What's different about an Palo Alto install
You talk to the owner. The owner runs your install — no subcontractors, no finger-pointing.
Based in Santa Clara, just up the road from Palo Alto.
EVS has experience working in Palo Alto's older homes and navigating historic district requirements.
Every quote starts with a Manual J calculation for proper sizing.
Palo Alto has strict permitting — EVS manages the full process.
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 Palo Alto is different
Housing stock in Palo Alto
Palo Alto's stock runs from 1890s Craftsman bungalows through flagship Eichler tracts to pre-war historic districts. The stock drives the system:
Slab with radiant-heat tubing embedded in the concrete, flat roof, post-and-beam, and no attic, basement, crawlspace, or ductwork — a ductless mini-split or ductless heat pump is the retrofit. Original panels are often 50–100A, and upgrades to 125–200A are common but constrained. Greenmeadow and Green Gables are National Register–listed tracts, and the city adopted voluntary Palo Alto Eichler Neighborhood Design Guidelines in 2018.
Wood-frame with attics and crawlspaces, so ductwork is feasible — but Professorville is a National Register Historic District, so exterior equipment placement and roof penetrations can trigger historic review.
No in-city hillside; the foothills are unincorporated Stanford land.
What Palo Alto homeowners ask
A ducted heat pump (1.5–3 tons) for an average Palo Alto home starts at $5,000; ductless mini-split systems are priced separately by zone, starting around $1,900 per zone. The final number depends on whether it's ducted or ductless, the brand (Carrier, Mitsubishi, Daikin, Bosch, Lennox), and whether we're converting a gas furnace to 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. We run a Manual J load calculation so the system is sized to your home, and the written quote is the price you pay — no upselling on things you don't need.
Yes — Old Palo Alto, Crescent Park, Professorville, Barron Park, Midtown, and the Charleston Meadows area. We're based in Santa Clara just up the road, with fast, live callback (no call centers). Properties in Palo Alto's historic districts may need additional design review for exterior equipment placement, and we plan for that during the estimate.
AC installation in Palo Alto starts at $4,800 for an average home — the final number depends on the system, brand (Carrier, Bryant, Daikin, Lennox, Goodman), and whether your home needs an electrical panel upgrade or new ductwork; a direct one-to-one swap with easy access keeps it down, a panel upgrade or new ductwork adds to it. We do a Manual J load calculation so the system is sized to your home, and the written quote is the price you pay — no upselling.
Yes. We run same-day AC repair across Palo Alto for cooling failures, warm-air issues, refrigerant leaks, and frozen coils. 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 if your AC is out in Palo Alto.
Yes — and Palo Alto is different from most of the Bay Area. Palo Alto has its own municipal electric utility (City of Palo Alto Utilities, CPAU) alongside PG&E gas, and CPAU offers its own energy efficiency rebates for qualifying HVAC equipment. Heat pump upgrades can also stack statewide TECH Clean California incentives and local utility rebate programs. We walk through what applies during the estimate.
HVAC repair in Palo Alto starts with a diagnostic visit; the repair cost depends on the failing part — a capacitor, contactor, or thermostat is a smaller fix, while a compressor, coil, or board is a larger one. You get a clear, written quote upfront before any work, so there are no surprises. Most repairs are completed same-day.
Yes — HVAC installations and replacements in Palo Alto require a permit through the City of Palo Alto's Development Center, and EVS pulls the permit and manages inspection scheduling. Historic-district properties may need additional design review, which we plan for upfront. You don't deal with the city.
