Noticing ice on the air conditioner signifies trouble with the cooling system. Being that it something that shouldn’t be ignored, we at GA HVAC Experts would like to share some common reasons of air conditioner units freezing up.
Low Refrigerant Levels in Central Air Conditioner
Refrigerant at low levels can develop ice on the unit. Due to the air conditioner managing pressure, the level of refrigerant inside your coils matters significantly. The collected heat is released when the refrigerant is compressed. The pressure drops when the liquid refrigerant turns into a gas. Afterwards, the compressor compresses the refrigerant and pumps it toward the blower fan inside the house again. Due to the lack of pressure, the conversion occurs too early when there is not enough refrigerant in the system. Eventually, the condensed moisture on the coils instantly freezes.
Bad HVAC Blower Motor
The blower motor is a major element of the cooling system. If the blower fan stops blowing, it causes the air to stop flowing quickly enough over the coils no matter if it’s the spinning motor itself or the blower motor’s run capacitor. When the air stops blowing, frozen coils develop. In the event the blower motor is in the process of failing, you will likely hear irregular or rattling sounds from your air conditioner.
Dirty AC Evaporator Coils
Layers of dust on the refrigerant coils become compacted with debris with the moist air condensing on the cold surface. Frozen coils develop as this thick blanket creates insulation that traps the cold inside the coils themselves.
Weak Air Flow
Reduced airflow is one of the primary reasons as to why the air conditioner unit freezes over. It can be challenging to pinpoint the cause as there are many problems contributing to the little airflow from the blower motor to the air intake. When the airflow in the system is impeded, it stops warm air from flowing over the coils while the compressor continues to run.
Poor HVAC Ductwork Design
Air ducts are essential in order to distribute the air throughout the home. Should the ducts be insufficient in dispersing the air, naturally, the airflow cannot reach the coils. Indeed, if the system is running smoothly air ducts that are flawed can cause your cooling system to lose the airflow. To keep them at the optimal temperature, the coils begin to freeze because there’s not enough warm air.
Low Voltage AC Fan
The air conditioner becomes a central part of your summer power since the air conditioner requires electricity to a variety of high-power components to run. When your fan or blower motor are under-powered while the compressor keeps running, problems can occur as well.
Failure to Change Air Filter
It is too common for homeowners to neglect the air filters. Filters that are over encumbered, the coils will freeze since the airflow is extremely restricted.

Finding the coils having been frozen, you need to promptly use the thermostat to shut off the system. Calling an expert as soon as the system is flipped off, you can prevent further damage as well as letting the ice flaw. Schedule an appointment with a professional as quickly as possible. If you find ice on your air conditioning unit, call GA HVAC Experts for assistance.
