First is to make sure that your air filter is clean so you can move adequate air. If it is already clean, then you have a freon leak. The unit could be repaired by an a/c tech but repairs are almost always more costly than purchasing a new unit (I assume this is a window unit)

My portable windchaser airconditioner pacr9 sounds like theres some water in the top area and is blowing out some water from the front vent ? any reason why ?

This usually happens when the unit is dirty. The filter provided is pretty worthless and dirt and dust build up inside the unit badly. This causes the unit to operate inefficiently. Condensate builds up on the evaporator and freezes. When it defrosts water drains through the unit to the bottom, whats left is a muddy sludge and a clogged evaporator. The condinsate will then overflow into the fan area. Normally the condensate will be exhausted through the warm air vent in the back of the unit.

To fix this, you need to unplug the unit, then remove the entire back cover. Not just the small cover on the upper portion. Once removed you can then have access to the entire evaporater and condenser. Clean these thoroughly with a vacuum and toothbrush if necessary, Let the unit defrost if the evap was clogged with ice. Drain the unit thoroughly with the tube at the bottom of unit. I lay a thick towel on the floor and let it drain into the towel. Clean the fresh air intake area on the upper rear thoroughly, I used windex, then flushed with water, which ten drained to the bottom of the unit, and out onto my towel. Reassemble and run in fan mode for an hour, allowing the condensate that overflowed into the fan area to evaporate. You should be all set.

This maintenance procedure should be performed yearly or as necessary on these units.

We have a Carrier 25HBA unit and we've noticed a frost build up on the outside compressor, my husband turned the unit off and cleaned everything outside and up in the attic. It worked. No frost...

Frost or ice on the bigger outside copper line is a indicatin of possible low freon.Hopfully that is all it is.

It is also a possibility the compressor is getting ready to break,bad valves.

You will need a tech to come out and charge the system with freon.

Check your filter is clean and new first.

Airconditioner has weak cooling power.

if all the coils on the out side and inside units are clean and the fan motors are running fine it sounds like it could be low on freon
