"These guys were prompt, professional, and their prices were very fair. Brandon Neustel came to our house and added a generator inverter switch in less than an hour. Could not be happier with the work."

"These were two separate jobs at two different times. Each job was handled very, very professionally from the point of contact to the time the installations were completed. Each person we dealt with was extremely professional, very pleasant to work with and very helpful. Both times we used RK Electric we had wonderful experiences, which is a pretty difficult thing to find these days. If we need any type of electrical work in the future, RK Electric will absolutely be the company we call!"

"Arrived on time. Job done well. Did show up without the right outlet in the truck, so there was a missed communication between scheduler and electrician. He had to run to Home Depot. No issue on my side, bit comms could have been better within the company."

"Highly recommend Gerryn. Great electrician and super nice and professional guy. Got my home EV charger installed perfectly. Showed up when he said he would, gave us a fair price and was just a pleasure to interact with. After he finished installing the charger, he helped us with a few other small electrical needs we had around the house. Will definitely hire him again for any future electrical needs."

"Ideal experience with this company! They contacted me and came out to make the bid the same day I contacted them. They were super flexible and worked to accommodate my schedule. I needed to wait until my EV charger arrived from the manufacturer. They came out the day after it arrived, installed the unit in under two hours, and it's been working flawlessly ever since. Don't let their name fool you--John's Waterproofing is expert at electrical work! I will use them again."

"This company is awesome. A person contacted me to inquire about the job and he was very professional. He gave me a quote and was able to get someone to come out to install the lighting fixture the next day. However, someone was close in the area where he was able to be at my house to install it within 20 minutes of me initially calling. The person that installed the light was very professional and quick. I will definitely be using this company again for my electrical needs."

Generator Install questions, answered by experts

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.
