FAQ
Questions Long Island customers ask.
Do you handle commercial tenant fit-outs on Long Island?
Yes. We wire offices, retail, and restaurant build-outs — lighting, dedicated equipment circuits, data infrastructure coordination, and emergency lighting — and we work clean around your schedule.
Can you do three-phase work?
Yes. We install and service single- and three-phase equipment circuits and coordinate service upgrades with PSEG Long Island for small commercial and light-industrial spaces.
Will an LED retrofit really lower my bill?
Typically, yes. Swapping older fluorescent or HID lighting for LED with occupancy sensors usually cuts lighting energy substantially, and incentive programs may offset the cost. We'll lay out the numbers.
Can you work after hours to avoid downtime?
We stage commercial work to minimize disruption and can schedule key cut-overs outside business hours when needed.
