MRCOOL® 5th Gen DIY vs Easy Pro™ 5th Gen — Which Mini-Split Is the Better Choice?

When you’re investing in a ductless mini-split system, you’re not just buying equipment—you’re buying comfort, reliability, energy savings, and warranty protection for the next decade or more.

MRCOOL® gives homeowners two powerful options: the 5th Generation DIY Series and the Easy Pro™ 5th Gen Series.

Both are designed to simplify installation and deliver efficient year-round comfort, but they are built for different types of customers and use cases.

Below is a straight-forward, expert breakdown so you can choose the system that fits your home, budget, and expectations.

1. Installation: DIY Game-Changer vs Semi-DIY Convenience

MRCOOL® 5th Gen DIY — The Only True DIY Mini-Split

The 5th Gen DIY is the industry-leading* self-installation mini-split system.

It uses MRCOOL’s pre-charged QuickConnect® line sets, filled at the factory with R-454B refrigerant.

• No vacuum pumps
• No gauges
• No refrigerant handling
• No HVAC license

Simply connect, tighten, and you’re done.

This technology is why the DIY Series is unmatched in the entire HVAC market.

Comes standard with:

• 25 ft QuickConnect® line set (extendable)
• R-454B refrigerant pre-charged
• Tools-free refrigerant system

This system can be installed in about 3–5 hours with common household tools.

MRCOOL® Easy Pro™ 5th Gen — Easier Than Traditional Systems

The Easy Pro™ uses a 16 ft Fast Connection pre-charged line set, also using R-454B.

Installation is simplified, but not fully DIY.

A licensed technician must connect and finalize the refrigerant circuit to maintain warranty.

This makes Easy Pro ideal for:

• Apartments
• Rental properties
• Light commercial installs
• Homeowners who want professional sign-off

Bottom line:

• DIY 5th Gen = No HVAC professional required
• Easy Pro 5th Gen = Very simplified install, but requires a technician

2. Energy Efficiency: The 5th Gen DIY Wins

Both systems are efficient, but the 5th Gen DIY is the performance champion.

5th Gen DIY 9K BTU

• 23.6 SEER2
• One of the most efficient ductless DIY systems available today
• Lower monthly energy use = lower operating cost for life of the unit

This matters in real dollars:

• More comfort for less energy
• Better humidity control
• Faster heating and cooling
• Higher performance in extreme climates 

Easy Pro 9K BTU

• 20.2 SEER2
• Still excellent vs traditional mini-splits
• Ideal for moderate climates and budget installations 

Efficiency takeaway:

If you want the lowest energy bills, the 5th Gen DIY is the clear winner.

3. Warranty Protection: The Biggest Difference

Here’s where MRCOOL separates casual systems from premium investment-grade HVAC.

MRCOOL® 5th Gen DIY Warranty

• Limited Lifetime Warranty
• 7-Year Compressor
• 5-Year Parts

This is industry-defining coverage—unmatched by any competitor in the DIY space.

It shows MRCOOL’s confidence in the engineering of their flagship product.

MRCOOL® Easy Pro Warranty

• 2-Year Compressor
• 1-Year Parts
• Registration required 

It offers solid protection, but nowhere near the level of the DIY Series.

If long-term reliability matters to you — choose 5th Gen DIY.

4. Smart Features & App Control

Both systems deliver advanced comfort, but the 5th Gen DIY includes more premium features.

5th Gen DIY:

• Voice control (Alexa / Google Assistant)
• Follow Me comfort sensor
• Advanced inverter technology
• Higher cold climate performance
• Better humidity and noise reduction

Easy Pro:

• Quiet operation
• Basic app and smart features
• Excellent temperature stability

If you want technology that feels luxury, the DIY Series is a step above.

5. Line Set Length: Flexibility Matters

Space planning is a real-world problem.

DIY 5th Gen

• Standard 25 ft
• Expandable with extensions
• Perfect for multi-room or attic/basement runs
• Great for coastal or large properties

Easy Pro

• Standard 16 ft
• Fits small rooms, garages, and simple layouts 

Longer lines = more flexibility and fewer compromises.

Which One Should You Choose?

 Choose MRCOOL® 5th Gen DIY if you want:**

• True homeowner installation — no HVAC tech required
• 23.6 SEER2 efficiency or higher
• Lower monthly energy bills
• Stronger long-term reliability
• Lifetime system warranty
• 25 ft line set flexibility
• Premium smart features
• Coastal-grade durability

This is the flagship MRCOOL system.

If you want the best performance and future-proof value, choose DIY 5th Gen.

 Choose MRCOOL® Easy Pro if you want:**

• MRCOOL quality at a lower entry price
• Only require shorter line lengths (16 ft)
• A simpler installation than traditional systems
• Quiet comfort without high-end features
• Solid performance for smaller rooms or secondary spaces
• You plan to use a professional installer

This is the budget-friendly way to get MRCOOL performance.

The Bottom Line

Both the MRCOOL® Easy Pro™ and 5th Gen DIY mini-splits deliver real comfort, inverter technology, and simple installation.

But they are not the same class of product:

• MRCOOL® 5th Gen DIY = Premium performance, best-in-class efficiency, and industry-leading warranties.
• MRCOOL® Easy Pro™ = A more affordable way to upgrade comfort with simplified installation.

If you want maximum efficiency, reliability, smart features, and the strongest warranty in HVAC, the 5th Gen DIY stands alone.

If you need solid performance at a lower cost, and you don’t mind a technician finishing the install, the Easy Pro is the perfect fit.
