Generator Tip: Whole House Generator FAQs

If you are thinking about buying a new whole house generator in Spokane, you probably have a few questions about how to select and install the right model. Here are a few common questions and their answers on this topic:

 What Sizes Are Available for Whole House Generators?

Whole house generators generally come in sizes between 22 and 48 kilowatts. The number of kilowatts you want in a generator depends on the number of amps your home consumes. We know the maximum because no home consumes more than 200 amps due to limits in the electrical grid. A 22 kilowatt generator, for example, would replace 92 amps in your home, more than enough for most days – though probably not enough to keep your air conditioner running through the night.

How Long Does a Generator Last?

A quality whole house generator is often rated for up to 20 years of operation in standby conditions. That means that it will last for 20 years while actively installed on your property. That does not mean it can be operated continuously for 20 years, and operational lifespan will vary by model.

How Much Space Does a Generator Need?

You should allow for at least 3-5 feet on all sides of the generator for ventilation and to ensure nothing can get caught up in the system. It should be in a clear space away from entrances to your home but close enough to be easily wired into your electrical system during installation.

What Maintenance is Required?

The actual maintenance needed will depend largely on how often the system is actively used. Either way, it is recommended that you change the oil and all filters once per year. A full inspection is recommended if the system is used for more than 24 hours consecutively in that time period.
