Whole-home generator installation cost factors:

  • Size: Generators range from 16 to 24kW (kilowatts). Depending on the size you need, your costs will vary. During your free estimate, Cooper’s electrician will carefully inspect your home’s appliances and electrical usage and help you find the right-sized unit.

  • Brand: Just like other appliances, certain generator brands cost more than others. At Cooper Heating and Cooling, we only install top-performing generators from trusted brands like Generac.

  • Fuel type: Generators are powered by various fuel types, including gasoline, natural gas, propane, diesel, and biodiesel. Natural gas is typically the least expensive to operate, but if you need to connect a new gas line, this may cost you more upfront.

  • Electrical upgrades: Since they power an entire home, whole-home generators rely on solid electrical connections. Prepare to budget for a new sub-panel, a transfer switch (to turn the generator on), and potential repairs to your home’s wiring.

  • Location: The farther away your generator is located, the more it will cost to connect to your electrical panel. And, unlike lightweight portable units, whole-home generators will need a gravel or concrete pad to sit on, adding to your setup costs.

"I'm extremely pleased...Would use again without hesitation."

Our electrical distribution panel needed replaced to prepare for an upcoming AC installation. Brett and Alex showed up and spent an entire summer day in the yard and on the roof with hot sun and eventually heavy rain bearing down on them. They were professional and effective. Brett’s attention to detail was extremely appreciated. I’m extremely pleased with the work and feel like cost is reasonable. The respect they both had for Cooper was also refreshing. Would use again without hesitation.
