Knowing how to take care of your home will help keep the cost of repairs and maintenance low, especially when it comes to your home systems and appliances. If you know a few simple things you do not have to call in a professional. A simple task is knowing when and how to change your furnace filter.

Your furnace is usually located in a basement, hall closet, or garage. However your thermostat is located somewhere in the home, usually in a central location. You may think a furnace is only used during the winter months, because the connotation associated with furnace is ‘heat.’ This is not the case. Your furnace also sends the cool air from a fan or air conditioner throughout the vents in your home.

This means most furnaces run year around, with a few nice days in the spring and fall that they get a break from running. So it is important to know when to replace your air filter to ensure your furnace isn’t working harder than it has to by pushing air through a filthy filter.
