Ductless heating in a mild winter
Heads heat. They are not decorative.
A Lafayette addition can heat on a mini-split all winter. If the head is heat-pump capable, use it that way — that is why we installed it.
A mini-split is the honest answer when ducts cannot reach an addition, ADU, or garage conversion cleanly.
This is a seasonal East Bay issue. Orinda sees it on a different calendar than the coast.
We size the head to the room, check outdoor clearance and electrical, and estimate in-home for free. One oversized head short-cycles just like a bad central unit.
We map ductless heating California to the actual failed part or design limit. Age of the system is a data point, not the diagnosis.
You approve any repair after the findings are written down. Diagnostic visits are a flat $69. New installation estimates are free in-home with a load calculation — not a number invented from square footage on Zillow.
Extending leaky ducts 40 feet through an attic is often worse comfort per dollar than a ductless head.
A company that skips testing on ductless heating California will skip it on the next call too. We would rather lose a job than install the wrong thing.

OTTER HVAC is based at 2939 Santos Ln, Walnut Creek. Orinda, Walnut Creek, and Lafayette are regular routes, along with the rest of our listed East Bay cities. Hours are 7am–5pm, seven days a week. We do not advertise 24/7 because we do not staff a night shift.
Inland heat (Pleasanton, Livermore, Concord) and marine air (Alameda, Daly City) are different loads. A note written for Orinda is not automatically right for a fog-belt house. We treat them that way.

Frequently asked questions
What do you test on a ductless heating California visit?
We size the head to the room, check outdoor clearance and electrical, and estimate in-home for free. One oversized head short-cycles just like a bad central unit. The visit is a flat $69. Repair work starts only after you approve the written findings.
Will you quote ductless heating California from a photo?
No. We do not price ductless heating California from a driveway photo. $69 diagnostic, then a quote — or a free in-home install estimate if replacement is the honest path.
