Common duct cleaning services

Air Duct Cleaning
NADCA-standard source removal of dust, debris, and allergens from supply and return ducts using mechanical agitation and continuous negative-pressure HEPA vacuuming.
Whole-home Duct Cleaning
Cleaning of the full system — all supply and return runs, main trunk lines, registers, and the air handler — not just accessible vents.
Dryer Vent Cleaning
Clearing the full dryer vent line to the exterior hood to cut fire risk (the leading cause of home dryer fires) and restore airflow.
Air Duct Sanitizing
EPA-registered antimicrobial treatment applied after cleaning to address documented microbial growth and persistent odors.
HVAC Mold Remediation
IICRC-scoped removal and treatment of mold inside ductwork and HVAC components, with encapsulation to protect cleaned surfaces.
Duct Sealing
Aeroseal aerosol or hand-applied mastic sealing of duct leaks and gaps, verified with before/after leakage measurement to cut energy waste.
Evaporator Coil Cleaning
In-place cleaning of the evaporator/air-handler coil to restore heat-transfer efficiency and airflow.
Commercial Duct Cleaning
Facility-scale duct and rooftop-unit (RTU) cleaning, including NFPA 96 kitchen grease-exhaust service for restaurants and commercial buildings.

Duct Cleaning FAQ

Do duct cleaning companies need a license?
Air-duct cleaning is generally NOT a separately state-licensed trade — most states (including Texas) do not issue a 'duct cleaning license.' The meaningful credentials are NADCA membership (the National Air Duct Cleaners Association sets the ACR cleaning standard) and, for mold scope, IICRC certification. Verify general liability insurance and NADCA membership rather than a state license.
What is NADCA certification?
NADCA (National Air Duct Cleaners Association) is the industry body whose ACR Standard defines proper source-removal cleaning — mechanical agitation plus continuous negative-pressure HEPA vacuuming. NADCA-member firms and ASCS-certified technicians are held to that standard, which is the clearest signal separating real duct cleaners from '$99 blow-and-go' operators.
How often should air ducts be cleaned?
NADCA suggests every 3–7 years for a typical home, sooner with pets, smokers, allergies, recent renovation, or visible mold. The EPA's position is that duct cleaning is warranted when there's documented mold, vermin, or heavy debris — not on a fixed schedule. Dryer vents are different: clean those annually for fire safety.
Does duct cleaning actually improve air quality?
When ducts hold heavy dust, debris, or documented mold, professional source-removal cleaning measurably reduces what recirculates through the system. It is not a cure-all — the EPA notes routine cleaning of an already-clean system shows limited benefit. The value is highest after renovation, pest activity, water intrusion, or for allergy and asthma households.
What's the difference between duct cleaning and duct sealing?
Cleaning removes contaminants from inside the ductwork. Sealing closes leaks and gaps so conditioned air stops escaping — leaky ducts waste 20–30% of heating and cooling (ENERGY STAR). They're separate services: cleaning is a few hundred dollars; Aeroseal or manual sealing runs $1,300–$3,500 and often qualifies for utility rebates.
How do I avoid duct-cleaning scams?
Watch for '$69/$99 whole-home' bait pricing, on-site upsells to 'mold treatment' with no lab test, blow-and-go visits with no source-removal vacuum, and whole-home jobs quoted under an hour (a real NADCA clean runs 2–5 hours). Insist on a written per-component scope (supply, return, trunk, air handler) before work begins.
