Seeing water leaking from any part of your air conditioner is shocking and can lead to costly repairs if not addressed properly. The main question people have when seeing their air conditioner vent sweating is “what is causing this, and how do I stop it?” There are many different reasons that your AC vent may be leaking water into your home and figuring out the cause can save both time and money. Here, we’ll look at 4 of the main reasons you may see condensation coming from your AC vent.
1. Dirty Air Filters
Not only will a dirty air filter in your air conditioner worsen the quality of air in your home, but it can also cause blockages and other backups causing your AC to leak or not function properly. When the air filter in your AC unit is dirty, the air is not able to pass through as well as it would normally. This can cause the coils to freeze, which not only makes your air conditioner blow less cool air, but once the unit is turned off and the pipes are able to thaw, the water escapes the unit by leaking out.
2. Improper Insulation Around Air Ducts
Proper installation of the insulation around your air ducts and air conditioning vents is imperative to your AC unit’s efficiency, and improper installation can cause many problems besides just leaky AC vents. Unfortunately, most times this is not as easy of a fix. With improper insulation, the main way to fix it is to take out all existing insulation and replace it using more efficient installation techniques.
3. Improper Sizing of Ductwork
Improperly sized or placed ductwork can cause a lack of airflow, which could lead to condensation buildup on the air conditioning vents.
