6 Reasons of Air Conditioner Freeze Up

Air conditioners are mounted to locations where the sun’s heat primarily dominates as it gives off cold air. It yields countless benefits to the environment and humans’ health, from offering safety and superior quality of life in our own houses. Having said that, as aircon may seem beneficial, it can likewise be linked to several unit issues. Among which is the possibility of freezing up. Below are the reasons why this reality happens.

Different Origins of Aircon Freeze Up

1. Blocked Compressor Coils

Compressor coils are notable as the center of every air conditioning unit as it pumps the cooling agent throughout the system. These are designed to provide enough surface area for the heated icebox to move along as the fan blows cold air across it, carrying away the heat and triggering the refrigerant to condense. When particular debris blows over their air purifiers and coils, it can cause a thick dirt buildup which can function as an insulator, capturing the ventilation inside it. Therefore, creating an excessive amount of freezing, and when mixed with moisture, it generates an icebox effect.

2. Collapsed Air Duct

The duct is the part of the device associated with the constant airflow of cold breeze around the property. Suppose the rest of the system runs smoothly, yet the aircon seems to be slightly off in supplying cool air. The possibilities are – the duct can be clogged thus, blocking the air movement to the coils. When this component collapses, it begins to freeze as there is insufficient warm air to maintain an optimal temperature. As a result of this, the air stops streaming usually and correctly.

3. Congested Air Filter

Intake filters are a significant component of air conditioners involving the house ventilation system and the unit itself, yet they are frequently ignored and neglected. This part functions to catch different debris, particulates, and pollutants, including dust, molds, pet dander, and fungal spores, maintaining the air and compressor coils clean. When this component is blocked, it slows down the airflow, reducing the blower’s efficiency; hence, the coils will start to freeze up. This may need a series of inspections and installation services, so never hesitate to schedule for one from a well-known HVAC service provider.

4. Damaged Blower Motor

Air conditioners are installed with two varieties of motor, the spinning and blower motors. These parts matter substantially in the system as it activates the fan, taking the cooled air to move along the unit, providing a cold vibe around the house. Suppose, by any chance, the capacitor of these motors is damaged. In that case, the fan will instantly stop blowing, ceasing the airflow over the coils. Once this happens, the coils will begin to ice up, creating irregular and rattling sounds.

5. Inadequate Refrigerant

Refrigerant is a chemical compound used for aircon that takes in the heat from the surroundings and deals with the pressure, thus releasing cool air as it goes through the compressors and evaporators. If the recent content of the cooling agent is minimized, warm air can not be converted into gas that heats up and drops the pressure. It would produce enough cold air to condense moisture for ice to develop, thus freezing the equipment and crawling through the copper pipes.

6. Low Voltage Electricity

Commonly, we are occupied and trying to search for the party responsible for unit freezing. Still, we don’t know that electricity could be the root cause. There are different air conditioners offered on the market, and the voltage criteria depend on the unit’s overall size. It is necessary to power up high system components to operate accurately. So, if it is underpowered while the compressor is running, this can trigger an airflow freezing problem.
