Air Duct Cleaning in
Castle Hills, Lewisville TX
One of the largest master-planned communities in North Texas — 2,900+ acres, 4,000+ homes, and Northpointe’s active new construction corridor in 2026. Each era of Castle Hills has its own duct cleaning reality.
Castle Hills Northpointe — New Construction in 2026
The most active new construction corridor in Lewisville. Builders don’t clean ducts before handover. Before photos tell the full story.
HVAC systems in new construction are test-run during active drywall work, sanding, framing, and insulation installation. Every fine particle in the air during those phases — drywall dust, fiberglass strands, sawdust, joint compound — goes directly into the duct system. Builders including Toll Brothers, American Legend Homes, Britton Homes, Belclaire Homes, and Shaddock Homes do not clean duct systems before key handover.
We consistently extract 1–3 pounds of fine construction debris from Northpointe builds that are 30–90 days old. Schedule within the first 60–90 days of move-in — before you run the system through your first full Lewisville summer.
Established Castle Hills Phases
The established phases built in the late 1990s through 2000s have flex duct systems now 20–30 years old. Common issues: sagging flex duct at low points where debris pools, heavy cedar pollen accumulation in return ducts from 5–10 cedar seasons, and occasionally disconnected duct segments at collar connections that have separated over time.
Why Castle Hills Costs More to Clean
Most Castle Hills homes above 2,500 sq ft are two-story with two HVAC systems. This is the single most important factor for homeowners comparing quotes.
Two Systems = Two Separate Jobs
Two systems means two duct networks, two trunk line connections to the vacuum, and roughly double the individual duct runs to agitate. A 3,000 sq ft Castle Hills two-story takes 5–7 hours. A 1,800 sq ft single-story takes 3–4 hours. The price difference reflects actual labour time.
Cedar Pollen Accumulation
Castle Hills sits squarely in the Ashe juniper cedar belt. December through February, cedar pollen passes through MERV-8 filters and deposits in return ducts on every heating cycle. Two HVAC systems running frequently during January cold snaps cycles a substantial air volume — and substantial pollen accumulation rate.
Confirm Your System Count
Before getting quotes, confirm whether your home has one or two systems. Check your thermostats — two thermostats controlling separate zones indicates two systems. You can also check your attic for two air handler units. Knowing this before calling gives you accurate comparisons.

“Moved into our Toll Brothers home in Northpointe in February. They showed us the before photos — white drywall dust coating throughout the trunk line. We had been running the system for six weeks before we knew.”
“Our builder did a punch list clean-out before closing. We assumed that meant the ducts were clean. It did not. They extracted a small bucket of construction material from our 90-day-old home. Eye-opening.”
