"I had a disappointing experience working with Corey. He did an ok job installing the panel upgrade, but I failed inspection and he ghosted me after asking him to come back to fix it. -He did not realize or inform me each panel upgrade requires a whole house surge protector after 2020 NEC codes, leading me to fail my electrical inspection. -He put in PVC conduits but he did not put in expansion joints according to the electric code, which also lead to another failure in inspection, this was very expensive to fix. -He did not pay the township the permit money that I paid to him, basically robbing me the permit fees. -He stopped responding to text and phone calls after I contacted him after a 2 months of chasing him -I had to hire another electrician out of my own pocket to fix his install. He was affordable at first but it ended up costing me MORE in the long run to fix his conduit install, add surge protector and had to pay the permit fees AGAIN because he didn't pay the town. "

"The best review I could give this company is no review at all, which was what I initially intended. However, my repeated phone calls with requests to speak to a manager have been ignored. So I am turning to the almighty review as my only recourse. We hired Harris to install a new hot water heater and expansion tank. The estimate process was great and I was talked into a "Happy Home Membership". I was told it was $100 a year, but when I received the invoice, it was $119. Okay, not a big deal. But I did have to ask twice for the invoice. On the morning of installation day, I took our dog to day camp early and rushed home. Start time was 9am. No one arrived or called. At 10am I called the main number. I was told it appeared our tech was "just getting his day started". Really??? I was put through to dispatch for an ETA. No one answered. By 11am, with still no word from anyone, I called again. I was told our tech had called out a short time ago. At this point I was angry and frustrated and"

Generator Install questions, answered by experts

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

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.

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

The cost to install a whole-house generator averages at $5,200, but costs can range from $1,500 to $8,900, depending on the type and size of the generator, and the labor required to install it. To find the best deal while still ensuring the unit meets all the needs of your household, hire an electrician to calculate the electrical load of your must-have appliances and electronics beforehand so you don’t pay for more power than you need. As always, be sure to get at least three quotes to find the ideal fit for your needs and budget.
