"Terrific job. Mock Electric installed a power line on an independent circuit for a new electric fireplace located about 100 feet away from our fuse box. They were on time and did the work in a thorough and efficient manner and on budget. Thank you for this recommendation!"

"The owner, David Smith, was able to schedule my job in a reasonable timeframe and kept me informed when an emergency delayed his arrival. He is very professional and knowledgeable, with a pleasant personality that made him easy to work with. He removed and replaced my foyer light fixture quickly and very carefully. His price for the job was quite fair and the 10% new customer/military discount was nice. I would certainly call on him for any future electrical work."

Generator Install questions, answered by experts

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.

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.
