"John was always professional and quick to respond and answer my questions. For personal reasons, before hiring Barclay Construction, I had to wait a long time to be able to replace my old siding. John and his crew made it worth the wait. All were pleasant and made me feel they were anxious to please me and take pride in their work. In addition to the siding replacement, they painted the trim and doors and installed my window boxes. I am so happy and appreciative of the great work that they did. I can give them my wholehearted recommendation."

"Kent is an excellent person and I would call him and his co-worker for any electrical work. He installed a standby power generator for me and did an outstanding job. During this COVID-19 period he and his employee wore gloves, masks, and booties when required to be inside our home. Can't say enough good about this company!"

"I had used Worry Free Electric in the past and had very good service. I called James Costello again for some outlet relocations, new outlets, and new light fixtures installation/replacement. I was supplying these new light fixtures. I told James what I wanted to achieve, and where I wanted the new outlets and ceiling lighting fixtures located. He made some recommendations and suggestions, did exactly what I wanted and beyond with the addition of some three way switches for the lighting circuits. The whole experience was above my expectations. James Costello will be my first call for any future licensed Electrician project!"

"Jason and his helper established power to a garage and installed outlets and lights that I supplied. The work was of high quality and to applicable standards. He did not skimp on materials — they were from electrical supply house. I would have liked more communications, but he did what he said he would do."

"AJ took very good care of our project. Quick response and excellent timing for installation of new fan in a LR with no electrical fixture in the ceiling. Also replaced a tired bathroom exhaust fan. Really wish we would have done this project a long time ago, the living room ceiling fan is a game changer. Would recommend you check AJ out for your project."

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.

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.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

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.
