"Ken was hired to put a sub-panel in the garage, but he notice that rain was getting in the main panel. I hired him to replace the service coming down the side of the house, through the meter box and then the main panel and sub-panel. He did a great job. He was clean and neat and he worked around my work-from-home needs to electricity. He did the service and main panel on a Saturday and I had minimal power disruption. He is friendly and knowledgeable. I would definitely hire him again."

"After buying a new refrigerator, Home Depot told me I needed a plumber to run a new water line to the refrigerator. I was not happy with the Home Depot tech that called me. The plumber, Dave, arrived soon after I called Harris and did a phenomenal job! He was friendly, professional and worked quickly. Thank you, Dave, and Harris Plumbing!!"

Generator Install questions, answered by experts

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
