It can be inconvenient, frightening and even dangerous when the electricity goes out in your home. This is why having a home generator can give you peace of mind. There are a variety of generator options available, and by far one of the most energy efficient units is a home generator that your HVAC technician can install. Unlike portable generators, home generators are meant to be a permanent energy backup in case of an emergency. They run on your home’s supply of natural gas or propane, so you don’t have to worry about refueling. This provides a very energy efficient way of ensuring your home will have power during a storm or other emergency. Additionally, home generators raise the resale value of your property by providing a sought-after amenity.
