The wet switch will actively shut down the air conditioner.
Hvac attic unit condensation water overflow.
Air handling units in attics should have a secondary condensation pan in case the primary condensation pan overflows.
For furnaces in the attic there is a second condensate drain pan.
Walk outside your home and look at the condensate drain line.
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.
Well mainly it s a way to save space.
If the line gets clogged the water won t drain and it will gradually fill up the pan.
An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.
The water rises in the drip pan and triggers the pump once it reaches a certain point.
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.
This water travels down a small pipe where it ends up in the drip pan.
Occasionally the secondary condensation pan will also clog and not drain.
In a functional hvac system the condensate pump automatically turns on when it comes into contact with water.
3 reasons why the condensate pan overflows.
When water condenses and drips into your attic or home it can cause a some serious secondary problems.
Any excess condensed water is removed from the air conditioning unit through a small drain pipe that extends from the indoor air handler to outside your home.
Clogs can be caused by anything from dust build up to mold to mineral impurities in the water itself.
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.
So why put an hvac system up in the attic at all.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
A trained technician can usually fix the issue without damaging the line or the pan.
Water builds up in the ceiling and eventually there will be a drip if the homeowner is lucky.
The water that drains from a central air conditioning unit is condensate that has accumulated on the cooling coils within the unit.
This drain pipe deposits the excess condensed water outside on the ground.
If the condensate pump is broken or damaged though the water will overflow.
Air conditioners pull humidity out of the air and funnel the resulting water or condensate into a drain.
Attic hvac systems save space.
Excessive condensation from air conditioning is a sign you have an ac issue.
The amount of condensate the unit produces varies increasing as the outdoor humidity level rises.
If the pan itself becomes tilted or misaligned it will fill up more rapidly and possibly overflow.
If no drip then eventually the entire ceiling will fall.
