Generators make an important line of defense against natural disasters and power outages. With a generator, you don’t have to worry about keeping the food in your refrigerator cold, or powering your heating system when the temperatures drop. When installing a new generator, it’s important to select one that is the right size for your home. By size, we mean the power it’s capable of creating, not the physical size (though that can enter into the equation depending on where you plan to put it). In Lynnwood WA, electrical repair services can often advise you on how to size the right generator for your home, but it pays to know the basic before you give them a call.

The first step is to perform an energy audit for your home, determining how much power each appliance or electrical device uses, and then prioritizing them for use during an emergency. Medical devices usually come first on the list, followed by refrigerators and freezers which store your food. Next is your home HVAC system, followed by the lights in your home. Computers, radios and entertainment systems are usually on the bottom of the list: useful for keeping connected with the outside world, but otherwise non-essential in an emergency.

Once you have that list, you can determine two things: how much power is required to run your whole house and how much power is required to run the bare essentials during an emergency. The former number is preferable and if you can afford a generator of that size, then you should probably purchase it. The latter is less ideal but can do in a pinch if you’re on a budget and still want to keep your household running when the power goes out. In that case you need to carefully monitor which appliances are hooked up to the generator so you don’t overload it when the time comes.
