Model: EZPRO-09-HP-11516D-O — The all-in-one DIY-friendly 5th Generation MRCOOL Easy Pro 9 K BTU Mini-Split System delivers efficient, quiet heating and cooling for spaces up to 400 sq ft. Perfect for bedrooms, home offices, or specialized zones such as server rooms or studios.

This complete single-zone system pairs a sleek, Wi-Fi-enabled indoor air handler with a durable outdoor condenser and includes a 16 ft pre-charged Fast Connection Line Set and DIYPRO Cable for true plug-and-play installation. Designed for energy-efficient performance and simple setup, the Easy Pro Series combines premium comfort with smart-home convenience.

Looking for a 6K or 6000 BTU Mini Split?

MRCOOL does not manufacture a 6,000 BTU single-zone Easy Pro system. However, this 9K BTU inverter-driven model is designed to automatically adjust output based on room demand, making it an ideal modern replacement for traditional 6K systems.

Unlike fixed-capacity mini splits, the Easy Pro 9K can modulate down during lower load conditions. This means if you are searching for:

  • 6k mini split
  • 6000 BTU mini split system
  • 6k 115V mini split
  • small room single zone mini split

This 9K inverter system is typically the correct solution for bedrooms, offices, studios, and other small spaces that would previously have used a 6K unit.

Key Features & Benefits

  • Streamlined DIY Setup: 16 ft pre-charged Fast Connection Line Set and DIYPRO Cable allow homeowners to install without vacuum pumps or professional HVAC service.
  • Smart Home Compatibility: Built-in Wi-Fi supports the MRCOOL Smart HVAC Controller App and integrates with Amazon Alexa and Google Assistant for voice control.
  • Adaptive Comfort Features: Handheld remote with Follow Me sensor maintains your preferred temperature where you are in the room.

  • Low Ambient Cooling: Performs efficiently even when outdoor temperatures drop to 5 °F — great for IT spaces, garages, or greenhouses.
  • Built for Durability: Gold Fin-coated condenser resists corrosion and extends service life in coastal or humid climates.
  • Enhanced Indoor Air Quality: Active Clean Technology maintains a cleaner coil, helping to reduce maintenance and keep indoor air fresh.
  • Eco-Friendly & Certified: Uses R-454B refrigerant; meets AHRI, NEEP ccASHP, and CEE Tier 1 (North) standards.

Does this system require professional installation?

Answer:

No. MRCOOL Easy Pro™ systems are designed for true DIY installation. They use factory-sealed MRCOOL® DIY® Quick Connect Pre-Charged Line Sets, allowing homeowners to install the system without vacuum pumps, refrigerant handling, or specialized HVAC tools.

Does the Easy Pro system include a pre-charged line set?

Answer:

Yes. Easy Pro systems include a 16 ft MRCOOL® DIY® Quick Connect Pre-Charged Line Set, which comes factory-charged and ready to connect. No on-site charging or evacuation is required.

What size room is the Easy Pro designed to heat and cool?

Answer:

Coverage depends on system size. Easy Pro units are commonly used for spaces such as bedrooms, garages, home offices, workshops, additions, and bonus rooms. Always size based on square footage, insulation, ceiling height, and climate conditions.

How does the Easy Pro perform in cold weather heating?

Answer:

The MRCOOL Easy Pro™ is designed for reliable heating in mild to moderate winter conditions. Heating efficiency begins to decrease as outdoor temperatures approach 5°F, which is typical for standard inverter heat pump systems. In colder climates or regions with frequent sub-freezing temperatures, supplemental heat or a cold-climate system may be recommended.

What is the difference between Easy Pro and E-Star heating performance?

Answer:

The MRCOOL Easy Pro™ and MRCOOL E-Star® are designed for different climate needs.

Easy Pro systems are optimized for cost-effective, DIY heating and cooling in moderate climates, with heating performance tapering near 5°F.

MRCOOL E-Star® systems are cold-climate rated and maintain strong heating performance down to approximately -13°F, making them better suited for colder regions or primary winter heating.

Is the Easy Pro recommended as a primary heat source in cold climates?

Answer:

In colder climates where temperatures regularly fall below 5°F, the Easy Pro™ is best used as a supplemental or secondary heat source. For primary heating in cold regions, MRCOOL E-Star® or Hyper-Heat style systems are recommended.

Why does MRCOOL DIY Direct explain heating performance differences between systems?

Answer:

At MRCOOL DIY Direct, we believe in transparency, not just making a sale. All MRCOOL systems deliver excellent, energy-efficient cooling. The primary difference between models comes down to heating performance in cold weather, which is driven by compressor design and system classification.

Like all heat pump brands, MRCOOL offers different tiers: standard heating systems for moderate climates, enhanced cold-weather systems, and advanced hyper-heating models for extreme temperatures. Our goal is to help you choose the right system for your climate, usage, and expectations so you’re satisfied long after installation.

