A duct camera inspection puts a small camera on a flexible cable inside your ducts, so you can see the real condition instead of guessing. It can show dust build-up, debris, moisture stains, damaged insulation, and signs of pests. It cannot confirm mold by itself. The EPA says a thorough visual inspection is the best way to verify the cleanliness of a system, and that some providers use remote photography to document conditions inside ducts.
A camera inspection looks inside hidden ducts
Most of your duct system is hidden in the attic, in walls, or above the ceiling. A technician opens small access points and feeds a camera through the supply and return ducts. The camera shows a live picture and can save photos. You see the same thing the technician sees.
Not every system can take a camera. Some registers, tight flex runs, and sealed sections are too small or closed off. Wherever your system allows it, we start with a camera look inside, and we show you what we see.
NADCA, the trade association for duct cleaners, says inspections should happen before and after a cleaning project, and that inspections are done to determine the need for cleaning.
What can the camera show?
| What you may see | What it may mean | A sensible next step |
|---|---|---|
| A thin layer of dust | Normal. The EPA says there is no evidence a light amount of household dust in ducts is a health risk. | Usually no cleaning needed. Change your filter. |
| Thick debris or build-up | Particulate has built up, or the system is carrying debris into rooms. | Cleaning may be reasonable. |
| Dark or wet stains near the coil or pan | A moisture problem. The EPA calls condensation near cooling coils a major factor. | Fix the water source first. |
| Wet, torn, or damaged insulation or liner | The EPA says wet or moldy duct insulation cannot be cleaned effectively and should be replaced. | Repair or replace. |
| Droppings, nesting, or chewed material | Pests may have entered the ducts. | Remove the cause, then clean if needed. |
| Fine construction dust | Dust from a remodel can end up in the system. NADCA lists construction debris as a reason to clean. | Cleaning may be reasonable. |
| A loose or crushed duct section | An air leak or damage. | Repair, since cleaning will not fix it. |
The limits of a camera inspection
A camera shows surfaces. It has limits:
- It cannot confirm mold. Many substances look like mold. The EPA says only an expert can make a positive determination, and it may need laboratory analysis. The EPA also advises asking the provider to show you any mold they say exists.
- It cannot see everything. The EPA notes that many parts of a system may not be accessible for a visible inspection.
- It does not test for microbes. NADCA’s cleanliness check looks for particulate. It does not determine microbial contamination.
Steps in a camera inspection
- The technician opens access points in the ducts and at the air handler. The EPA says a provider should open access ports to allow the whole system to be cleaned and inspected.
- Wherever the system allows it, the camera goes through the supply and return runs and looks at the coil area.
- You see the live view or the photos and ask questions.
- The technician checks for materials that need special handling. The EPA says a provider should inspect for asbestos-containing materials before cleaning, because they require specially trained contractors.
- The technician confirms the price before any work starts, and you approve it. The EPA advises getting a written scope and total cost before work begins.
- If you approve cleaning, we show you the result afterward, on camera where the system allows it, with photos whenever possible.
Using the photos to decide
Look at the pictures and ask these questions:
- Is the debris heavy, or is it a thin film?
- Is it dry dust, or are there signs of moisture?
- Is it the same in several places, or in one spot only?
- What would change if we did nothing?
- Does the camera show the same condition near the air handler and at the far end of the ducts?
- Can the technician point to the spot on the photo and explain what it is?
Sometimes the answer is that cleaning is not needed. We would rather tell you that than sell a job you do not need. For more on timing, see our guide on how often to clean air ducts in South Florida.
Camera inspections at Blue Pelican
- A look first. Wherever your system allows it, we start with a camera look inside, and we show you what we see, with photos whenever possible.
- A free check. Every visit starts with a free Whole-Home Air & Attic Check, and nothing is added without your approval.
- What we remove. Dust, allergens, pet hair, debris and bacteria that have settled in your ducts.
- How we clean. Rotary brushes loosen the buildup, and a HEPA-filtered negative-pressure vacuum keeps the ducts under suction and removes it from your home. Debris is collected through HEPA-filtered equipment, never blown into your living space. We clean every duct and vent in your home, then finish with an airflow and system check.
- Botanical finish. We finish with a botanical product made with thyme oil, with no harsh chemicals.
- Our own team. Our technicians are our own employees, never subcontractors.
