Frequently Asked Questions

What's the difference between the 5th Gen and 4th Gen?

The 5th Gen MRCOOL DIY® Mini Split offers several key upgrades over the 4th Gen, focusing on efficiency, advanced technology, and eco-friendliness.

Here’s what’s new with the 5th Gen:

  • Next-Gen R-454B Refrigerant: A more environmentally friendly refrigerant with lower global warming potential (GWP), compliant with the latest HVAC regulations.
  • Higher Energy Efficiency: Improved SEER2 ratings for greater energy savings and optimized performance.
  • Enhanced System Reliability: Upgraded components for better heating and cooling performance.

For a full breakdown, check out our blog.

Is this system DIY-friendly?

Yes! The MRCOOL 5th Gen is designed with pre-charged line sets, making it one of the only multi-zone systems on the market suitable for DIY installation without needing a certified HVAC technician (for most installations).

How do I know what BTU size I need for my rooms?

A general rule of thumb is 20 BTU per square foot of space. Here's a rough guide:

  • 9,000 BTU = 180 - 350 sq ft
  • 12,000 BTU = 351- 500 sq ft
  • 18,000 BTU = 501 – 750 sq ft
  • 24,000 BTU = 751 – 1,000 sq ft
  • 36,000 BTU = 1,001 - 1,500 sq ft

Consider factors like ceiling height, insulation, sunlight exposure, and number of occupants.

Does the 5th Gen qualify for tax credits?

To check if your MRCOOL 5th Gen Single Zone Mini Split qualifies for tax credits, follow these steps:

  1. Verify the Model - Ensure your unit is one of the eligible models: 9K, 12K, 18K, or 24K BTU. The 36K BTU model does not qualify.
  2. Check the AHRI Certificate - Go to the AHRI (Air-Conditioning, Heating, and Refrigeration Institute) Directory and search for your unit’s AHRI number to confirm its eligibility.
  3. Review IRS Guidelines - The IRS requires energy-efficient equipment to meet specific SEER2 (Seasonal Energy Efficiency Ratio) and HSPF2 (Heating Seasonal Performance Factor) standards. Check the latest Energy Star guidelines.
  4. Consult a Tax Professional - To ensure you can claim the credit, consult a tax advisor and review IRS Form 5695 for residential energy credits.
  5. Save Your Purchase Receipt - Keep your proof of purchase and any related documentation to submit with your tax filing.

What if I need a different line set length?

This system comes with a standard 25 ft pre-charged line set. If you need a shorter or longer line set, you will need to purchase a different one separately. Please note that the included 25 ft line set cannot be returned or exchanged, even if unused.

Available line set lengths: 16 ft, 25 ft, 35 ft, and 50 ft

Be sure to choose the correct size and line set type for your indoor unit:

Always verify compatibility with your specific model before ordering an alternative line set.

What is the warranty?

The MRCOOL 5th Generation DIY Mini-Split systems offer the following warranty coverage:

  • Limited Lifetime Compressor Warranty: This warranty provides coverage for the compressor for the lifetime of the unit for the original registered owner. To qualify, the unit must be registered within 60 days of installation, and the owner must enroll in the MRCOOL Care Program within 4 months of installation.
  • 7-Year Compressor Replacement Warranty: This warranty ensures that if the compressor fails within the first seven years, MRCOOL will provide a replacement.
  • 5-Year Parts Warranty: This warranty covers all parts of the system for five years from the date of purchase.

    To activate these warranties, it's essential to register your product promptly after installation. This ensures you receive the full benefits of the warranty coverage.

    Additionally, regular maintenance is crucial to keep your warranty valid. Enrolling in the MRCOOL® Protection Program can help maintain your system's longevity by providing DIY cleaning kits and filters biannually.
