Furnace Cleaning in San Mateo, CA

What furnace cleaning actually involves

Power goes off at the switch and the breaker. Gas is shut at the valve. Doors come off. The burner assembly is unbolted and drawn out. Burner ports and crossovers get brushed and vacuumed. The flame sensor is scuffed with an abrasive pad, not sandpaper. Igniter is inspected, never handled. Inducer housing and pressure switch tubing get checked for lint.

Then the blower. The sled slides out on most units here. Each vane is cleaned individually on a drop cloth. A wheel wiped in place is a wheel half cleaned. Loaded vanes lose grip on air and your registers go quiet. Motor mounts and the run capacitor are looked at while the assembly is out.

Local specifics matter. Many San Mateo furnaces sit in the garage, and the return plenum often draws garage air through unsealed seams. Filter slots are undersized or missing a gasket, so unfiltered air bypasses straight into the blower. Panned floor-joist returns in older homes feed crawlspace dust into the same path. Dust load includes marine salt and bay mudflat silt. Spring pollen and late-summer wildfire soot add to it.

Cleaning will not fix a cracked heat exchanger or a rusted-through cabinet. We say so before touching anything.

What Happens After You Call Us

Step 1

Call and tell us what you're seeing, dust on the registers, weak airflow in the back bedrooms, a dryer that needs two cycles. We book a two hour arrival window and text you when the van is twenty minutes out.

Step 2

We open the furnace closet, pull a register or two, and look at the crawlspace or attic runs first. The estimate is free, and you get one firm number for the supply and return count we actually find.

Step 3

We clean the lines, check airflow at each register, vacuum up anything we tracked in, and show you before and after photos. You pay the number we quoted, even if the crawlspace runs longer than expected.
