HVAC duct cleaning
We'll tell you if your ducts don't need cleaning.
- Honest assessment first
- Supply, returns and air handler
- Cause fixed so it doesn't come back
Air duct cleaning in San Diego is easy to sell and hard for a homeowner to check, so we start with the EPA's position: ducts should be cleaned as needed, not on a routine schedule, and there's no proof that cleaning them heads off health problems. The cases where it makes sense are specific: substantial visible mold inside the system, rodents or insects, or ducts so clogged that dust blows out of the registers.
If yours qualify, we clean the whole system, not just the duct runs. The EPA notes that cleaning only part of it can recontaminate the rest. That means supply and return ducts, registers, grilles and diffusers, the blower and its housing, and the air handler. If they don't, we'll tell you, and suggest filter and moisture fixes instead. Pair it with dryer vent cleaning to cover both airflow systems in one visit.
Dust blowing out of the vents?
Change the filter first. If it keeps happening, send us a request and we'll take a look.
What a full duct cleaning includes
Following the EPA's description of a thorough job, every component that air passes through gets cleaned.
Supply & return ducts
Debris loosened and pulled out under negative pressure so it's captured rather than blown into the house.
Registers, grilles & diffusers
Removed where possible, cleaned and refitted.
Blower & air handler
The fan, motor housing and air handler cabinet cleaned, where much of the dirt collects.
Coil & drain pan check
The cooling coil and condensate pan inspected, since moisture there is a common source of mold.
When cleaning makes sense, and when it doesn't
Worth doing
Visible mold growth inside ducts or on components, signs of rodents or insects, or ducts clogged enough that particles come out of the supply registers.
Usually not needed
A little dust on register covers, or simply because it's been a few years. A better filter, changed regularly, does more for those.
Signs your ducts may need cleaning
These are worth a look:
- Dust puffs when the system startsParticles coming out of the supply registers.
- Musty smell from the ventsPossible moisture or mold inside the system.
- Droppings or nesting materialPests have been in the ductwork.
- After a remodelConstruction dust gets drawn in if registers weren't sealed off.
- After Santa Ana dust eventsDry winds can push extra dust in through gaps and returns.
Safety first. If you see mold inside your ducts or on HVAC parts, have it confirmed and fix the moisture source first; the EPA notes wet or moldy fiberglass insulation should be replaced, not cleaned. Avoid any provider that claims EPA certification. The EPA doesn't certify duct cleaners.
