Question 1

What equipment does the Duct Doctor use?

Accepted Answer

We run a patented truck-mounted vacuum that pulls roughly 10,000 cubic feet per minute of suction, paired with 150 to 200 psi compressed-air tools on hollow poles. That combination is 5 to 20 times more powerful than the rotary-brush and shop-vac setups most companies use, which is what lets us actually remove debris instead of just stirring it up.

Question 2

How can duct cleaning be done correctly?

Accepted Answer

The only method that works is source removal. We put the system under strong negative pressure and agitate the full length of every supply and return duct so the debris is pulled back to the truck's filtered collection unit, not blown around your home. If a company is not using true source removal, they are moving dust, not removing it.

Question 3

How often should air duct cleaning be done?

Accepted Answer

For most homes, every three to five years is the right interval. You will want it sooner if you have pets, allergy or asthma sufferers in the house, recent renovation or construction, or if anyone smokes indoors.

Question 4

How long does duct cleaning take?

Accepted Answer

A typical residential job runs two to four hours depending on the size of the home, how many vents you have, and the condition of the system. We do not rush it, because a proper source-removal cleaning takes time.

Question 5

How much does duct cleaning cost?

Accepted Answer

Price depends on the size of your home and the number of vents and systems involved. We give you a clear, honest quote up front after we understand the specifics of your home, with no surprise add-ons the day of service.

Question 6

How frequently should dryer vents be cleaned?

Accepted Answer

At least once a year. Lint builds up faster than people expect, and a clogged dryer vent both wastes energy and is one of the leading causes of house fires, so annual cleaning is a real safety issue, not just efficiency.

Question 7

What are the benefits of air duct cleaning?

Accepted Answer

Cleaner air duct systems mean fewer airborne dust and allergens, a HVAC system that runs more efficiently, and fewer odors circulating through the home. If you are dusting constantly or your allergies flare indoors, your ductwork is often the reason.

Question 8

When is air duct cleaning necessary?

Accepted Answer

It is warranted when there is visible mold in the ductwork, heavy dust or debris, signs of rodents or insects, or after any major renovation. I have opened return plenums packed with inches of drywall dust after a remodel that the homeowner had no idea was there.

Question 9

How is Duct Doctor unique among duct cleaning providers?

Accepted Answer

We do one thing and we do it better than anyone: true source-removal duct cleaning with professional truck-mounted equipment and NADCA-trained technicians. We are not a carpet or blow-and-go outfit adding duct cleaning as a side service.

Question 10

Is duct sanitation safe?

Accepted Answer

Yes. When sanitation is requested we use EPA-registered products applied exactly according to label directions, so they are safe for your family and pets once the system is back in service.

Question 11

What is the debris in my ducts made of?

Accepted Answer

It is usually a mix of household dust, dead skin cells, pet dander, pollen, insulation particles, and construction or drywall dust that builds up over years. In older or neglected systems we also find mold and evidence of pests.

Question 12

Why is duct cleaning necessary?

Accepted Answer

Every time your system runs, whatever is sitting in the ductwork gets circulated through the house. Cleaning removes that buildup at the source, which improves the air you breathe and helps the system run more efficiently.

Question 13

Will duct cleaning make my home dirty on the day of service?

Accepted Answer

No. Our sealed, negative-pressure truck system captures the debris inside the equipment, and our uniformed technicians protect your floors and furnishings while they work. You should end the day with cleaner air and a clean home.
