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.
Hvac attic unit condensation water overflow.
This is in place as an added layer of protection against water damage.
Clogs can be caused by anything from dust build up to mold to mineral impurities in the water itself.
Well mainly it s a way to save space.
For furnaces in the attic there is a second condensate drain pan.
A wet switch is hard wired to your air conditioning system and placed in the overflow pan.
Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.
3 reasons why the condensate pan overflows.
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.
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.
Attic hvac systems save space.
This drain pipe deposits the excess condensed water outside on the ground.
Air handling units in attics should have a secondary condensation pan in case the primary condensation pan overflows.
Occasionally the secondary condensation pan will also clog and not drain.
Air conditioners pull humidity out of the air and funnel the resulting water or condensate into a drain.
The water rises in the drip pan and triggers the pump once it reaches a certain point.
An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan.
If the line gets clogged the water won t drain and it will gradually fill up the pan.
In a functional hvac system the condensate pump automatically turns on when it comes into contact with water.
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.
If the pan itself becomes tilted or misaligned it will fill up more rapidly and possibly overflow.
So why put an hvac system up in the attic at all.
This water travels down a small pipe where it ends up in the drip pan.
If no drip then eventually the entire ceiling will fall.
Excessive condensation from air conditioning is a sign you have an ac issue.
The wet switch will actively shut down the air conditioner.
Walk outside your home and look at the condensate drain line.
If the condensate pump is broken or damaged though the water will overflow.
Water builds up in the ceiling and eventually there will be a drip if the homeowner is lucky.
When water condenses and drips into your attic or home it can cause a some serious secondary problems.
The water that drains from a central air conditioning unit is condensate that has accumulated on the cooling coils within the unit.
