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.
