If the line gets clogged the water won t drain and it will gradually fill up the pan.
Hvac attic unit condensation water overflow.
Air conditioners pull humidity out of the air and funnel the resulting water or condensate into a drain.
For furnaces in the attic there is a second condensate drain pan.
Air handling units in attics should have a secondary condensation pan in case the primary condensation pan overflows.
Excessive condensation from air conditioning is a sign you have an ac issue.
So why put an hvac system up in the attic at all.
3 reasons why the condensate pan overflows.
This is in place as an added layer of protection against water damage.
Occasionally the secondary condensation pan will also clog and not drain.
A wet switch is hard wired to your air conditioning system and placed in the overflow pan.
Well mainly it s a way to save space.
In a functional hvac system the condensate pump automatically turns on when it comes into contact with water.
Attic hvac systems save space.
Walk outside your home and look at the condensate drain line.

When the pan becomes filled with water it will shut down your air conditioner so no more condensation can be formed and overflow the pan.
The water rises in the drip pan and triggers the pump once it reaches a certain point.
The wet switch will actively shut down the air conditioner.
First water dripping off of your ducts and onto your insulation can cause the insulation to compress which decreases it s r value or ability to insulate.
If the pan itself becomes tilted or misaligned it will fill up more rapidly and possibly overflow.
This drain pipe deposits the excess condensed water outside on the ground.
Water builds up in the ceiling and eventually there will be a drip if the homeowner is lucky.
Because entire central air system is lying on its side in the event of condensate drain pan failure water does not drip in one general location.
This water travels down a small pipe where it ends up in the drip pan.
The water that drains from a central air conditioning unit is condensate that has accumulated on the cooling coils within the unit.
The amount of condensate the unit produces varies increasing as the outdoor humidity level rises.
When water condenses and drips into your attic or home it can cause a some serious secondary problems.
A trained technician can usually fix the issue without damaging the line or the pan.
If no drip then eventually the entire ceiling will fall.
This is a list of the top 10 reasons that your ac unit may be leaking water inside or outside of your residential or commercial property in 2018 2019.
