What state is your home in?

Pricing varies by state due to differences in permit fees, labor costs, and local regulations.

What fuel source does your home have?

Standby generators run on natural gas or propane. For propane homes, your local propane supplier handles the tank-to-generator connection. Propane installation costs are quoted separately during your consultation.

How far is your electric meter from where the generator would sit?

The generator is typically installed on the side or back of the home near the electrical panel. Longer runs require more wiring and labor.

How far is your gas meter (or propane tank) from where the generator would sit?

For natural gas, line distance affects material and labor costs. For propane homes, your local supplier handles the tank-to-generator connection — propane installation costs are quoted separately during your consultation.

What do you want the generator to power?

Whole-home coverage powers everything. Essential circuits covers key items like lights, fridge, AC, and medical equipment.

How many stories is your home?

Multi-story homes can require additional wiring and conduit runs.
