A faster way is to on the air conditioner but using Fan mode. That means, only the fan is operating but the compressor is off. This will reduce the melting time of the ice but you will need to be around to monitor it as water may overflow and cause damage to your furniture or electrical items. A low refrigerant problem can only be solved by a qualified HVAC technician as additional refrigerant will have to be added to the system.
Another possible cause is when you are operating your air conditioner when the outdoor temperature outside the house is low. When this happens, try to run the air conditioner using fan mode or simply use the outside air to ventilate your room.
For such equipment to operate, one way is for manufacturer to install a fan speed controller to regulate the speed of the condenser. What if your unit is operating in heat mode and frost builds up at the outdoor?
See more explanation here. Here are the some of the troubleshooting heat pumps tips and information if your unit is not working properly. Here is some basic split airconditioner control troubleshooting for a simple ductless split air conditioner or a simple electronics window air conditioner. Air conditioner refrigerant has become a hot topic due to its effect on the ozone layer of our earth.
Visiting HVAC events and trade shows are one of the best way to equip yourself with the latest happenings in the air conditioning and refrigeration field. See the listing of events for year Here is the HVAC Directory of the manufacturers, professional bodies and industrial associations related to heating, ventilation, air conditioning and refrigeration. Without drainage, condensed water will stay inside an AC unit, where it will eventually freeze. During the cooling process, water vapor condenses into liquid, which then drains into a drain pan or outside.
Frozen coils can block the drain hole further, which is how a minor freeze becomes a major one. In other words, the more ice appears on the coils, the worse the drainage gets, which causes even more ice, and so on. Improper refrigerant fluid levels can also cause an HVAC unit to freeze up. When the refrigerant is low, the coils will be too cold, causing them to freeze.
You can hire air conditioning service and repair to check your refrigerant levels and replace them, if necessary. Be aware that if your refrigerant levels cause the unit to freeze up, your coils can become damaged, which can then damage the compressor. Today we are taking things a step further and discussing why does an air conditioner freeze? One of the most common reasons your air conditioner to freezes up is due to a clogged filter.
An ac unit needs adequate airflow to keep critical parts warm. Other reasons include low refrigerant, fan operation, or unexpected rain. The cooling from your air conditioner is supposed to go into the air that passes over the coil. If there is not enough air, the coil becomes very cold and freezing temperatures occur.
The ice blocks the airflow even more, and ice forms rapidly on the coil. Low airflow occurs because of dirt clogging the blower or coil, grilles that are blocked or closed or the mechanical failure of a blower component.

Most of us have experienced an air conditioner that will not cool because it is low on refrigerant. It is difficult to understand how an air conditioner can freeze up for that same reason.
It has to do with the science of pressure and temperature. Perhaps you have experienced it takes longer to boil an egg in the mountains than it does here in Jupiter, Florida. When activated, the refrigerant actually needs warm air to blow across them. This cools your air and keeps the coils warm enough that they do not freeze over.
On a straight cool system, your indoor coil removes heat from the inside and transfers it using the refrigerant to the outdoor coil which pushes the heat to the outside. Because the system is pulling heat from your indoor air and transferring the extra heat outside. It does this by manipulating pressure via the refrigerant circuit. But if something stops the warm air from blowing over the coils or if the pressure is wrong inside the coils, then the coils can become too cold and can quickly freeze up.
The reasons why the inside of your AC can become a frozen-up icebox relate to either airflow, pressure, or both. The more moisture there is in the air, the more ice builds up. It covers the inside of the AC like an old chest freezer and crawls up the copper pipes. We get the majority of our frozen AC calls during Monsoon season when homeowners begin to see ice crawling up the copper piping all the way to the outdoor compressor.
The single most common reason why your AC can freeze up is lack of airflow. This can be caused by a number of different malfunctions ranging from the blower motor to the air intake. If anything in the airflow system stops warm air from flowing over the coils while the compressor continues running, your AC will start to freeze up and this only gets worse with time.
