"Electrical & Security Solutions are the best! I have needed their services more than once to replace lights, a ceiling fan and also to install a new electrical box and breaker for our garbage disposal. Tyler promptly responded every time I called and he and Casey are both friendly, efficient and skillful. Aside from the excellent service, the qualities I appreciate the most is honesty for what work needs to be done and how Tyler is also very budget consciousness."

"The amount of work that needed to be done to our 1880 house was extensive. Joe listened to our needs and concerns and offered suggestions that improved our plans. His quote was very fair. He is easy to talk to, professional and honest. Caleb and Dylan who did the work were amazing to deal with. They were very knowledgable, worked hard, and were careful and patient dealing with the oddities of an old house. I highly recommend this company and will call on them for all my electrical needs."

Generator Install FAQs, answered by experts

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

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 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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

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.
