"Glen and his team were prompt and professional during both installation and annual maintenance. We lost power during the last hurricane and the generator worked perfectly. Pricing was very good and Glen was even able to get me an extended warranty (promo from Generac). I would recommend Green Sun."

In 1993, Tom Raynor began taking on electrical construction and service jobs across southern New Jersey. With just one assistant and one beat-up truck, Tom crisscrossed the state, building a reputation for his small outfit as one that offered professional, hands-on service and reliable, high-quality results. By 1994, it was official—Raynor Services was born! \n\nSince then, that red pick-up has been upgraded to a fleet of ten fully stocked trucks. We are now a “one-stop shop” service company, specializing in electric, heating, cooling, and generator services. Raynor Services has never lost the spirit of professional, hands-on service that it was founded on. Family-owned and operated, we combine small-business service with big-business expertise. \n\nRaynor technicians are among the best in the industry. Each must complete a rigorous hiring process – including a background check, a drug test, and an HVAC or electrical proficiency examination.

"He installed this generator, worked flawlessly in the most recent power outage, and the install process was efficient and clean. From the permit process to the install and price, everything was on point, and everything was as described. If I could I?d leave 10 out of 5 stars. Highly reccomend and will be using him in the future for my next projects."

"These guys are great - had a couple of issues and they immediately helped without question; including come to change a manufacturer's defect long after the job was completed at no additional charge. I will be hiring them for any future electrical projects and recommend you do the same!"

"Revolution Electric updated and reworked all our electric for our 100 year old home remodel. We still had knob and tubes under our plaster walls. They modernized all of our electric from timed lighting indoors and out, full WiFi and boosters, generator installation and even buried our electric lines outside. They are professional, timely, courteous and so easy to work with. They stayed on budget, patiently helped me find cost effective solutions and fully trained me on how to manage all of the systems we installed. I fully would recommend them and rate them a 10 out of 10."

"Scott s Electrical company did an amazing job. I had them put in a whole home standby generator and was very particular on how I wanted the generator to be placed/installed including wiring underground. Scott was very thorough in his work that even the inspectors complimented all the wiring. Customer service was top notch. They were always available to answer any questions and did all the legwork for acquiring permits and just made it absolutely seamless for me (the homeowner). I truly loved working with these guys as I know nothing about this stuff and all I care about is making sure my family is safe in case of a power outage which happens quite often near us. After the install, Scott walked through the generator with both my wife and I and also simulated a power outage to show us how the generator kicks on and made sure everything works that we purchased the generator for. I would definitely recommend this business to my family/friends. Genuine people who love what they do and take pride in their work."

Generator Install questions, answered by experts

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.

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

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