"Excellent. Came and gave me an estimate and that is the price he charged for installing a new dining room light. Very neat, picked up after himself and had great communication skills. Would hire again without reservation. Highly recommend."

"We needed a meter pole for our RV, and Marty's gave us a very reasonable quote, as well as a full detailed estimate of the job to be done. They installed our meter pole exactly to local city/ state codes, and completed it in a very timely manner! We could not have been more pleased with the project outcome!"

"Bob and his crew took care of some electrical problems with our first home purchase. It is a 100-year-old house and had various electrical issues due to both its age and past renovation work that was done poorly. Bobs team did an absolutely fantastic job getting everything sorted out and were open and transparent throughout the process, making it a stress-free process for us and giving me a huge dose of /feel good/ about the safety of the home we are moving into. I am a worrier and a perfectionist by nature, and this being my first home purchase turned those tendencies up to 11. I am sure they wished at times that I would just let them alone so they could get the job done, but all of my questions and concerns were met with open, honest, and kind spirited responses. So on top of the great work, they were just good people. I cannot recommend them highly enough."

"I had a car charger installed and was really happy with the work. He was responsive, showed up when he said he would, and the install came out clean and professional. Everything was explained clearly, the work area was left neat, and the charger works exactly as it should. Definitely someone I?d recommend if you need electrical work done."

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.

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

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.
