Generator Maintenance in Houston

Generator maintenance in Houston is what makes the unit start when the storm hits. Most failures we see come from dead batteries, old oil or pests in the housing. A yearly visit catches them early.

Signs your generator needs service

  • It has been over a year since its last service
  • It ran many hours during the last outage
  • The battery is three or more years old
  • The weekly exercise run sounds rough or skips
  • The control panel shows a warning or a maintenance light
  • You see oil under the unit
  • Ants, wasps or rodents got inside the housing
  • Hurricane season starts June 1 and you want to be ready

Good to know in Houston

Houston heat and humidity are hard on batteries and wiring. Fire ants love the warmth inside a generator housing and can short the controls. After a long outage like Beryl, many units ran for days and were due for oil right away. We plan visits before June so you are ready for hurricane season.

Maintenance does not need a permit. Repairs to the transfer switch or wiring must be done by a TDLR-licensed electrician, and gas repairs by a licensed plumber with a gas endorsement.

Questions about generator maintenance

How often should a generator be serviced?

At least once a year, and after long outages. Check your maker’s schedule, since some list service by hours run.

Do you service brands you didn’t install?

Yes. We service most home standby brands, including Generac, Kohler and Briggs & Stratton.

Will skipping service void the warranty?

It can. Many makers expect service on schedule. Keep your records.

What should I check myself?

Look for a green status light, keep the area clear of plants and listen to the weekly exercise run.
