Coil Cleaning in Bodega Bay, CA

Coil cleaning in Bodega Bay

A loaded evaporator coil ices over. The ice melts, the pan overflows, and water finds drywall. Outside, a matted condenser keeps the compressor running hot for hours. That stops being a cleaning bill and becomes a replacement. Waiting is the expensive choice here.

Marine air is the local complication. Salt settles on aluminum fins and corrodes them. You see white powder and soft, crumbling edges near Doran Beach and out toward Bodega Head. Corroded fins cannot be combed straight. They tear.

Indoor coils foul from the return side. In older tract homes the return plenum and filter slot are undersized or leaking, so crawlspace and attic air bypasses the filter entirely. That debris lands on a wet coil and stays. Grass and oak pollen each spring. Fine wildfire ash after smoke events. Rodent droppings and blown insulation pulled from low crawl runs.

Check it yourself with a flashlight and a small mirror. Look at the upstream face, not the side you can see. Downstream usually looks fine while the entry face is felted shut.

Access drives the job more than dirt does. A coil buried in a tight closet or an attic air handler takes longer than the cleaning itself. Badly corroded fins are not worth cleaning, and we will say so.
