How much is a whole house generator?

In severe weather like a thunderstorm, a power cut usually happens. So, a whole house generator is a must-have device. Because, it can power your entire home in case of a power cut. But do you know how much it costs? The cost of a whole house generator is not only its real cost. It also includes the installation cost and the maintenance and repair cost. Let's check out together.

The real cost of a whole house generator

On average, a fuel-based whole house generator can cost around $1,000 to $6,000. Some generators can cost over $10,000. Many factors can determine the cost of a whole house generator. But the main factor is its capacity.

Capacity is the amount of electricity the generator can produce in a fixed amount of time. You should buy a generator with proper capacity with your electrical devices. The higher the capacity of the generator, the more expensive it is. So, you should estimate your electricity needs to choose a suitable generator.

In general, a large home will need a larger capacity generator than a small home. But you should make some calculations to know the exact total amount of power needs. First, you have to know the amount of power each appliance will take to start up. Then add them up and use this total amount to find a proper generator.

The installation cost of a whole house generator

Installation cost is another cost you have to consider when buying a whole house generator. You can't install a whole house generator yourself unless you're an electrician. 

The different generators will have different installation costs. But the installation cost is usually about ¾ of the generator's real cost. That means with a $10,000 generator. You may have to pay up to $7,500 for its installation. 

That's not including the case of upgrading your electrical system. Sometimes, to ensure the generator's performance, the electrician has to make some upgrades. And this may cost you a great deal. 

If you are a professional electrician, you can install the generator yourself. This can save you a lot of money. If not, don't try it because it is very dangerous.

The maintenance and repair cost of a whole house generator

The cost of a whole house generator also includes its maintenance and repair costs. This cost is not as much as the generator cost and installation cost. But it is still quite a great expense.

After installing a whole generator, you have to maintain it. If you leave it inactive for a long time, it may not run properly. Thus, you will have to run it at least once a week. It will cost you about $5 for the fuel each time. 

Each year you have to pay about $260 for generator maintenance. This cost doesn't include fuel costs during power outages. 

Besides, the generator needs intensive inspection and maintenance every 6 to 12 months. You will have to hire a qualified technician to do this. The cost can be between $65 to $85 per hour. If the generator needs any repair, you have to pay more. On average, a minor repair will cost from $75 to $300.
