"Walker Electric did a great job each time I hired them. On separate occasions they installed two ceiling fans, installed an electric outlet, and finally installed a full house generator. I will have them out again when there is need, and recommend their service to family and friends."

"My husband and I recently had a large detached garage built in our back yard. We were having a hard time finding an electrician. We found Stickler's Electrical Service on Angi and we are very pleased that we did. Anthony Stickler is a a true professional and highly skilled at his craft. He installed all of the wiring, outlets and switches, as well as the panel. He did a phenomenal job! He is prompt, responsive, reasonable and honest! Highly recommended!!"

Customers say: Quick response

"One of my rental homes needed electrical attention before an inspector would agree to come in. It was an emergency situation and Matt was very helpful. I originally called him after hours and was pleasantly surprised that I was able to talk to him. He patiently listed to my situation and came the next day first thing in the morning. He performed the requested work I needed. Then, worked a miracle and managed to bring the inspector the same day. Not only that, but he also called Duke Energy so that they would turn the power on the same day. I was very impressed with how reliable, honest, and prompt Matt was, and all for a very reasonable price. I will definitely call again if I am in need!"

Generator Install questions, answered by experts

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
