Generac Generator Installation by Moorhead Service Company in San Antonio, TX Sized to carry your AC
Power That Stays On

Sized to Run the House, Not Just the Fridge

The most common generator mistake is undersizing — a unit that runs a couple of lights and the refrigerator while you sweat in the dark. We size the standby unit to carry what you actually need in San Antonio, including the AC.

Authorized Generac dealer, prices published, transfer switch and permit included.

Standby Generators in San Antonio

On the ERCOT grid, the question is when the power drops, not if. Here is how we do generators right in San Antonio.

Sized to Carry the AC

A South Texas outage in August without air conditioning is more than an inconvenience. We load-calculate the generator to start and run the condenser — the step most installers skip — so the house stays livable, not just lit.

The Well Pump Out on Acreage

On Bexar County acreage, no power means no well pump and no water. We size the unit to carry the pump along with the AC, because losing water in an outage is the part people forget until it happens.

Authorized Generac Dealer

We install and stand behind Generac air-cooled standby units, with the automatic transfer switch included so the generator starts itself the moment the grid fails. Prices published before install.

Permitted and Monitored

Generator installs are permitted and inspected, and we set up Mobile Link remote monitoring so you and we both know it is healthy before the storm, not after.

Why San Antonio Homes in Particular

We are a Guadalupe County company. The closest side of San Antonio to us — the northeast and east, the IH-10 and Loop 1604 corridor through Converse, Live Oak, and Universal City — gets the fastest windows. The far west side we still serve; we are just straight with you about timing instead of promising a truck in twenty minutes we cannot deliver. Call before noon and we can usually confirm a same-day window.

Generac Generator Installation in San Antonio — Questions

“We bought a 1940s home in Monte Vista and the panel was a Federal Pacific our insurance would not touch. Justin's crew swapped it, pulled the permit, and explained everything in plain English. Felt like dealing with a neighbor, not a salesman.”

“Called three places when the upstairs of our house would not cool. Moorhead was the only one who measured the load instead of just quoting a new system. Ended up being a zoning fix for a fraction of the price. Honest people.”
