- Commercial specialization. Provider lists commercial / facility / RTU duct cleaning as a distinct service line with scale detail (square footage, rooftop access, multi-zone).

How long does a typical "Duct Cleaning" visit take in Wilmington, and who needs one?
- How is commercial duct cleaning different from residential?
- Commercial systems mean rooftop units (RTUs), multiple zones, larger trunk lines, and roof or lift access — jobs are bid on system access and after-hours scheduling, not square footage alone. Kitchen grease-exhaust work adds code requirements residential jobs never have.
- What is NFPA 96 and does it apply to me?
- NFPA 96 is the fire-safety standard governing commercial kitchen grease-exhaust cleaning — it applies to restaurants and any facility with commercial cooking. It sets cleaning frequency by cooking volume and requires documentation, so use a provider who cleans to that standard.
- Do commercial properties in downtown Wilmington need different duct cleaning services than residences?
- Yes. Commercial duct cleaning often involves larger ducts, longer runs, and specialized filtration or negative-air containment for tenant safety. Downtown Wilmington businesses commonly require coordination with building management, off-hours access, and documentation for indoor-air-quality plans. Request a provider experienced in commercial projects who can provide a scope of work and containment plan tailored to the building.
- How do I find a contractor experienced with mold remediation inside HVAC systems in Wilmington commercial buildings?
- Look for contractors who provide camera inspection footage, negative-air containment, and references for commercial mold projects. Ask whether technicians hold relevant IAQ or remediation certifications and whether the firm follows industry standards for HVAC mold work. For downtown or multi-tenant buildings, confirm experience in building-access coordination and written clearance criteria after cleanup.
