I have an LG AC and the lowest temperature setting is 60 degrees

At that temperature the room really doesn't get cool, is it possible to lower the temperature, or turn it off so there's no temperature setting

Lowering the temperature setting doesn't change the temperature of the air coming out of the unit it just lets it run until the room temperature gets colder. Check the temp of the air coming out of the unit. If it isn't as cold as it used to be the charge could be low. First though you should make sure the filters are clean and the coils.You should also check the actual room temp. It's also possible the unit doesn't have enough capacity to keep up with the cooling load of the room.

Is 18 the lowest number on my Delonghi conditioner and the lower the number the coolest?


15 to 20 degrees air temperature difference is what an a.c. will do. 75 degrees return air should be 60 degrees in the supply. If your machine is in that range it is working fine and is cooling all it is ever going to cool. Hope this helps!!

How to cool big home with small air conditioner(s)


A lot of people have only one or two rooms that can take an air conditioner in the window. Often times, the air conditioner is also rated at a cooling power that would make you believe that there is no way that it can to cool the whole house/apartment. You can crank it to the max to try to cool as much as possible, but then this makes one room too cold and the others still stay too hot. You can try blasting the cool air down a hallway with a fan on maximum speed, but that only works so well. And, it's noisy, too. Well, I have two 260 sqr ft rated room air conditioners and I am cooling 2000 sqr feet of house to a comfortable 72 degrees in all rooms and it's been 95 outside all day. How to do it?

The trick is setting up your home to take advantage of laminar air flow. Set your air conditioner to say 68 degrees and start it in the middle of the morning before it feels hot outside. Put the AC deflectors pointing downward and towards the door. Put fans in the doorways pointing out of the rooms that have the AC. Point them level to the floor (not up) and put a fan to one side near the end of long hallways. Set the fans on the lowest power setting (not high). If the hallway branches out into a bigger room, put a fan in the room that is blowing across at a right angle to the entry, pointing the air flow parallel to the wall. This will circulate the cool air around the room. Keep the fans on low and pointed parallel to the floor, not up!

What you have created is a re-circulating air flow system, much like the North Atlantic Current that moderates the temperatures of Europe. You can check this by taking a tissue paper and holding it up to the top of the doorway. The air flow should be pushing the tissue away from the room without the AC and toward the room with the AC. This happens because the warmest air will be toward the ceiling and you want that warm air to make its way across the ceilings and back to the room with the AC, so that it can be cooled again. The cooled air from the AC will sink to the floor and the fans will gently push the air out of the room with the AC. It will stay low and travel along the floor in the opposite direction and into the warmer rooms. If you crank your fans up, you will create turbulent flow and that will not cool your house as efficiently as will laminar flow. Monitor the outside temperature and when it gets cooler outside by a few degrees, turn the AC to fan for about 10 minutes to eek out the last of the cooling. Then open the windows for the night to take advantage of the free cooling that nature provides. That's it! Enjoy the summer!

Why cools the ac only 1 hour full power and never reaches the set-point temperature ?


check that all the doors and windows are closed as ac units do not work well when trying to cool the world
is the ac unit too small for the room size
I suspect that because it is working the problem is outside the ac control
is the inside fan working and blowing out cold air

I have my brand new frigidaire window ac unit set at 60 degrees Fahrenheit, so why does it only cool and keep the room at 65 to 68 degrees Fahrenheit?


if you have it set at 60 F and it is working at 65 to 68 F then that would be about right
as the air is cooled the cold air falls to the floor and out under the door, open window or anywhere else it can escape
the unit has to be at 80% room height so if it is set in a window then when the cold air gets up to the thermostat or ac level in the window then it will stop cooling
So if the ac unit is say 4ft from the floor and the ceiling height is 8 ft then the ac will only cool the bottom 4 ft
cold air does not rise but falls down
if you are using a ceiling fan then the cold air is stirred up and the 65F sounds about right
remember that the setting temp ( what you set it at) is the lowest temp that it will go down to before it stops cooling and if that is not reached it will keep working to attain that temp and if the room is too big, air leaks under door . around the fit in the window , no insulated walls , hot exterior wall,etc then maybe 65 F is the best you will get

My AC unit is 3 years old. its set at 72 but wont go below 78 degrees. im in Las Vegas...Help


Set System Switch to Cool and lower setpoint below room temperature.
Verify thermostat and system wires are securely attached.
Diagonistic: Set System Switch to Cool and lower the setpoint below the room temperature. Within a few seconds the thermostat should make a soft click sound. This sound usually indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation ( . If the thermostat does not click after being reset contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the AC manufacturer or a service person to verify the cooling system is operating correctly.
Or call the techline 18002842925.

Temperature lowering problem.................


Are you referring to 16 degrees and 34 degrees?
If you are, it is not possible to lower the setting to 16 degrees, 32 degreees is freezing, so the evaperator coil would start to freeze up, and as the ice spreads across the coil............... Air can not flow through ice, so the air will stop blowing, till you shut the system down for a couple of hours, to allow the ice to melt.
This is the reason why these units are set with min. temp settings.
I hope this helps.
Sincerely,
Paul Gibson

The AC doesn´t work when outside temp goes 100 degrees and above


Try using a garden hose to wash down the condensor coil (the coil that is exposed to the outside air).
During the cooler times when it seems to be working, check the temperature difference of the air coming out against the temperature of the air coming in (room temperature air). The temperature should be approximately 16 to 22degF difference. If you are not getting at least 16degF air, you most likely need to have your unit serviced to see if professionial cleaning or a recharge is needed. If you are getting the temperature difference but not getting the amount of cooling you need during hot weather, it could be a capacity problem. You can perform a quick test by using the calculator on this site:

I hope you find this information helpful. Good Luck! :-)

AC is just blowing air. The compressor doesn't kick on.


no freon.. pressure test w/ nitrogen. 8000 btus is now junk. Spend the money on new unit otherwise find the leak. It leaked out thats why the compressor will never go on. Once you add freon she'll turn on...same as car.

Dont buy that name brand again. best of luck to you
