Ductless Mini-Split Systems for Sonoma County Homes
Mini-split heat pumps are the ideal solution for homes without ductwork, room additions, garage conversions, ADUs, and rooms that are always too hot or too cold. They deliver targeted heating and cooling with exceptional energy efficiency — and the current federal Inflation Reduction Act provides a 30% tax credit (up to $2,000) on qualifying installations.
Best Uses for Mini-Splits
- Homes without ductwork (older construction)
- Room additions that aren’t connected to the central system
- Garage conversions and ADUs (accessory dwelling units)
- Rooms that are always uncomfortable (too hot or too cold)
- Home offices that need independent temperature control
- Sunrooms and bonus rooms
Multi-Zone Systems
A single outdoor compressor can connect to 2–4 indoor units in different rooms, each with its own thermostat. This lets family members control their own room temperature without affecting the whole house.
