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 EVS:
- 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.
Why EVS?
Owner-operated, not a call center.
When you call (408) 300-8254, you reach the people doing the work — directly, same day.
Design-first, not template-based.
EVS performs Manual J load calculations, checks proper airflow, and designs the system for your specific home. Equipment lasts longer when it's installed right.
Honest pricing.
The quote you get is what you pay. No surprise add-ons, no "oh wait, you need this too" calls. Final quote given is what customer pays for — no add-ons.
Full responsibility.
One team handles diagnosis, repair, and follow-up. No finger-pointing between a sales company and a separate install crew.
Community-first.
EVS prioritizes needs over profit — including budget-conscious pricing for churches, veterans facilities, and charities.
Our Process
Call EVS
Call (408) 300-8254. We answer or call back within 2 hours. Tell us what your furnace is doing (or not doing). Same-day emergency service available.
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.
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.
Repair (with your approval)
We repair the furnace once you approve the estimate. We test the system to confirm it's working properly.
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.
