Generator Install questions, 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. 

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

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. 

When properly maintained, natural gas generators can last a long time, as much as 20 to 40 years. They have relatively few needs compared to generators with other fuel types. However, the generator’s lifespan ultimately depends on how often the generator is used and for how long it’s left running.

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.
