Home central ac units why is my over flow leaking in my home?

Answer 1

this could be caused by more than one thing. First, in your AC unit there is a condenser that will take the moisture out the air, this collects and drips into a tray & from the tray out a drain pipe. if that drain pipe gets plugged the tray will fill up and over flow its' sides, which means it could seek the most direct route to the ground ( downward) and maybe follow your ductwork into your house. A quick fix for that is to take your wet/dry vac and and seal your vac intake hose with your hand around the AC drain pipe and let it suck, if it is plugged your vac will struggle, now turn it off and switch the vac hose to the exit on your vac so that it blows and seal on drain pipe and blow out drain pipe. Switch back and let it suck again. If that was the problem, then you are done. However, there are a few other possibilities. Low freon, dirty heat/exchangers dirty filters (the filters are cleanable or replacable) if the freon is low or the air flow is blocked or both then the unit can freeze in areas that do not have a drain tray and even though it is freezing it will be melting some as well and this melt run down into your unit and into your house. Things you can do are clean and or change filters, then look at your unit for water anywhere around the base, probably on the opposite side from the drain pipe. you will need to open up a side panel to the unit and see where it is iceing up. If you run this unit all the time and it is very humid where you live and if the unit is old or has not been serviced in years, then lack of air flow and low freon could be the problem. I hope this helps
