Collapsed flex. Torn liner. Insulation shedding into the airstream. Every foot of that duct was leaking conditioned air into the dirt — and the homeowner was paying for it.

We pulled all of it. New sized duct, properly supported, sealed at every connection, hung so it stays that way in year ten.

Your equipment is only as good as what you attach it to. We're a Mitsubishi Electric Elite Diamond Contractor, and we build the whole system — not just the box.
Residential and light commercial. Sonoma County and beyond.

Elite Diamond Contractor isn't a sticker you buy.

It's Mitsubishi Electric's highest dealer designation — earned through advanced technical training, install quality, and a track record they actually audit. Fewer than 5% of contractors nationwide hold it.

What it means for you: extended warranty coverage you can't get anywhere else, factory-level design support on complex jobs, and technicians trained specifically on this equipment rather than treating it like a generic heat pump.

We chose to specialize. Residential and light commercial, start to finish.

Look up. Find the supply air.

Linear slot diffusers, laid into a tongue-and-groove ceiling so the grain runs uninterrupted. No white plastic register breaking up the line. No compromise on airflow to get there.

This is the part of the job that happens months before install — coordinating with the architect and framer so the ductwork lands exactly where the design needs it to.

Design meets comfort.

A quiet look at something we're proud of.

Every duct, chase, and pe*******on on this Marin County project was designed before framing started.

Watching it come together exactly as designed never gets old.

Beat the heat before it beats your A/C.

A few minutes of maintenance now can save you a no-cool emergency later. Save this checklist and work through it before the next heat wave hits!

Wildfire smoke doesn't stay outside.

Even with windows closed, fine smoke particles and odor work their way into your home through doors, vents, and small gaps — and a standard HVAC filter isn't built to stop them.

Here's what actually helps:
✅ A high-MERV pleated filter captures the fine particulate matter (PM2.5) that wildfire smoke is made of
✅ An activated carbon filter tackles what particulate filters can't — the smoke smell — by adsorbing odor molecules instead of just trapping particles
✅ Running your HVAC fan on "on" instead of "auto" during smoke events keeps air continuously cycling through the filter
✅ Check your filter more often during smoke season — heavy smoke clogs filters faster than normal use
If you're in a wildfire-prone area, pairing particulate + carbon filtration is the most effective way to keep your indoor air breathable when it's bad outside.
