Frequently Asked Questions

How often should I clean my air ducts?

The EPA and NADCA recommend every 3–5 years for most homes. You may need it sooner if you have pets, allergies, recent renovations, or visible dust coming from vents.

How often should I clean my dryer vent?

At least once a year for a typical household. If you do heavy laundry or have a long vent run, consider every 6 months. A clogged dryer vent is one of the leading causes of house fires.

How often should I have my chimney swept?

The National Fire Protection Association recommends an inspection and cleaning at least once a year, regardless of how much you use your fireplace.

How long does each service take?

Air duct cleaning typically takes 2–4 hours depending on the size of your home. Dryer vent cleaning is usually 45–60 minutes. A chimney sweep with inspection takes about 1 hour.

Do I need to be home during the cleaning?

Yes, we ask that an adult be present during the service so our technician can walk you through the work and answer any questions before and after.

Will air duct cleaning make a mess in my home?

No. We use negative air pressure equipment that captures all debris inside the duct system before it can enter your living space. We also protect your floors and vents throughout the job.

What is creosote and why is it dangerous?

Creosote is a tar-like residue that builds up inside your chimney flue when wood burns. It is highly flammable and is the leading cause of chimney fires. Regular sweeping removes it before it becomes a hazard.

How do I know if my dryer vent needs cleaning?

Common signs include clothes taking more than one cycle to dry, the dryer feeling hot to the touch, a burning smell during operation, or the exterior vent flap not opening when the dryer runs.
