Hvac Attic Unit Condensation Water Overflow

Occasionally the secondary condensation pan will also clog and not drain.

Hvac attic unit condensation water overflow.

Well mainly it s a way to save space. 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. Water builds up in the ceiling and eventually there will be a drip if the homeowner is lucky. 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.

Air conditioners pull humidity out of the air and funnel the resulting water or condensate into a drain. 3 reasons why the condensate pan overflows. 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.

If the condensate pump is broken or damaged though the water will overflow. A trained technician can usually fix the issue without damaging the line or the pan. Attic hvac systems save space. 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 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. Walk outside your home and look at the condensate drain line. In a functional hvac system the condensate pump automatically turns on when it comes into contact with water. Most updated central air conditioned homes have a new air conditioner split system meaning the ac is broken up into parts.

The water that drains from a central air conditioning unit is condensate that has accumulated on the cooling coils within the unit. When water condenses and drips into your attic or home it can cause a some serious secondary problems. Clogs can be caused by anything from dust build up to mold to mineral impurities in the water itself. This water travels down a small pipe where it ends up in the drip pan.

A wet switch is hard wired to your air conditioning system and placed in the overflow pan. For furnaces in the attic there is a second condensate drain pan. This is in place as an added layer of protection against water damage. If the line gets clogged the water won t drain and it will gradually fill up the pan.

The wet switch will actively shut down the air conditioner. An outdoor unit which houses the fan condenser and compressor and an indoor unit which holds the evaporator and fan. This drain pipe deposits the excess condensed water outside on the ground. The water rises in the drip pan and triggers the pump once it reaches a certain point.

So why put an hvac system up in the attic at all. The amount of condensate the unit produces varies increasing as the outdoor humidity level rises.
