Should your Generac run on natural gas or LP propane?

Fuel choice is a site decision: natural-gas meter and regulator capacity versus LP tank location, fill access, and underground piping. The wrong assumption shows up as a change order after the pad is poured.

Answer first

Fuel choice is a site decision: natural-gas meter and regulator capacity versus LP tank location, fill access, and underground piping. The wrong assumption shows up as a change order after the pad is poured.

01

Definition

What is this?

Natural-gas Generac systems connect to utility gas where capacity allows. LP systems use on-site propane storage with regulators and a designed fuel run to the generator.

02

When to use

When does this apply?

Use this when your property is off the gas main, when the meter looks undersized for a large standby load, or when a salesperson quoted only the generator without a fuel plan.

03

Failure modes

What goes wrong?

Assuming city gas reaches every rural Boyle or Mercer address. Placing a tank where the truck cannot fill. Ignoring clearance and HOA rules until inspection week.

04

Proof

Why trust this guidance?

Hurst scopes fuel strategy on the free Generac consult — including LP tank sizing and placement for approved generator projects — before equipment is ordered.

05

Action

What should you do next?

Book a fuel-path review with your Generac consultation.

Rural estates, farms, and wells often push LP. In-town Danville homes with adequate gas service often stay on natural gas when the meter and regulator support the load.

See LP / propane generator systems for the Act page, and Generac dealer one-stop for the full project sequence.

Questions homeowners ask

FAQ

Can Hurst install the propane tank?

Yes, for approved generator projects — tank sizing, placement, regulators, trenching coordination, and final connection as part of the standby-power scope.

Which fuel is cheaper?

It depends on local rates, runtime expectations, and whether gas is even available. We compare complete scopes, not sticker fuel myths.
