Annual heater maintenance for Los Angeles homes.

Heater maintenance in Los Angeles — what we actually check

Los Angeles winters are mild but not trivial — and a heating system that sat idle all summer needs a real inspection before you need it. HVAC in LA performs a comprehensive furnace and heat pump tune-up that goes well beyond a filter swap.

The most dangerous thing to skip: heat exchanger inspection. A cracked exchanger can allow carbon monoxide into living space with zero visible warning signs. We check it every time.

What's covered in a heater tune-up

• Heat exchanger inspection — critical carbon monoxide safety check
• Burner cleaning and flame inspection — proper combustion, correct color
• Ignitor and flame sensor test — prevents no-heat calls on cold nights
• Gas pressure verification — confirm correct manifold pressure
• Flue and venting inspection — confirm proper exhaust draft
• Blower motor and belt check — airflow, amp draw, lubrication
• Filter inspection — replace or note for homeowner action
• Thermostat test and calibration — confirm accurate temperature control
