Dirty filter or evaporator coil, blower speed set too low, obstruction in supply or return duct, system is oversized or mismatched and there is no way you can tell if the unit is low on refrigerant or not until you solve the icing problem.
Typically in my experience as a handy employee and homeowner for the last 40+ years, when a refrigeration unit ices up it is because the thing is working too hard and/or the coils and radiator is full of dust/debris.
*Assure that the delivery lines are well insulated so the cold freon is still cold when it gets to the exchanger in the ducting part of your heating system. *Insulate the house and preserve your cool air as much as possible, keeping in mind that it is dollar bills blowing out the doors, windows and cracks.
*The unit must be 3+ feet clear of weeds, junk, sheds, tools, toys, etc. to allow it to breath, and keep it spiffy clean and try to cover it in winter.
*There usually is a fuse box outside near the unit that should be flipped at the end of season to eliminate it from accidentally being turned on in cold weather, which is supposedly very bad. Just do the cover when you do the fuse flip.
*Finally if this continues, the thing need a real pro to check it out. If it needs a recharge, it has a leak. This can be bad and if it is older, it may be wiser to get a new or newer used model to gain reliability and efficiency.
Defrost it, remove any food, the switch off the freezer, leave the door open and alow all the frost/ice to melt, then clean the freezer and switch on again. If the freezer regularly frosts up then you may have a faulty door seal.
The unit is most likely low on freon and needs to be recharged, or there is not enough airflow through the unit.

Or you are asking the unit to do more than it was designed to do, next time try lowering the temperature slowly. If your home has been closed up for a long period then there is probably an excess of humidity and the unit is trying to dehydrate the air beyond what it is capable of doing. Try incremental cooling... lower the room by two degrees at a time and allow the unit to cycle off and on. The continual use of the unit is what is making the ice build up.
If by aluminum radiator core you are talking about the indoor coil, you may be low on refrigerant, have a dirty filter, or the indoor blower is not working properly.

You're not getting enough air across the evaporation coil. You'll need to either install a larger fan or replace your filter.
air conditioner condenser coil icing up
When you are running your air conditioner and it stops then the air conditioner is froze up. You have to cut it off for a while, and let it warm up. You have to turn the thermometer between 70-75 to keep it from freezing up.
The air conditioner provides cold air inside your home or enclosed space by actually removing heat and humidity from the indoor air. You can check acservice.sg for aircon installation, aircon gas refilling or top-up solutions, and aircon troubleshooting.
Could be several things...It could be low on refridgerant or the coils could be dirty. Check the coils first as this is something you can do your self.
Duct work adds allergens to home because they fill up with dust and dirt. When the air conditioner comes on, this dirt fills the air. A filter is needed to help limit this. Ductless air conditioners are cleaner.
This has much to do with how the air conditioner and the heater is vented. If the air conditioner draws its air from outside it could be picking up air / smell of smoke from the other family and then redistributing it into your home. A heater on the other had usually has a heater input vent within the house it is heating (it draws the interior air in and then heats it blowing it back out) as the air within the home will be significantly warmer than the exterior air.

NO If the unit is on its side or upside down, the oil can run out of the compressor and it will seize up. They do make a vertical air conditioner to fit into the taller windows which open side to side.
Check out home improvement places and depots like Lowes, Home Depot, Builders Square, Pilot Lumber, and Do It centers for air conditioner costs. Also look for "Mom and Pop" places and other home improvement to get the cost of an air conditioner. Get estimates and trust the professionals to do their job right. If they weren't good, they wouldn't still be in business!
Central of course because it is larger.
You can find a cheap air conditioner at a place like Lowe's or Home Depot. Any where that sells air conditioners is helpful, I would ask someone that works there for more information.
Inspect the instruction manual in case there is an easy fix, otherwise call up the manufacturer in order to hire a handyman to come and solve the problem or find someone locally to come and fix the air conditioner
Because a fan only stirs up the hot air while an air conditioner removes humidity as well as cools the air.
