Problems That Can Develop With the Condensation Drainage System Parts in Your AC
Your air conditioner pulls humidity from the air every time it kicks on. It does this by creating condensation as the air flows through the evaporator coils in the air handler. The condensation water collects in a pan and drains away safely under normal conditions.
You may even forget all about the condensation pan and drain since you rarely have to service it if you have annual cleaning and maintenance from an air conditioning service.
