What Happens When an HVAC Filter is Installed Backwards?

When an oven filter is placed upside down, the fibers cannot do their job properly. This means that your oven has to work harder to generate the same airflow, resulting in increased energy costs. Particles are also allowed to accumulate unevenly, causing the oven to work even harder to extract air. The biggest damage that can result from a filter installed upside down is that it can damage your HVAC system and reduce its lifespan.

An AC filter installed upside down will greatly slow down airflow, your oven will have more difficulty operating. When efficiency decreases, the likelihood of a system failure, such as a refrigerant line leak or a failed compressor, increases. The most common problem you'll face with a rear-facing filter is simple inefficiency. If the oven is forced to blow air through the non-porous end of a filter, more energy will be needed to do so. The blower will overwork and pay more money for your heating.

The same goes doubly with an air conditioner that has several filters in place to keep outside contaminants out of the indoor air. The most common problem you will have if you have an improperly installed filter is decreased efficiency. Since the filter is designed to be efficient when installed in one way only, installing it incorrectly will make your system inefficient. One side of the filter is more porous to allow more air to flow freely. Therefore, when installing a filter backwards it would mean that your oven has to work harder to get the results you want.

This will result in higher utility bills and may cause damage to your oven. You won't feel the effects of this at first, but this inefficiency can build up and lead to furnace system breakage and further repairs. So what happens if the air filter is improperly installed? Air filters are built to be installed in a certain direction. Installing the air filter backwards can restrict airflow through the air cleaner, cause the filter structure to fail, and allow dust, dirt, and other debris to pass through the filter and accumulate on the evaporator coil. If the evaporator coil becomes dirty, the system will not operate at optimal efficiency and could clog the condensate discharge line and cause the system to fail. If you have a ceiling or wall air return that uses a filter, the filter arrow will point to the ceiling or wall.

By installing the filter upside down, air will have more difficulty flowing through the filter and your air handler will have to work harder to compensate for the loss of airflow. Under the exhaust pressure of the blower fan, these filter structures will eventually fail over time, causing the cardboard filter frame to bend or even bend in the return box. This is because a dirty, clogged air filter will significantly impair the efficiency of your oven and air conditioner. An air cleaner or air purifier is a device that can be used with your HVAC system that helps remove contaminants from the air in. The intake air moves downward, so the filter will be located at the top, in the upper blower compartment.

If you remember that the arrow should always point towards the oven heating compartment, you don't have to worry about which way to install the filter or which side of the filter goes up or down. If there is no instruction sheet, the filter itself would have arrow indicators to indicate the direction of airflow. It all starts with understanding how your HVAC system works and making sure your air filters are properly installed and replaced on a regular basis. When the filter is installed upside down and starts to prevent air flow, air may begin to circulate around the cardboard frame of the filter, which is not that difficult to do. When installing the filter incorrectly, the system that removes dust and other particles that accumulate will not work.

Also, if you look at where the filter is located, the air comes from the side of the duct where there is no HVAC component. If you have any questions about the air flow direction of an air filter, or if you want a cooling system repaired or installed in your home, contact Hyde's, your Coachella Valley air conditioning contractor. When you install an oven filter upside down, there is no uniform distribution of dust throughout its 1-inch material. This allows it to effectively trap particles in while minimizing deceleration of airflow through your system. When your blower draws in air it passes over this device removing dirt dust pet dander pollen and other particles that can eventually damage your oven. It's important for homeowners to understand how their HVAC systems work and make sure their filters are properly installed and replaced regularly.
