Air conditioners are installed in locations where the sun’s heat predominantly prevails and emits cold air. It generates numerous advantages to the environment and humans’ health, from providing safety and superior quality of life in our own houses. However, as aircon might seem beneficial, it can likewise be linked to various system issues. Among which is the possibility of freezing up. Below are the reasons why this reality happens.
Causes of Air Conditioner Freeze Up
1. Blocked Compressor Coils
Compressor coils are notable as the center of every air conditioning unit as it pumps refrigerant throughout the system. These are designed to supply adequate surface area for the heated icebox to move along as the fan blows cold air throughout it, carrying away the heat and causing the refrigerant to condense. When certain particles blow over the coils, it can cause a thick dust accumulation, acting as an insulator, capturing the ventilation inside it. Thus, producing a substantial amount of freezing, and when combined with humidity, it creates an icebox effect which may need a comprehensive HVAC repair.
2. Collapsed Air Duct
The duct is the part of the unit associated with the consistent circulation of cool breeze around the property. If the rest of the system runs smoothly, but the aircon seems to be slightly off in providing cool air, tendencies are – the duct can be clogged, blocking the air movement to the coils. When this part collapses, it begins to freeze. There is not enough warm air to maintain an optimal temperature level. Because of this, the air stops streaming naturally and appropriately.
3. Congested Air Filter
Intake filters are a significant component of air conditioners between the house ventilation system and the unit itself, yet they are often overlooked and disregarded. This part operates 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 obstructed, it slows down the airflow, minimizing the blower’s functionality; for this reason, the coils will begin to freeze up.

4. Damaged Blower Motor
Air conditioners are set up with two varieties of motor, the spinning and blower motors. These parts matter significantly in the system as it turns on the fan, taking the cooled air to move along the unit, providing a cold ambiance around the house. Suppose, by any chance, the capacitor of these motors is damaged. In that situation, the fan will instantly stop blowing, ceasing the airflow over the coils. The coils will start to ice up when this happens, causing 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 giving off cool air as it goes through the compressors and evaporators. If the amount of cooling agent is minimized, warm air can not be converted into gas that heats up and drops the pressure. It would produce sufficient cold air to condense moisture for ice to build up, thus freezing the unit and crawling through the copper pipes.
6. Low Voltage Electricity
Frequently, we are occupied and attempting to look for the party responsible for device freezing. But what we actually don’t recognize is that electricity could likewise be a root cause. There are different air conditioners supplied on the market, and the voltage criteria rely on the equipment’s size. It is necessary to power up high system components to function accurately. So, if it is underpowered while the compressor is running, this can trigger an airflow freezing problem. In this situation, replacement may be needed. You can contact various HVAC service providers as they install air conditioners.
