An HVAC system is only as clean as the ductwork moving the air. Over time, supply and return ducts accumulate construction dust, skin cells, pollen, mold spores, and microbial biofilm on coils — degrading indoor air quality, driving up fan energy, and fouling the coil surfaces the building relies on for heat transfer. Cismycro Environmental provides commercial HVAC duct cleaning for NYC office buildings, residential towers, hospitals, schools, and industrial facilities. We clean the entire system — not just the registers you can see.
What's Included
- Supply, return, and exhaust duct interior cleaning
- Air handler unit (AHU) housing, blower, and coil cleaning
- Plenum, mixing box, and damper cleaning
- VAV box cleaning
- Diffuser, grille, and register cleaning (Anemostat, Titus, Krueger, Price)
- Fresh air intake and louver cleaning
- Coil sanitizing with EPA-registered agents (optional)
- Pre- and post-cleaning photo documentation and written report
Why HVAC Duct Cleaning Matters
- Indoor air quality. Every breath tenants take passes through your ducts. Dust, biofilm, and microbial growth in the system show up as IAQ complaints, absenteeism, and asthma flare-ups.
- Energy efficiency. A fouled coil can increase fan energy use by 10–30%. Clean coils and clean ducts directly reduce your building's energy spend.
- Equipment life. Coils, bearings, and motors last significantly longer when the system isn't fighting built-up restriction.
- Post-construction cleanup. Renovation and demolition work fills ducts with fine particulate that stays there until it's professionally removed.
Our Process
- System walkthrough with building engineering
- Access panel mapping and staging plan
- Containment and register protection with filter media + low-tack tape (no plastic — traps moisture)
- Source removal via mechanical agitation and HEPA-filtered negative air
- Coil, blower, and plenum cleaning
- Optional EPA-registered sanitizing application
- Post-cleaning inspection, airflow verification, and report
Who This Is For
Class A office towers, medical office buildings, hospitals, schools, hotels, data centers, and high-rise residential buildings where IAQ, tenant satisfaction, and system efficiency directly affect operations.
