Standby generator installers in Texas
Texas runs its own power grid, and it fails in ways the rest of the country watches on the news — Winter Storm Uri left millions of Texans freezing in the dark in February 2021, Hurricane Beryl knocked out power to more than two million homes around Houston in the summer of 2024, and every August ERCOT asks the state to conserve as demand pushes the grid to its limit. A standby generator starts itself within seconds of an outage and carries the AC, refrigerator, well pump, and medical equipment until the utility is back. These are the Texas companies that install and service them.
How this list is built: We found these companies by reading Texas generator-installer websites, then classified each one: is standby-generator work its core business, is it a factory-authorized dealer, or is it an electrical or HVAC contractor that also installs generators?
Specialists and authorized dealers are listed first.

Common questions about standby generators in Texas
How much does a standby generator cost installed in Texas?
For a typical Texas home, expect roughly $9,000–$15,000 all-in for a
whole-house air-cooled standby generator (about 18–26 kW): the unit
itself, the automatic transfer switch, a concrete or composite pad, gas
piping, electrical work, and permits. Partial-home units (10–14 kW)
covering essentials can land in the $6,000–$9,000 range. Liquid-cooled
units for large homes run well past $20,000. Fuel type matters: natural
gas is cheapest to run where a city gas line is available; much of rural
Texas runs on propane, which requires a tank.
Do I need a permit to install a generator in Texas?
Inside an incorporated city, yes — a standby generator installation
involves an electrical permit (and usually a mechanical/gas permit)
pulled with the city building department, followed by inspection. In
unincorporated county areas, Texas gives counties only limited
authority to require building permits, so the paperwork can be lighter —
but the electrical work must still be performed by a licensed Texas
electrical contractor, and the gas connection still has to meet code. A
reputable installer handles permitting as part of the job; treat one who
suggests skipping required permits as a red flag.
What size generator do I need in Texas?
The honest answer is a load calculation, which any good installer
performs during the site visit. Texas sizing is usually driven by
air conditioning: essentials only (a furnace or AC zone, well pump,
fridge, some lights) fits in 10–14 kW; a typical whole house with
central AC runs 18–26 kW; large homes with multiple AC units, a
pool, or a well need more. Oversizing wastes money up front;
undersizing means the generator sheds loads — often the AC — that you
wanted covered during a summer outage.
Generac, Kohler, Cummins, or Briggs & Stratton — does the brand matter?
All four build reliable home standby units; what matters more is the
installer and the service relationship afterward. Generac has by far
the largest Texas dealer network, which means parts and warranty techs
are easy to find; Kohler and Cummins have strong dealers across the
major metros. A factory-authorized dealer can handle warranty work on
its brand — worth weighing when brands otherwise look similar. Use the
brand pages here to see who installs and services each brand near you.
How long does installation take?
The on-site work is usually one to two days once the unit is in hand:
set the pad and unit, run gas and electrical, mount the transfer
switch, and commission. The calendar time is longer — site visit,
quote, permits, and (in the rush after a big freeze or hurricane) unit
availability can stretch the process to several weeks. Ordering ahead
of hurricane season beats competing for a generator the week after a
storm.
What maintenance does a standby generator need?
Annual service — oil and filter, spark plugs on schedule, battery
check, and a load test — plus the weekly self-test the unit runs on
its own. Texas heat and humidity make the cooling system and battery
worth watching, and you want the unit proven before hurricane season,
not during it. Many Texas installers listed here offer maintenance
plans, and several service brands they don't sell. Neglected
maintenance is the most common reason a generator fails to start when
the grid goes down.
