Price

Cost to install a home generator:

  • Low$1,949
  • Average$13,800
  • High$21,000

What affects cost?

The cost to install a whole-home generator depends on several factors, including:

  • Number of appliances you want to power. The more appliances you want powered during a power outage, the more powerful your generator will need to be–and more powerful generators cost more.
  • Adding a concrete slab. Depending on your local codes, you may need to pour a concrete pad for your generator. This will increase your overall costs.
  • Whether you need an upgraded gas meter. Sometimes, a gas generator will need larger gas meters than what the home currently has. If you need to upgrade the gas meter, this will increase costs.
  • Company you hire. You’ll pay more for skilled, experienced techs who knows how to properly install your whole-home generator.

Customer Testimonial

“They took care of our request in a very short time...“

Every one was very friendly, starting with your telephone operators. They took care of our request in a very short time and had someone here the next day. The technician, Phillp was also friendly and ready to solve our problem. He took his time explaining what was wrong and how he was going to meet our needs. We would certainly call Jon Wayne again in the future for any problem.
