Furnace Repair in the East Bay
Most East Bay homes are heated by a gas furnace — and most furnaces fail the same predictable ways: ignition problems, failed blower motors, dirty flame sensors, cracked heat exchangers, control board faults. We've seen and fixed every one of them across Alameda and Contra Costa County.

Why Oren's HVAC Services for furnace repair
Furnace repair is also safety work. Gas, combustion, and venting demand a licensed professional. Oren's HVAC Services is a licensed HVAC contractor, and we check combustion safety on every furnace visit.
Combustion safety on every call
We inspect the heat exchanger, venting, and gas connections as part of every furnace diagnosis — protecting your home from carbon monoxide risk, not just restoring heat.
Experience across every furnace era
Ignitors, flame sensors, inducer motors, gas valves, control boards — we carry the common parts and know the common failure patterns, from new high-efficiency units to the older furnaces still running in East Bay homes.
Repair-or-replace honesty
A cracked heat exchanger on a 20-year-old furnace is a replacement conversation. A failed ignitor on an 8-year-old one is a simple repair. We tell you which is which, straight.
Done right the first time
We fix the actual cause, not just the symptom, and verify the system before we leave.
HVAC Emergency?
No heat. No cooling. No waiting until morning.

Popular service areas
Furnace Repair — common questions
Why does my furnace turn on and then shut off right away?
Short-cycling is most often a dirty flame sensor, restricted airflow from a clogged filter, or an overheating limit switch. It's one of the most common furnace calls we run, and usually a same-visit fix.
Is a cracked heat exchanger really serious?
Yes. A cracked heat exchanger can allow carbon monoxide into your home's air. If we find one, we'll show you the evidence and walk you through the options — it's the one furnace problem you should never run the system with.
Do you repair older furnaces?
Yes, including older standing-pilot models common in the East Bay's older Oakland and Berkeley housing stock. If parts are no longer available or the repair doesn't make economic sense, we'll tell you honestly.
Can you repair my furnace at night or on a weekend?
Yes — furnace failures are an emergency, and we offer emergency HVAC service. Call (800) 974-5349.
