"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."

"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 FAQs, answered by experts

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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.

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.
