How to Prepare Your Home for a Generator Installation
March 30, 2026 5 min read
From sizing to fuel choice to permits — what to think about before scheduling a standby generator install.
Standby vs. portable
A standby (whole-home) generator is permanently installed, runs on natural gas or propane, and kicks on automatically within seconds of an outage via an automatic transfer switch. A portable generator is cheaper but requires manual setup, an inlet box, and refueling. For Arizona's monsoon storms and grid stress, most homeowners who want true peace of mind go standby.
Sizing it right
We do a load calculation based on what you actually need to run during an outage — AC, well pump, refrigerator, office, medical equipment. Oversizing wastes money; undersizing leaves you in the dark. A typical whole-home unit is 18–26 kW.
Fuel and placement
Natural gas is the easiest if your home is already plumbed; otherwise a propane tank is added. The generator pad needs clearance from windows, doors, and combustibles per code. We handle the site planning.
Permits and HOA
Most Yavapai County jurisdictions require a permit for the electrical tie-in and gas connection. If you're in an HOA, check noise and screening rules — we can help you choose a unit that complies.
