Whole House Generator

Generators for Houses

Whole-home generators are one of the smartest investments you can make as a southeast Michigan homeowner.  When the power goes out, regardless of the reason, you can still enjoy cool air or warmth, depending on the season.  No worries about the food in your refrigerator or freezer spoiling, hot water for the shower, etc.  Basically, you have the ability to generate power so life goes on!

Standby Generator Benefits

Sometimes referred to as “stand-by” or “automatic backup power” generators, a whole house generator makes it possible to power your entire home.  There are countless benefits of this type of generator over portable generators that most people use to power only one or two items, such as a refrigerator.  Benefits include:


  • Your HVAC system will be supplied with power, meaning your family stays comfortable
  • No more sitting in the dark, or leaving the house
  • Keep your home security system armed
  • Keep your well pump and/or sump pump operating
  • Preserve expensive and perishable foods
  • Some home insurance providers will offer a discount on premiums for those with whole-home generators
