"Simply amazing from start to finish! I can't say enough nice things about this company or the people that I dealt with. They were all professional, friendly and they did great work. They called me just minutes after I clicked their name on Angi's List and had someone out to give me an estimate and had my appointment date set in record time from most companies that I have dealt with for home improvement. I hate having people in my house working but I felt totally comfortable with them. The work they did was exceptional. We got a new power box (breaker box - whatever it's call) and a new meter and a couple of new outlets put in. We also got new smoke detectors throughout the house. They had to work around some issues and relocate a bit of pipe from out water filter system that was in their way. And they just took care of it without any complaints. I didn't have to do anything. They took care of it all and had the inspector come out and get it approved. I feel safe in my home now. I highly recommend this company and I will be calling them for any future electrical work that I need done."

"What made me inclined to go with Stephen Palmer was the statement that they specialize in older homes, and ours was built in 1926. Like many projects, Renny encountered several challenges in running the lines, including a light switch (that he was going to splice into) that was inadequately grounded and installed during previous work. While the whole project took over 5 hrs, that time was commensurate with the work required. We also had a couple light switch replacements done which took now time at all. Absolutely happy with the company and with renny in particular."

"Jeff really took the time to inform me what the work would entail, and even inspected the fan I needed installed in my bedroom. This is something the first electrician I called for a quote did not do, he was just in and out. I will absolutely be using JS Electric, LLC, for future services."

Generator Install questions, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.
