For Homeowners
Your house has lungs.
Protect them before
the walls close.
Your ducts sit wide open through months of construction. Tempvent keeps the dust, paint, and debris out — so your family breathes clean from day one.
During the build
Your HVAC never stops running.
Drywall dust. Paint. Insulation. It all gets pulled into your ducts — every day, for months.
Your ducts are a vacuum with no bag.
Whatever the jobsite kicks into the air during construction, the duct system quietly keeps.
The misconception
The cleanup you’re counting on isn’t in the contract.
Most builders don’t include a real duct cleaning — and even one that happens can’t reach the fine dust already in the liner.
“My builder will clean the ducts before we move in.”
Reality: usually it’s not in the contract — and a cleaning can’t recover what’s already embedded in the duct liner.
What happens next
Debris in ducts is what mold grows on.
Wood dust, drywall compound, and insulation fibers plus a little seasonal moisture is everything mold needs to start.
You usually don’t notice for a season or two — dark spots at the registers, a musty smell, a family that’s sick more than it should be in a brand-new house.
Stop it before the floors go in — and the keys change hands.
Prevention during the build is the only thing that keeps it out for good. After the walls close, it’s remediation.
