AutoZone’s Whitten Road location in Memphis, Tennessee experienced a critical reliability issue with its Generac commercial standby generator.

Although the generator had been installed less than a year earlier by another contractor, it had never operated successfully during a power outage.

In an area like Memphis - where severe storms, high winds, and grid interruptions are common - this left the business vulnerable to downtime, lost revenue, and disrupted operations.

Our Generator Inspection & Diagnosis

Our Memphis-based generator technicians conducted a comprehensive on-site inspection, evaluating:

• Generator specifications

• Natural gas fuel supply

• Gas pressure levels

• Installation configuration

• Manufacturer operating requirements

We discovered a natural gas pressure mismatch, a common but often overlooked issue in commercial generator installations:

• The building’s natural gas service delivered 2.0 lbs of pressure

• The installed Generac generator required ¼ lb of pressure

• No pressure regulator had been installed during the original setup

This incompatibility prevented the generator from starting and operating correctly.

AutoZone needed a local commercial generator service company that could quickly identify the root cause and restore dependable backup power.
