Understanding The A/C Drain Pan
What is an A/C drain pan?
An A/C drain pan is an essential component of any air conditioning system. It is a shallow, usually metal or plastic, tray that is strategically placed beneath the evaporator coil of your A/C unit. The primary purpose of the drain pan is to collect and drain the condensation that forms on the evaporator coil during the cooling process.
Location and function of the A/C drain pan
The A/C drain pan is typically located underneath the indoor unit of your air conditioning system. It sits below the evaporator coil to catch the condensate that drips down from the coil. Once the condensate is collected in the drain pan, it is then drained out of the system through a PVC pipe or hose connected to the pan. The drain pan essentially acts as a safety net, preventing water from leaking and causing damage to your home or the A/C system itself.
Different types of A/C drain pans: primary and secondary
There are two main types of A/C drain pans: primary and secondary. The primary drain pan is the main pan directly underneath the evaporator coil and is designed to collect the majority of the condensate. It is usually larger in size and has a drain outlet for the condensate to exit the system. The secondary drain pan, also known as the overflow or emergency pan, is a backup pan that is installed beneath the primary drain pan. It serves as a safeguard in case the primary pan becomes blocked or overflows. The secondary pan typically has its own drain line that will redirect the water to a conspicuous location, like outside your home, to alert you of a potential issue.
