
