Sweating: What Is It?The moisture that accumulated in the lay-in diffusers and the T-bar grids next to the diffusers appears in the form of sweat. When there’s a problem in the air distribution system of your heating and cooling system, sweating can occur.
Why Worry About HVAC Sweating?For some home and business owners, sweating might seem to be a little annoyance. But, this simple problem might turn out to a bigger HVAC issue in the long run. It can be potentially dangerous for everyone concerned. According to the experts, sweating is a sign of a serious problem not just for your HVAC system but your property as well. As moisture continues to develop on your heating and cooling units, it opens possibilities of damage to the system and the area around your ceiling (if sweating occurs in the ductwork).
Why Does Sweating Occur?In places where the humidity level is high, sweating is a common occurrence. Aside from humidity, there are other contributing factors why sweating occurs. Another significant reason for sweating is high traffic between the space (occupied by your air conditioner) and the outdoor environment which allows both humidity and hot air to get in. When two different air concentrations meet in a single space such as your home, the tendency of your A/C unit is to run longer to maintain a comfortable environment indoor, thus freezing the diffuser. If the warm air gets in contact with the frozen or chilled diffuser while the indoor temperature is below the required temperature, sweating may happen.
Best Ways to Address SweatingTo prevent sweating, it’s important to check some items in your home such as the following.
- Check if your air conditioning unit is running. If yes, set it at a constant operating setting.
- See if the airflow is restricted.
- Make sure to keep the air filters clean.
- Keep the coils on the VAV box free from dust or dirt.
