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.

From first call to finished job
02
Diagnostic Visit
We come to your home, inspect the system, run diagnostics, and identify the problem. We'll explain what's wrong and why.
03
Repair Estimate
You get a written repair estimate with: the problem identified, parts needed, labor, timeline, and total price. If replacement is the better option, we explain why.
04
Repair (with your approval)
We repair the system once you approve the estimate. We test the system to confirm it's working properly.
05
Follow-Up
We check in to make sure the repair held. If something's wrong, we come back. Local service support — not a call center.

Clean work. Clear prices. People who answer after the install.
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.”

“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.”

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.
