"Artie and Greg came to our house multiple times for wiring related to a kitchen renovation. They wired our new kitchen island for an outlet and microwave. They also installed new high-hats and pendants in the kitchen. They were professional, competent, and efficient. They did great work and I would highly recommend them."

"Excellent work as always - this is our third time using Antonio and they always do a great job and clean up! We had a new panel installed with a switch for a new generator that I bought. They also ran a new circuit for my microwave which used to trip the breaker all the time. THANK YOU!"

"Joe Rinaldi and his team are top notch electricians and I highly recommend them for any residential service. I requested the services of AM/PM Electric on two occasions; One service request was for a non working outlet in the master bathroom and the second request was to install three new electrical lines in the garage of my home. Joe and his team did extraordinary work on both jobs. My dedicated 120V and 240V lines in the garage were professionally installed and routed through conduit. The end result was a very clean run with everything installed by code. There was a small mishap where the circuit breaker I requested was out of stock however Joe personally corrected the problem as soon as he could. In my experience, AM/PM is one of the best electrical contractors in Westchester and I highly recommend their service. My interactions with Joe proves to me that he truly cares for his customers and the quality of his work. He worked to make sure that I was fully satisfied. I can't ask for a better contractor in Westchester County, NY. This is an honest review by a new homeowner in Cortlandt Manor, NY."

"TriCat is very professional, clean, and prompt. Angelo is great and knows exactly what needs to be done. Their prices are also fair and comparable to other electricians in my area. The job was done on time. This is very important when trying to keep the renovations on schedule. I would definitely recommend them to a family or friend, and use them again myself."

"Were recommended by my neighbor and architect. We have plaster walls and old electrical in our 1920's house. Every bedroom did not have a ceiling light or a light switch on the wall. Over the years we've had some real unprofessional people "install" a light switch (and light fixture) in a bedroom and leave a our place a wreck.
Conte/A Perfect Goldman didn't leave a mess and were in and out before I knew it. They saw our walls and told us beforehand where they were going to make their cuts. They neatly patched up the holes and I barely noticed anything."

Generator Install questions, answered by experts

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, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

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.

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 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.
