We serve companies of all sizes, from individual proprietorships to major corporations and institutions in a variety of industries. Having the right company installing and servicing your heating, air conditioning and indoor air quality equipment is just as important as choosing high-quality products.

The right heating and cooling system will save you energy and money. Atlas Heating and Ventilating has the knowledge and expertise to provide you with both, serving the San Francisco Bay Area and Penisula, with over 100 years of combined business experience.
Services
As the oldest heating and ventilating company in the Bay Area (founded in 1908), Atlas has been as much a part of San Francisco as the cable cars and Golden Gate Bridge, helping to rebuild the City after the 1906 earthquake. Atlas' history is a veritable history of the furnace itself. In 1908, most homes were heated by pot-bellied stoves or kitchen ranges.
Heating and cooling means more than just keeping your house warm in winter and cool in the summer. A good system should protect you from allergens and combat mold. It should also save energy and lower your gas and electricity bills. We only install top-quality, high-performance systems that meet the specific needs of your home, family and climate.
Atlas Heating & Ventilating is a leading contractor providing high-efficiency packaged rooftop units, split systems, HVAC controls, furnaces and indoor air quality products for the commercial industry. Our customers benefit from our years of experience, advanced technology, quality products and unsurpassed customer service.

Blower has been replaced three times! Three times since 1968! I've only had the place since 2012 but the last time a blower motor was installed was 1989, that would be motor #2 subsequently had a new one installed in Pacifica. Judging by the date you guys did all the "new" Dolger" homes in Fairmont West.

Called to ask them to come out and look at a beater issue in one bathroom and they said they would have someone call me back. Nobody called and I guess they are either too busy or didn't want to help me with smaller problems. Giving them 1 star, because I pretty much had only one interaction and was not a good one. Update: I called back Hugh who responded to me and this man helped me with open arms. I appreciate it Hugh.

Fabrizio did an excellent job correcting the ventilation on my heater and installing a new thermostat. He gave me piece of mind by showing me that there was no longer any level of carbon monoxide detected after his repairs. Went above and beyond and cleaned up thoroughly afterwards. A+!

Excellent service. Just had to wait awhile for an appointment to diagnose problem. Once out to the property they fixed issue promptly on an older system.

I have been going to Atlas Heating since 2007. They are fantastic. Very reliable. They do my furnace inspection every year and I have never had any issues because of their fine service.

They were able to come to my house the same day I called and fix our furnace's pilot light on the spot.

The Atlas Heating and Ventilating installed a new heating unit in my commercial building and they also rewired and repaired my other heater on the roof. I am super happy with their service and staff, they are very professional and honest and I recommend them to everyone that is looking for a commercial or residential heating and cooling system. They take care of business in a short time and they won't empty your pocket or give you the run around like some companies do. Thanks very much Atlas Heating and Ventilating.

Terrific Service and expert technical skills. Kathy was a pleasure to work with and schedule my appointment. Needed HVAC certified inspection per PG&E. She called me back and got me an earlier appointment when someone cancelled. Technician Mike was great. Inspected my wall heater and told me more about it that I needed to know. Scheduled a second visit to get it thoroughly cleaned. Again Mike was great. Also installed a new thermostat to replace my old finicky one. Atlas is great!
