"They are incredible!! They are by far the nicest, most conscientious electricians I've ever worked with. They're honest and get the job done. We had a major panel upgrade and they handled the whole thing from planning to permits. They were at our house for the inspection and handled the whole process. Not only that, they were friendly and got back to me right away when I had a question. They then followed up with me when the project was done to make sure all went well and if I needed anything else. These folks are THE BEST!!"

"Totally happy. Just had my Generator hook-up today and everything went well. I would recommend them. Communication was excellent from the time I asked for a quote. They were on time that day for the quote and showed up on time for each faze of the installation. They left the work area as clean as when they found them. Totally Happy."

"Juan is very knowledgeable about electric circuits. He is calm, friendly and polite and didn't try to take advantage of me. He repaired two 3-way circuits and switches. I will definitely call him again for electrical problems."

Generator Install FAQs, 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. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
