"Ollie’s Electric LLC did all of the electrical work on my lake home remodel. Tracy was very professional from start to finish and was always happy to answer any questions during the project . I am very satisfied with the outcome of the work performed. His attention to detail and taking the extra time to ensure the job was done correctly is what separates this company from the others. I would highly recommend to any home owner!"

"The electricians and plumbers were very professional in their demeanor. They worked as a team, everyone knew what to do and how to do it. They answered all my questions, but didn't let that distract them from their job. I was impressed with the speed of the installation. They cleaned up after themselves and took their trash with them."

"What a great team! They helped us feel comfortable throughout the entire process. From the incredible information regarding your location, size of system, installation, and financing. They met and exceeded our needs at a very competitive price with great service. Nathan, Francisco, and their crew were fantastic to work with. Nathan went above and beyond fantastic service. Great communication and assurance that the job is done right! I should also mention that if you are interested in solar, please move quickly, as the tax credits will end at the end of 2025."

"Chip and the crew immediately called me when I requested a quote and came out the next day. Chip took down notes on everything I wanted done or had concerns with, gave me an estimated cost, told me about how long it would take and said they'd be there in the morning. The following day they were here as promised and began working. Every item on my list was completed and even though it took a bit longer due to previous wiring problems, they made sure to stay until they corrected the issues and were able to finish up their work. Dependable, easy to work with, offers multiple options for what you need done, and did exactly what they said they would. Will definitely call again if needed!"

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two.
