Furnace Cleaning in Sunnyvale, CA

What furnace cleaning actually involves

Power goes off at the switch and the breaker. Gas is shut at the valve. The burner compartment comes open first. Burners lift out and get brushed clear of rust flake and lint. The flame sensor is scuffed with an abrasive pad, not sandpaper. Igniter and inducer wheel get checked. Pressure switch hose gets checked too. Then the blower assembly slides out. The wheel is cleaned vane by vane, because dust packs the blades and cuts airflow. Cabinet and base get vacuumed. Return side gets vacuumed last.

Furnaces here load up for predictable reasons. Hall return filter slots in the 1950s-70s tracts are often undersized, so air slips around the filter instead of through it. That dust lands on the blower wheel and the coil above it. Attic furnaces pull worse. Disconnected boot-to-register joints feed attic insulation fiber straight back into the return.

Foothill-adjacent homes add rodent nesting in the burner area and crawlspace runs. Wildfire-season ash shows up as fine gray film inside the cabinet.

Cleaning will not fix a cracked heat exchanger or a failed control board. We say so instead of cleaning around it. Pull your filter and shine a light at the blower wheel. Furred blades mean it is time.
