Good evening folks!
My central AC is a Lennox system with 3 zones, installed in 2010, inside unit is the basement, outside unit is at the ground level. Inside - there is a small tank (12'' x 4'') on the floor to collect water and has a motor to send it outside (see pic attached). The water from condensation pan is sent to the tank via a PVC pipe that is about 4 feet long, 1 inch diameter, with only 2 bends. More than 3 feet of the pipe is vertical. when i filled the tank to 80%, the motor started automatically and emptied the tank in 30 seconds. that means the water on the floor is not coming from the tank. Last week i changed the capacitor in the outside unit and the filter in the inside unit.
I had kept the AC off for 2 days. today I ran it for about 2 hours, it did not cool the house much, only 2-3 degrees (from 84 to 81), The coil system was not icy. the thick metal pipe was cold (but not super cold) and the thin pipe was warm. The water level in tank did rise. So i am not sure if the PVC pipe is clogged. I found that the water-collecting-pan has about half to 1 inch of water in it.
- Is that normal or the pan is supposed to have no water at all?
- could it be that the pipe is almost (but not fully) clogged hence the tank gets some water, but the pan also gets full?
- can the water leaking problem prevent the AC from giving cold air? i thought the water is created only when the cooling part is working fine?
- should i open the outside unit, remove the fan and clean it from inside?
- what are the chances the unit low on refrigerant ?
Thanks in advance
