How to Choose the Right MRCOOL® Mini-Split for Your Home
Choosing the right HVAC system doesn’t have to feel complicated. With MRCOOL® DIY mini-splits, homeowners now have flexible options for every room size, layout, and budget. The key is knowing which system is right for your home.
At Cool Heat Direct, we’ve made it simple. Here’s what you need to consider before you buy.
1. Match Your Room Size to the Right BTU
Think of BTUs as the “horsepower” of your system. Too small, and your unit will struggle. Too large, and you’ll waste energy.
General BTU Guide:
-
Up to 350 sq. ft. → 9,000 BTU (perfect for bedrooms, offices, small apartments)
-
350–600 sq. ft. → 12,000 BTU (living rooms, kitchens, medium-sized spaces)
-
600–1,000 sq. ft. → 18,000 BTU (large open-plan areas, basements)
-
1,000–1,500 sq. ft. → 24,000 BTU (lofts, large family rooms)
-
Multi-room setups → Multi-zone systems (connect multiple air handlers to one condenser)

2. Decide: Single-Zone or Multi-Zone?
-
Single-Zone: Perfect if you’re cooling or heating one room (like a garage, office, or bedroom).
-
Multi-Zone: One outdoor unit powers up to 5 indoor air handlers. Great for families, larger homes, or mixed-use spaces.
MRCOOL’s DIY Multi-Zone is one of the most flexible systems on the market — and you can expand as your needs grow.
3. Compare MRCOOL Series Options
MRCOOL offers a solution for every type of homeowner:
-
DIY® Series (4th & 5th Gen) → Most popular, easy to install, covers single or multi-zone needs.
-
Easy Pro® Series → Best for smaller spaces, super affordable.
-
Universal® Series → Replaces traditional central systems; ducted or ductless flexibility.
-
Ceiling Cassette Systems → Sleek, hidden look for modern interiors.
Each one is backed by MRCOOL’s trusted warranty and Cool Heat Direct’s customer support.
4. Think About Future Needs
Planning to finish a basement? Add a garden office? Rent out a loft?
