"Ben did a great job installing our bathroom exhaust fan. He was on time, very clean and charged me the price he quoted. He even wore protective booties over his shoes while inside the house. I'm now looking for more projects for Ben to do. Thank You again, see you soon Ben."

"Emanuel (and his daughter as helper!) did a great job installing a 240v EV charging station at my home last month. He was able to give me a bid after I sent him some pictures and rough measurements and when he came out to my home to do the installation, recommended a much better way to do the install (that no other electrician, even those who gave me bids after in-person visits, offered as an option). It's been working fine thus far.. I'd definitely recommend Emanuel. Thanks."

"Ray was instrumental in upgrading the electrical in my townhome, including installing new recessed lights, light fixtures, replacing receptacles with new ones and modern cover plates. He also relocated and installed a new subpanel providing dedicated circuits to appliances and the newly installed recessed lights. Ray is incredibly knowledgeable and very easy to work with and I would recommend him and happily use his services again."

Generator Install questions, answered by experts

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.

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.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
