"I have used them all the time. I never looked for any other company for electric but not anymore after spoke to the lady and can?t help. I have called them on emergency basis. Because my business lights are not turning on for some reason. So I called them they charged me emergency fees of $450 upfront to dispatch the guy from 2hours far from my location. And before he arrived we managed some how to turn on the light. So it was photocell I had just gone bad.. upon arriving we told him the situation n he said yea we will come tomorrow and fix the photocell. For $30 cheap photocell they put and charge me again $500 for them to come out and put photocell. Which is unfair for us that we already paid $450 upfront for emergency and the guy didn?t do anything? but anyways today 5/9/25. I called because somehow the photocell had gone bad again and all my lights are on.. even the weather is clear. So I called then told me oh it was only warranty for 30days. But the installation guy told otherwi"

"Dustin & his crew were PHENOMENAL! In a world where you have to micromanage, check in and hope and pray people show up, Three Ridges is a beacon of hope! We had a catastrophic emergency, where the power was literally ripped from the cabin by a tree. These guys, were prompt, respectful, handled everything from A-Z, permit, power company and even came back to make sure everything thing was reconnected after the power company came out to restore the power. I would give 10 million stars. We will ONLY use 3 Ridges from now on, and we will tell everyone we know. Thank you Three Ridges!"

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.

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.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

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. 

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.
