"I hired K & K to install a range hood. There was no electrical there previously so they had to run electric. I also had them install a new light fixture and remove an exhaust fan. K & K did excellent work and even repaired an electrical box that another contractor had installed. I was given a great estimate and was charged the estimate price. Would definitely use again and recommend."

"Russell was prompt, very polite and helpful. He explained everything and pointed out where my old rowhouse differs from newer codes. (Grandfathered until I want to sell.) There was an upsell on an annual plan, but it will save some 15% on some planned upgrades, so I went with it. Dawn, office support, also was friendly and pleasant to work with. She gave me a follow-up call next morning after my multi-company query through Angie's. My inquiry detailed list of three small repairs did not get other takers, so no real cost comparison, but I feel the price was fair-- $500 for about 2 hours, including the plan and dispatch fee."

"They did a great job capping the live wires from a wall we tore down and got our recessed lighting in the basement working with the switches. Reasonable priced and professional. Very considerate of the space and timely in completion."

Generator Install questions, answered by experts

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
