Generator installation cost in Texas

Generator installation cost in Texas depends on the size of the generator, the transfer switch, the distance between the generator, the panel and the fuel source, whether gas line work is needed, and local permit requirements. Whole house units cost more than essential-circuit systems. We size the system to your loads and quote it as a complete installation.

Generator installation: common questions

What size generator do I need for my Texas home?

It depends on what you want to run. Central air conditioning is usually the largest load. We perform a load calculation and can size a generator for the whole house or for selected circuits.

Do you install Generac generators in Texas?

Yes. We provide Generac installation in Texas as well as electrical installation for other standby generator brands.

Does a standby generator run on natural gas or propane?

Either. Homes with natural gas service usually connect to it. Homes without it use a propane tank. The fuel supply has to be sized for the generator.

Can I plug a portable generator into my house?

Only through a transfer switch or interlock kit with a proper inlet. Backfeeding through an outlet is dangerous to you and to utility line workers. We install safe portable generator hookups in Texas.

How long does whole house generator installation take?

The electrical installation is often completed in a day or two once the pad, permit and fuel connection are ready. We go over the full timeline when we quote.
