FAQs
Do I need a home backup generator or a battery?
Batteries are silent and great for short outages and smaller loads. Generators power entire homes for days and handle high-draw appliances (furnace/AC, well pump, ovens). Many clients pair batteries with generators; we’ll help you choose.
How long will a backup generator keep my home powered?
As long as fuel is available. Natural-gas units can run for days; propane runtime depends on tank size and load.
What maintenance does a generator need?
An annual service (or every 100 to 200 hours) with oil/filter, spark plugs, air filter, diagnostics, battery check, and exercise test. Schedule your whole home generator maintenance each fall before winter storms hit.
Do I need to replace my generator?
Hopefully not, but it depends. Consider a replacement if your unit:
- Is 10-15+ years old
- Needs frequent or major repairs
- Fails load/exercise tests
- Parts are obsolete
- The unit is undersized for new home loads such as EV chargers, newly finished basements/additions, larger HVAC systems, etc.
- Shows corrosion or enclosure damage,
- You want to switch fuels and/or cut noise with a newer, more efficient model.
