![]() Since the old filter is full of dirt, dust and pollen, don’t just throw it in your garbage. If you remember that the arrow should always point toward the heating compartment of the furnace you won’t need to worry about which way to install the filter or which side of the filter goes up or down. Reminder: The arrow on the filter always points in the direction that the air flows through the unit. The arrow points in the direction the air is flowing. The filter will generally slide into a rack or slot. It will be located on the side that draws in the cold air. Most horizontal furnaces will have a slide-in filter inside the unit. Here is a video on changing a filter in an upflow furnace.Ī horizontal furnace draws air in on one side, warms it or removes heat from it to cool it, and blows the treated air into the ductwork on the opposite side. Which side goes up? The arrow should be pointing up. With an upflow furnace, the filter will be located near the bottom of the unit in the blower compartment next to the cold air return. Furnaces in the basement are upflow furnaces. Upflow FurnaceĪn upflow furnace is installed in an upright position, taller than it is wide, and takes in air through the side or bottom of the unit, warms it in the heat exchanger, and then blows it upward into the ductwork of your home. But in all types of furnaces, the filter is always located near the intake air blower fan and positioned so that the air flows through the filter. There are three basic types of furnaces, and the filter is located in different places depending on the furnace. Locating the Filter and Filter Direction Tips ![]() A sensor in the furnace gets overheated, and a switch shuts down the furnace to prevent major damage. The reduced airflow caused by the backwards filter isn’t letting out the heat. Is your furnace acting funky after filter change? Specifically, does it turn off before the temperature you set the thermostat to is reached? You want it 74, but it keeps shutting down and the house is 72? This is called short cycling. The most common problem if the filter is backwards is reduced airflow, which can lead to poor efficiency and higher energy costs or equipment that works harder than it should and breaks. Maybe nothing bad – or maybe something expensive! What Happens If You Put a Furnace Filter In Backwards? If air filter direction is still unclear, read on.We’ll “start from scratch,” and explain everything including which direction an air filter goes in each common type of heating and air conditioning system. Within a few seconds of the blower starting, you should be able to feel which direction the air is going by putting your hand, a few fingers or even a slip of paper (hang onto it tightly) into the place the filter goes.Then, with the filter removed, not in the furnace, turn on the blower by choosing the Fan option of the thermostat and setting it to the On position.Turn the filter around until you find the arrow.In a downflow furnace – yes, the arrow should point down.Įvery furnace filter frame has a printed direction arrow on the side of it. In an upflow furnace, the arrow should point up. For example, if air is flowing from the left to right, then the arrow points right. It’s one thing to say the arrow should “go with the flow,” by pointing in the direction that air is moving. Quick Way to Find Air Flow Direction in a Furnace or Air Handler The furnace filter, aka air filter, should be placed so that the arrow points in the direction air is flowing within the air handler, furnace and/or ductwork.
