Sigma Companies LLC

About This Contractor

Sigma Companies LLC supports mission-critical generator projects throughout the Reno region from its Las Vegas, NV base. Resistive load-bank testing validates that a unit can carry full rated load and prevents wet-stacking in lightly loaded engines. Fuel system design — day tanks, bulk storage, and runtime sizing — determines how long a facility can ride through an extended outage. EPA Tier 2 and Tier 4 emissions compliance and air-permit familiarity shape generator selection and siting. The firm holds a 4.5-star rating across 26 customer reviews.
