Call (408) 300-8254. We answer or call back within 2 hours. Tell us what your AC is doing — or not doing. Same-day emergency service during heat waves.
We come to your home, inspect the unit, run electrical diagnostics, measure refrigerant pressures, and identify the actual cause — not just the symptom. You hear what we found and why.
You get a written repair estimate with: the problem identified, parts needed, labor, timeline, and total price. If replacement makes more sense, we explain why — honestly.
We repair the system once you approve the estimate. We test it under load to confirm proper operation — superheat, subcool, amp draw, temperature split.
We check in to make sure the repair held through the next hot day. If something's wrong, we come back. Local service support — not a call center.

Customers remember the details: showing up, explaining the options, protecting the home, and standing behind the system later.
“We converted our home from a gas furnace to a full electric heat pump system and upgraded to a two-zone setup, giving each floor its own temperature control. EVS guided us through every step, explained our options clearly, and made a complicated project feel straightforward. The installation was clean and completed with a high level of craftsmanship — and their pricing was the most competitive of all the quotes we received.”

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

“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, no upselling on things we didn't need. If you need HVAC work done right, call EVS Mechanical.”

“I called EVS for a regular furnace service and they were here very quickly. They performed the service in one day and also discovered the very old condensate pump was not working properly causing water to pool around the furnace. They replaced the pump the next day. Would definitely use their services again.”

“Euler and his team were able to replace our 23 year old attic Carrier furnace after our existing unit's heating chamber failed. I called him at 10am, and he was at my house by 11am, diagnosed the issue and found a new replacement unit and had it installed by 4pm. Very friendly and great price too.”

“We had a great experience with Euler at EVS Mechanical installing a heat pump heating and A/C system in our home. He was professional, knowledgeable, and easy to work with from start to finish. The installation was clean and efficient, and the system works beautifully. Highly recommend!”

“I had a great experience with Euler & Axel. They came promptly to check my AC issue and quickly assessed the problem. I really appreciated that I had already received a clear quote upfront, so there were no surprises. They also went above and beyond by helping with my dryer. Professional, reliable, and efficient.”

“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.”

“Excellent experience with Euler. Very professional, punctual, knowledgeable, and genuinely helpful. The installation was completed on time with an exceptionally clean job. Nearly a year after the installation, I contacted him about a repair issue. He fixed the problem without any hassle. Highly recommend.”

Most AC repairs come down to one of a handful of common parts — capacitors, contactors, fan motors, thermostats — and those repairs are typically the lower end of the range. Refrigerant leak repair or compressor work is higher. EVS provides a written estimate before any work begins — no surprise charges. Call (408) 300-8254 for a current quote on your situation.
Yes. Same-day AC repair is available across Santa Clara, San Jose, Sunnyvale, Mountain View, Palo Alto, and Los Gatos when calls come in early enough. During Bay Area heat waves we prioritize calls where indoor temperatures climb above 85°F. After-hours and 24/7 emergency service available — call (408) 300-8254 first, we'll tell you straight whether we can be there today.
This is one of the most common AC failures in the Bay Area, especially after a stretch of hot days. The most likely culprits are a failed run capacitor (the small can-shaped part that gives the fan and compressor their starting boost) or a pitted contactor (the electrical switch that engages the outdoor unit). Both are low-cost parts and a same-day repair when diagnosed correctly. Call (408) 300-8254 — don't keep cycling the thermostat trying to make it start, you can damage the compressor.
Watch for: warm air from vents, weak airflow, unusual noises (grinding, squealing, clicking), higher energy bills without a usage change, moisture or leaks around the indoor unit, bad smells from vents, or the system cycling on and off frequently. Any of these means call EVS for a diagnostic. Catching issues early prevents the expensive breakdowns.
Bay Area AC issues include: capacitor and contactor failures (heat kills them every summer), refrigerant leaks (warm air, ice on lines), clogged condensate drains (moisture buildup near indoor unit), dirty evaporator coils (reduced cooling), undersized systems for valley heat (San Jose, Cupertino), oversized systems for fog-belt homes (no dehumidification), and electrical issues from older panels. Regular maintenance prevents most of these.
Repair if the unit is under 10 years old, the repair cost is less than 50% of replacement cost, and it's a single component failure (capacitor, contactor, fan motor). Replace if the unit is 12+ years old, uses R-22 refrigerant (phased out), needs frequent repairs, or has a major component failure (compressor, condenser). EVS gives you an honest assessment — we do both repair and replacement, so we're not pushing either direction.
Yes. We service Carrier, Bryant, Day & Night, Trane, Lennox, Goodman, Rheem, Daikin, Mitsubishi, Fujitsu, and Bosch — central AC, heat pumps, multi-zone mini splits, and light commercial. Day & Night units (a Carrier sibling brand) are common in the South Bay and we work on them every week.
Yes. We service single-head, multi-head, and ceiling cassette mini splits from Mitsubishi, Daikin, Fujitsu, Carrier, and Bosch. Multi-zone systems — common in ADUs, additions, and older Bay Area homes without ductwork — get the same diagnostic and repair process as central AC.
Look for a California C-20 HVAC license (verify at cslb.ca.gov), local reviews on Google and Yelp, upfront pricing before work starts, proper insurance and bonding, and a real local address — not a national call center. Ask about diagnostic fees, warranty on repairs, and response time. EVS offers 1–2 hour callbacks and transparent pricing — no hidden fees.
EVS provides same-day AC repair across Santa Clara (HQ), San Jose, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Menlo Park, and Mountain View. After-hours and 24/7 emergency calls handled during summer heat waves. Cupertino, Campbell, Atherton, and Milpitas — call to check availability.
Many Bay Area homes — especially ADUs, garage conversions, and additions — run on multi-zone ductless systems. EVS services Mitsubishi, Daikin, Fujitsu, and Carrier mini splits and multi-zone systems. Single-head, multi-head, ceiling cassette — we work on all of them.
Many South Bay homes (built 1950s–1980s) have undersized electrical service, original ductwork, and condenser pads in tight side yards. EVS has experience diagnosing in these conditions — and won't quote you a full system replacement when a $25 capacitor will fix it.
- **Capacitor failure after a hot weekend.** The most common emergency call we get in July and August. Heat kills capacitors faster than any other component. - **Refrigerant leaks on R-22 systems.** R-22 was phased out in 2020. Refilling is now expensive. If your AC is leaking R-22, replacement is usually the better move. - **Dirty condenser coils.** Bay Area pollen, construction dust, and yard debris coat outdoor coils every summer. Easy maintenance fix that prevents major repairs.
