Frequently Asked Questions

In larger master bedrooms (especially those toward the upper end of the 400–600 sq ft range), a 12 000 BTU mini split can be an excellent choice. For very large or unusually high-ceilinged master suites, consult a sizing pro to verify capacity versus load.

Installation costs vary widely based on labor rates, wall penetrations, electrical work, and additional accessories. On average, professional installation of a 12 000 BTU system ranges around $2 500 – $5 000, though DIY kits and simpler installs can be less.
