How long does Duct Cleaning usually take in Cary, and when is it recommended?
- 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.
- How does commercial duct cleaning differ from residential service in Cary?
- Commercial jobs typically involve larger air handlers, longer duct runs, and more complex zoning, requiring night or off-hour work to avoid business disruption. Commercial teams use heavier-duty negative pressure equipment and often provide detailed access plans. Confirm experience with similar commercial systems before hiring.
- What documentation should a Cary commercial client request after duct cleaning?
- Request a written report with scope, before/after photos, and any airflow or leakage test results tied to the 2021 NC Energy Conservation Code. Also ask for equipment logs, containment measures used, and recommendations for follow-up maintenance. Clear documentation helps with building compliance and warranty claims.
