Main Trunk Line Cleaning in Alexandria, VA
The main trunk line is the large central duct that carries conditioned air from your air handler out to every room in your home. Over years of use, it collects the heaviest buildup of dust, debris, and biological matter in your entire duct system. Cleaning it isn't optional if you want the rest of your ductwork to stay clean. We remove that core accumulation so your whole system moves cleaner air.

How It Works
Our Process for Main Trunk Line Cleaning
- 1
Access and Camera Check
We locate trunk access points and run a camera through to document what's actually inside before we touch anything.
- 2
Mechanical Agitation
Rotary brushes loosen compacted debris along the full length of the trunk, including corners and transitions.
- 3
Negative Pressure Extraction
A high-powered vacuum unit at the air handler pulls all loosened material out of the trunk without spreading it into your living space.
- 4
Post-Clean Verification
We run the camera again so you can see the cleaned interior yourself before we close any access panels.
Alexandria Context
Why this matters in Alexandria
Many Alexandria homes built in the 1950s through 1980s have original galvanized steel trunk lines that have never been professionally cleaned. That accumulated load affects air quality for every room on the system.
Straight Talk
About pricing & scope
Scope depends on trunk length, the number of transitions and offsets, and how much material has accumulated over time. Systems in older homes with original ductwork typically take longer than newer installations.
