MRCOOL EasyPro 9K Mini Split System – 5th Generation – 115V

The MRCOOL EasyPro 9K 115V Mini Split System is a complete 5th Generation single-zone ductless heat pump designed to provide efficient heating and cooling with simplified DIY-friendly installation. It combines the EZPRO-09-HP-C-11516D-O outdoor condenser with the EZPRO-09-HP-WMAH-115D-O wall-mounted indoor air handler and a 16-foot pre-charged line set.

This 115V matched system delivers 9,000 BTU of nominal cooling capacity and 10,000 BTU of heating capacity. MRCOOL identifies the system for appropriately sized residential spaces of up to approximately 400 square feet under ideal conditions. Actual coverage depends on climate, insulation, windows, ceiling height, construction, occupancy, and other load factors. Complete a proper load calculation before selecting equipment.

MRCOOL EasyPro 9K 115V Mini Split System Overview

The MRCOOL EasyPro 9K 115V Mini Split System uses DC inverter technology to adjust compressor output according to current heating or cooling demand. Variable operation helps maintain a more consistent indoor temperature while reducing the repeated full-power cycling associated with conventional fixed-speed equipment.

The system achieves an efficient rating of 20.2 SEER2 and 9.2 HSPF2 for reliable year-round performance. Its documented performance ratings apply specifically to the listed 9K 115V indoor and outdoor EasyPro component combination.

MRCOOL EasyPro 9K 115V System Compatibility

The MRCOOL EasyPro 9K Mini Split System (115V) must use the listed 115V EasyPro indoor and outdoor components. Equipment from different capacities, voltages, generations, refrigerant platforms, or MRCOOL product lines should not be substituted unless current manufacturer documentation explicitly confirms compatibility.

This 115V ductless system can be considered for bedrooms, home offices, nurseries, small additions, studios, and other appropriately sized spaces. A professional load calculation is the most reliable way to determine whether a 9,000 BTU system is suitable for a particular application.

Smart Comfort Controls

The MRCOOL EasyPro 9K 115V Mini Split System includes smart-control capability through the MRCOOL SmartHVAC application for compatible Apple and Android devices. Available functions can include temperature adjustment, operating-mode selection, schedules, fan settings, and remote system control.

Supported Amazon Alexa and Google Assistant integrations provide compatible voice-control options. The Follow Me® function uses temperature information near the remote-control location to help manage comfort around the occupant instead of relying exclusively on the sensor inside the wall-mounted air handler.

R-454B Refrigerant & Pre-Charged Line Set Information

The MRCOOL EasyPro 9K 115V Mini Split System uses R-454B refrigerant and includes a 16-foot pre-charged Easy Connection line set designed to simplify installation without requiring a certified technician to evacuate refrigerant lines. Installation and service must follow MRCOOL instructions and all applicable safety requirements for R-454B equipment.

Confirm that the 16-foot line-set length is appropriate for the planned indoor and outdoor equipment locations before installation. Line sets should not be cut or modified.

Warranty and Official Documentation

The MRCOOL EasyPro 9K 115V Mini Split System comes with a standard limited warranty providing manufacturer coverage from the documented purchase date. Coverage remains subject to MRCOOL’s current terms, exclusions, installation requirements, and claim procedures. Labor, shipping, refrigerant, maintenance, and other costs may not be included.

Review the MRCOOL EasyPro 5th Generation product brochure, the MRCOOL installation manual, and the MRCOOL limited warranty before installing or operating the equipment.

Installation Notice

While the MRCOOL EasyPro 9K 115V Mini Split System simplifies the refrigerant line connection with its pre-charged design, installation must still comply with electrical, structural, drainage, clearance, and local code requirements.

The outdoor condenser requires a properly sized 115V dedicated electrical circuit. Electrical work should be completed or reviewed by a qualified professional when required. Installation must comply with current MRCOOL instructions, the National Electrical Code, applicable building codes, and local permit requirements.
