What's different about an Santa Clara install
You talk to the owner. The owner runs your install — no subcontractors, no finger-pointing.
Based in Santa Clara at 3674 Bassett St. Serving our neighbors directly.
We work with the City of Santa Clara Building Division every day.
Understanding of SVP's specific rebate and efficiency programs.
All 9 HVAC services available, from furnace installation to commercial HVAC.
Proper sizing for Santa Clara's hot summers.
Every Santa Clara HVAC installation requires a permit. EVS handles it all.
Euler Vargas oversees every install — you work with the owner, not a sales rep or a call center. The team that quotes the job is the team that does the work.
We carry Carrier, Bryant, Goodman, Daikin, Lennox, Mitsubishi, Bosch, and Fujitsu — and we're not factory-authorized to push any single one. You get the unit that fits your home and budget, not the one a dealer is incentivized to sell.
Your equipment warranty stays the manufacturer's warranty — it doesn't disappear if you skip a recurring maintenance contract. We offer maintenance because it extends the life of your system, not as the price of keeping your coverage.
No add-ons, no upselling on equipment you don't need. We're not a sales company — we're the ones who actually do the work.
Full responsibility from design to installation, including the difficult ones other companies pass on. We support on-budget work for churches, veterans' facilities, and charities.

Why Santa Clara is different
Housing stock in Santa Clara
This is our home city — we're based on Bassett Street. Santa Clara's stock runs from 1890s bungalows through Eichler co-ops to towers near the stadium. The stock drives the system:
Radiant-slab heat (gas-fired boiler), no ductwork, post-and-beam/CMU, flat roofs — a ductless mini-split or ductless heat pump is the retrofit, and the NRHP listing can trigger review for exterior condenser placement. (The Forest Park ranch tract nearby also has slab + radiant floor heat and no ducts, so ductless is the retrofit there too.)
Attic and crawlspace, so ductwork is feasible, with typically 100A panels.
Pre-WWII stock with knob-and-tube legacy; the city's Historic Combining District and 100-foot Areas of Historic Sensitivity apply (not a formal district, but inventory protections).
What Santa Clara homeowners ask
For an average Santa Clara home, AC installation starts at $4,800 — the final number depends on the system, brand (Carrier, Bryant, Goodman, Daikin, Lennox), and what your home needs. The price goes up with an electrical panel upgrade, new or replacement ductwork, or a system redesign; it comes down on a direct one-to-one equipment swap with easy access and no redesign. We run a Manual J load calculation during the site visit so the system is sized to your home, not a square-footage guess, and the written quote is the price you pay — no upselling on things you don't need.
Yes — and Santa Clara is our home turf. We're based at 3674 Bassett St in Santa Clara, so we're minutes from anywhere in the city and offer same-day HVAC, heating, and AC repair. A real customer called us at 10am, we were at his house by 11am, and the failed system was installed by 4pm. Call (408) 300-8254.
A ducted heat pump (1.5–3 tons) for an average Santa Clara home starts at $5,000; ductless mini-split systems are priced separately by zone. The final number depends on whether it's ducted or ductless, the brand (Carrier, Mitsubishi, Daikin, Bosch, Lennox), and whether we're replacing a gas furnace with a full electric heat pump — an electrical panel upgrade or new ductwork adds to the total, a direct one-to-one swap keeps it down. The quote starts with a Manual J load calculation and is the price you pay — no upselling.
Yes. We repair all heat pump brands across Santa Clara — refrigerant leaks, compressor failures, reversing-valve issues, defrost problems, and heat pumps that heat but won't cool (or vice versa). We diagnose same-day and give you a clear, written quote upfront before any repair.
Gas furnace replacement in Santa Clara starts at $2,800 — the final number depends on the brand, efficiency rating, and whether the flue or electrical needs updating; a direct one-to-one swap keeps it down, a flue or electrical update adds to it. We size the furnace with a Manual J load calculation and give you a written quote upfront — the price you pay, no surprises.
Yes — and Santa Clara has a unique advantage. Most of the city gets electricity from Silicon Valley Power (SVP), a municipal utility separate from PG&E, which runs its own energy efficiency programs. Heat pump upgrades can also stack statewide TECH Clean California incentives and local utility rebate programs. We walk through what applies during the estimate.
Yes — we're based in Santa Clara and serve every neighborhood, from the Mission area and Old Quad to Rivermark, the Wise area, and the industrial parks. Being local means fast, live callback (no call centers) and same-day repair availability across the city.

“EVS Mechanical made what could have been a stressful process incredibly smooth. They diagnosed and repaired our HVAC system quickly and got everything running again. They didn't just do the work — they made sure we understood what was happening and why. Honest pricing. They didn't try to upsell us on things we didn't need. Really appreciated that they were on time and ready to work. If you need HVAC work done right, call EVS Mechanical. You won't be disappointed.”

“The EVS Mechanical team were great! The EVS team showed up on time and completed the heat pump installation in one day as promised. Axel stayed on top of the whole process from quote to final inspection and communication was awesome. EVS made the whole process seamless. The pricing was more than fair for the quality of work we received. Every person on the crew was courteous and professional. When the installation was finished I couldn't tell they had been in the house. Thanks to EVS Mechanical we have heating and air conditioning again making for a comfortable house. I strongly recommend EVS Mechanical for all your HVAC needs.”

“Really impressed with EVS Mechanical. They earned every one of these five stars. The heat pump they installed has been incredibly efficient — our energy bills have actually dropped. Punctuality was great — they showed up exactly when they said they would. Appreciated how careful they were with our home during the installation. Would absolutely recommend EVS to anyone in the Bay Area. Thank you, EVS Mechanical, for the outstanding work!”
