"Travis came to look at the problem on a Tuesday morning. When I explained to him that lights in the house were flickering he became concerned and put my job on the top of his list. Once he arrived he immediately diagnosed the problem as many of the circuits in the box had deteriorated due to moisture in the line. He fixed the bad circuit in question and showed me the problem and explained that due to the age, oxidation, and rust that I may have future issues with the remaining circuits. I decided to replace the entire circuit panel and circuits as well as have a new meter with new wiring and drip lines installed on the exterior of the house, as the old meter was also corroded and detaching from the siding.. Travis returned early the following day at the exact hour we had agreed upon and worked a full eight hours to complete the entire job. His work is exemplary: very neat and methodical and whenever I had a question he would answer it in detail. His work was completed within the 2 days and came to approximately 10 hours in total. He supplied all the necessary materials and had everything he needed on hand in his truck.. I recommend him very highly as a skilled and experienced electrician located in Berkshire County."

"Paciorek Electric was terrific at getting out to us quickly. MA was slammed with power outages (10/16/19) . Our generator was down (we hadn't had it serviced in years) and they came out right away to do a full service, repair, replaced battery, and spark plugs. We're up and running again. We will use them again for a regular service call when it's due."

"I had an excellent experience with Stephanie, Tim, and Spencer during the installation of my mini split system. From the very beginning, they were professional, friendly and communicative. They took the time to explain how the installation process would work and made sure I understood all the benefits of swtiching to the system. I felt well informed and supported. Since the installation, the system has made a huge difference in my hosuehold. The units are quiet, efficient, and give me the ability to control the temperature in all rooms in my household. Not only does it keep the space comftorable by replacing AC's but I've noticed the air quality and drop in my electricity bills are better. I"m grateful for the work this team did and would recommend them toothers. I trust them completely and wouldn't hesitate to use them in the future again. Thank you!"

"One thing I really liked about his work was the attention to detail and he made sure things were done right, not just fast. He goes out of his way to make the installation easy to work on in the future if need be. And it is very neatly done."

Generator Install questions, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

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. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

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.
