What Happens If You Put A Filter Drier In Backwards

If you put a filter drier in backwards, it won’t work properly. The filter drier is designed to remove moisture from the air, and if it’s installed backwards, it can’t do its job properly. This can lead to problems like reduced air flow, and it can also cause the filter drier to freeze up.

If you’re not sure which way the filter drier should go, consult a professional.

Are filter driers directional?

Yes, filter driers are directional. The inlet and outlet side of the filter drier must be installed in the correct direction in order for the filter drier to work properly. The inlet side of the filter drier is the side that has the larger opening.

The outlet side of the filter drier is the side that has the smaller opening.

What direction should a filter-drier face?

When it comes to HVAC systems, one of the most important parts is the filter-drier. This component is responsible for removing moisture and contaminants from the refrigerant, which helps to keep the system running smoothly and efficiently. But in order for the filter-drier to do its job properly, it needs to be installed in the correct direction.

So, what direction should a filter-drier face? Generally speaking, a filter-drier should be installed so that thearrow on the body of the unit is pointing in the direction of the refrigerant flow. This will ensure that the filter-drier is able to do its job properly and effectively remove moisture and contaminants from the refrigerant.

Of course, there are always exceptions to the rule. In some cases, it may be necessary to install the filter-drier in the opposite direction in order to achieve the desired results.

What are the symptoms of a partially blocked filter-drier?

If your filter-drier is only partially blocked, you may not experience any symptoms at all. However, if the blockage is severe, you may notice your air conditioner or heat pump is not cooling or heating as well as it should. You may also hear strange noises coming from your unit.

If you suspect your filter-drier is partially blocked, it’s important to have a professional HVAC technician inspect and clean your unit.

What causes a filter-drier to clog?

As HVAC systems run, they inevitably begin to collect dirt, dust, and other debris. This debris can clog up a filter-drier, causing the system to run less efficiently and eventually leading to complete system failure. The most common cause of clogged filter-driers is simply dirt and dust buildup.

As air circulates through the HVAC system, it can deposit dirt and dust on the filter-drier. Over time, this buildup can become significant enough to restrict airflow and cause the system to overheat. Another common cause of clogged filter-driers is moisture.

If the filter-drier isn’t properly sealed, moisture can enter the system and cause the filter-drier to rust and degrade. This can also lead to build-up of dirt and dust, as well as mold and mildew growth.


If you put a filter drier in backwards, the air will not be able to flow through it and it will not work properly.
