There are questions you need to ask before you buy a generator. How do I know what size to buy? How do I know if I buy one too big? Or if I buy one too small? There are questions that need to be answered before you purchase a generator.

Some factors you need to consider are as follows:

Size of generator to fit the load

Time of Use

Gas availability

Natural gas has the best advantage for a generator. If you don't have natural gas, you can pursue propane. This propane tank can be buried in the ground so it is out of your visual site. You can get up to 1000 gallon tank that could last up to two weeks depending upon the size of the generator and usage.

Most power outages occur between five to seven days. Hurricane Katrina was an exception. Most people were out of power for at least one month, most longer. Keep that in mind before purchasing a generator.

If you purchase a generator too small, you won't be able to run your central air conditioning. If you purchase one too big, you will be burning excess fuel for no reason. You may be over sizing yourself. Your fuel consumption will be higher than it needs to be.

A customer called last week to get a quote on a large generator he thought he needed. I gave him what he asked for but I suggested that I come out to his home to see exactly what his needs were. He may not need that large a generator for his house. Remember a larger generator will burn too much fuel and cost you money.

Before purchasing a generator, I suggest you consult and expert. This expert should be someone trained in the area to give you the most efficient generator you can possibly get. Your electrician will take load calculations on your house. Sizing is important. Don't size yourself. Leave that to the experts! They may save you money.
