Post-Construction Air Duct Cleaning in Lewisville, TX
A brand-new home does not mean clean ducts. During construction, HVAC systems are test-run while drywall installation, sanding, framing, and insulation are still ongoing. Every particle in the air during that phase — drywall dust, sawdust, fiberglass insulation strands, joint compound particulate — gets pulled directly into the duct system and stays there until cleaned.
Builders in Castle Hills Northpointe and throughout Lewisville — including Toll Brothers, American Legend Homes, Britton Homes, Belclaire Homes, and Shaddock Homes — do not clean duct systems before handing over keys. This is industry standard. It is your responsibility as the new homeowner.
What’s Inside New Construction Ducts
- Drywall dust — the most common contaminant, a fine white powder that coats duct interiors and is an inhalation irritant
- Sawdust — from framing, trim work, and cabinet installation throughout the build
- Fiberglass insulation strands — microscopic fibers from blown-in and batt insulation
- Joint compound powder — from drywall finishing and sanding
- Construction adhesive and sealant off-gassing — volatile compounds that accumulate in duct system
- Concrete and masonry dust — from foundation work and tile installation
Why Castle Hills Northpointe New Builds Specifically
Castle Hills Northpointe is Lewisville’s most active new construction corridor in 2026, with 400+ new lots from builders including Toll Brothers, American Legend Homes, Britton Homes, and Belclaire Homes. Homes in the $450,000–$650,000 range with 2,500–4,000 square feet — which often means two HVAC systems, extensive flex duct runs, and a full construction season worth of debris inside those systems before the family moves in.
We have cleaned post-construction ducts in Castle Hills Northpointe builds and consistently find 1–3 pounds of construction debris inside systems that were installed just weeks before move-in.
When to Schedule Post-Construction Cleaning
The best timing is within the first 60–90 days after move-in, before you run the HVAC extensively through your first heating or cooling season. Running the system with construction debris present distributes it throughout the home — into carpets, onto furniture, and into the air you breathe.
If you have already been in your new Lewisville home for 6–12 months and haven’t cleaned the ducts, it is not too late — cleaning at any point removes the accumulated construction debris.
Post-Construction Cleaning Process
The process is identical to our standard residential cleaning: truck-mounted 12,000 CFM HEPA vacuum, negative pressure throughout the duct system, compressed air agitation at every supply and return run, all registers cleaned and reinstalled, before-and-after photo documentation. Construction debris is typically denser and more uniform than residential accumulation — it responds well to source removal and clears fully in one session.
Frequently Asked Questions
Will my builder clean the ducts before I move in?
Very rarely. In Lewisville’s active new construction market — Castle Hills Northpointe, Orchard Hill, Fox Creek — no major builder including Toll Brothers, American Legend Homes, or Britton Homes includes professional duct cleaning as standard practice. It is not covered by your builder’s warranty. It is a separate service the homeowner arranges.
What if my new home is still under warranty?
Professional duct cleaning does not void your builder warranty on the HVAC system. We drill 1-inch access holes in trunk lines for the vacuum connection — these are sealed with sheet metal plugs and do not affect system integrity. You can ask your builder in writing whether professional duct cleaning affects your warranty; the answer will be no.
How much does post-construction duct cleaning cost in Lewisville?
Pricing follows our standard residential structure: $400–$650 for a single-system new build (typical Castle Hills Northpointe single-story), $700–$1,000 for two-system homes. Written quote provided before scheduling.
