San Francisco
HVAC & appliance repair

Most San Francisco homes were built before central air conditioning existed, which is why so many flats and Victorians still run on a wall or floor furnace instead of ducted heat. Fog belt neighborhoods barely need cooling; the sunnier east side increasingly does, and we install mini-splits for exactly that gap.

Local calls

What we see most in San Francisco.

Wall or gravity furnace won't light

Common in pre-war flats — the pilot, thermocouple or gas valve on an in-wall unit, not a full furnace swap.

No ducting for AC

Most SF buildings were never plumbed for central air. A ductless mini-split is usually the fastest, least invasive fix.

Appliance access in narrow flats

Stacked laundry, tight kitchens and steep stairs in older buildings — we bring the right dollies and know the buildings.

Questions

Before you call.

Do you work on the wall or gravity furnaces common in SF flats?

Yes — they're a large share of our heating calls in the city. Parts for older units are usually still available; when they're not, we requote for a direct wall-furnace replacement.

My building has no central AC — what are my options?

A ductless mini-split is the standard fix for SF flats: one small line set through an exterior wall, no ductwork, and it heats as well as it cools.
