"The owner communicated with me quickly and sent two techs out to install my ring video doorbell and I’m happy with the work. I will hire them again soon to install a ceiling light fixture and some cafe patio lights."

"I was pleased with the work done by Allred Electrical. The process of removing my old fuse box, installing a new panel, having the town inspector come out, and the electric company coming out to remove the old outside box took longer than expected. Allred was short handed because an employee was out due to illness but they have no control over the town inspector's nor Duke Energy's schedules. Even though the process from start to finish took a little longer than expected I was only without power for part of one day by they came back on a Sunday to check on something I thought was a problem. The only problems I can think of were the fact that I couldn't get a detailed invoice prior to the job of what was to be done with a cost break down and I'm waiting for them to come back to add outlets. So I will update this review once the full job is complete."

Customers say: True professional

"Great experience with Dr. Sparky Electrical Service. Angel was our electrician, and he was knowledgeable, professional, and thorough. He took the time to diagnose the issue and clearly explain what was causing the problem and what needed to be done to fix it. The service was reasonably priced, and I appreciated the communication throughout the process. I would definitely recommend Dr. Sparky and Angel for anyone needing electrical work."

Generator Install FAQs, answered by experts

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.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.
