The size of the generator you need depends on what you plan to power in the event of an electricity outage. It's essential to understand that when discussing generators, "size" refers to the generator's electrical capacity, not its physical dimensions. For instance, if you want to run your air conditioner, refrigerator, and one television simultaneously, you can determine the required electrical capacity by adding up the total wattage of each device. The most effective way to identify the appropriate generator size for your home is to have an experienced electrician from Keep Smiling Plumbing, Electric, Heating & Cooling evaluate your home and discuss your electrical requirements. They can then recommend a suitable generator and provide an estimate for the total cost, including installation.
