Signs you need new air ducts.

Check for these. If you see even one, book a free inspection and we will look at it with you.

  • Ducts with a torn or missing outer jacket, and insulation showing.
  • Ducts that sag, kink or are flattened.
  • A duct that has come loose and blows air into the attic or crawl space.
  • Chew holes or droppings on or inside the ducts.
  • Dust blowing out of the vents when the system starts.
  • No airflow through one vent or a few vents. It is worth having it checked.
  • The attic or crawl space is being cleaned, and the old ducts are damaged.

Questions, answered.

Are you licensed for duct work?

Yes. California contractor license #1149346 includes C-20 HVAC.

Can you replace ducts and clean the crawl space in one job?

Yes. Many homeowners do both together. The old ducts and the debris come out, the space is cleaned, and the new ducts go in. Booking both counts as multiple services: 10% off (one discount per job).

How is it priced?

We price it after the free inspection, and you get a written quote the same day as the free inspection. 10% off when you add it to other services, or $300 off any job over $2,000 (one discount per job).

How long does duct replacement take?

It is a one-day job.

Do you take the old ducts away?

Yes. The old, damaged ducts are removed and taken away with us.

How are the new ducts installed?

They are run and supported to fit the height and layout of your attic or crawl space.

Can you add new insulation in the same visit?

Yes. New ducts can be done together with new insulation or crawl space cleaning. Two or more services get 10% off (one discount per job).

How do you protect my home on job day?

The crew covers the path from your front door to the work areas with drop cloths or plastic sheeting: the floors, and some walls where needed. Old material and debris go out with us.

Do I need to be home on the job day?

Yes, please be home. It also helps to clear the path to the work areas of breakable items, like pictures and vases.
