Are Whole House Generators Worth It

A whole house generator is a machine that is connected to the electrical wiring of your home and automatically senses when there is a power outage, and automatically turns on and provides the house with electricity until the power comes back. Power outages that last for some time or a few hours are not a major problem at all. The inconvenience starts when there is a major environmental change such as a storm or a monsoon rain that might last for days.

Yes the whole house generators are worth it because, in case of a power outage, food in the refrigerator can get spoiled, mold growth, no or scarce water supply, lost internet connection, etc and much more you have to face. Extended power outages in the winter can even be scarier. So in such cases, this generator proves not to be a luxury but a necessity to fulfill your power needs.

Apart from being an add-on or temporary power source that will restore your house power during any power outage from the grid, these will also increase the value of your property.

Why Buy Whole House Generators?

Are Whole House Generators Worth It

There are many reasons to buy a whole house generator. I mentioned some of them to help you decide whether to purchase whole house generators or not.


These generators are much quieter than they used to be and can be installed outside, preventing your inner house from polluting your house with noise.


Installation of these generators is only for once and you may not require it to move here and there to make it functional.

It offers fewer installation costs. And it’s for a lifetime.


Larger homes need more electricity and to meet that need a big generator is required with a larger output. So such generators are a perfect fit for larger houses.


A standby generator is an expensive item and should be seen as an investment in your home because it is a permanent fixture. The cost you pay for fuel is radiating and while using ordinary generators you have to first start the generator using manual procedures so this isn’t the case with these generators. You don’t have to worry about starting and cutting off your generator once it is installed it is ready to use after that.

Power for longer periods

Using ordinary generators can not provide power for weeks or consecutive longer periods. For power outages of weeks or months, these generators are best suited. And must be opted in such cases.
