A/C Installation & Replacement, done honestly in Sebastopol.

A new air conditioner in Sebastopol should be sized to the house, not copied from the label of the old one. With fog-belt cool summers and damp winters, an undersized system runs itself to death and an oversized one short-cycles without ever dehumidifying properly. We start every Sebastopol installation quote with a real load assessment of your home.

Around older farmhouses and 70s-era homes, we regularly find ductwork that undoes good equipment — leaks, crushed runs, and undersized returns. Because damp shade is hard on heat exchangers and venting, we inspect the whole airflow path before quoting, so the new system actually delivers its rated comfort and efficiency.

Every installation includes permits where required, clean workmanship, and a walkthrough of your new system in plain language. As a triple-licensed contractor (C-20 HVAC, C-10 Electrical), we handle any electrical circuit work in the same job — no second contractor to schedule.

A right-sized system in Sebastopol pays you back every month it runs. We factor in your insulation, windows, and the way fog-belt cool summers and damp winters loads a home before recommending a size and efficiency level — then we quote the equipment plainly, note any rebates or incentives that currently apply, and put the whole project, timeline included, in writing. Installation day ends with a walkthrough so you actually know how to run your new system.

Do I need to replace ducts when replacing my A/C in Sebastopol?

Not always. We inspect your ducts first; if they're sound, we say so. If they leak enough to waste the new system's efficiency, we show you and price the fix separately so you can decide.

How long does an A/C installation take in Sebastopol?

Most straightforward replacements are completed in a single day. Jobs that involve ductwork, electrical, or a switch to a heat pump can run longer — your written quote states the timeline before we begin.

Are there rebates for a new A/C in Sebastopol?

Sometimes — utility and state incentives change through the year. We tell you exactly what applies to your Sebastopol project at quote time, rather than promising savings that may not exist.
