"Klaus, owner of Resolute Electric, showed up initially to complete the estimate. Klaus was on time, professional and left us feeling we chose the right guy for the job. Klaus provided an estimate within 24 hours, we scheduled the date of the installation and Klaus arrived exactly when he said he would be there. He was very knowledgeable about what needed to be done, did not hesitate to get started and completed installing the flood light in exactly the area we wanted and removed power to the base board heating at the junction box. The flood light needed to be hard wired and Klaus was nothing less than stellar from the moment we met him to the time he left after completing everything we requested. Resolute's pricing is very fair and anyone that uses Resolute will 100% be satisfied with the price and work performed."

"I converted an attic into a 1 bedroom apartment with private bath, kitchen and laundry area years ago and contracted Brandon Oakley to do all of the electrical work. The job was completed timely, professionally and without any issues. Since then his company, Legendary Services, has expanded its services to now include installing back up generator systems and solar systems for sustaining your electrical needs during power outages. I have discussed these options with him and he is very knowledgeable and I am considering installing one or both of these systems in my home. I trust his judgement and his work based on great past experience."

Generator Install FAQs, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
