Why Is There Condensation On My Unit
One of your AC unit’s functions is to get rid of the humidity within your home. To do this, your evaporator coil absorbs the heat and gathers moisture. When this moisture oozes down into the condensate pan, it is removed down into your wastewater plumbing system by a drain and a pump. The evaporator coil’s process of absorbing moisture and humidity in the air is the condensation process. In fact, this is the dripping sound that you hear from within your unit.
When there is so much condensation being processed in the evaporator coil, it is normal that there will be a condensation leakage, especially during scorching hot summer days. Your air-conditioning unit will run persistently in order to sustain your home’s comfortable temperature. And since so much condensation is taking place during hot weather, the collected moisture in the drain pan usually overflows. However, if this leakage continues, it is best to schedule an appointment with HVAC specialist and have your system checked.
Other Problems Related to Leaking Condensation
Aside from your AC’s continuous operation to maintain the cool temperature of your home during hot days, there other causes for the water in your condensate pan to build up. It can be any of the following:
- Mass of bacteria is blocking the drain
- Restricted airflow
- A degrading insulation
Massive Bacteria Growth
Stagnant water can cause bacteria build up within your condensate pan. If there is massive growth of bacteria or mold in your AC unit, it will block your drain. Once it happens, water will start to overflow and spill right into your home. The condensate pan is shallow so any obstruction in the drain can cause the water to easily fill it up and overflow.
Airflow restriction interrupts with the smooth operation of your air conditioning unit. Restricted airflow easily causes your evaporator coils to form ice layers or frozen condensation. This frozen condensation causes a quick buildup of water which then spills over into your entire AC unit from your condensation pan.
So what causes airflow restriction? Dust and dirt formation that gets stuck up in your air filters obstructs your system’s airflow. To avoid this, change your filters more often or clean it as often as needed. Smooth airflow is the key to avoiding any further damages that can result in costly repairs in the future.
Inside your AC unit, there are copper pipes that run the refrigerant. Condensation usually takes place on these copper pipes if it has a degrading insulation. This situation is common in older homes or older air conditioning system. Make sure to have your insulation checked during your seasonal maintenance appointment with your HVAC technician.
Your air conditioning pan or cabinet is not something that you usually inspect. When left unattended, it will lead to extensive damages and even cause health issues. The standing water within your condensate pan increases your home’s humidity. High humidity leads to rapid mold and mildew growth and damages your building interior through the bacterial contaminants. Molds also release toxins into the air which are a hazard to you and your family’s health.
