Air filters have arrows printed on the sides that indicate in which direction they should be installed. These arrows should point in the direction in which air flows through the system, which is away from the supply ducts and (normally) towards the fan. The most common problem a rear-facing filter will face is simple inefficiency. If your oven is forced to blow air through the non-porous end of a filter, it will take more energy to do so.
The fan will be overworked and you will pay more money for your heating. The same is doubly true for an air conditioner that has several filters to keep outdoor contaminants out of the indoor air. So what happens if the air filter is poorly installed? Air filters are designed to be installed in a certain direction. Installing the air filter backwards can restrict air flow through the air filter, cause the filter structure to fail, and allow dust, dirt and other debris to pass through the filter and accumulate in the evaporator coil.
If the evaporator coil becomes dirty, the system will not operate at optimal efficiency and could clog the condensate discharge pipe and cause the system to fail. The oven filters are designed so that air flows in one direction through the filter medium. That way, the filter does its job of preventing dust from accumulating on the fans and motors inside the oven. While turning the air filter upside down from time to time isn't likely to cause damage to the system, it can cost you money in efficiency.
If a service person installs air filters for you, notice how they are placed and in which direction the arrows point. Air filters have direction arrows to indicate in which direction the air filter should be installed on the return. Most air filters have arrows printed on the sides that act as indicator marks that point to the direction of air flow. Look for an HVAC repair near me and consider repairing and installing furnace filters.
Check the filters every month and replace them when you can no longer see the light coming through the filter. It all starts with understanding how your air conditioning system works and making sure that air filters are properly installed and replaced on a regular basis. If you find an air filter that doesn't have an arrow, check it again, since almost all filters have it. Changing the air filters in your home seems to be an easy task; however, it is something that is easily forgotten.
The next time you change the filter, match the directions of the arrows and that's it, you've changed the air filter correctly. The biggest problem with installing an air filter backwards is that the oven has to work harder to do its job. If you place the filter upside down, the normally collective end of the device will not face the air supply. The normally common end of the equipment will not face the air supply if you install the filter upside down.
If you insert the filter backwards, the result is that air will have more difficulty passing through the filter if you install it the other way around, so the air controller will have to work harder to compensate for the lack of air flow. These filters will last approximately 3 months, however, they can fail and cause the filter frame to bend or even bend in the return box. The air flow arrows must be printed on the side of the air filter to indicate in which direction the filter should be installed.
