The October heat is here to stay and has us sweltering under. This is the time when we are running our Ac’s to full blast. Working Ac’s to full capacity also may bring forth leakage and cooling issues if the units are not maintained well. These issues if nipped at the bud can prevent it from escalating to major proportions. In this post we share small tips for resolution of leaks in overhead central AC units which could be typically a ductable, cassette or AHU.
The prime reason why an AC drips is because of a hole, crack or overflow in the drain pan.
Like water drips down a cold glass of ice water in the sun, similarly water drips off your air conditioner’s evaporator coils when warm air comes into contact with the cold coils. The pan is a piece of equipment that catches any condensation from the A/C unit; The drain pan sounds like a simple enough part of your air conditioner, but there are a few things that can go wrong with it that can potentially damage your system.
Cracks can sometimes develop in drain pans either naturally or due to something coming into contact with the pan. If a crack develops, water can leak out of the drain pan and onto your air conditioner and concealed ceiling.
Small holes and cracks can be patched with epoxy glue, but it’s usually best to replace a damaged drain pan.
The next culprit—a clogged filter— can be avoided by changing or maintaining the A/C unit’s air filter on a regular basis. A dirty filter will cause ice to form on the unit’s evaporator coils, and when that ice melts, it drips water.
The third and the most common reason could be a stopped-up condensate line—is the most common cause of A/C leaks. If the condensate drain line that’s connected to your drip pan is clogged, water can build up and clog the pan (just like a kitchen sink overflowing due to a clogged drain). If the water builds up too much in the pan, it can begin to overflow and possibly damage your system. The condensate line drains condensation from the drain pan to the outside or directly into a drainpipe.
Another reason to keep the condensate line clear is that most modern A/C units are equipped with a water-overflow cutoff switch, which automatically shuts down the A/C system if it detects a clogged condensate line. The switch helps prevent water damage, which is good, but most consumers don’t know why their air-conditioning system suddenly shuts down and they call a service technician.
