Can I really install this myself?

Yes, if you are comfortable with basic electrical and mounting work. The line set comes pre-charged with quick-connect fittings, so no vacuum pump or brazing is needed. Many owners hire help only to lift the outdoor unit.

What size room does 36,000 BTU cover?

MRCOOL rates it for up to about 550 square feet. That suits a large open room, garage or workshop. In a small, well-insulated bedroom it will short-cycle and cool unevenly.

Does it heat as well as it cools?

It is a heat pump, so it provides both. Owners report solid heating in mild to moderate cold. In sustained freezing weather, output drops and a backup heat source may be needed.

Does it work with Alexa and Google Assistant?

Yes. It connects over Wi-Fi and works with both, and the MRCOOL app adds scheduling, timers and sleep mode.

What comes in the box?

The indoor and outdoor units, a pre-charged line set, remote control, mounting hardware and installation manual. Line-set length depends on the kit you choose, so check it before planning placement.

How does it compare with a pro-installed brand?

Mitsubishi and Fujitsu units are typically quieter and more efficient, but require a licensed installer. The MRCOOL trades some of that refinement for self-installation and easier serviceability.
