The Benefits of Routine Generator Maintenance
There are many reasons you should invest in professional maintenance for your whole-home generator. Some of the primary benefits you’ll enjoy include:
- Safety: Regular maintenance ensures tight and secure gas and electrical connections. This significantly reduces the risk of fire or electrocution.
- Reliability: Blackouts and brownouts are unpredictable. With a properly maintained generator, you’ll know your system is ready when the grid fails.
- Warranty preservation: Professional maintenance helps preserve existing manufacturer warranty coverage.
- Longevity: Keeping your generator well-maintained is the key to extending its serviceable lifespan. It also reduces your long-term repair costs.
- Energy efficiency: A well-maintained generator operates more efficiently, lowering per-hour operating costs.
Expert Generator Maintenance & Tune-Ups

Standby generators and whole-home generators require regular maintenance. Whether you have a Generac generator or other system, falling behind on maintenance can cause your system to malfunction when you need it most.
For optimal performance, we recommend performing maintenance after every 100 operational hours. It’s also best to schedule annual maintenance to ensure all components and system functions operate as designed.
Because each generator has different maintenance requirements at every 100-, 200-, 300-, and 400-hour increments, we’ll consult your generator’s requirements during each visit to determine what specific maintenance is required.
