MRCOOL EASY PRO® GUIDE
Compare MRCOOL Easy Pro® DIY mini split systems by BTU size, energy efficiency, installation requirements, smart features, and heating & cooling performance. Designed for homeowners who want energy-efficient comfort without expensive professional installation, Easy Pro® systems combine true DIY installation with inverter-driven performance, quiet operation, and built-in smart controls.
The MRCOOL Easy Pro® DIY Mini Split Series was built for homeowners who want reliable heating and cooling without the cost and complexity of traditional HVAC installation. Whether you're upgrading a garage, workshop, bedroom, office, addition, basement, cabin, or open-concept living area, Easy Pro® systems provide energy-efficient comfort with simplified installation designed specifically for DIY users.
Unlike conventional ducted HVAC systems that require vacuum pumps, refrigerant charging, and licensed installation, Easy Pro® systems use factory-sealed Quick Connect® line sets pre-charged with R-454B refrigerant. This streamlined installation process eliminates the need for specialized HVAC tools while making installation significantly faster and more approachable for homeowners.
The Easy Pro® lineup includes multiple BTU sizes to support a wide range of room sizes and applications:
All Easy Pro® systems use advanced DC inverter compressor technology for improved energy efficiency, quieter operation, better indoor temperature consistency, and lower operating costs compared to conventional heating and cooling equipment.
Additional features include built-in Wi-Fi connectivity, smartphone app control, compatibility with Amazon Alexa and Google Assistant, washable filters, Gold Fin® condenser protection, upgraded warranty coverage, and simplified DIY installation using Quick Connect® technology.
The latest Easy Pro® systems also feature updated warranty coverage with a 5-year compressor warranty and 3-year parts warranty, along with new 11.5 ft pre-charged Quick Connect® line sets designed to simplify installation while maintaining the same trusted heating and cooling performance.
The latest MRCOOL Easy Pro® systems include an updated 11.5 ft pre-charged Quick Connect® line set and revised warranty coverage compared to earlier Easy Pro® models that included a 16 ft installation kit.

Choosing the correct MRCOOL Easy Pro® mini split size depends on your room size, insulation quality, ceiling height, sunlight exposure, and overall layout. In general:
Proper sizing is important for both comfort and efficiency. Oversized systems may short cycle, while undersized systems can struggle to maintain temperature during extreme weather conditions.
Yes. MRCOOL Easy Pro® systems are specifically designed for true DIY installation. Each system includes a pre-charged Quick Connect® line set factory-sealed with R-454B refrigerant, eliminating the need for vacuum pumps, manifold gauges, refrigerant charging, or specialized HVAC tools.
Most homeowners with basic tools and moderate DIY experience can complete installation themselves by following the included instructions. Electrical connections should always comply with local building and electrical codes.
No. MRCOOL Easy Pro® systems are ductless mini split heat pump systems, meaning they do not require traditional HVAC ductwork for installation or operation.
Instead of using large air ducts throughout the home, Easy Pro® systems connect a compact indoor air handler directly to an outdoor condenser using a small refrigerant line set. This allows for faster installation, improved energy efficiency, zoned comfort control, and greater flexibility compared to traditional central HVAC systems.
Yes. MRCOOL Easy Pro® systems are ductless heat pump systems that provide both air conditioning and heating from a single system. In cooling mode, the system removes heat from inside your home, while heating mode reverses the process to bring warmth indoors during colder temperatures.
Easy Pro® systems are designed to operate in outdoor temperatures ranging from approximately -13°F to 122°F for dependable year-round comfort.
MRCOOL Easy Pro® systems use advanced DC inverter technology to deliver high-efficiency heating and cooling while reducing energy consumption compared to conventional HVAC systems. Depending on the model size, Easy Pro® systems offer efficiency ratings up to 20.2 SEER2 and up to 9.3 HSPF2-4.
Inverter-driven compressor technology continuously adjusts output based on actual demand instead of repeatedly cycling on and off, helping improve indoor comfort while lowering operating costs.
Yes. MRCOOL Easy Pro® systems include built-in Wi-Fi connectivity and are compatible with the MRCOOL® Smart HVAC Controller® app, allowing you to adjust temperature settings, operating modes, fan speeds, and schedules directly from your smartphone.
Easy Pro® systems are also compatible with Amazon Alexa and Google Assistant for hands-free smart home control.
MRCOOL® Follow Me® technology uses a temperature sensor built into the handheld remote control to monitor the temperature where you are located instead of only measuring temperature near the indoor air handler.
This helps the system maintain more accurate comfort levels in occupied areas of the room while improving overall temperature consistency.
MRCOOL Easy Pro® ductless mini split systems are designed for quiet indoor operation, with certain models operating as low as 17.5 dB(A) in Sleep mode. This makes Easy Pro® systems ideal for bedrooms, offices, studios, living spaces, and other noise-sensitive environments.
Outdoor condensers are also engineered for low operating noise while maintaining efficient heating and cooling performance.
Yes. The latest MRCOOL Easy Pro® systems use R-454B refrigerant, a next-generation refrigerant designed to provide lower environmental impact compared to older refrigerant technologies.
R-454B systems maintain strong heating and cooling performance while helping meet evolving environmental regulations and efficiency standards.
Depending on your location, utility provider, and local energy-efficiency programs, certain MRCOOL Easy Pro® systems may qualify for rebates, tax credits, or energy-efficiency incentives.
Qualification requirements vary by region and program. We recommend checking with your local utility company or reviewing current federal, state, and local incentive programs for the most accurate information.
Unlike traditional central HVAC systems that require ductwork, professional refrigerant charging, and complex installation, MRCOOL Easy Pro® systems are designed for simplified DIY installation using pre-charged Quick Connect® line sets.
