"Tom did a fabulous job with the whole house plug installation for my back up generator. He was quick and efficient and cleaned up well after the work. He explained how to use the plug and manual interlock and made sure everything worked before leaving. Quality job on all fronts. Pricing was fair and he was able to fit me in on short notice due to another job rescheduling. I will definitely contact him again should the need arise."

"We needed a 240V (level 2) EV charger installed in our garage. Our contractor friend highly recommended Charles. Charles looked at our current electrical panel which is almost 40 years old and had no space to add new circuits. He recommended we replace the panel with a larger one and promptly provided an estimate. We also asked Charles to install a generator inlet connection and an interlock switch for the panel so that the EV battery can be used to provide backup power in case of a power outage. Once we approved the project, Charles gave us a time and duration and he got the job done on schedule. He came back again to rearrange some circuits in the panel so that the EV battery can provide power to the important functions in the house such as kitchen, refrigerator, furnace, den, etc. Overall, we are very pleased with the work done by Charles and we have no hesitation in recommending him."

"I needed a Tesla charger installed in my garage. They showed up to the house quickly, and were very knowledgeable on what to do and what i needed. They installed it within an hour, with very quality parts, and were very neat and tidy about it too. No issues since install! I definitely would consider them again in the future!"

"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."

"I couldn't have asked for a better service person. Alex came for consultation on my electric hot water heater replacement. He quickly diagnosed and fixed the problem and told me my water heater is fine. He is a true professional. He was very kind, pleasant and courteous, and gave me useful information about water heaters and installation issues in general. When my 10-year-old water heater quits for good, I know where to go. Thank you for the great work!"

Generator Install questions, answered by experts

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

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.

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
