Mini-splits are far more efficient, quieter, and better looking than window units. They provide a permanent installation with full climate control including both heating and cooling. Unlike window units, mini-splits don't block your window, don't create security vulnerabilities, and operate at a fraction of the noise level.
It depends on your home layout. Most homes need 2-4 zones. Bedrooms, living room, and home office are the most common areas to zone. We'll assess your home and recommend the right configuration during your free estimate.
