I live in an outdated high-rise apartment building. There are several things that could actually be substituted, but since the rent is so reasonable, I try not to complain. However, I did call the property owner about the drips coming from the window a/c one floor above me. At first I thought that it was starting to rain outside until I realized that the sun was shining. After I took a closer look, I could see a steady leak coming from a/c above me. The property owner told me that some condensation is normal due to the dehumidifying process. But when I described the amount of water that was dripping, he decided to call an Heating, Ventilation, and A/C professional. The next morning, I was surprised to get a call from the heating and cooling specialist, since it wasn’t our a/c that was having the problem. But he explained that he couldn’t reach the tenant that lived above me. So I ended up having a surprise conversation with him about a/c’s. I never knew how various things there were that could cause water troubles, however I soon got quite an education. For one thing, the condenser pump might be broken. Or, if the unit was not installed, the leaking could be caused from an a/c that wasn’t level. If the vents are closed or clogged, the resulting pressure might be the cause of the a/c leak. Finally, if the drain hole in the unit is clogged from debris, the built-up water could absolutely lead to leaks. By the time both of us ended our conversation, he finally asked me if I could ask our neighbor to give him a call.
