Air conditioners are mounted to locations where the sun’s heat predominantly prevails and emits cold air. It generates numerous benefits to the environment and people’s health, from offering safety and superior quality of life in our own homes. Having said that, as aircon might seem beneficial, it can also be linked to a variety of system issues. Among which is the probability of freezing up. Below are the reasons why this reality takes place.
Reasons for Air Conditioner Freeze Up
1. Blocked Compressor Coils
Compressor coils are significant as the center of any air conditioning unit as it pumps the cooling agent throughout the system. These are designed to supply adequate surface area for the heated icebox to move along as the fan blows cold air across it, carrying away the heat and causing the refrigerant to condense. When various particles blow over the coils, it can cause a thick dust accumulation, acting as an insulator, trapping the ventilation inside it. Therefore, producing an excessive amount of freezing, and when combined with moisture, it creates an icebox effect. In this situation, schedule for an All American Heating & Air service for detailed unit maintenance.
2. Collapsed Air Duct
The duct is the part of the unit involved in the consistent airflow of cool breeze around the property. If the rest of the system runs smoothly, yet the aircon seems to be a little off in providing cool air, possibilities are that the duct can be clogged, blocking the airflow to the coils. When this component breaks down, it begins to freeze. There is not enough warm air to maintain an optimal temperature. Because of this, the air stops flowing normally and correctly.
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 neglected. This component operates to capture various debris, particulates, and pollutants, consisting of dust, molds, pet dander, and fungal spores, keeping the air purification and compressor coils clean. When this component is obstructed, it slows down the air movement, minimizing the blower’s functionality; hence, the coils will start to freeze up.
4. Damaged Blower Motor
Air conditioners are installed with two types of electric motor, the spinning and blower motors. These parts matter significantly in the system as it activates 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 case, the fan will instantly stop blowing, ceasing the airflow over the coils. The coils will begin to ice up when this occurs, causing uneven and rattling sounds.
5. Inadequate Refrigerant
Refrigerant is a chemical compound used for aircon that absorbs the heat from the environment and manages the pressure, thus releasing cool air as it goes through the compressors and evaporators. If the amount of the cooling agent is minimized, warm air can not be converted into gas that heats up and drops the pressure. It would create sufficient cold air to condense moisture for ice to develop, thereby freezing the unit and crawling through the copper pipes. When this happens, don’t hesitate to visit several HVAC repair websites like allamerican-nc.com to schedule a cleaning and repair appointment.
6. Low Voltage Electricity
Frequently, we are occupied and attempting to search for the party in charge of device freezing, yet what we literally don’t know is that electricity could likewise be a culprit. There are various air conditioners supplied in the market, and the voltage requirement relies on the overall size of the equipment. It is necessary to power up high system components to function correctly. So, if it is underpowered while the compressor is running, this can cause an airflow freezing problem.
