In an air conditioning system, cooling usually takes place in the evaporator coil area. For this process to be efficient, a delicate balance has to be maintained between the rate at which the refrigerant absorbs heat and the amount of warm air that is in the evaporator coil area. This is because if the rate at which the refrigerant absorbs heat is higher than the rate at which warm air moves into the evaporator coil area, coil icing will occur. This will then increase the likelihood of both a drop in air conditioner performance and leaks. Here is what you should know about the relationship between dirty filters and coil icing and how they may be to blame for your system's leaks.
Dirty air filters restrict the rate of airflow within the air conditioning system
Before any air can gain entry into an air conditioning system, it has to pass through the system's filters. This is usually the case to ensure that the system is protected from the negative effects of dirt accumulation such as reduced heat exchange rates in the evaporator coil area. Unfortunately, in the course of protecting the system by trapping dust particles and other debris, the filters can get clogged. This then creates problems in the air conditioning system, since clogged filters can never let in as much air as the system needs. This leads to restricted airflow within the entire air conditioning system.
Reduced rate of airflow causes coil icing
The reduced rate of airflow usually affects the operation of the evaporator coil the most. This is because reduced airflow means that the amount of warm air available in the area will be less than expected. As a result, the evaporating refrigerant's cooling effect will be so extreme that it will be enough to condense air moisture and then freeze it. This then causes coil icing.
Coil icing leads to air conditioner water leaks
Since cooling air produces a condensate, manufacturers usually install a condensate drainage system that helps to prevent water leaks. The formed condensate usually collects in a collector tray which then gets drained by condensate drain lines that eventually dump the water outside. Under normal circumstances, the tray can handle the dripping condensate. However, coil icing tends to "collect" the moisture. It then releases it in a flood once environmental temperatures force the ice to melt. This sudden flooding is usually too much for the collector tray to handle. As a result, it overflows, resulting in air conditioner water leaks.
Cleaning helps to reduce water leak incidences
Regularly unclogging your filters with a vacuum cleaner will help to prevent the air starvation that dirty filters usually impose on an air conditioning system. It will help reduce the risks of coil icing, something that will then help protect your property from leak-related property damage.

Hi there, my name is Marissa Sonder. I would like to use my site to talk about the different types of furnaces available for residential and commercial applications. Growing up, my school had an actual boiler room that provided heat and hot water for the entire building. All of the students loved to go down to the boiler room and learn about all of the components down there. Although many buildings have moved on from this old piece of equipment, I would like to discuss its use in detail on this site. I will also talk about modern electric, natural gas, propane and oil furnace systems. Thanks for coming by.
