"I hired Rob Heiser to install 7 new light fixtures and a post light on my home's exterior. He also installed a path lighting system and a brush box on the outside of my house to connect outdoor speaker cables to my Sonance system. Rob and his sons did an excellent job and were extremely professional. He performed the job exactly as I asked and did a great job cleaning and organizing all the removed fixtures and trash before they left. I would highly recommend Heiser Electric."

"I reached out to many companies for information on a whole house generator and Sparkie Electric was the first to contact me. They answered my many questions even before they came out to give me an estimate. After recommending which generator would be the best fit for my house, we set a date for the install. Sparkie Electric arrived on time and worked non-stop. I appreciated their efficient, knowledgeable work ethics. All of the men were courteous, friendly and answered all questions or concerns. I have already recommended Sparkie Electric to several of my friends. Not anxious for another power outage but feel confident that should one happen, my generator will 'save the day"!! Give Sparkie Electric a call today!!"

Generator Install questions, answered by experts

Costs range from $500 to $2,500, depending on generator type and installation complexity.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
