Generac Power Systems, Inc. manufactures a complete line of emergency automatic home standby generators that can be installed during new construction or retrofitted into existing residences and businesses. Residential emergency home standby generators are permanently installed outside (similar to an air-conditioning unit), supply electrical power to all pre-selected lights and appliances, and are powered by either natural gas or LPG. Models range from 7,000 to 45,000 watts. They work with a matched automatic transfer switch that responds within seconds when utility power shuts down, even when no one is home!

Generac is truly a vertically integrated manufacturer. From the core of the engine to the controls, we design and build our complete product. This is precisely why we stand so strongly behind it with one of the best warranties in the industry. With intensive control over our engineering through manufacturing, we're able to ensure that our products are quiet, powerful and reliable.

We are authorized sales and service dealers for Guardian generators and factory trained to provide professional service for installation, repair and warranty services.

Generators of Houston can plan, design and install automatic standby generators. From 7kw air-cooled to 40Kw liquid cooled systems, we will layout and design the most cost effective solution for your home.

Even if you have purchased your generator from another source, Generators of Houston can provide term service contracts. We also stock maintenance parts and tuneup kits for your Guardian or Generac generator. See our service program page for more details.
