Home Theater Mini-Split Installation
West Chester, PA
A West Chester homeowner needed a dedicated comfort solution for his in-home movie theater.
We installed a Fujitsu AIRSTAGE mini-split system with a ceiling-mounted indoor cassette, providing heating and cooling without taking up valuable wall space.

Ceiling-Mounted Comfort
This installation uses a ceiling cassette instead of a traditional wall-mounted mini-split head, helping preserve the theater's wall space and finished appearance.
Mini-split systems can be a great solution for home theaters, additions, home offices, garages, bonus rooms, and other spaces needing independent temperature control.
