A quick buying guide

What should you look at before choosing?

These MRCOOL DIY Select systems pair a black indoor unit with a 9,000 or 12,000 BTU outdoor unit. The standard package includes an 11.5 ft pre-charged connection set. Both sizes are currently shown for preorder planning, but ordering is not open yet. You can still compare the complete package, measure your route, and review the electrical and installation details while you wait.

Choose the size

What does the space actually need?

Square footage is a useful clue, but it misses your windows, insulation, air leaks, climate, and ceiling height. A heating and cooling load calculation considers those details and helps you choose the right size.

Make sure the power works

Can your power source support this system?

The 115V label is only a starting point. Make sure your circuit and full power setup can handle the system, including the inverter, batteries, generator, solar charging, and other loads.
