Replacing AC (air conditioner) filter is one of the routine AC maintenance practices, but being routine doesn't make it easy; there are still mistakes that people make when changing filters. Here are some of those mistakes, and how they may affect your AC's operations:

The Filter Is the Wrong Size

There are two main reasons why installing an air filter of the wrong size may hamper your AC's efficiency. First, a filter of the wrong size may not fit as perfectly as a filter of the right size would. For example, a small filter may leave spaces through which unfiltered air may pass and clog your AC system. Secondly, if the air filter is bigger than the specified size, you may be tempted to bend it so that it can fit, which may interfere with its integrity. In fact, an improperly inserted filter may even break or get sucked into the blower fan, causing physical damage.

The Filter Has Been Incorrectly Inserted

Even if you have a filter of the right size, it may not be of much use to you if you insert it the wrong way. Yes, there is a right way and wrong way of inserting an air filter. This is because the filter is designed in such a way that it favors airflow in a particular direction. This is done to ensure that the filter traps the maximum possible debris if it is inserted in the right way. Thus, if you insert the filter the wrong way, it will hamper air flow into the AC system, and your house may not be as cool as it should be.

The Filter Has the Wrong MERV Rating

The MERV (Minimum Efficiency Reporting Value) rating indicates the minimum size of particles that the filter can efficiently block from entering the system. A filter with a high MERV rating is good because it keeps many air particles out – but it is only good up to a point. This is because the MERV rating corresponds to the sizes of the holes on the filter mesh, and each AC has a limit on the mesh sizes it can handle. Therefore, if you choose an extremely fine mesh that your AC system cannot handle, the AC may not have adequate energy to pull the air through, and this may interfere with the efficiency of the system or even damage it.

If your AC has experienced a fall in efficiency after filter replacement, it might be that you made an error with the filter. Consult an AC technician to diagnose the issue and fix it and even advise you on how to avoid the mistake in the future. For more information, contact a company like Plisko Service Solutions.
