Hereof, what is a secondary drain pan?
The secondary pan is called the auxiliary drain pan. This pan is located beneath the air handler and serves as a warning to the homeowner and professional HVAC technician. If the auxiliary drain pan is overflowing, then it is logical that the primary drain is backed up, clogged, or in need of servicing in some manner.
Similarly, where is the primary drain on AC unit? Find your AC drain line. Most AC drain lines are located outside, near the condenser unit. Push the stiff, thin brush into the end of the drain line. This might clear any clogs located near the end of the drain line.
Accordingly, what is a condensate drain pan?
To safely remove excess water, the condensate drain pan is installed to catch water that drips off the evaporator coils. Then, from the pan a condensate line moves water out of the home, emptying to the sewage system or another external location.
Do all AC units have a drain pan?
Both central air conditioners and room units have drain pans that catch this condensation and allow it to flow outside.
