High Subcooling is an indication that more than the designed amount of refrigerant is “backing up” or “packed” into the condenser. This can be caused by overcharge, restriction (such as a contaminated line drier or kinked liquid line), or an undersized or failing closed metering device.

What happens if subcooling is too high?
If the subcooling is too high, the system will be overcharged, reducing performance, efficiency, and ultimately damaging compressor valves and start components.
What would cause high superheat?
Excessive or high superheat is an indication of insufficient refrigerant in the evaporator coil for the heat load present. This could mean that not enough refrigerant is entering the coil or this could also indicate an excessive amount of heat load on the evaporator coil.
Will low refrigerant cause high superheat?
Excessive or high superheat is an indication of insufficient refrigerant in the evaporator coil for the heat load present. This could mean that not enough refrigerant is entering the coil or this could also indicate an excessive amount of heat load on the evaporator coil.
Causes For High Condenser Subcooling (Hvac)
What can cause high condenser subcooling?
Excessive subcooling means the refrigerant was cooled more than normal. Possible explanations include overcharging, a restricted metering device, maladjustment (underfeeding), or faulty head pressure control during low ambient conditions.
Is High subcooling overcharged?
High condenser subcooling: Because of the overcharge of refrigerant in the system, the condenser will have too much liquid backed up at its bottom, causing high subcooling. Remember, any liquid in the condenser lower than the condensing temperature is considered subcooling.
What does high subcooling indicate?
High Subcooling is an indication that more than the designed amount of refrigerant is “backing up” or “packed” into the condenser. This can be caused by overcharge, restriction (such as a contaminated line drier or kinked liquid line), or an undersized or failing closed metering device.
Liquid Line Restriction! What Happens To High Side Pressure & Subcooling?
What causes high subcooling and normal superheat?
If superheat is high and sub-cooling is high: Could have blockage in coil, orifice or line set. If superheat is low and sub-cooling is low: Orifice could be too big, there is no orifice in the unit of the orifice is stuck and refrigerant is by-passing it. Superheat is telling you what is going on in the evaporator.
What causes high subcooling and high superheat?
If superheat is high and sub-cooling is high: Could have blockage in coil, orifice or line set. If superheat is low and sub-cooling is low: Orifice could be too big, there is no orifice in the unit of the orifice is stuck and refrigerant is by-passing it. Superheat is telling you what is going on in the evaporator.
Subcooling = Stacking Liquid Refrigerant (What Subcool Really Signifies)
Does a dirty condenser cause high subcooling?
Even the subcooled liquid temperature coming out of the condenser will be at a higher temperature when the condenser is damaged, fouled, or dirty.
What happens if your condenser is dirty?
Because dirty condenser coils make it difficult for your air conditioner to cool your home, you system will have to work much harder and longer to try and compensate. This leads to high cooling bills because your system will have to consume much more energy than usual. Your system might break down.
