"Kevin was great! He was on time and took the time and effort in explaining all the electrical stuff we needed to do around the house. His attention to detail was amazing! We needed to install hanging lights above our dining table and add outdoor lights to our garage. He was meticulous and precise and explained everything well. It was cost effective and quick! 100% recommend Harrison and will hire them again"

"We needed an outlet and light + switch installed for our radon system. While the cost was a bit more than we were hoping, the person that came out had it done within 2 hours and its one less thing on our to do list! I also appreciate that Hero does not charge a trip fee like one of the other companies I had come give a quote."

"I strongly recommend using Revelation Electric for all your electrical projects. They have a great work ethic and they are extremely knowledgeable. Revelation Electric did a whole house upgrade to all my electrical units. My house was built in 1890 and it had to get all new electrical components from the ground-up. Revelation Electric installed new electric panels, lights, ceiling fans, gfci outlets in the bathrooms, sensor lighting and a lot more. I want to thank Brandon who is the owner of the company for helping me throughout the whole process. He was very friendly and had a lot of great ideas that improved my house. Revelation Electric and Brandon are the True definition of 5 Star and 5 Diamond."

Generator Install FAQs, answered by experts

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

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

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.
