Mini-Split: Just a Small Hole
A mini-split links the indoor head to the outdoor unit through a 3-inch hole in an outer wall. No duct runs. No harm to old plaster or wood trim.

Heat and Cool Your Historic Home Without Ruining It
East Sacramento, Land Park, and Curtis Park homes have plaster walls and old wood trim. Historic rules protect these features. A full ducted HVAC setup would cut through those walls. A mini-split does not. It needs only a small hole through an outer wall.
Historic Permit Rules
Sacramento historic zones have rules on what can be seen from the street. We place units to meet those rules. We work with boards when a review is needed.
Small-Duct Option
Homes that want central air can use a small-duct high-speed system. It runs 2-inch flex tubes through wall cavities. Very little demo work is needed.

Permits and Preservation Board Coordination
California's 2025 energy rules now in force in 2026 apply to all HVAC setups. A permit is needed for any new mini-split. In a historic overlay zone, the outdoor unit placement may also need board review. Fresh Air knows the Sacramento permit path and files the paperwork for you.
We have set up over 900 units in Sacramento since 2009, CSLB #945361. A single-zone mini-split for a bungalow starts at $3,000 to $5,000. A multi-zone setup runs $5,000 to $10,000. A free estimate comes first. Call (916) 416-8181.
