Customers say: Quick response

"bought new path lights for our home. tried to install myself. Out of 8 lights only two came on. in addition, couldn't remove old lights from wires due to horrible clips from old lights. In about 20 minutes after the job started half of my lights were working. he wired them the way i asked so i didn't have to worry if one failed...i could replace without those darn clips. Just looking outside and finally seeing them work made me so very happy. the lights came on tonight at dusk. I could hardly wait to see them. I've been outside 3x since dark. I just cannot believe how great they look. he even replaced light bulbs and checked my eye on my lamp post. all is very very well here thanks to midnight sun. amazing and fast job. definitely a favorite contractor."

"Jordan Blake from Exceptional Electric rocks! His communication prior to coming out was very thorough, and he was able to schedule us in two days. While he was onsite he found multiple items from years of DIY wiring, one major one. He clearly communicated al recommended changes to better match current code. As to the major item, he discovered the transformer was causing over-voltage delivery into our main! He had me call United Electric, and the linemen were out even before Jordan left – kudos to U.E. Cooperative – and replaced the transformer on the pole. All this for what started out as just putting a new 30A circuit in for a mini-split! Our mini-split is not yet on site, so we look forward to having Jordan back to the farm to complete the electrical plus a couple of the found issues next week. He is so knowledgeable. I highly recommend him. His sense of humor is also a delight, and my husband enjoyed learning and discussing many things with him. His prices are excellent."

Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.
