Many people don't think much about their air conditioning unit except to push the temperature control a little lower when they're hot or higher when they're too cool. Aside from that, the air conditioner is rarely thought about. Unfortunately, with actions such as these, the unit will be more prone to break-downs and the expense of running the unit will be greater than it has to be. With a little extra care the unit will work better and cost less to run.
The air conditioning filter can be considered the first line of defense for the unit. When air is pulled into the unit to be cooled, dust, debris, pet dander and pollen are just a few of the particles floating in the air. As the air is pulled in, the filter's job is to catch these particles. Of course, when the air filter does a good job stopping these particles, it can get dirty and clogged quite often. When it's clogged, very little air can get into the unit, essentially suffocating it. This makes the air conditioner work much harder than it should, thus causing potential malfunction of the unit. Likewise, when the unit struggles for air, it uses much more energy to cool the area, thus costing more in energy costs.
It's recommended to change air conditioner filters as soon as they are dirty. Pleated Air Filters should be checked at least once a month, and most likely changed if the AC unit has been used frequently. Without much dust and debris buildup, the air filter can often go up to three months before changing the Air Filters, though it's recommended that it be inspected monthly. Homes with animals usually need to change the filter more often due to hair, dirt and pet dander.
For commercial settings, Industrial Air Filters
are primarily used. They have a higher MERV rating than the average home filter. The MERV rating is determined by the size particles the filter effectively stops. It's usually not suggested to use high industrial MERV rated filters in residential settings, as they clog much more often, thus making the home AC unit work harder.
Some air conditioning units have Washable Air Filters
. Using a filter such as this is a convenient and economical way to ensure the filter is cleaned frequently. There is no cost involved in replacement filters. Just take it out when it begins to show a build-up of dust and debris and wash it away. Always ensure the filter is completely dry before returning to the unit.
It really doesn't matter what kind of air filter is used, but it must be changed frequently
. This action will help keep the unit running smoothly and it will make it much more energy efficient.
