How often should I have my air ducts cleaned in Baytown?
The EPA and NADCA recommend air duct cleaning every 3–5 years for most homes. In Baytown, where humidity, pollen, and allergen levels are elevated, we recommend every 2–3 years — or annually for homes with pets, young children, allergy sufferers, or older duct systems.
What are the signs my air ducts need cleaning?
Visible dust coming from vents when the system runs, musty or stale odors from the HVAC system, increased allergy or asthma symptoms indoors, excessive dust settling on furniture shortly after cleaning, or visible mold growth near vents or on the air handler. Any of these indicate it’s time for professional cleaning.
What is the NADCA source removal method?
Source removal is the NADCA-standard cleaning methodology that uses negative pressure (vacuum containment), rotary brush agitation, and HEPA-filtered extraction to physically remove contamination from duct surfaces. It’s the only method that actually removes material — not just redistributes it. JY Air Duct Cleaning uses source removal on every job.
How long does air duct cleaning take?
A standard residential system takes 2–4 hours depending on system size, number of vents, and level of contamination. Larger homes with multiple HVAC systems may take longer. We always provide a time estimate before starting and keep you informed throughout the process.
Is JY Air Duct Cleaning certified to service air ducts in Harris County?
Yes. JY Air Duct Cleaning has held NADCA certification since 2017 and is fully licensed and insured ($1M liability) throughout Harris County and the greater Houston metro area. Our technicians are trained in NADCA source removal methodology for both residential and commercial HVAC systems.

What Our Crews Look For — Mechanical Conflict First
Dust buildup in Baytown homes is downstream of a mechanical conflict. Three environmental factors converge here: (1) Galveston Bay salt-air at 70-85% humidity year-round, (2) refinery corridor particulates from ExxonMobil and Chevron operations along TX-146 that settle into return trunks faster than typical residential dust, and (3) legacy moisture damage from Hurricane Harvey (2017) that we still find as biofilm on evaporator coils. Most homes we visit show one of four conflicts: blower wheel imbalance (you hear it before you see it), flex-duct collapse at supply boots (which spikes static pressure and chokes airflow), biofilm on the evaporator coil (Gulf humidity feeds it), or a compromised plenum box seal pulling attic dust into the return. We confirm with a borescope and a Delta-T measurement before quoting. Marsh-adjacent homes near Turtle Bayou and Cape Royale also see rodent intrusion into attic ducts — we check for droppings and nesting during every borescope inspection.
Our NADCA ACR Standard Process
Every job follows the NADCA Assessment, Cleaning & Restoration (ACR) Standard: pre-inspection with Delta-T airflow measurement, HEPA-filtered negative-air containment on the trunk line, Rotobrush rotary agitation supply-side and return-side, hand-cleaning of every supply boot and return register, air-handler cabinet cleaning (blower wheel, evaporator coil face, drain pan), optional EPA-registered antimicrobial fog, and post-clean Delta-T + static-pressure remeasurement. Written report on before/after airflow. If ducts don’t need source-removal cleaning, we’ll recommend a MERV 11-13 filter upgrade instead — we diagnose, we don’t upsell.
