Heating & Air Conditioning

Golden Gate takes pride in our custom furnace installations. Each job is unique because we customize the heating system to fit your space. We fabricate all our own plenum and rigid pipe if the space requires it. We meet with you one-on-one to see what we can do to make your system suit your needs.

We install only the best brands in the industry and back them with manufacturers warranties, as well as our limited labor warranties.

We are dedicated to each and every one of our customers. Once you have a system installed by us, you can count on us to service it for years to come.

90 Years of Experience

Golden Gate Sheet Metal Works has been serving the East Bay Area since 1925, beginning as a furnace manufacturer, installer and custom fabrication shop until the mid 1940’s. After World War II, Golden Gate stopped manufacturing the Golden Gate furnace due to cost and competition of mass produced furnaces. With their solid reputation intact, they began installing furnaces built by other manufactures and continued with custom fabrication service. Nearly 90 years later, Golden Gate is still providing high-quality service and products, and occasionally runs into one of their original Golden Gate furnaces.

We Take Pride in What We Do

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

    Heather Bogue Office Manager

    Heather joined Golden Gate Sheet Metal in 2014. She has a background in customer service and we knew she would be a perfect fit. Heather is our first line of communication with our clients. Her upbeat personality and attention to detail are just a few of her great qualities. She takes excellent care of our customers - just like her family.

“Rudy! Thank you sooo much for fixing my heater and installing that fabulous touch screen. Now my house is nice and warm, just in time for my mom coming to visit. As you know, she thought that my broken heater story was a farce and I was cheaping out by not providing heat when she was visiting..... Now I can prove her wrong! Happy holidays!”

“The company was a pleasure to do business with, and their technician Ernie was an equally wonderful representative of the company. Bridget in the office was so ON THE SPOT with paperwork, that she had copies of all our work, and the rebate forms put together with notes giving me instructions on how to fill out and send in the refunds and rebates.  She made it so simple, I was surprised!  If you want to hire a contractor with confidence, I guarantee that you will NOT regret your decision to hire Golden Gate!”

“I wholeheartedly recommend GGSMW for any heater repairs.  I had unexpected water heater, floor heater and ducting repairs, and Rudy gave me an excellent quote, and followed it up with an outstanding installation.  He brought my system up to code and also took care of all the permitting and City inspection.  My water heater and heater are working much better than before, and the new internal and external ducting looks great!”

“Great local business - turn to them first!”

“Rudy is an awesome technician.  He's very professional, very thorough, very fast, and very personable.  Of all the service technicians I've come across, the people at this shop have been so helpful.”

“Bridget is very helpful in communicating, setting up appointments, and getting transactions done.  I'd highly recommend Golden Gate Sheet Metal to anyone looking to get some HVAC work done.”
