Air Conditioning Maintenance - What Does It Mean If Your Air Conditioning is Iced Up in the Summer Months?

Sometimes, your air conditioners will malfunction in the middle of a hot summer day due to an accumulation of ice. Should you observe the formation of this ice formation on your air conditioning unit during summer, it's a good possibility that there's an issue with the unit and therefore it needs to be handled ASAP. While a select few of the causes for an ac unit accumulating ice can be corrected by yourself, any serious discrepancies hindering the unit should in most cases be addressed by a professional air conditioner service contractor. Let's look at some of the most frequently occurring causes for ice materializing on an air conditioner unit.

Lack of Air Flow: In the case that the the temperature of the ac system is very low as a result of insufficient air flow, it can mean a thickening ice coating. Some of the usual suspects that disrupt the air flow in an air conditioner are dusty air filters, weakened blower engines, broken and narrow ducts and the tiny dirt fragments on the evaporator coil itself.

Refrigerant Deficiency: Pressure deficiencies in the evaporator coil are common if there is a low level of refrigerant in the ac unit. In many cases, this causes moisture to freeze and accumulate on the evaporator coil.

Low Outside Temperature: An air conditioning unit may not work properly if the evening temperature is too low, another thing that can cause the unit to freeze.

How do you repair a frozen air conditioning system?

The air conditioner freeze ups should be dealt with immediately, or else it can cause serious damage to the system. Initially, you can check and see whether the internal fan and the compressor are running at the same time. If you observe a decrease in cooling ability or buildup of ice, first the air conditioner needs to be turned off and it ought to be allowed to defrost all the way. After this, the procedure is to gauge the flow of air and make an attempt to observe any noticeable stoppage to the flow of air like musty air filters or small pieces of debris. If the air compressor is running and the evaporator fan is not working, this might be the most likely cause of building ice in your ac unit.

A lot of problems that effect the thermostat may also cause an accumulation of ice on the ac unit. If the fan relay is not running, the circuit might be open in between the thermostat and fan relay. If this is something that you encounter, broken wires or lost connections ought to be monitored by either you, a relative, or a licensed air conditioner service technician.

Lastly, the blowers might cause the evaporator coil to build up ice. When the motor is reversible, it should be switched around or a fully functional motor should be installed. A problematic blower may also be the cause of ice accumulation in the ac unit. Should it happen that the blower motor is not big enough or undersized, or its bearings are not working properly, it could result in too much heat and may stop working every now and then. An optimal solution is to contract a trained air conditioner technician to replace a working blower motor.
