"Sebastian was top rate. On time, diagnosed issue, checked outlets & breakers. He had the right parts in the truck and was able to install new breakers (replacing the prone to fail AFI/GFI combo). Refrigerator is safe and the dishwasher/disposal is working again. Very happy with the great service and the on-the-job explanations that he had to help me be an educated customer. I will definitely use Sebastian on my coming up home improvement projects."

Customers say: True professional

"Pearson is the bomb! I was looking for an electrician and called Pearson; Sean, the owner, picked up, gave me a reasonable quote based on the job I described (installing two ceiling fans), and even anticipated a potential issue (needed different electrical boxes from the existing ones). He was also kind enough to recommend a particular brand that he knew was high-quality and long-lasting. He followed up with emails to confirm the appointment and quote. On the day of appointment, he showed up on time and prepared. He worked efficiently and even cleaned up after! I wholeheartedly recommend Pearson. Altogether super professional and lovely."

Not only is he focused and efficient, he reviews the work he completed and cleans up before he leaves. I've referred Brandl Electric to friends who were very pleased with their work as well."

Generator Install questions, answered by experts

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

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.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

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.
