"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."

"Outstanding service from start to finish! I couldn’t be happier with the job this company did installing our TV mount above the fireplace. From the moment they arrived, everything was handled with professionalism, precision, and care. The installation was fast, incredibly clean, and extremely efficient, no mess left behind and every detail thoughtfully executed. They clearly know what they’re doing and took the time to make sure the TV was perfectly centered, secure, and positioned for the best viewing experience. The final result looks sleek, polished, and exactly what I had envisioned. If you’re looking for a team that delivers top-tier workmanship, respects your home, and exceeds expectations, look no further. Highly recommend and would absolutely use them again!"

"I was impressed how quickly they contacted me to discuss my project, within in minutes I had someone schedule to come and look at the site and discuss what we needed. One week later there were at my house replacing the generator. The tech arrives on time and provide on-going update on the process. They left the project site so clean you would never know I have any work done in the area. I would highly recommend."

Generator Install questions, answered by experts

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

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.
