Duty cycle. A residential TV runs maybe 5 hours a day. A restaurant TV runs 12–16. A gym TV runs 18. Commercial-grade displays from Samsung, LG, and Planar are rated for 16/7 or 24/7 operation. Installing a residential TV in a commercial setting voids the manufacturer warranty and usually fails within 12–18 months.
Structured cabling. Commercial work in DFW is held to BICSI and TIA-568 standards. Cables get labeled at both ends, tested for continuity and performance, and documented on as-built drawings. Residential wiring standards don't apply — a "we tested it and it works" handoff won't pass a commercial inspection.
Code compliance. Plenum-rated cable in return-air spaces. Fire-rated penetrations where cable crosses rated walls. ADA-compliant mounting heights for public displays. Code-compliant grounding for mounted equipment. Commercial work gets permitted and inspected; residential typically doesn't.
Insurance. Commercial clients usually need additional-insured endorsements on their building or property policies. This is a standard request that gets handled within 24–48 hours — any contractor who can't or won't provide it shouldn't be on commercial projects.
Serviceability. Residential installations hide wiring because it looks better. Commercial installations hide it too, but with planned access points — equipment closets, pull strings in conduit, ceiling access panels — so a broken piece can be swapped without cutting into walls or ceilings. Downtime costs commercial clients real money.
