"I recently had a generator installed by Emerge Electrical, and I couldn’t be more impressed with the service I received from start to finish. From the initial consultation to the final installation, the team demonstrated professionalism, expertise, and a genuine commitment to customer satisfaction. The technicians arrived promptly and took the time to explain the entire process to me, answering all my questions about generator size, maintenance, and functionality. They worked efficiently and carefully, ensuring that the installation was seamless and met all safety standards. The team also took great care to keep my home clean, laying down protective covers and cleaning up after themselves. What really stood out to me was their attention to detail. They made sure the generator was properly tested and walked me through how to operate it, providing useful tips for maintenance and troubleshooting. The generator itself has been running smoothly ever since, giving me peace of mind during power outages. I highly recommend Emerge Electrical for anyone in need of electrical services or generator installation. Their professionalism, expertise, and exceptional customer service set them apart from others in the industry. They’ve earned my trust, and I won’t hesitate to call them for any future electrical needs."

Generator Install questions, answered by experts

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

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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.
