Why San Marino homes need air duct cleaning
San Marino ducts work all year, carrying cooled air through the summer and forced-air heat through the winter. Pets, a move into a new home and a recent remodel are when dust and debris build up enough to matter. 94% of homes here were built before 1980, so many duct runs are decades old. About 14% of residents moved into their home in the past year, and a new home is a common time to have the ducts cleaned. Los Angeles County logged 98 days of air unhealthy for sensitive groups or worse in 2025. Searches for duct cleaning in California peak in July and August.

Air duct cleaning questions San Marino homeowners ask
How do I choose an air duct cleaning company in San Marino?
- A written, itemized quote before work starts: what's included, any access fees, and no extras without your OK.
- The scope covers the supply and return ducts, the blower and the coils, not just the vent covers.
- Ask how debris is collected (negative-pressure collection) and how your ducts and home are protected.
- Before-and-after photos of your own system.
- Mold claims come with evidence, such as a sample or a test, before any chemical treatment.
- Walk away from bait "whole-house" prices.
- For repair or sealing work, check the contractor's California license with California's Contractors State License Board.
