"Kope Electric just finished installing a Generac generator at my house and their work was top notch. They actually got me in their schedule 1 week early and finished as timely as they said they would. I highly recommend them to anyone interested in a generator."

"Plesh electric did a fantastic job installing our whole house generator. We don’t have natural gas so we had to also had to have a propane tank installed. They did a great job organizing with the propane company and managing the township permits. I highly recommend them."

"Ken and his team from Transform Electric were terrific! Ken immediately contacted me and was able to come and give me an estimate right away. We started the project a few days later. I had four rooms that needed new recessed lighting installed. The team came on time and started working. They were very professional and reliable. They moved all my furniture and covered what was necessary. When it was all done, everything looked great and I was very pleased with the outcome. They also cleaned up after they completed the job. Overall they did a fantastic job and I would definitely recommend them to others!"

"I have no complaints about Mr. Electric. In fact, the technician went above and beyond and was excellent. He couldn't make it on the day of installation, which was unexpected, but his stand in honored his commitments. The only reason to not give 5 stars was that it seemed excessively expensive. I wouldn't pay that again for what it was. I'd do it myself. Even Angi gave me a reasonable quote. They charge six times that reasonable quote for a simple outlet transfer... 10/10 for customer service. I guess you'd have to be though, for all that money."

"My central air quit during a nasty heat wave and they responded quicklyâ within a few hours a technician arrived that evening, followed shortly by the salesman when I decided to replace instead of repair. The job was scheduled for the very next morning! The installers were on time, friendly and cleaned up the areas. Everyone I dealt with was knowledgeable and professional. Interest-free financing was a huge selling point. Very good experience!."

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

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.

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.

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.
