"We had Henderson Electric hook up the electrical for our new hot tub. They installed the proper breakers, ran conduit/wiring through the attic, to the outside wall, underground to a post, then mounted a switch panel and completed wiring to the hot tub. Can't say enough good things about our experience. Excellent quality of work overall. Very clean and complete professional work. Also very good communication and follow up, which, unfortunately, is not all that common these days. Classic example of doing it right or don't do it, which we really appreciated. We also appreciated the knowledge and expertise as we knew what we wanted done, but not necessarily the best way to accomplish what we needed. They helped us explore and weigh out several options for different ways to do the job, and explained pros and cons of each option. Gave us an estimate the next day and got us on the schedule right away. We had contacted other contractors/electricians and got a few other estimates, some more expensive, some less, but none of them gave us the level of personal service and professionalism like Henderson's. Would absolutely recommend Henderson's to anyone looking to get any home electrical work done."

"John happened to be in town when I placed my request. He was at my house in less than 10 minutes and in under an hour had my electrical outlets fixed. John is super personable and knew exactly what the issue was. I am so excited to put out my deck lights now! I will be contacting you for any future needs!"

"Bart knows what he is doing. He located the problem after some troubleshooting which was impressive, considering the number of areas the problem could have been. Once he did that, he made the necessary repairs. After the repairs, he checked some switches on the panel with breakers built in for testing each respective switch, and found two out of the 3 switches did not test and were defective. He just could have packed up and gone home. It was late at night, and he had had a long day. But he went the extra mile, tested these switches, and advised I get all three changed out. He immediately told me these switches were a little pricey, but he recommended they be changed. I asked him to order them, and let me know when they were in. Bart is the real deal. His cost per hour is EXTREMELY reasonable; much more so than one local big electrical repair company in Idaho Falls I used to call. He will get all of my business in the future."

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.

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.
