[QUOTE="Marg's Man, post: 307602, member: 4085"] Air Conditioning 101 - apologies now if I say something that you already know. This should give you some ideas that may avoid a service call. First What kind of AC have you got? A Refrigeration type or the type that blows air through a filter cooled by water from a tank you keep filled, we call those Coolgardies in Australia. In TN I hope you're using the Refrigeration type that works by cooling the air directly as it blown through chilled coils. Excess water condenses out of the cooled air and has to be drained away, usually via a drain that leads outside. Often this drain is inconveniently located so there is often some sort of tube or pipe to get the water where you want it to be. If you are getting leaks inside the building then something is wrong with this drain system, so this what needs checking. Some ideas have been mentioned already, cracked collecting trays, insufficient slope. You need about a 1 in 40 slope for water to drain reliably, PM me for details on how to work out slope if cannot. If enough people ask I'll post it. The next most common cause is a blocked drain. Start by locating the point in the tray where the water drains away. This may be a simple hole or have a short (less than an inch long) pipe moulded into the tray. This hole can get clogged with a slimy mixture of algae and dirt. It can be poked out with a finger or a some sort of wooden stick (skewers are perfect) if you are squeamish. Be careful not damage the tray if it is not already damaged. If the tray exit is clear and there is a long tube or pipe then this where the blockage will probably be. Use whatever it takes to make sure this tube is clear. Another possible cause is due to the coils (the bit that looks a like car radiator) icing up. This is located where the tray cannot catch the water as the ice melts so it runs the wrong way. The most common cause for icing up is loss of the gas in the system, THIS needs a call to the service technician. If you have a Coolgardie type then there is a simple water leak in the tank or drip tray which you just have to find. I don't think you'll have one of these because they are hopeless in areas that are not desert dry climates. They make humid air even more humid without cooling as well as normal and they don't cool much normally! It's just matter of find and fix the leak - not always easy if at all possible.
