MRCOOL Easy Pro vs. DIY 4th Generation | 5 Differences

by Pete Lader January 24, 2023

What are the differences between the MRCOOL Easy Pro Series and MRCOOL DIY 4th Generation Series?

Both are the main ductless mini split series from MRCOOL.

The Easy Pro Series is an entry-level line of single-zone mini splits, while the DIY 4th Generation Series is MRCOOL's main Mini Split line, offering single and multi-zone units that can cool and heat one to five rooms/zones.

When comparing the two series, we'll focus on their single-zone units since the Easy Pro only offers single zone units.

5 Key differences

1. Variety of BTUs:

2. Condenser Efficiency:

  • DIY 4th Generation systems generally have higher performance ratings (SEER) compared to Easy Pro systems, making them more energy efficient.
  • We can see this by comparing the SEER ratings:

    Single Zone BTU 4th Generation SEER / SEER 2 Rating Easy Pro SEER / SEER 2 Rating
    9K 20 / 20
    12K 22 / 22.5 18 / 18.9
    18K 22 / 22.7 18.3 / 19.3
    24K 20.5 / 20.5 18 / 18
    36K 18 / 18.3

3. Condenser Operating Temperature:

  • DIY 4th Generation series can operate in more extreme temperatures compared to Easy Pro series, providing better performance in harsh climates.
  • Let's compare the Operating Temperature:

    Single Zone BTU

    4th Generation Operating Temperature

    9K Cool Mode: 5°F - 122°F
    Heat Mode: 5°F - 75.2°F
    12K Cool Mode: -13°F - 122°F
    Heat Mode: -13°F - 75°F
    Cool Mode: 5°F - 122°F

    Heat Mode: -13°F - 75°F
    Cool Mode: 5°F - 122°F
    Heat Mode: 5°F - 75.2°F
    36K Cool Mode: 5°F - 122°F
    Heat Mode: 5°F - 75°F
4. Lineset Included:
  • Easy Pro comes with a 16' lineset, while DIY 4th Generation includes a 25' lineset. Additional lineset purchase is required if longer length is needed.
5. Manufacturer's Warranty:
  • DIY 4th Generation offers a 5-year parts and 7-year compressor warranty, whereas Easy Pro provides a 2-year parts and 1-year compressor warranty.

    Which one should you buy?

    In summary, if you prioritize energy efficiency, wider operating temperatures, and a more comprehensive warranty, the DIY 4th Generation Series is the better choice despite being more expensive. However, if these factors are not top priorities for you, the Easy Pro Series is still a great option. Both series qualify for tax and energy rebates and can be installed by yourself.

    • I have a room with 17’ celing, 450 sq ft. To run the lines to an outside wall I would need between 30’ and 50’ of line. If I use direct route through the attic I would need 25’. That would eliminate most of the white line hiding the lines across the front of my gray house.
      So my question is can the air handler unit be installed on an inside wall?
