"We really like the professional job done by Paul, James III and Nate, they answered all our questions and explained everything to our understanding. They are no doubt well-trained in their field and dedicated to the reputation of the company. Kudos to our saleperson Tom, who also happens to be the president. We had on-location visits from 3 companies to have a whole-house generator installed and no doubt picked the best company."

"Mike went above and beyond for me today. I need the generator for medical and respiratory equipment and Mike rearranged his schedule to get the generator running today! Very knowledgeable, and someone I immediately trusted and felt blessed by the introduction and service he provided to me and my family. I would strongly, recommend Reliable Power Systems and will certainly continue to call on them."

Generator Install questions, answered by experts

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
