Since 1925 we have been serving the East Bay Area, beginning as a furnace manufacturer, installer and custom fabrication shop. After World War II, we stopped manufacturing the Golden Gate furnace due to cost and competition of mass produced furnaces.

With our solid reputation intact, we began installing furnaces built by major manufacturers and continued with our custom fabrication services. Nearly 80 years later, we are still providing high-quality service and products.

Today we specialize in residential and light commercial HVAC system. Our service area has grown to include Alameda, Oakland, Piedmont, Berkeley, El Cerrito, San Leandro and nearby areas.

Our service department is well known for maintaining and repairing many different kinds of heating and cooling systems, old and new alike. We also have an on-site fabrication shop where we can fabricate everything from gutters, downspouts, plenums, roof flashings to custom copper and stainless back splashes, hoods and standing seam roofs.
