"Sweetwater Electric installed my Generac whole house generator. Part way through the installation, we discovered a problem with the landscaping and placement of the generator. Sweetwater was patient while we worked out the issue and resumed work the day after the landscaper left. Alan and Thomas worked well together as a team and finished the installation without a problem. I would highly recommend them for your Generac, or general electrical, work. They are conscientious, hardworking, amenable and clean up after the job is complete. What more could you ask for?"

"The Mr Electric Technician could have taken advantage of me, by not showing me that I had missed the final step of fixing the problem myself. He could have charged me around $400 to install a new lighting system & wall-switch. Instead he just showed me how to finish up, said goodbye, and refused payment for coming out. That is TOP-NOTCH-SERVICE !"

Customers say: Quick response

I like to think of my self as the best problem solver around. I'm sure there's a million ways to get the job done. But I only want to make sure its done right, The first time.\nI've been doing maintainece repairs for about 2 and half years now. I started off on my own path a couple of weeks ago and I've been off to what seems like a great start. I would be more than willing to see what kinda project you have to throw at this novice repair man.

Generator Install questions, answered by experts

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.

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.

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.

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.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
