Generator Installation & Repair in League City, TX

Hurricanes, tropical storms and summer grid strain make backup power a must on the Gulf Coast. K.R. Allen Services installs, repairs and maintains standby generators for commercial buildings and homes across League City, Dickinson, Webster, Friendswood, Texas City, Galveston and the Houston Bay Area.

Standby Generator Installation

We size the generator to the loads you need to keep running, install the pad, gas or fuel connection, automatic transfer switch and wiring, and handle permits and inspections. Options range from whole-home units to large commercial generators.

Commercial Backup Power

For offices, medical and dental practices, restaurants, cold storage, warehouses and industrial facilities, we install and service generators and transfer switches that protect refrigeration, data, security and critical equipment.

Generator Repair

If your generator won't start, won't transfer, shuts down under load or shows a fault code, we diagnose the engine controls, batteries, transfer switch and wiring and get it back in service, on all major brands including Generac, Kohler and Cummins.

Generator Maintenance

Scheduled maintenance before hurricane season, including oil and filter changes, battery testing, load testing and transfer switch checks, makes sure your generator works when you need it.

Generator FAQs

What size generator do I need?

It depends on which loads you want to keep running, such as AC, refrigeration, well pumps, medical equipment or the whole building. We do a load assessment and size the generator to match.

What is an automatic transfer switch?

An automatic transfer switch senses a power outage, starts the generator and switches your building over to generator power, then switches back when utility power returns.

Do standby generators run on natural gas?

Most standby generators run on natural gas or propane, so there is no fuel to store or refill during a long outage. We handle the gas connection as part of the installation.

How often should a generator be serviced?

Standby generators should be serviced at least once a year, with oil, filters, battery and transfer switch checks, ideally before hurricane season.

Do you install commercial backup generators?

Yes. We install and service generators and transfer switches for offices, medical and dental practices, restaurants, cold storage, warehouses and industrial facilities.
