"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."

"Colin helped us out with running electricity to our detached garage, and installing a level 2 charger for our cars. His work was excellent and efficient. He was communicative before, during, and after the project, and he was on time each day. His initial bid was very competitive, and we're super glad that we chose Colin to work with. We're looking forward to our next project with him."

"Dominic removed old wiring and electric fixtures in my cabin. He installed all new wiring, inside and outside lights, and designated outlets for items like a microwave oven and future hot water heater. My contractor was impressed with the quality of Dominic's electrical rough-in. After the insulation and sheetrock were completed, he returned to add all the fixtures, switchplates, smoke detector, etc. Everything looks great. I've used Dominic a couple of times, and he does a neat, professional job, always responsive to the customer's needs."

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.
