"Mr. Johnson and his crew have performed a fewjobs from lighting installations, to doorbell repair, to rewiring. Every job has been done well and at a reasonable price. The workers were respectful and very helpful at explaining the work they did before they left. What really set this outfit apart is Mr. Johnson himself. He always returns calls, his crews show up on time and perform the work expediently. On top of this, when I have had questions about other electrical concerns, Mr. Johnson takes time to have a phone call to consult on the issue. Mr. Johnson and his company are of high integrity and I would highly recommend them for any residential electric work."

"I recently had Narek install a Tesla wall connector in my garage in Los Angeles, and I could 't be happier with the service I received. Narek was not only professional and knowledgeable, but he also got the permit required for the installation very quickly. He arrived on time and took the time to explain the installation process and answer any questions I had. The installation itself was done quickly and efficiently, and Narek made sure to clean up after himself once the job was complete. He also took the time to show me how to use the wall connector and ensure that it was working properly before he left. Overall, I would highly recommend Narek to anyone looking to install a Tesla wall connector. His professionalism, attention to detail, and expertise made the process easy and stress-free, and I am thrilled to now have a reliable and efficient way to charge my electric vehicle at home."

"I thought Paul and his installer were rock stars. I bought a new fan and the ceiling fan company where I bought it couldn't do a quick installation so I looked in here at Angies list and found that Paul at Fairway Electric was highly recommended. And the review was more than accurate. Paul responded immediately and had someone out the next day and installed my ceiling fan (something i did NOT want to do myself). And he even charged me a bit less than Paul quoted. Later---there was a frequency problem with the ceiling an light that made it dim occasionally---(caused by a neighbor who had a remote control with a similar frequency). Paul sent his repairman out (no additional charge) and changed the frequency. I'd call Paul back in a millisec if I had another ceiling fan installation or for electrical work based on my excellent experience dealing with him."

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.
