"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 !"

"Alex was excellent. Installed a plug for a generator and interlock switch on panel. Also installed a couple outlets. Was very friendly and did a great job and is very reasonably priced. Will definitely use him again for all my electrical needs."

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.

"I regularly and highly recommend Don's Electric to anyone who is looking for top-notch electricians and outstanding people to work with. Don's Electric is a well-run company that provides superb service. The Gabbard family is the best! For example, last week we had a lengthy power outage, and (through no fault whatsoever of Don’s Electric) the engine in our back-up generator died, requiring replacement. With no replacement engine immediately available, Don's Electric was quick to the rescue; within a few hours, the Gabbards had installed a portable generator for use during the balance of the outage. (By the way, Don’s Electric previously replaced my outdated electrical service promptly, professionally, and at a very competitive price.) Thank you, Don's Electric!"

Generator Install questions, answered by experts

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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.

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 you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.
