The very first factor for your a/c system freezing is probably the most typical. The freon pressures in your system count on the absorption of heat in the evaporator area. This is generally transferred from air that is drawn in from your house into the air handler unit and throughout the evaporator coil. With a loss of air circulation comes a drop in temperature level listed below freezing at the evaporator section triggering the water particles in the air to form frost on the indoor coil which ultimately develops into a layer of ice. The most typical cause for air flow loss are listed below.
1. Filthy filter at the return air duct on the system, or too limiting of a filter (filters have a MERV ranking, the greater the ranking the smaller sized the particle it will filter).
2. Burned out Indoor Blower Motor, or Motor that has too weak a capacitor to begin the motor. Oftentimes a humming noise can be heard at the air handler unit.
3. Bent, or Broken Blower Wheel unable to turn and provide air flow. An unclean blower wheel will typically trigger motors to stop working prematurely and will not move enough airflow.
4. An unclean evaporator coil, generally caused by the absence of a filter at the return, or too infrequent altering of the filter (very typical) This needs the evaporator to be pulled and cleaned expertly.
5. Incorrectly sized duct work, crushed or collapsed duct, insulation blown loose in system obstructing air flow. Poorly installed duct work.
6. Blocking of the return air grille either with furnishings or other blockage.
7. A lot of Vents or Registers closed.
The second classification is refrigerant loss. This is another really common cause for a/c systems freezing over. Each system is charged with an exact quantity of refrigerant or freon that is used to transfer heat from your house. Age of a system, inappropriate installation, level of acidity of refrigerant, or manufacturing defects can trigger systems to leakage refrigerant. The size and intensity of the leak is circumstance dependent. Loss of pressure in the system cause the temperature level of the refrigerant to drop listed below freezing temperature levels and form ice on the evaporator coil and travel outside to the condenser by means of the copper lineset. In uncommon cases overcharging a system might lead to no superheat and the cooling unit to freeze over.

Other reasons for an a/c system freezing are mechanical related and are listed below.
1. A clogged liquid line filter drier. Which is usually a result of a poor quality installation, and improper evacuation throughout installation of a central heating and air system.
2. A kink in the liquid line, or limitation in the system at the TXV (thermostatic expansion valve) near the entrance to the evaporator coil.
3. Liquid line valve not totally opened.
4. A constraint in the metering gadget which can either be a fixed orifice, capillary tube system, or TXV with a malfunctioning power head. This can also be connected to bad installation practices and lack of filtering gadget installed in system.

The last cause for an a/c system freezing over is temperature level. When we are referring to temperature in this situation we are generally speaking about the outside ambient temperature level. A low outside ambient temp can trigger the pressures in the system to drop listed below regular and trigger freezing of the a/c unit. This problem is generally fixed with a lockout device set up on the air conditioning unit by the manufacturer. Not all systems are equipped with this kind of control though. Normally running you're A/C system in outside ambient of below 60 degrees is not suggested. Freezing can likewise happen when the indoor temperature at the thermostat is set too low. This puts unneeded wear and tear on the system. On a property system the indoor temperature should not be set listed below 68-70 degrees unless geared up with controls that avoid a freezing over scenario.
When the cooling system freezes over it can trigger the freon to go back to the compressor in a liquid form and cause slugging of the motor. Modern scroll compressors are much better geared up to manage this scenario than older style systems. Nevertheless, it can still cause damage to the system and should be assessed by an expert if it ever occurs.
