Discovering the air conditioner has frozen is never good. Ice indicates a problem, especially since when it is present, the air conditioner is not operational. We at Ambient Heating & Air Conditioning would like to elaborate on the subject because this problem is more common than people realize.
Weak AC Airflow
The air conditioner will freeze for many reasons, and among the most common of them, is poor airflow. Being difficult to pinpoint the cause due to the number of causes of little airflow from the blower motor to the air intake, it generally stops warm air from flowing over the coils while the compressor continues run.
The air is distributed throughout the home with the air ducts. Should the ducts be not operating efficiently, the air flow is naturally blocked from the coils. Your cooling system loses the airflow if there is a collapsed or blocked air duct in your home, no matter if the rest of the system is running smoothly. Because there’s not enough warm air to keep them at the optimal temperature, the begin to freeze.
Bad Blower Motor
The blower motor impacts the performance significantly. Should the blower fan stops blowing then the air stops flowing quickly enough over the coils, whether it’s the spinning motor itself or the blower motor’s run capacitor. Once the air stops blowing, the coils freeze. In the event your blower motor is in the process of failing, you are likely to hear irregular or rattling sounds from your air conditioner.
Low Voltage Supplied to Fan
The A/C becomes a central part of your summer power when the air conditioner requires electricity to a variety of high-power components to run. While the compressor keeps running, issues can occur when your fan or blower motor are under-powered as well.
Clogged Up Air Filter
Though it is a big mistake, the filters are commonly neglected. The contaminates in the air is collected by filter’s design. The airflow is heavily restricted once they are filled to capacity, leading to the frozen coils.
AC Coils are Dirty
Layers dust on the refrigerant coils become compacted with debris, which is frequently dampened from moist air condensing on the cold surface. Frozen coils are often the result of this thick blanket creates insulation that traps the cold inside the coils themselves.
Low Refrigerant Levels
When the refrigerant lows, ice can form on the unit. Due to the A/C managing pressure, the level of refrigerant inside your coils matters significantly. After the collected heat is released, the refrigerant is compressed. The pressure drops once the warm air converts liquid refrigerant into a gas. The refrigerant is compressed by the compressor, and it pumps it toward the blower fan. Due to the lack of pressure, the conversion occurs too early in the event there isn’t enough refrigerant in the system. Without enough cold in the moment, the condensed moisture on the coils instantly freezes.
