"I would recommend Current Electric to anyone! They are affordable, professional, and customer service oriented. We had Eric as our electrician and he went above and beyond for us. We had a new outlet installed, can lights installed, and ceiling fans installed. He kept us informed the whole time with updates on progress, time frames, and got our input along the way. We will definitely be using Current for all of our electric needs."

"This is the first time I used Mr. Sparky, and they will definitely be my new go to electricians! I love that they are a small locally owned business! I called about a small non-urgent project, and they were able to come the same day, despite being backed up due to many local flooding issues. Kasey was extremely friendly and helpful on the phone and communication was excellent from start to finish. James showed up on time and was very sweet, yet professional, and my cats even loved him :) He was respectful of me and my property, and took care of my issue in no time. The price was very reasonable! I will definitely call them again, and would highly recommend!"

"All of their technicians were very professional and polite and helped me understand what was going on every step of the way, from the initial inspection, diagnosing the issue, deciding on a new furnace, and through the installation process. When the inspection showed that my furnace was no longer working, they even shuffled some appointments around to make sure I had working heat before it started getting too cold outside. Not only did they do a great job installing the new furnace and AC, they went out of their way to clean up the basement and duct work a bit and left things looking even better than when they got there! Mike was my technician for the initial inspection and Austin worked on the Furnace and AC install. There were a couple other techs with them as well who's names I didn't quite catch, but all of them were great!"

"Elliott does great work for a great price. He installed a new 100 amp breaker box and updated some of the house wiring to accommodate the new service. He also wired the newly renovated basement with all the wiring and installed all the outlets, switches and drop ceiling LED lights that have dimmer capability. He is meticulous in what he does."

Generator Install questions, answered by experts

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.
