"We originally hired Precision Electrical Services to fix faulty outlets and fuse box. We were impressed with their communication, professionalism, and quick scheduling that we hired them to install a ventilation / light fixture in our bathroom. I canâ t say enough good things about them and will use them for all of our electrical needs moving forward."

"Came on time. Checked out the electrical problem with our clothes dryer and gave me an estimate. He went right to Home Depot to get new wiring and came right back and fixed the problem. Excellent service and will use him again."

"Derek was very prompt in his response to my initial call. He stopped on the very next day to assess the project and explained in detail his ideas about the electrical set up in the basement. He was asking helpful questions and making sure all details are discussed. His proposal was sent to me in the evening; his quote was very fair and saved me money compared to the quote form another company. Derek came at 7:15 am on both days of installation and worked until 5:30 PM. He finished quite a large project in 2 days and scheduled the township inspection on the next day. The electrical inspector was VERY complementary about Derek's work. A note - he installed a switch for a generator to power 5 house lines. In case of electric outage, the house is equipped with a generator outlet on the outside and a switch inside. Derek explained all the details how to operate it - great job! Highly recommend him."

Customers say: Quick response

"I called Anthony about installing a transfer switch and outside outlet for a portable generator. He returned my call quickly and discussed the job over the phone. I was given a fair price for parts and labor. He arrived on time for the installation and spent 3.5 hours doing meticulous work. He answered all my questions regarding the installation and operation of the equipment that was installed. He even spent time showing me how to properly operate and care for the portable generator. Anthony was professional, friendly and courteous. I highly recommend him for any project."

"Peter did a 100 to 200 Amp electrical service panel upgrade and also installed a power outlet for an EV. He reached out quickly and was very polite and professional. He definitely kept his promise about how meticulous his work would be. He always showed up at the agreed time and inspection passed without any problems. Price was very reasonable. When should you hire Peter? If you are looking for somebody who completes his work as promised with a high quality standard (even if it might take a bit longer). When should you not hire Peter? If you are looking for somebody to rush the job, possibly cutting corners just to be done quickly. Thanks again, very happy!"

Generator Install FAQs, 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.

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
