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.

“Euler and his team were able to replace our 23 year old attic Carrier furnace after our existing units 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 did a great job explaining what failed and why a replacement was needed. Good price too.”

“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.”

Before you decide

Clear language before a big decision.

Heat exchanger

The component inside a furnace that transfers heat from combustion gases to the air circulating through your home. A cracked heat exchanger is a carbon monoxide risk and typically requires furnace replacement.

Flame sensor

A safety device in a gas furnace that detects whether the burner is lit. A dirty or failing flame sensor causes the furnace to shut down shortly after igniting.

Frequently Asked Questions

Most furnace repairs from EVS range $200–$900 depending on the part and labor. Diagnostic fee is applied to the repair if you proceed.

If your furnace is under manufacturer warranty (typically 5–10 years for parts), parts may be covered. Labor and diagnostic fees are separate. EVS will check your warranty status before any work.

Yes — in Santa Clara County, a permit is required for any furnace replacement. EVS handles all permits as part of the installation process.

EVS works on Carrier, Lennox, Trane, Goodman, Rheem, Bryant, American Standard, and most major brands. If EVS can't repair your specific unit, they'll tell you honestly — no upselling.

If the repair costs more than half the price of a new furnace, or if your furnace is over 15 years old with recurring problems, replacement is typically more cost-effective. EVS will give you both options with transparent pricing — no pressure.

Yes. Same-day emergency service available. Call (408) 300-8254.

Homeowners insurance typically covers sudden damage (like a motor burning out) but not wear-and-tear repairs. Check your policy or ask EVS when they diagnose the issue.

Bay Area Specifics

Same-Day Service Coverage

EVS provides same-day furnace repair in Santa Clara (HQ), San Jose, Sunnyvale, Mountain View, and Los Gatos. Cupertino, Palo Alto, Campbell, and Milpitas — call to check availability. Direct response, no call center routing.

Emergency Heating Repair

Bay Area furnace emergencies don't wait for business hours. A failed furnace during a cold snap needs fast response. EVS prioritizes emergency calls and offers same-day service when available.

Older Home Challenges

Many Bay Area homes (pre-1970) have older furnaces, 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.
