Depends on the ambient temp outside. If it's lower than 65 it will freez up because the is no load on the condensor. Try putting a bourd across the condensor coil and it will creat a load on the compressor if it still freezes up than it's a low charge!!

How to check air flow on a window unit ac

Clean the filter. If the coil is frozen it will not be producing much air. Turn it off for a while until thawed. Then restart machine. If the blower is working and the filter and coil are clean then you are low on refrigerant

Ac unit freezing up

The most common problems that causes the lines to freeze up are the charge of refrigerant in the system or a restriction in air flow. The charge will have to be checked by a technician with the proper tools, the air flow can be checked yourself though. You will want to check your return air filter to make sure it is clean, then when the unit is NOT froze up, turn the fan on to the furnace and see how much air comes through the vents. If you do not have the same air flow or no air at all, your indoor coil might need to be cleaned or your blower motor isn't coming on, which will usually be a bad capacitor or the motor itself. Hope this steers you in the right direction and good luck!

The unit freezes up

When a AC freezes up the most likely reason is that the evaporator coil (the one the cold air comes from) is 'dirty,' and/or the filter (that goes in front of the coil) is also 'dirty.'

Be sure to defrost the unit (if it isn't already).

If it presently has ice on it - just turn the unit to FAN ONLY and allow it to completely defrost (all ice gone).

Then: Be sure the filter is 'clean' and air can flow through it.

Be sure the coil is also clean.
Note: if the coil is dirty you can usually clean it fairly easy with a brush. Often (especially if the unit is freezing up) you can actually 'peel' a layer of 'wet matted stuff' from the coil by hand.

Another reason (less likely one) for the unit freezing up - is that the fan motor is going off (when it shouldn't) and the "lack of any air" over the coil is causing the unit to freeze up. You didn't say anything about the fan motor not running so it's not likely this is your problem - but be aware - that fan motors can get hot and will go off on internal overload - UNTIL - it cools down and then will come back on - so - if you're not watching - it's possible the motor could be "heating up and going off (for 30-90 minutes) and coming back on" without you realizing it, which would cause the unit to freeze up. Like I said - this is not likely though. If, however, it is doing something like this - the 'sure-cure' is to replace the motor. The cost to replace a blower motor will be somewhere in the neighborhood of $200 which should cause one to think about buying a new unit.

Another reason - also 'less likely,' is that the AC is 'low on refrigerant.'

If - after checking the filter/coil - you find that they are both clean and not causing the problem - and you've watched the fan motor and it's not going 'off and on,' then, you must consider that the unit is 'low on refrigerant,' which will require a Service Tech - who has the expertise and tools to repair the leak and re-charge it. If this is the problem you're probably looking at a repair bill of $75 -$125 - which when considering the price of 'new air conditioners' might cause you to think about buying a new one.

Hope this helps.

Kelvinator aircon is dripping water from air vent in house

Sounds as if unit is freezing over----typically a response to lack of proper ventilation-----check all filters and access panels to unit and clear or clean as needed-----if unit has a drip pan make sure unit has been positioned properly so as to catch excess......properly ventilating unit should resolve issue though

Wall ac unit keeps freezing up inside.

Do not run it on maximum cool and fan on low. Freezes up all the time this way.

My Coleman Evcon AC unit ices up everytime I turn the unit on

If the AC unit doesn't have sufficient air flow to carry away the cold air then condensation and the extra cold air will freeze at the unit. good air flow is the solution. Change the filters, clean the unit by removing the covers and looking for pet hair/leaves/dirt inside the coils of the unit. and make sure the ducting is connected and not clogged.

Hi, Sounds like its low on refrigerant. Could also be restricted air flow inside. Turn the AC off and the inside fan on for about 3-4 hours to thaw out the evaporator. Replace the inside air filter. If you can see the side of the evaporator that the air goes into, check to see if it has a blanket of fuzz on it. If so, It can be cleaned with a credit card while its wet by scraping along with the fins. Turn the AC back on and let it run for about 20 minutes. The large line outside should sweat all the way to the compressor but the compressor should stay mostly dry. There may not be anything wrong with you unit. When it is cooler at night they will sometimes freeze if the thermostat is turned down too low during the night and the air restriction will not let it thaw during the day. Hope this helps. kstfas
