Changing your HVAC system’s air filters once a month, or as directed by the furnace or filter manufacturer, helps ensure that your system has smooth, uninterrupted air flow.
New filters can help your system work more efficiently, saving you money in the process. For example, routinely replacing filters in your home’s heating and air conditioning system can account for an energy consumption savings of 5 to 15 percent. For a HVAC unit consultation click here.
