Tucson casitas are popular for guests, rentals, and home offices. Mini-splits are the ideal climate control solution, and here is everything you need to know.
Why Mini-Splits for Casitas?
No Ductwork Needed
Casitas often do not have ductwork extensions from the main house. Mini-splits mount on walls and connect to an outdoor unit via a small refrigerant line -- no major construction required.
Independent Temperature Control
Guests can set their own comfort level without affecting the main house system.
Energy Efficiency
Only cool or heat the casita when it is occupied. No wasting energy on empty rooms.
“Mini-splits are significantly quieter than window units, more efficient, and they heat and cool. One install handles both seasons.”
