We are a Generac authorized dealer for installation, maintenance and repairs. Our technicians are factory trained and provide custom installation of whole house generators to fit your power needs.

There are a variety of good reasons to be protected from power outages with a whole house generator. One of the most common reasons is someone in the home is dependent on medical devices that rely on electricity to operate or you have a well and need power for your water source. As one client said, “Knowing that my wife’s medical devices will work during a power outage allows me to sleep better at night. I no longer spend the night when weather alerts are issued wide awake.”

A whole house stand by generator works using a transfer switch that automatically comes on within seconds of a power outage and automatically turns off when power is restored until it’s needed the next time.

How much does it cost?

The general cost range is:

  • $8,000 – $8,500 Whole House 200amp INSTALLED
  • $9,500 – $10,500 Whole House 400amp INSTALLED
