Room-by-room control without ductwork—perfect for additions or offices.
Garden Grove's ADU wave runs on mini-splits — efficient, independent, and correctly sized per unit rather than stealing capacity from the main home.
Inland heat plus original 1950s-era ductwork is a common combination we find driving both high bills and uneven room-to-room comfort here.
