"Yes, serviced my Generac and found the oil cap was loose and had been leaking. Fixed it all up and now ready for winter. Also had a burned out wall socket and found the problem right away and fixed it and all the other wall sockets started working. So happy it wasnt a major wiring problem. Very pleasant and polite and kept us informed the whole time."

"He installed the generator and serviced it for $5777.00 and everything was great. We then purchased a new home in January 2017 and he was able to move the generator and reinstall it at our new home for $1,016.00. It went perfectly. They were great people doing a great job because they knew what they were doing. The generator still works and we have had no problems. I would recommend him to everyone."

"I hired Justin to wire a 24x36 building with multiple different type of outlets, lights inside and out, breaker box and pole. He was very knowledgeable and was able to give some ideas that will make things more useful in the building later. He was very reasonably priced. I would highly recommend and will be using him again in the future."

And will continue to gladly call him when needed."

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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.

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.
