Coil Cleaning in San Mateo, CA
Call (415) 251-5692
What a dirty coil actually costs you
A matted evaporator face chokes return airflow first. Suction pressure falls. The coil frosts, then ices solid. Melt water overruns the drain pan edge. On a horizontal attic unit in a slab tract home, that lands on bedroom drywall. Flooded compressors fail outright. Cleaning is the cheap end of that sequence.
Most fouled coils here trace to the return side, not the air outside. Filter slots on older furnaces are often undersized or missing a gasket. Unfiltered air slips around the frame and loads the coil directly. Panned floor-joist and wall-stud returns pull crawlspace dust with no filtration at all. When the furnace sits in the garage, the return plenum grabs garage air too.
The local dust mix is unkind. Fine salt and marine aerosol corrode condenser fins toward the baylands. Wildfire soot in late summer is fine and sticky. Tree and grass pollen mats the entry rows March through June.
Both faces get inspected with mirror and light. Low pressure rinse only, never a pressure wand on thin aluminum. Fins get combed where bent. Pan and trap cleared. Blower wheel cleaned the same visit, since a loaded wheel re-soils the coil fast.
If fins are eaten through by corrosion or the coil leaks, cleaning fixes nothing. We say so instead of washing it.
What Happens After You Call Us
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.
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.
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.
