The in-depth guide about frozen Air Conditioner will help you to troubleshoot this issue. Although to figure out the exact factor which can contribute to freezing up the air conditioner is exhausting. Home-owners often experience dismay, realizing insufficient freezing of air conditioner at some point or another. If the problem of Frozen Air Conditioner is not timely addressed, it not just adversely affects the cooling but also damages the important components of an AC unit. Therefore, in the first place, one should fix out the problem before it gets worse. Here you go with factors that can ice up an air conditioner.


Thermostat and drainage problems

The prime causes, which often lead towards freezing up the air conditioner are either the faulty thermostat or refrigerant leak. The air conditioner condenses water vapours into liquid. If the coil somehow freezes, the ice blocks the drain hole and does not let your place to warm. On the other hand, a leak in the refrigerant line reduces the pressure, that causes the refrigerant to expand, making evaporator coil colder than usual.

Faulty blower fan

The blower is responsible to pull in all the warm air and then distributing fresh air evenly. The malfunctioning of a blower fan can result in the accumulation of ice on the evaporator coil. If the fan is dirty, damped or blocked, homeowners can easily clean it.

Low Temperature

The low outside temperature can be a reason of icing up of the air conditioner. Ambient heat transfer is essential for smooth functioning of the equipment. For instance, if the outside temperature is somewhere between 15-16°C, the system can’t remain efficacious and the ice will start building up.

Evaporator coil needs cleaning

It is obvious for the debris and dirt to build up in the central heating and cooling system. Over time, dirt will start accumulating on the evaporator coil, which ultimately makes harder for the refrigerant to absorb heat. The irregularity in the heat absorption patterns result in condensate to freeze.
Mostly, homeowners lack the expertise to clean the duct or do not bother to unclog the ducts at all.

Improper Air Flow

The air conditioner cools the entire place effectively when warm air is pulled into the ductwork, and the evaporator coils expel the heat outside. The refrigerant absorbs the heat; that prevents the moisture from freezing. The improper heat flow is the foremost cause of many complications therefore, experts recommend – problems associated with improper air flow should be addressed instantly. The poor airflow can also be the reason for turning condensate to the ice. The common issues of poor airflow, that most of the homeowners do not investigate are:
·         Leaky or clogged air ducts
·         Blocked dampers or gates
·         Dirty filters
·         Debris in the supply registers

Wrapping up:


A frozen air conditioner sounds strange but it happens with the most of air conditioner either by a reduced pressure due to a refrigerant leak or warm air not finding the way to go to evaporator coil or low ambient temperature.
