Generator Sales & Installation

Generator Sales & Installation

Install a whole home generator to keep your home running automatically through outages.

What is a Home Standby Generator?

A home standby generator is a permanently installed system that turns on automatically during an outage. Installed outside your home and connected to natural gas or propane, it restores power within seconds and can keep essentials like lights, refrigeration, and air conditioning running until utility power returns.

  • Starts automatically and restores power within seconds
  • Powers your home, including air conditioning and major appliances
  • Runs on natural gas or propane

Choosing the Right Fuel Source

Both natural gas and propane provide reliable backup power. Your choice depends on gas availability at your home and your power needs during outages.

Natural Gas

Connects directly to your home's gas line and supplies fuel during outages, as long as gas service remains available. Common in urban and suburban areas with natural gas infrastructure.

Advantages

  • Continuous fuel supply, no tank to refill
  • No on-site tank or fuel storage
  • Automatic, hands-off operation
  • Often the most convenient option when gas service is already in place

Considerations

  • Natural gas service must be available at your property
  • Availability varies by location and neighborhood

Propane

Draws fuel from an on-site propane tank. A popular choice in rural areas and communities without natural gas infrastructure.

Advantages

  • Works with or without natural gas service
  • Fuel stored on-site ensures availability during severe weather
  • Tank size can be matched to your home and runtime goals
  • Some models deliver slightly higher rated output on propane

Considerations

  • Requires an on-site tank and proper placement
  • Refilling is needed after extended use

During your free site assessment, our certified technicians will evaluate fuel options at your property and help you choose the best solution. If propane is recommended, we'll suggest the right tank size based on your home's power requirements
