MRCOOL EASY PRO® GUIDE

MRCOOL Easy Pro® DIY Mini Split Systems

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.

MRCOOL Easy Pro® 5th Gen DIY Mini Split Guide


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:

  • 9K BTU systems for spaces up to approximately 400 sq ft
  • 12K BTU systems for rooms up to approximately 550 sq ft
  • 18K BTU systems for areas up to approximately 800 sq ft
  • 24K BTU systems for spaces up to approximately 1,050 sq ft


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.

MRCOOL Easy Pro® Frequently Asked Questions

What is the difference between the original Easy Pro® and the new 11.5 ft version?

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.


The newer Easy Pro® versions now include a 5-year compressor warranty and 3-year parts warranty while maintaining the same core heating and cooling performance, inverter technology, smart features, and DIY installation design homeowners expect from the Easy Pro® lineup.

What size MRCOOL Easy Pro® system do I need?

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:

  • 9K BTU systems work well for rooms up to approximately 400 sq ft
  • 12K BTU systems are ideal for spaces up to approximately 550 sq ft
  • 18K BTU systems can heat and cool areas up to approximately 800 sq ft
  • 24K BTU systems are designed for larger spaces up to approximately 1,050 sq ft


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.

Can I really install an MRCOOL Easy Pro® system myself?

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.

Do MRCOOL Easy Pro® systems require ductwork?

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.

Do MRCOOL Easy Pro® systems provide both heating and cooling?

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.

How energy efficient is the MRCOOL Easy Pro® 5th Gen series?

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.

Can I control my MRCOOL Easy Pro® system from my phone?

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.

What is MRCOOL® Follow Me® technology?

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.

How quiet are MRCOOL Easy Pro® mini split systems?

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.

Do MRCOOL Easy Pro® systems use R-454B refrigerant?

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.

Do MRCOOL Easy Pro® systems qualify for rebates or energy incentives?

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.

What makes MRCOOL Easy Pro® different from traditional HVAC systems?

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.


Easy Pro® ductless systems also provide zoned heating and cooling, improved energy efficiency, quieter operation, and flexible installation options without the cost and space requirements associated with traditional ducted HVAC systems.