MRCOOL EASY PRO® GUIDE

MRCOOL Easy Pro® 5th Gen DIY Mini Split Guide

Compare BTU sizes, energy efficiency, installation features, smart controls, and heating & cooling performance to choose the best MRCOOL Easy Pro® 5th Generation ductless mini split system for your home, garage, office, workshop, or addition.

Easy Pro® DIY Mini Split Overview

The MRCOOL Easy Pro® 5th Generation DIY Mini Split Series was designed for homeowners who want affordable, energy-efficient heating and cooling without the complexity of a traditional HVAC installation. Whether you're upgrading a garage, workshop, bedroom, addition, office, cabin, or small home, the Easy Pro series offers a streamlined ductless solution with modern smart features, high-efficiency inverter technology, and true do-it-yourself installation options.


Unlike traditional central HVAC systems that require expensive ductwork and professional labor, MRCOOL Easy Pro systems use compact wall-mounted air handlers paired with outdoor condensers to deliver targeted comfort exactly where you need it. Each system includes a 16-foot installation kit, making setup faster and more approachable for homeowners looking to save on installation costs.

The 5th Gen Easy Pro lineup includes multiple BTU sizes to fit a wide range of room sizes:

  • 9,000 BTU systems for spaces up to approximately 400 sq ft
  • 12,000 BTU systems for areas up to 550 sq ft
  • 18,000 BTU systems for rooms up to 800 sq ft
  • 24,000 BTU systems for spaces up to 1,050 sq ft

All Easy Pro systems use advanced DC inverter technology for better temperature consistency, improved efficiency, quieter operation, and lower energy consumption compared to conventional HVAC equipment.

MRCOOL Easy Pro® Frequently Asked Questions

What size MRCOOL Easy Pro® system do I need?

Choosing the correct BTU size depends on your room size, insulation quality, ceiling height, sun exposure, and climate. As a general guideline:

  • 9k BTU: Up to 400 sq ft
  • 12k BTU: Up to 550 sq ft
  • 18k BTU: Up to 800 sq ft
  • 24k BTU: Up to 1,050 sq ft

Oversizing or undersizing a mini split can reduce efficiency and comfort, so proper sizing is important before ordering.

Is the MRCOOL Easy Pro® really DIY friendly?

Yes. The Easy Pro series is specifically designed to simplify installation compared to traditional mini split systems. Each system includes a 16-foot installation kit, and many homeowners install these systems themselves using standard tools and careful planning.


However, electrical connections and local code requirements may still require a licensed electrician depending on your area.

Does the Easy Pro® series provide both heating and cooling?

Yes. Every MRCOOL Easy Pro® system is a heat pump, meaning it provides both air conditioning and heating from a single system. This makes it ideal for year-round comfort in bedrooms, garages, workshops, additions, offices, cabins, and other spaces.

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

The Easy Pro® 5th Gen systems offer high-efficiency performance with SEER2 ratings up to 20.2 depending on the model selected.


DC inverter technology continuously adjusts compressor speed instead of constantly turning on and off, helping reduce power usage while maintaining more stable temperatures.

Can I control the system from my phone?

Yes. The Easy Pro® series includes WiFi capability and smartphone app control, allowing you to:

  • Adjust temperature remotely
  • Change operating modes
  • Set schedules and timers
  • Monitor system performance

The systems are also compatible with Amazon Alexa and Google Assistant for voice control functionality.

What is Follow Me® technology?

Follow Me® technology uses a temperature sensor inside the remote control to help the system adjust comfort based on where you are in the room instead of only sensing temperature at the indoor unit itself.

This can improve comfort consistency in larger or unevenly conditioned spaces.

How quiet is the MRCOOL Easy Pro® system?

The Easy Pro® indoor air handlers are designed for quiet operation, with sound levels as low as 17.5-18 dB(A) on certain low-speed settings depending on the model.

That makes them ideal for:

  • Bedrooms
  • Nurseries
  • Offices
  • Media rooms
  • Home gyms

Because apparently humans enjoy sleeping without a compressor sounding like a cargo helicopter beside the bed. Strange preference, but understandable.

What refrigerant does the 5th Gen Easy Pro® use?

The MRCOOL Easy Pro® 5th Gen series uses R-454B refrigerant.


R-454B is a newer-generation refrigerant designed to improve environmental performance compared to older refrigerants while maintaining strong cooling and heating efficiency.

Does the Easy Pro® qualify for rebates or energy incentives?

Many Easy Pro® systems qualify for regional efficiency programs and rebate opportunities, including NEEP and CEE Tier 1 eligibility depending on the model.


Available rebates vary by state, utility provider, and installation requirements.

What makes the Easy Pro® different from traditional central HVAC systems?

Unlike central HVAC systems that rely on ductwork, ductless mini splits deliver conditioned air directly into the room. This can help reduce energy loss associated with ducts while allowing more targeted comfort control.

The Easy Pro® series is especially popular for:

  • Older homes without ductwork
  • Garages and workshops
  • Room additions
  • Converted attics
  • Tiny homes
  • Home offices
  • Supplemental heating and cooling

It also offers a simpler installation process and lower upfront installation costs compared to many traditional HVAC systems.
