How We Clean Your Lewisville Home’s Air Ducts
Transparency is what separates legitimate duct cleaning from the $49 operations. Here is exactly what happens on a real cleaning job from the moment the truck arrives to the moment we leave — so you can verify the process is being followed.
Step by Step — What Happens on Every Job
Everything described here applies to every residential job — from a 1,400 sq ft Old Town cottage to a 3,800 sq ft Castle Hills two-story. Same equipment. Same methodology. Same documentation.
Written Quote First
Before any appointment is booked, you receive a written price for your home’s size, number of systems, and duct configuration. That price is confirmed and does not change on arrival. No on-site variables.
Arrival & Walkthrough
Two technicians arrive. Shoe covers on before entry. Drop cloths down. We walk every room, locate every supply register and return grille, inspect the air handler, and review scope with you. If anything changes the written quote, you hear about it before we start.
Negative Pressure Setup
The 12,000 CFM truck-mounted HEPA vacuum connects to your main trunk line via an 8-inch access hole. Full negative pressure throughout the entire duct network. Every run pulling toward the vacuum. Nothing gets blown around your home.
Individual Duct Agitation
Compressed air at 250 PSI through air rods, octopus whips, and forward/reverse heads — every supply and return duct run individually. Farthest registers first, working toward the trunk. Every run. Not just accessible ones near the registers.
Trunk Line & Air Handler
Main supply and return trunk lines cleared. Blower compartment and evaporator coil area cleaned and inspected. The coil is the primary mold growth site in Lake Lewisville area homes — mold documented with photos if found.
Registers, Sealing & Report
All registers removed, washed, reinstalled. All access holes sealed permanently with sheet metal and metal tape. Before-and-after photos. Written service report delivered before we leave. You see exactly what was there and what’s gone.
Job Duration by Lewisville Home Type
| Home Type | Systems | Typical Vents | Duration |
|---|---|---|---|
| Under 1,500 sq ft, single-story | 1 | 8–12 | 2.5–3.5 hours |
| 1,500–2,500 sq ft (typical Lewisville home) | 1 | 12–18 | 3–5 hours |
| 2,500–3,500 sq ft, two-story | 2 | 18–26 | 5–7 hours |
| 3,500+ sq ft, two-story | 2 | 24–36 | 6–8 hours |
| Pre-1990 Old Town / Lewisville Valley (never cleaned) | 1 | 10–16 | 4–6 hours |
If They Say Under an Hour — It’s Not Source Removal
If any company tells you they can clean a full home in under an hour, they are not doing source removal. Physically impossible at any vent count with legitimate equipment. The 3–7 hour range isn’t padding — it’s the time required to agitate every individual duct run correctly.
