“EVS Mechanical is a great HVAC company! They were very professional, on time, explained everything and had a very competitive price. They found asbestos and we had to replace our entire furnace and duct work — it was done in a week. They filed the permits and handled everything. I highly recommend them.”

We Serve the Bay Area, Not Shareholders
Family-run HVAC contractor that puts community needs over profits. No sales pressure, no add-ons, no jobs we won't take if it's what you need.
Owner-Operated, Not a Sales Company
You work directly with the owner who designs your system and leads the installation. No middlemen, no sales quotas, no pressure. We're the actual technicians doing the work.
Fixed Quote, Zero Add-Ons
The quote we give is what you pay. No surprise charges, no hidden fees. We custom-design every system instead of using generic templates that pad the price.
We Take the Jobs Others Won't
Tight crawl space? Old wiring? Complex retrofit? We don't turn down difficult installs if it's what you need. Community needs come first, not just easy, profitable jobs.
