Benefits

The Benefits of Installing a Home Generator

A professionally installed generator brings comfort, safety, and convenience to your home during outages. Some benefits of installing these appliances include:

  • Reliable power. A home generator that kicks in automatically when your primary power source fails, keeping you from fumbling in the dark, dealing with spoiled food, or worrying about lost work time.
  • Damage prevention. Generators help protect your home electronics and appliances from power surges when electricity returns after outages.
  • Comfort and peace of mind. With a generator, your home stays lit, cool, and connected, no matter what's happening outside.

Replacement Signs

Signs It Might Be Time to Replace Your Generator

Even the most reliable generators wear out over time. If you suspect your generator is nearing the end of its service life, look for these common red flags.

  • Unusual noises: Grinding, knocking, or high-pitched whining noises can indicate internal wear or damage. If your generator struggles, have Jon Wayne check it immediately.
  • Power failures: If your generator doesn't start or can't keep up with your power needs, it's likely time for a repair or full replacement.
  • Increased fuel usage: Older units experiencing a sudden jump in fuel use may require replacement due to aging parts.
