"We really like the professional job done by Paul, James III and Nate, they answered all our questions and explained everything to our understanding. They are no doubt well-trained in their field and dedicated to the reputation of the company. Kudos to our saleperson Tom, who also happens to be the president. We had on-location visits from 3 companies to have a whole-house generator installed and no doubt picked the best company."

Customers say: Quick response

"Anthony was very attentive to my project on an old building. He sought out a safe and viable solution to change out an old fuse box and relocate with a new breaker box. He was quick with a response to my request, inspection and quickly gave a solution with a quote. Once I accepted, he scheduled my work right away. He was also prompt on the day of installation and did the work professionally and quickly. I recommend A & A Electric and I would even recommend Anthony to my family and friends. - Pastor Jeff"

"Marlock Electric upgraded our electric service from 100 amp to 200 amp. We were installing solar panels with our new roof, and did this upgrade along with that project. Marlock was recommended to us by the contractor installing the solar panels as a company that would do a very professional job for us - they wanted to be sure the work would be done right to connect the solar system to it. Marlock did an excellent job for us - it was somewhat complicated, but they are experts who knew how to do the work properly. They explained the whole process to us and answered all our questions in a way we could understand. They added extra crew members to make sure the work was done in one day so we wouldn't need to be without electric service overnight. The work was done in a very professional manner, and the site was cleaned up before they departed. We are very satisfied with the service we received from Marlock Electric, and will call on them for any future electrical work we need to have done."

"Mike at MDL electrical went above and beyond the call of duty. We were facing a potential major electrical issue during a very busy evening in the middle of service. He responded to the call and even took the time to stop and check out the issue to ensure our minds were put at ease. He came back the following day promptly and repaired the situation with efficiency and ease. We would highly recommend MDL & Mike and take comfort in knowing we have a reliable electrician to call on! Thank you so much Mike! We appreciate you! Molly & Living Roots Winery Crew"

Generator Install questions, answered by experts

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
