If you close off the vents to unused rooms you need to watch out that the evaporator does not freeze up. An indication of this would be the black insulated suction line starting to ice up.
Other than that make sure you open them back up when heating roles around.

What is the setting for the push-pull lever on the right side of my in-window air conditioner? thanks


If you want to pull fresh air into the room and not use the cooling part of the unit. pull the lever out. If you don't want to introduce fresh air into the room during the cooling cycle, push the lever in.

Thanks for choosing FixYa.

Hi Water is spitting furiously out of the front of our 3 month old air conditioner... what should I do?


Wow i thought i just answered this one. Check the filter and be certain its clean then If it has a hose for a drain make certian that it is not kinked . if not just make certian that he unit is tiled to the ouside about 1 inch or so. also this is a small unit so close the doors to all unused rooms and check to be certain that the fresh air vent is closed . some times called outside air as well.

18,000 BTU Window Air Conditioner keeps 'freezing' up.


Lgvjr50. A couple things here might solve this problem. 1. check the filter and service it by washing it out or replacing it. 2 be certain that the fresh air vent is closed .# When you clean the filter shut it down and get a hair dryer and defrost it really well before you turn it back on again..4 .close all unused rooms if at all possible. I hope this works for you and solves this problem let me know will ya? Jon

I have a window air conditioner and it has been doing good for 2 months. Now lately drops of water are flying out of the air vents, what gives?


This tells me you have possibly 2 problems..
1. you need the unit to tilt to the back (outside) to prevent the condensate from coming inside.
2. the unit might be iced up. meaning it is not cycling off -often enough. this is a window unit so you might be trying to cool to big a space with it on real humid days. i would advice you close off unused rooms as well.. But my money is on 1.

Should air cooling unit vent be in or out


If this is a forced air system and you are talking about the wall vent. It is very ossible you will need to
make sure your blower motor on the indoor unit is
on high speed. Sometimes in the duct work they put
a manual damper, follow ductwork back from room until you find one or not and make sure it is open.

Describe your Kenmore Air Conditioner Proble. My


the vent is a fresh air intake, when it is pulled open you are mixing outdoor air in the unit. when it is hot and humid outside you will make the unit struggle to cool. Leave the vent closed.

F1, F2, and F3 are the strength of the fan blowing the air conditioner. F1 circulates the least amount of air, F3 the most. I generally find that if the air conditioner isn't getting the job done on F1, F2 will do it. I typically only use F3 if I just want to circulate air fast in my place for awhile. As far as what is "better" with closed vent or open, that depends on what you want to do. If you are using air conditioning on a hot day, then vent closed is better because it will cool only air circulating in your place. Vent open will allow fresh air in from outside, and if it's a really hot day, the air conditioner might have a harder time cooling off the fresh air than the circulating air inside your place (as it's continually being cooled repeatedly by your air conditioner).

F1 - F3 are the fan speeds when the air conditioner is in fan only mode.

The vent can be opened or closed based on your preference. When the air conditioner is in a/c or dehumidifier mode having the vent closed will cause the a/c unit to recirculate the room air and cool / dehumidify quicker. When you open the vent the a/c unit takes air from outside and cools / dehumidifies it. It is obviously not as efficient this way but it does bring in fresh air.
