Is it urgent?

Can wait

Usually scheduled rather than urgent. It becomes urgent when a tenant complaint is a habitability issue, when an insurer or a lease requires documented cleaning, or after water damage in a shared system.

Two things override everything on this page. If anyone has symptoms of carbon monoxide exposure — headache, nausea or dizziness that improves outdoors — leave the building and call the gas utility or the fire service, not a duct company. And if you can smell burning while the dryer is running, unplug it and leave it.

Signs to look for

  • Tenant complaints about smell or dust that follow the system rather than one unit
  • A lease, an insurer or a franchise agreement that requires documented cleaning intervals
  • Rooftop units that have not been opened since installation
  • Water damage or a roof leak that reached the ductwork
  • A change of use or a fit-out, where the existing system is being re-purposed

How the work is done

  1. Surveying the system and agreeing scope and access before any work, since almost all of the cost is in access and hours rather than in the cleaning itself
  2. Working out of hours or in zones so the space stays usable
  3. Documenting each zone before and after, which is what the manager or insurer actually needs
  4. Handling the rooftop unit as part of the job, since it is where most of the loading is and it is the part most often left out

In California specifically

In California the ductwork is generally in attics and crawlspaces, and on slab-on-grade homes in the south often under the floor or in the ceiling plenum, which is most of why this job looks the way it does here. Wildfire smoke is the single biggest thing that makes Californians think about what their ducts are carrying. Fine particulate gets pulled into a return during a smoke event and keeps circulating long after the air outside has cleared. California is also the one state where duct leakage is routinely tested: Title 24 requires a HERS-verified duct test on most furnace or air-conditioner changeouts, so a duct problem here often surfaces as a failed test rather than as a complaint.

Before the technician arrives

Four things worth doing — and the first one is usually the thing people get wrong.

  1. Get the scope in writing by zone, with the number of hours and the access arrangements. Commercial quotes for this vary enormously and it is nearly always a difference in scope rather than in price.
  2. Find out what your insurer or lease actually requires before buying more than that.
  3. Identify who controls roof access and out-of-hours access early — it is the usual reason these jobs slip.
  4. Warn tenants in advance. Most complaints about this work are about the disruption, not the work.

How it works

Three steps, and you decide at the end of them.

  1. 1

    You call and describe the problem

    Tell us what you have noticed and where — the room, the smell, the noise, how long it has been going on. Give us your ZIP code and we will match you to a licensed company covering your area. There is no form to fill in.

  2. 2

    A local company takes it from there

    They discuss the problem with you directly, arrange a time to inspect, and agree the work and the price with you before anything starts. That conversation is between you and them.

  3. 3

    You decide whether to go ahead

    You are under no obligation. If the quote or the approach is not what you wanted, you are free to say no and call someone else.

Commercial Duct Cleaning — FAQs

Do I actually need Commercial Duct Cleaning done?

Usually scheduled rather than urgent. It becomes urgent when a tenant complaint is a habitability issue, when an insurer or a lease requires documented cleaning, or after water damage in a shared system.

What does Commercial Duct Cleaning involve?

Larger systems, rooftop units and multi-tenant buildings, where the work has to be scheduled around occupancy and documented for a building manager or an insurer.

What makes this different in California?

In California the ductwork is generally in attics and crawlspaces, and on slab-on-grade homes in the south often under the floor or in the ceiling plenum, which is most of why this job looks the way it does here. Wildfire smoke is the single biggest thing that makes Californians think about what their ducts are carrying.

Are the companies licensed and insured?

Yes. We only pass calls to licensed, insured operators working in California, and you are welcome to ask to see a license number on arrival.

What does Commercial Duct Cleaning cost?

It depends on the property, the size of the system and what the inspection finds, so we do not publish a price — a figure quoted on a web page is not one the attending company has agreed to. You get a price before any work starts.
