Whole house generator installation in Knoxville, TN
The week after a storm is the worst time to start shopping. Searches for whole house generators in this area run four times higher in January than any other month.
A standby generator sits outside on a pad, watches the incoming power, and starts on its own when the power drops. A transfer switch keeps your house separated from the grid while it runs, which is the part that keeps line crews safe.
On every whole house generator installation, we size the unit to what you actually want running, not to the whole house by default. Heat, well pump, refrigeration, and a few circuits is a much smaller and cheaper machine than everything at once.
What a generator usually costs
A partial house standby unit, installed, typically runs $6,500 to $11,000.
A whole house unit large enough to carry central air runs $12,000 to $18,000 installed.
A portable generator inlet with an interlock kit is a much cheaper option at $700 to $1,400, if you are willing to start it yourself.
Estimates are free. Service calls carry a diagnostic fee.
