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

Which Lake Charles "Duct Cleaning" option fits homes near the 82,430 population center?
- 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 duct cleaning projects in Lake Charles require different permits or insurance than residential jobs?
- Commercial projects often require higher liability limits and proof of business licensing specific to commercial contracting. Larger jobs may need site-specific safety plans and coordination with building managers. Confirm insurance coverage limits and request a written safety and access plan before scheduling work in office or retail buildings.
