What Is HVAC Repair?

HVAC repair covers troubleshooting and fixing any issue with your heating, ventilation, and air conditioning system — whether it's a furnace, air conditioner, heat pump, or mini split. EVS handles both residential and light commercial HVAC repairs, from simple thermostat issues to major component replacement.

When to call about yours:

Your furnace stopped producing heat
Your AC is blowing warm air
Your system is making strange noises
Your energy bills spiked unexpectedly
Your system short-cycles (turns on and off frequently)
You smell gas, burning, or musty odors from vents
Your thermostat isn't communicating with the system
You need a repair second opinion

Who this is for: Homeowners in Santa Clara, San Jose, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Santa Cruz, Cupertino, Campbell, Saratoga, Los Altos, and Milpitas. Residential and light commercial.

What you get from an EVS install

We fix it or we tell you why not.

Some repairs aren't worth doing. We'll give you the honest answer — repair or replace — based on your system's age, condition, and repair cost.

1-2 hour callback.

Call (408) 300-8254. We call back within 2 hours. Same-day service available when possible.

All brands, all systems.

Carrier, Bryant, Goodman, Daikin, Lennox, Mitsubishi, Bosch, Fujitsu — furnaces, ACs, heat pumps, mini splits, commercial units. If EVS doesn't work on it, it's probably not an HVAC system.

Family-run.

Euler Vargas oversees every service call. No subcontractors. No national call center routing you through a menu tree.

Permits handled for repairs that need them.

Most repairs don't need permits, but when they do (gas line work, major electrical), EVS handles the paperwork.

“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.”

“Outstanding service from EVS Mechanical! I called EVS Mechanical on a Saturday afternoon for an emergency HVAC repair on an extremely hot summer day. They showed up within an hour, quickly diagnosed the problem, and took care of it without any drama or unnecessary delays. Most importantly, they made my tenant extremely happy — which, as a property owner, means a lot to me. The price was very reasonable, and there was no back-and-forth, no pressure, and no negotiating. They simply came out, did the job, and took care of the problem. That's the kind of service you hope to find but rarely do anymore. I highly recommend EVS Mechanical. Put these guys on your speed dial. You won't regret it!”

“I called EVS Mechanical at 8:45 pm during a heat wave where the temperature reached 104 degrees in Los Gatos. They were able to get appointment for 10:00 am the following day. The fact that they were so busy with the heat wave was amazing customer service. Euler Vargas who is the owner, called me right on time at 9:45 am and arrived just on time. He fixed the issue very quickly. He and his assistant were very polite. I highly recommend EVS to anyone who is looking for a great HVAC contractor!”

“We had a complicated upgraded heating and new A/C install due to the floor plan of our home. Euler and his team of technicians accomplished both beyond our expectations. Their quote was very competitive and the warranty unbeatable. Euler is both a gentleman and a man of his word standing by his workmanship and factory warranty. When a small Carrier part failed Euler took care of the Carrier paperwork an cheerfully did the replacement as soon as the part arrived. …”

Frequently Asked Questions

We aim for 1-2 hour callback. Same-day service is available when possible. Call (408) 300-8254 and we'll give you an honest timeline based on current workload and urgency.

Yes. EVS repairs Carrier, Bryant, Goodman, Daikin, Lennox, Mitsubishi, Bosch, Fujitsu, and most other residential and light commercial HVAC brands. If we can't repair it, we'll tell you upfront.

Diagnostic fee varies — call for current pricing. Repair cost depends on the problem, parts needed, and access difficulty. EVS gives a written estimate before any work begins. No surprise charges.

General rule: if the repair costs more than half the replacement cost, or if your system is over 15 years old and needs major repairs, replacement is usually better. EVS gives straight advice either way.

Yes. We prioritize emergency calls — no heat in winter, no AC in extreme heat, gas smells, or system failure. Call (408) 300-8254.

Most repairs don't require permits. Repairs involving gas line modification, major electrical work, or refrigerant line replacement may require permits. EVS handles this when applicable.

Yes. EVS repairs mini splits from Carrier, Mitsubishi, Daikin, Fujitsu, Bosch, Lennox, and other brands. Common mini split repairs include refrigerant leaks, compressor issues, and fan motor failures.

Yes. EVS stands behind their work. Ask about specific warranty terms when you get your repair estimate — coverage varies by the type of repair and parts involved.

EVS will tell you honestly. We'll explain why replacement is the better option and provide a quote for a new system. We do both repair and replacement, so there's no incentive to push one over the other.

Bay Area Specifics

Emergency Repairs

Bay Area HVAC emergencies don't care about business hours. A failed furnace during a cold snap or a dead AC during a heatwave needs fast response. EVS prioritizes emergency calls and offers same-day service when available.

PG&E Shutoffs and Power Outages

PG&E public safety power shutoffs (PSPS) can affect HVAC systems. Gas furnaces need electricity for the blower. Heat pumps and ACs need electricity entirely. If you're concerned about power shutoffs affecting your system, ask about backup recommendations.

Older Home Challenges

Many Bay Area homes (pre-1970) have older systems, unique configurations, or systems that have been modified multiple times. Diagnosing these takes more experience than newer tract-home installs. EVS has experience with the full range.

Santa Cruz Mountains and Foothills

Homes in Los Gatos hills, Santa Cruz Mountains, and Saratoga foothills face different conditions than valley floor homes — colder winters, more wildlife interference (nesting in units), and often harder-to-access equipment. EVS services these areas routinely.
