Every time your system runs, the whole house breathes through its ducts. Air is pulled in through the returns, crosses the blower and coil, and goes back out through the supply registers, and whatever it carries tends to settle somewhere along that loop. For many Daly City homeowners, that is just a light film of dust and pet dander. For others, it is drywall dust from a remodel, construction debris that has sat in the trunk lines since the house was built, signs of rodents in crawlspace runs, or a musty odor that shows up at every startup. Either way, the buildup costs you twice: worse air to breathe, and higher static pressure with a coated blower wheel and coil, so the system works harder and moves less.
Our two most requested repairs are AC Repair and Furnace Repair. Start there if your system isn't running right.
Warning Signs for Air Duct Cleaning
Catching these issues early helps you avoid costly problems. Here are the most common indicators that it's time to call a professional:
- Moving into a home where nobody knows when the ducts were last touched
- Air filters that clog with dark debris long before they should
- Air that smells damp or musty whenever the blower runs
- Dark dust shadows forming around supply vents on the ceiling
- Allergy or dust complaints that get worse indoors, not better
- Recent sanding, demolition, or drywall work with open registers
- A puff of dust from the registers each time the system kicks on
- Signs of rodents or insects in or around the duct runs
