Installing a furnace filter upside down can have serious consequences for your HVAC system. The fibers in the filter will not be able to properly filter the air, leading to damage to the unit and decreased air flow. This can cause the system to work harder and consume more energy, leading to an increased risk of system failure and higher utility bills. When installing a furnace filter, it is important to make sure that the arrows on the filter point towards the fan motor.
This ensures that air is able to flow through the filter in the correct direction, allowing for an even distribution of dust throughout the filter material. If the filter is installed upside down, it will not be able to capture dust particles as effectively, leading to poor indoor air quality and an increased risk of mold problems. The most common problem that an upside-down furnace filter will cause is simple inefficiency. The fan will be overworked and you will pay more money for your heating.
This is because the oven has to work harder to blow air through the non-porous end of a filter, requiring more energy than usual. The biggest damage that can result from a filter installed backwards is that it can damage the HVAC system and reduce its life expectancy. This is because the oven has to work harder to generate the same air flow, which translates into increased energy costs and additional wear and tear on your HVAC system. It is important to check your furnace filters every month and change them when you can no longer see light coming through them.
If you have any questions about the air flow direction of your furnace filter or if you want to have a cooling system repaired or installed in your home, contact a professional HVAC contractor for assistance.
