"Very good price to put switch to run generator installed an electrical switch (not a lockout) to convert to generator power during power outage. Tech stayed on communication throughout. He was on time and got the job done in one visit. He brought a better cover the next day than the one furnished with the receptive. I highly recommend his work."

"It would be very difficult, if not impossible to find another company that has the commitment to excellence that M&M Electric has. I had them put in new central heating and air in my house and was surprised at how quickly they installed everything while still maintaining a high quality standard and while paying attention to every detail. Very impressive considering what they charged for the install was way less than what I was expecting to pay. I will definitely keep their number handy for any other jobs that pop up."

Generator Install questions, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
