Furnace Repair Near Brea, California
Furnace Repair Near Brea, California
Restore safe, reliable heat — quickly.
When your furnace struggles or won’t start, we evaluate the entire heating system: thermostat and low-voltage controls, electrical, gas pressure, ignition sequence, flame sensing, burners/heat exchanger, blower/inducer motors, filter/airflow, static pressure, and safety switches. Then we explain what failed and the smartest way to fix it.
Many common furnace repairs can be completed the same day, depending on parts and unit condition.
Common Furnace Problems We Fix
- No heat at all / furnace won’t start
- Blows cold air or won’t reach set temperature
- Short cycling (keeps turning on/off)
- Ignition issues: hot surface igniter or spark won’t light, pilot won’t stay lit

- Blower or inducer motor won’t run, squeals, or trips breaker
- Limit/pressure switch faults and lockouts

If we find a cracked heat exchanger or unsafe condition, we’ll document it and discuss safe next steps.

Repair vs. Replace — How to Decide
Consider replacement when:
- The furnace is 10–15+ years old and the repair is major (heat exchanger, control board, motor)
- You’re facing frequent breakdowns or uneven comfort
- Efficiency is poor and bills are rising
- Parts are obsolete or the system is unsafe to run
Otherwise, a targeted repair can restore reliable heat at a lower cost. We’ll price both so you can decide.

Furnace Repair FAQs
Why does my furnace run but blow cold air?
Common causes include ignition or flame-sensing issues, a tripped limit switch from airflow problems, or a control board fault. We’ll test and pinpoint the cause.
The furnace keeps turning on and off. What’s happening?
That’s short cycling — often airflow restrictions (dirty filter, blocked coil/vents), overheating/limit trips, or thermostat/control problems.
Is a cracked heat exchanger dangerous?
Yes. It can allow combustion gases into the airstream. If we suspect a crack, we’ll document it and discuss safe options.
How fast can you fix a no-heat issue?
Many common failures (igniters, sensors, capacitors, simple controls) are same-day fixes, depending on parts and system condition.
Do you work on all major furnace brands?
Yes — we service most brands commonly installed in Southern California homes.
