"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

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

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.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.
