Commercial & NYC School HVAC Duct Cleaning

Who This Service Is For

This page is for the people responsible for a building's air systems and the paperwork behind them:

• NYC public school custodial engineers, principals, and SCA project teams.
• Facility and property managers for office, retail, and mixed-use buildings in the five boroughs and on Long Island.
• Healthcare, senior living, and laboratory facilities that inspect on the shortest cycles and need documented results.
• Colleges, universities, private schools, and athletic complexes.
• General contractors and mechanical contractors who need a certified duct cleaning subcontractor, including for M/WBE participation goals on public projects.

Credentials That Matter for Procurement

We publish our credentials so you can check them rather than take our word. Each one answers a specific question a buyer, agency, or general contractor has to answer before awarding duct cleaning work:

• NADCA member company: the work follows a published standard (ACR) with defined inspection, cleaning, and verification steps, so your spec can reference it and your inspector can check against it.
• ASCS-certified technicians: the people on site hold an individual, examination-based certification maintained with continuing education, not just a company logo.
• Certified NYC School Construction Authority (SCA) contractor: we meet the SCA's prequalification requirements to perform air duct cleaning in New York City public school buildings.
• Women-Owned Business Enterprise (WBE), certified by New York State and New York City: our participation counts toward M/WBE utilization goals on public contracts, which matters to prime contractors and agencies scoring bids.
• OSHA-trained crews and NYS DOL mold licensing, detailed on the About page, for facilities where safety and remediation credentials are reviewed before access is granted.

NYC School Construction Authority (SCA) and School Projects

School HVAC duct cleaning is its own discipline. Buildings are occupied ten months a year, the work has to land inside summer recess or a holiday break, and the documentation is reviewed by custodial engineers, principals, district facilities staff, and, for New York City public schools, the School Construction Authority. SaniTech is a certified NYC SCA contractor and has cleaned HVAC systems for New York City public schools on summer-break timelines, as well as for Long Island districts, colleges, and athletic facilities.

A typical school engagement runs in three stages. First, an inspection during the school year documents every air handler and representative ductwork so the scope, access needs, and any moisture or pest issues are known before bids are due. Second, the cleaning itself is sequenced building by building and wing by wing during recess, with multiple crews running in parallel and any summer-program spaces isolated with containment. Third, closeout: before-and-after photographs by unit, a component-by-component report, and paperwork formatted for the district or agency file.

• Unit ventilators, rooftop units, and central air handlers cleaned as part of the same scope, including coils and drain pans.
• Gymnasiums, locker rooms, cafeterias, and science wings treated as separate zones with their own documentation.
• Scheduling built around summer school, athletics, and construction trades already in the building.
• Optional Surface Antimicrobial Solutions (SAS) for locker rooms and wrestling or training rooms in the same visit.

Occupied Buildings and After-Hours Scheduling

Most commercial duct cleaning in New York City and on Long Island happens while the building is in use, so the plan has to protect occupants and keep the systems that serve them running. Work is sequenced by floor, wing, or air handler; the zone being cleaned is isolated with containment and negative air so dust never migrates to occupied areas; and systems are returned to service before each shift. Nights, weekends, holiday breaks, and planned shutdowns are the normal windows. Healthcare, laboratory, and food service spaces get additional controls agreed with your facilities team in advance, and every crew is OSHA-trained for the site.
