Frequently Asked Questions About Generators

Do I need a whole-home generator in Alabama?

Yes. Alabama experiences frequent thunderstorms, heavy winds, and occasional ice storms, all of which can cause outages. A whole-home generator automatically restores power within seconds, keeping your HVAC, lights, and appliances running. It’s an investment in comfort, safety, and convenience for your household.

What size generator do I need?

The size depends on your home’s power requirements. Consider these factors:

  • Essential appliances like refrigerators and HVAC systems
  • Lighting and outlets throughout the home
  • Security systems and medical devices
  • Additional conveniences such as well pumps or internet routers

Our technicians calculate the load and recommend the right generator for your home, based on these and other considerations.

How long does a whole-home generator last?

Most standby generators last 10 to 15 years with proper maintenance. Regular servicing helps extend lifespan and reliability. If your generator is older, breaking down frequently, or unable to meet your household needs, replacement may be the best choice.

What kind of maintenance do generators need?

Regular maintenance keeps your generator ready for emergencies. Typical tasks include:

  • Checking and changing oil and filters
  • Testing the battery and connections
  • Inspecting fuel lines and transfer switches
  • Running system tests to confirm performance

Scheduled maintenance helps prevent failures when you need power most.

Can my generator be repaired if it stops working?

Yes. Many issues, such as electrical faults, battery failures, or fuel system clogs, can be repaired. Our technicians diagnose the problem and provide fast, effective solutions. If repair is no longer practical, we recommend replacement options that match your home’s power needs.
