Generator Repair in Houston, TX

Signs your generator needs repair

  • The control panel shows a red light or fault code
  • It runs but the house stays dark
  • It shuts off when the AC kicks on
  • It surges, hunts or sounds rough

Good to know in Houston

During and right after a Houston storm, parts and techs are in short supply. Units that sat through a flood need a full check before they run. Lightning and grid surges can damage controllers, so we check for surge damage too.

Electrical repairs must be done by a TDLR-licensed electrician, and gas repairs by a plumber licensed by the Texas State Board of Plumbing Examiners. If you smell gas, leave the area and call CenterPoint or 911 first.

Questions about generator repair

Why won’t my generator start?

A weak battery is the most common cause. Low oil, low gas pressure and a tripped breaker on the unit are next.

Is the repair covered by warranty?

Maybe. We check the serial number and file the claim with the maker if it is covered.

Do you come during a storm?

We take storm calls 24/7 once it is safe to drive. Plan members are first in line.

Can a flooded generator be saved?

Sometimes. Don’t start it. We check the engine, controller and wiring first.
