Air Duct Sanitization Service San Antonio, TX

Professional Air Duct Sanitization Services in San Antonio, TX

Property managers want vacant units to smell fresh before new tenants arrive. Our crew handles air duct sanitization for homes and commercial properties. A camera inspection comes first, so we know which duct runs need the most attention. We explain the product we use and how long to wait before using the space. We treat each section with a sanitizer designed for use in air ducts. Each duct run is treated so no section is left out. After sanitizing, we check the ducts to confirm every section was treated. The specific air duct sanitization services we offer are listed below.

Whole House Duct Sanitization in San Antonio

A sanitizer only reaches microbes on clean surfaces, so treating dusty ducts leaves most contamination untouched under the debris. Our team cleans every supply and return run with rotary brushes and HEPA negative air extraction before any product goes in. Once the system is clean, we fog an EPA-registered antimicrobial through the ducts from the main trunk so the mist reaches each branch. Registers and grilles get wiped with the same product, and the return plenum gets treated by hand. The system stays off for the dwell time listed on the label, then runs with windows open to ventilate the home. Every room receives air from a cleaned and treated duct system. Air balancing service can also help adjust airflow throughout the system so treated air reaches each room more evenly.

HVAC Duct Sanitization in San Antonio

The air handler holds the wettest surfaces in the system, and growth there spreads to every duct it feeds. San Antonio Air Duct Pro shuts off power, opens the air handler cabinet, and cleans the blower wheel, plenum walls, and cabinet interior. The coil and drain pan get cleaned with a coil cleaner, then treated with an EPA-registered product labeled for those surfaces. We spray the supply and return plenums where they connect to the cabinet, since condensation collects there first. The condensate line gets flushed so standing water stops feeding new growth. A new filter goes in before the system restarts. The central unit stops sending musty air into the ducts, and the coil stays cleaner between services.

Duct Disinfecting Service in San Antonio

After an illness in the home, a new move-in, or a renovation, many homeowners want the ducts disinfected along with the rest of the house. Our pros clean the full duct system first, then apply an EPA-registered disinfectant labeled for use in HVAC duct systems. The product goes on with an electrostatic sprayer or ULV fogger that coats duct walls, register boots, and grilles evenly. We follow the label for contact time, then ventilate the home before the system returns to normal use. The service report lists the product name and EPA registration number for your records. You get a cleaned and disinfected system and a clear record of what went into your ducts. HVAC duct cleaning can also help remove accumulated dust and debris before disinfection, giving the treatment a cleaner surface to work on.

Antimicrobial Mold Treatment in San Antonio

Humid air lets mold grow on duct liners, boots, and coils, and the first sign is often a musty smell when the AC starts. Our crew maps the growth with a camera, then removes it from hard metal surfaces with brushing and HEPA vacuuming. Porous duct liner or duct board with heavy growth gets flagged for replacement, since cleaning cannot fully remove growth from fibrous material. After removal, we apply an EPA-registered antimicrobial to the cleaned areas to slow regrowth. When growth covers a large area, we recommend testing by a licensed mold assessor before work begins. Musty odors fade, and the treated sections stay cleaner once the moisture source gets fixed.

Evaporator Coil Sanitizing in San Antonio

The evaporator coil stays cold and wet while the AC runs, which makes it a common place for slime and mold to form. We remove the coil access panel and inspect the fins and drain pan for buildup and standing water. A foaming coil cleaner lifts dirt from deep in the fins, and a low-pressure rinse carries it into the drain pan. The cleaned coil and pan then get treated with an EPA-registered coil sanitizer. We flush the condensate line and test the float switch so water drains without backing up. The coil transfers heat better, and the musty smell that starts with each cycle goes away. Negative air pressure duct cleaning can also help remove dust and debris from ductwork by keeping the system under controlled suction during cleaning.

Duct Deodorizing and Odor Removal in San Antonio

Cooking, smoke, pets, and past water leaks leave odors that soak into dust and duct surfaces and return each time the system runs. Our team traces the odor with a camera inspection and a walk through the rooms where it smells strongest. The ducts get cleaned to remove the dust and residue holding the smell. We then apply an EPA-registered deodorizer labeled for HVAC use, focusing on the return side where odors enter the system. Registers and grilles get washed in a degreasing solution before reinstallation. When the source sits outside the ducts, such as a dead animal in a wall, the technician points you to it. The odor stops returning with each cycle, and the home smells fresh when the AC runs.

Pest Contamination Sanitization in San Antonio

Rodents and roaches leave droppings, urine, and nesting material inside ducts, and the system can carry particles from that waste into living areas. San Antonio Air Duct Pro schedules sanitization after pest control has cleared the infestation and sealed the entry points. Technicians wear respirators and disposable suits, then remove nests and droppings with HEPA vacuums instead of dry sweeping. Damaged flex runs with heavy contamination get replaced instead of cleaned. The remaining ducts get cleaned and treated with an EPA-registered disinfectant labeled for HVAC use. A follow-up camera check confirms no droppings or nesting material remain. Your system stops carrying pest waste into your rooms, and the lingering odor disappears. New construction duct cleaning can also help remove construction dust, drywall debris, and other particles left inside ductwork after a new build.

Duct Liner Encapsulation in San Antonio

Fiberglass duct liners and duct board shed fibers and trap dust as they age, and their rough surfaces resist normal cleaning. Our pros clean the lined sections gently with soft brushes and HEPA extraction to avoid tearing the surface. Your technician confirms the coating is compatible with your liner before application. We then spray an encapsulant coating approved for HVAC duct interiors that seals loose fibers and creates a smoother surface. Sections with heavy growth or crumbling liner get replaced instead of coated. The coating cures before the system restarts, and the crew ventilates the home. Lined ducts stop shedding fibers into the air, and the smoother surface collects less dust.
