Generator Buyer’s Guide

If you are in the market for a generator, there are many factors to consider before making a purchase. There is no “one size fits all” when it comes to generators and we want to make sure that you know what questions to ask and what you should be looking for before purchasing one.

What type of power outage do I need a generator to cover?

Generators should be used to power a home during a short term outage. If you live in an area that is prone to long term outages or regular loss of electricity, then a generator may not make sense for your needs.

The best way to determine this would be by contacting your local utility company and ask what the average time between interruptions is as well as the longest interruption they have experienced over the last five years.

In addition, you can check with them about how often it has been necessary for them to bring in crews from other areas because their own service territory cannot handle all of their customers’ requests. Also consider whether there are large corporations nearby which will need emergency backup power if they lose commercial power or even worse – completely go off the grid.

By asking these questions, you will get a good idea of which type of generator to buy and what size would be best for your family’s needs.

What type of fuel will the generator take?

Not all generators use the same type of fuel. There are several different types that you can choose from and each one has its own benefits as well as drawbacks.

The three most common types of fuel used in generators today are propane, natural gas, and gasoline.

Generators are an investment and they should be treated as such – with the same type of respect that you would give your most valued piece of equipment at home or work.

Before buying a generator, make sure to do some research on which fuel source best meets your needs and whether it is available in your area before making any final decisions about which unit will suit you best for backup power during outages.


Propane produces clean power but it is slightly more expensive than gasoline or natural gas. It also requires a tank which will need to be refilled periodically so there is some additional maintenance involved with this option over others. Propane tanks can range anywhere between $100-$150 depending on size so they do add to the cost factor for this generator style compared to other options out there . Another drawback would be if your home runs on propane heating then you may not be able to rely on this as a backup power source because the two systems use similar fuel sources so you would have to convert your heating system over from propane.

Natural Gas

Natural gas is also an excellent option and it typically requires less maintenance than both gasoline or propane generators. It does not produce any harmful emissions which makes it a great choice for those who are environmentally conscious, but remember that natural gas lines must be present in order to connect up with this generator style. If they’re not already there then installation will require professional help – which means more time and money out of pocket. In addition, if you choose this route then check into what type of service agreement your utility company offers when things go wrong after business hours since many companies charge a fee to come out and turn on your natural gas service if it’s been turned off.


Gasoline is the least expensive option available but it also requires more maintenance than other types of generators because you will be required to add oil, check the fuel levels regularly , run the generator dry before long term storage and make sure that all gasoline lines are completely drained . In addition, you need to know about any local regulations concerning noise pollution when utilizing a gasoline powered generator so that you stay in compliance with city ordinances or homeowner association rules. There may also be limits as far as where they’re allowed to be used – possibly just indoors or near open windows and doors.


Electric generators are popular because they tend to be easier to start up, but the cost of purchasing one is much higher than any other option on this list. In addition, you have no control over how long it will run since your electricity service could go down at any moment which would stop them from working completely.

How much wattage does your home require?

The best way to determine this is by adding up the wattage of everything that you want to power during an outage. This includes items like your refrigerator, sump pump , furnace blower motor and any other major appliances or electronics .

Remember that running two loads at once could push you over what your generator can handle so it’s important to prioritize which ones should be powered first if there isn’t enough wattage for all at once.

How long will I need my generator?

This question ties in closely with deciding on a type because each fuel source has different advantages as far as storage goes. For example, propane tanks are portable but they’re also subject to freezing temperatures whereas natural gas does not freeze unless taken directly from the line.

Gasoline can be stored for up to two years, but it must be treated with a stabilizer first which adds on cost and time before use.

Do I have enough space outside where I can store the generator?

This is another major consideration because you need to make sure that there will be enough space for your generator. Make sure that it’s near the house and not too close to any windows or doors, but also keep in mind how long of a power cord (if using electric) would be needed so it reaches where you want it .
