Ductless Mini-Splits · Santa Rosa, CA
Ductless Mini-Splits in Santa Rosa, CA
Many older Sonoma County homes, cottages and accessory units were built with wall heaters or no central system at all. A ductless mini-split adds efficient heating and cooling without cutting in new ducts.
Request an HVAC technicianHow it works
An outdoor unit connects to one or more wall, ceiling or floor heads through a small line set. Each head has its own controls, so rooms can be set to different temperatures.
Good fits
Older homes without ducts, garage conversions, additions, accessory dwelling units, studios and bonus rooms are all common uses.
Replacing wall heaters
Mini-splits are a common upgrade from old gas wall heaters or electric baseboards, adding cooling as well as more even heat.
Clean air
Indoor heads have washable filters. They catch dust but aren't a substitute for a good whole-house filter during smoke events.
Placement
Heads go high on a wall where air can spread across the room. The outdoor unit needs a solid base and clear space around it.
Permits
Electrical and refrigerant work usually needs a permit. Your contractor should handle it.
Looks
Line sets can run through closets or along the outside in tidy covers, which helps in heritage homes.
Cleaning
Wash the indoor filters every few weeks when the system runs a lot, and have the coil and blower cleaned if airflow drops or a smell develops.

Quiet running
Indoor heads are quiet, which suits bedrooms and home offices.
Heating on cool mornings
On foggy mornings, heads in the rooms you use can take the chill off quickly without warming the whole house.
