"Apex installed a Whole Farm generator for my horse farm. They were very professional when they came to determine the size generator I needed and the quote was quite reasonable. The installation and hook up was completed in a timely manner. I now have peace of mind knowing that in the event of a power outage I can still provide excellent care to my horses. I will certainly be contacting Apex for my future electrical projects."

"I was so impressed at the excellence and professionalism of this company in doing the projects I needed for my remodel. Iâ m learning that surprises are to be expected when doing so, and for a homeowner, what would be daunting for me, was dealt with easily and knowledgeably for Ryan and Kyle. Ryan came back to address an issue stemming from the quality of the fixtures I chose, and helped me to find an adequate solution, with patience and a great attitude, which spoke volumes to me. I am grateful to find professionals that do quality work, and possess integrity, and I would highly recommend Ryan and his crew."

"I spoke to this company over the phone that told them that I was looking for somebody to trace my household telephone lines. I have a short somewhere and I would like to find somebody that could find it and rewire the telephone system to bypass the short. This company does do that type of work and didn't know of anybody that did."

Generator Install questions, answered by experts

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.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.
