Florida generator guide
Natural Gas vs Propane Generator in Florida
Both fuels run a whole-home generator well. The right one for you comes down to what's already at your house and what your lot allows. Here's the straight comparison, without the sales spin.
About five minutes. No salesman, no all-day window.
Natural gas: if the street already feeds you
If you have natural gas service, it's usually the simplest path — an endless supply piped to the unit, nothing to refill. The catch is line capacity: a large generator needs enough gas volume and pressure, and an older or smaller line may need an upgrade to feed it without starving during a long run. That's a real cost to know about up front, not at the install.
Propane: the Florida workhorse when there's no gas main
Much of Florida has no natural gas at the street, and propane is the answer. It stores on your lot in a tank we size to the generator and your expected runtime, and it burns clean. The trade-offs are tank siting (setbacks, look, and anchoring matter, especially in flood and wind country) and remembering it's a finite supply you keep filled.
GENERasic sizes the tank to the unit and errs toward enough runtime, so the number you see already assumes a tank that won't leave you short.
How GENERasic prices each
You don't have to figure out your gas line's capacity or what size tank to buy — that's our job, derived from your photos and address. If you already own a propane tank, that drops the price, and the app accounts for it. Either way you get one committed number for your fuel reality, not a fork of homework handed back to you.
Common questions
Which is cheaper to run, natural gas or propane?
Natural gas is usually cheaper per hour and never needs refilling, but only if you already have a gas main with enough capacity. Propane is the practical choice where there's no gas at the street — and GENERasic prices whichever fits your address.
Do I need to buy a propane tank separately?
No. GENERasic sizes the tank to your generator and runtime and includes it in your committed price. If you already own a suitable tank, your price drops to reflect it.
What if my natural gas line is too small for a whole-home generator?
It can need an upgrade to feed a large unit — a real cost we'd rather you know up front. GENERasic flags fuel as a price driver so there's no surprise at install.

GENERasic pulls the real property, flood, and elevation data for your exact address and returns one all-in installed price — sized to your home, your fuel, and your flood elevation. The vetted local installer confirms it on site.
