Changing the filter is easy It includes loosening the screws that keep the filter cover in place when it is located behind the ventilator or simply removing the filter from the container when it is on the side of the furnace. The old filter will be dirty, so fix a large garbage bag. Used dirty filters can be disposed of along with your regular garbage. After that, install a filter that will fill in the blank space, and mark your calendar for the next change. Hero Heating & Air provides right kind of expertise for all your furnace services.
