Marin County Air Duct Cleaning
Marin County Air Duct Cleaning
Novato is the part of Marin that actually runs air conditioning. July highs average right around eighty degrees and the town sits well outside the fog line, so systems here cycle hard through summer instead of sitting idle the way they do down near the water. That changes what gets dirty.
In a house that only heats, the ducts take most of the abuse. In a house that cools, the cooling coil and the fan do. Months of pulling damp air across a cold metal coil catches dust and holds it. A coil with a film on it cools less well, and leaves the system running longer to get the house to the same temperature. The national standard for this work covers nine parts of a system, the coil, the pan underneath it and the fan included, not just the ducts, and a job that skips them is not the standard even if the vents come out clean.
Novato houses also tend to be larger with longer runs, which is the same reason the dryer exhaust line is worth checking here. Failure to clean is the leading cause of residential dryer fires nationally, about a third of them. Call today for a free quote on air duct cleaning in Novato.
Most of the ranch-style houses built here in the fifties and sixties run their ductwork through the slab itself rather than up in the attic, which is a different animal to clean than the attic systems common in newer construction. In-slab duct runs sit below grade, and in a wet winter groundwater can seep in at the joints, which means a Novato system is more likely than most to be dealing with actual standing moisture inside the ducts rather than just dust. That combination, damp and dark, is exactly the condition source removal exists for. Newer Novato construction and additions tend to run ducts through the attic instead, so the first thing worth knowing before a quote is which kind of system is actually under your floor.
Running the air conditioner hard for four or five months does something a filter in a milder climate never has to deal with. Air gets pulled through it constantly, and once a filter loads up, air starts finding the path of least resistance around the edges of the frame instead of through the media. That bypass air carries dust straight past the filter and into the coil and ductwork, which is the opposite of what the filter is there to stop. It's a quieter problem than a dirty vent, since the house doesn't look dusty, but the buildup happens on schedule every summer whether anyone notices or not. Systems in San Rafael run into the same thing, being one of the warmer parts of the county.
