"L I put request on Home advisor/Angie's list. Out of all the request this is the only company that responded to my request. Not only did he respond within 30 minutes, he came out the same day, installed my ceiling fan, and finished everything up within one hour. Most kind efficient, professional, and very knowledgeable company. I would definitely use them anytime and every time. Thank you so much, Kevin."

"They checked my generator and said nothing was wrong, that the problem was probably with the electric companies transformer. My problem still exist. The electric company sent people out to check the current coming to my house and said everything is okay. They are going to install a monitor to check what is going on when there is an outage. So as of now my generator does not come on."

"Callahan worked me in during a busy week before the 4th even though it was a cold call. I did not know him.. The electrician was exactly on time at 8AM and he wore a mask. He did a perfect job, and went out of his way to make the wire out of site as it was installed across my garage.. Even though it took a little longer than anticipated, he still charged me the quoted price.. I will definitely call him again for all my electrical work."

"He did a pretty good job and the price was pretty good too. He charged $500 for one time, but he was here for a long time because he had to do all the work here. What I liked about him that he had to run wires, he would hide them behind the walls and you don’t even see the wires."

Generator Install FAQs, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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.

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.
