What Is Furnace Repair?
Furnace repair covers diagnosing and fixing problems with your home's gas or electric furnace — from ignition failures and blower motor issues to cracked heat exchangers and thermostat faults. EVS handles residential and light commercial furnace repairs for all major brands. Your furnace is the most expensive mechanical system in your home. Don't wait when something goes wrong.
When to call about yours:
- No heat — furnace turns on but blows cold air
- Strange noises — banging, rattling, screeching, or whistling
- Pilot won't stay lit or ignition system fails repeatedly
- Cold spots — some rooms heat, others don't
- Carbon monoxide detector goes off
- Unusual smells — gas, burning dust, or musty odors from vents
- Frequent cycling — furnace turns on and off too often
- Furnace is 15+ years old with recurring problems
Who this is for: Homeowners in Santa Clara, San Jose, Sunnyvale, Mountain View, Palo Alto, Los Gatos, Cupertino, Campbell, Milpitas, Saratoga, Los Altos, and Santa Cruz. Residential and light commercial.

From first call to finished job
02
Diagnostic Visit
We come to your home, inspect the furnace, run diagnostics, and identify the problem. We diagnose based on load calculations and airflow specs — not a checklist.
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 honestly.
04
Repair (with your approval)
We repair the furnace 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.”

“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.”
