Ice on the coil fins of my Window AC unit......

I noticed that there is a think blanket of ice forming in the coil fins of my Window airconditioning unit. It seems the ice is "blocking" the air coming from the fans of the AC unit so, there is less cold air coming from the unit because of the ice. What seems to be the problem??

Set your unit to fan mode only, to thaw the ice, after the ice melts, look at your evaporator coil, see if its dirty, if its dirty, then you might just need a good cleaning. if the coil is clean, look at your thermostat setting. it should not be all the way cold. the compressor would run continously and it would freeze the coil. third, the refrigerant system could be partially clogged up or it lacks refrigerant. these problems initiate freezing of the coil.

Ac not cold floor always wet passenger side.Every thing seems to work under hood all hoses are cold. pump comes on. fuses are good i made sure drain hose NOT plugged. blender seems to work the other opens...

You will find that the fins of the evaporator ( ac unit in car) are blocked up from gunk the floats around inside the cabin.. You may be able to clean it with an ac cleaner or compressed air. What is happening is that the gunk is forming ice which tells the TX valve that the temperature has been reached and so the ac compressor shuts off . The ice melts and the circle is repeated.. You may be tinkling as the ice breaks free of the fins and falls inside the ac box.

The indoor unit of my 1.5 T , 2 yr old split ac is making noise like cracking of ice or plastic whenever the compressor is tripped or restarted. I've noticed water leakage (splash) from indoor un

the ni oise you hear is the ice breaking up and the splashing is excessive water in the blocked drain that cannot run outside

I have ice fooaming up in front of my air conditioner. What could that be. Never happen before

ice forming in front (where evaporative coil is located) of your AC is caused by one of two things.
(1) low refrigerant charge
(2) low air flow over the evaporative coil
I do not think it's likely that 'low refrigerant' is your problem because generally speaking - you won't lose the refrigerant out of a window unit barring an accidental puncture, or maybe from dropping the unit or something like that.
Therefore I would suspect that you have - reduced air flow over the coil - and the most likely reason is the coil being dirty/clogged.
I would take the unit out of the window and wash it real good ( a water hose with a pressure nozzle works really good).
Be sure to let the unit 'dry out' really well before turning back on.
Note: be sure to not turn the unit upside down/or on it's side for any extended length of time.
Also - your fan motor running slower than normal could cause this - but this is a rare occurrence.

Cooling fins surrounding coils are freezing and

mcdevito75 here, Possibly, the filter needs cleaning / replacement, unit set to too cold. Shut A/C off, let the ice melt on it"s own DO NOT REMOVE ICE YOURSELF, those coils have the fren gas in them, when the ice is all melted restart unit, set temp. not so cold, around 60--65 degrees, and have exhaust to out. This shpoul;d help, you can always check with your local A/C repair shop, they come to the house.

Ice is forming on coil fins

Either your coil is dirty or filter is dirty. Worst case your low on freon which would make a coil freeze.But freon doesn't evaporate if your low there must be a slow leak.

Ice formation on the fins- after about 20 minutes of putting it on, a comlete ice (snow) sheet forms on the fins-blocking airflow into the ac.

three possible prolems here 1 check the evaporator coil and filter to see if they are dirty and need to be cleaned dirt gets into the coil by by-passing the filter or the filter is no longer able to contain the dirt. 2 if there is a opening in your furnace that allows air to the furnance without going through the return air vent this could be a cause 3 low on freon in which a tech will be needed to check. Also check the outside unit and see if the coils have a lot of debris on them if so you can use a garden hose to clean them but make sure to have the power off and just spray the coils nothing else. Good luck

1.5T Voltas Vetris window AC. Ice formation

I think the more likely problem is that the unit is slightly short of gas\ refrigerant, which is a common cause of icing up evaporator coils and this sound you describe. First check that the air filter is clean. Another cause could be the defrost sensor is faulty, but I would think not. Some ice isn't actually a bad thing, but quite common as long as it doesn't form over too much of the coil, or get too thick.

Coil and fins start ice up

The fins are dirty. They need to be washed every year or two with an acid based cleaner. They MUST be rinsed completely.

My cooper line outside on my air conditioner keeps freezing over causing my ac to blow warm air instead of cold air

The evaporator coil that is low pressure and low temperature needs an adequate supply of heat to absorb from air passing over the fins or a thin dusting of frost will begin to form further insulating the coil from the passing air and causing more ice to form. First you have to get rid of all the ice by allowing the coil to thaw you can use a heat gun or hairdryer or lamp to speed the thawing but the fins and copper tubing are thin and easily damaged so don't use tools on the coil to remove ice. After thawed the coil needs to be cleaned with an indoor evaporator cleaner ( I also use a small shopvac and nylon brush) Then be sure that the filter is clean and the blower is functioning properly then if the suction line is still frosting you will have to verify that the size of the outdoor section is not over sized in relation to the evaporator coil and that the system is charged to meet the compressors manufactures specifications.
