"John was very accommodating and understood exactly what we needed. He was prompt, courteous, and kept me informed throughout the process, as the work was done for my mother while I wasn't there. My mom was very pleased with her ceiling fan light fixture installation and the price was very reasonable. I would definitely call him again for any other job I need done. Thanks again John!"

"After putting in a request on Home Advisor, Mike responded very quickly. I advised him i wanted to install a transfer switch for a generator and he went through the steps of what would need to be done. He asked a few questions, asked for a picture of the junction box, and then gave me a very reasonable quote. The day of the install, he called to reconfirm our appointment. The install was quick and clean."

"The electrician clearly explained what he was doing and why. He did not do anything additional until he had my approval. He also pointed out a rigged outlet fixture for a generator and identified it as dangerous and asked if he could remove it. We have more work to be done and we will have them back."

"i recently had a tesla charger installed, and i am extremely satisfied with the service. the electrician did an outstanding job he was professional, knowledgeable, and completed the installation much faster than i expected while maintaining excellent quality. the work was clean, efficient, and everything was installed perfectly. on top of that, his pricing was very reasonable compared to other estimates i received. it’s not often you find someone who delivers great workmanship, works efficiently, and offers affordable rates. i highly recommend him to anyone needing electrical work or an ev charger installation."

Generator Install questions, answered by experts

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.

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

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.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
