“Duct inspection” can sound vague if you’ve never had one done. In practice, it’s a structured, step-by-step process using a small video camera to actually see inside your ductwork — not just guess based on what’s visible at the vent cover. Here’s what happens from start to finish.
Step 1: A Walkthrough of Your System
Before any camera goes into a duct, your technician walks the accessible parts of your system — the furnace or air handler, visible trunk lines, and vent covers — to understand the layout and note anything unusual up front.
Step 2: Camera Inspection of the Duct Interior
A flexible camera is fed through supply and return runs to capture footage of the actual interior surfaces. This is how we find things a flashlight and mirror simply can’t reach, including buildup deep inside long runs.
Step 3: Checking for Dust & Debris Buildup
The camera footage shows exactly how much dust, dander, and debris has accumulated along the duct walls — giving you real evidence instead of a guess about whether cleaning is actually needed.
Step 4: Checking for Mold or Moisture
Discoloration, staining, or visible mold growth on interior duct surfaces gets flagged and documented. If anything looks concerning, we’ll point you to a more thorough air quality and mold assessment rather than guessing.
Step 5: Checking for Pests or Contamination
Droppings, nesting material, or insect activity inside ductwork is more common than most homeowners expect, especially in older homes or after a period of vacancy. The camera makes this easy to confirm rather than assume.
Step 6: Checking Seals, Connections & Damage
Disconnected joints, torn flex duct, and gaps at connections all show up clearly on camera. These are the kinds of issues that waste conditioned air and pull in attic or crawlspace dust even if the ducts themselves are clean.
- Dust and debris buildup along duct interior surfaces
- Mold, staining, or signs of trapped moisture
- Pest droppings, nesting, or contamination
- Disconnected joints, tears, or damaged sections
Pro TipAsk your technician to show you the footage in real time. A good inspection isn’t just a verbal summary — you should be able to see what they see before deciding on next steps.
Step 7: A Written Summary of Findings
After the walkthrough and camera inspection, you get a plain-language summary of what was found — buildup levels, any damage or contamination, and a recommendation on whether a full whole-home cleaning is actually needed right now or can wait.
How Long Does It Take?
A standard inspection typically takes 30 to 45 minutes depending on your home’s size and duct layout. It’s included free with every appointment, whether or not you move forward with a cleaning.
