"I had a great experience working with M&L Electrical Solutions. They were professional, communicated well, and completed the electrical work in a timely manner. They installed the exit signs and handled the wiring efficiently, and everything looks clean and well done. They also provided a referral for drywall repair, which I appreciated. Overall, very reliable and easy to work with. I would definitely use them again."

"This was such an easy experience for us. Everlight Solar did all the planning, completed all required forms, obtained permits, everything! When all approvals were in, they came and installed the electric and then the panels. It was turned on within a couple days. There has never been a problem with the system and we are delighted to be doing our part to reduce our carbon footprint for the planet. We have been very happy with the entire process, installation and service from Everlight Solar!"

"Hired Precision Power twice to help with various electrical needs… rewired my kitchen and then again to help with the finish trim outs. We will continue to hire him. Currently just waiting for our new chandelier to arrive so we can have him back out again! Thanks for the quality work and dependability!"

"Tree branch bent and ripped electrical lines from my house. After many, many phone calls Double U called me back and came out same day to inspect damage and determine exactly what they would need to repair the job. The company (Josh) kept in touch with me as we had to wait for the utility company to show up. Double U got everything fixed and even the utility company was very happy the way the work was done so that they could easily hook me up with power again. They were fast, efficient, friendly and explained everything fully so I really understood what was happening to my home."

"In 2019 I bought an older home and hired ICRA Electric to rewire the entire home including upgrading the electric panel. Aaron Mattingly (owner) was referred to me by someone I trusted. I typically only use contractors by referral. Not only was his bid lower than the other bids I had received, he was very flexible with my schedule and accommodating with changes I made throughout the job without gouging me. Aaron also provided practical electrical suggestions for future needs that I wasn’t even thinking about and ensured everything I wanted was completed according to code. I have never done an online review in the past, but it is rare these days to find a contractor that is more about making sure you will be happy with the final product for years to come than getting as much money out of you as they can. There are many reputable contractors out there. The challenge is navigating through the others who don’t want to be found out. ICRA Electric is one of the good ones."

Generator Install questions, answered by experts

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.
