Once the air gets to the condenser, it will remain at its top and not condense. The subcooled liquid seal at the condenser’s bottom will prevent the air from passing out of the condenser. This air and water vapor will take up valuable condenser surface area and cause high-head pressures.

What causes high head pressure and high suction pressure?
Overcharging of refrigerant, liquid slugging of the compressor, oil contamination and other sources can damage compressor valves. Refrigerant overcharging will show up as high head pressure, normal suction line pressure, normal superheat, high sub-cooling.
Does low refrigerant mean leak?
AC refrigerant circulates in a closed system and continually cycles between a liquid and gaseous state to transfer heat without losing volume. This means that low refrigerant in your air conditioner is a sure sign of a leak.
What causes high head and high suction pressure?
Overcharging of refrigerant, liquid slugging of the compressor, oil contamination and other sources can damage compressor valves. Refrigerant overcharging will show up as high head pressure, normal suction line pressure, normal superheat, high sub-cooling.
Do Line Restrictions Cause High Head?
What happens if refrigerant is low?
Frozen Refrigerant Lines: When the system is too low on refrigerant, the evaporator coil can get too cold. This causes ice to build up on the coil itself, but also on the surrounding components of your air conditioner. If you notice an ice build ups on your air conditioner, this is most probably the reason.
How do I know if my refrigerant level is low?
- It takes a long time for your home to cool off. ... - Vents are not blowing cool air. ... - The temperature you set is never reached. ... - Your electric bill is higher than normal. ... - Ice on refrigerant lines. ... - Water leaking around heater. ... - Hissing or bubbling noise.
What causes high head pressure in refrigeration?
Once the air gets to the condenser, it will remain at its top and not condense. The subcooled liquid seal at the condenser's bottom will prevent the air from passing out of the condenser. This air and water vapor will take up valuable condenser surface area and cause high-head pressures.

What are two causes for high head pressure readings on a system?
- Dirty Condenser Coils. Your coils in your air conditioning system can become dirty over time. ... - Bad Fan Motor. You might notice that you have high head pressure if you have a bad fan motor. ... - Refrigerant Issues. ... - Non-Condensing Gases.
What is the most common cause of high head pressure?
Bad Fan Motor This is actually the most common issue that causes high head pressure. You can have a bad fan motor due to a few different reasons. Your fan blades naturally wear down over time. The process of them wearing down can be expedited by debris finding its way into your air conditioner's outside unit.
Ac Pressures Too High, Common Cause
Will low refrigerant cause high head pressure?
The excess refrigerant will accumulate in the condenser, causing high subcooling and high head pressures. If a TXV receiver system is restricted in the liquid line, most of the refrigerant will accumulate in the receiver, with a bit in the condenser. This will cause low subcooling and low head pressure.
What causes low suction and high head pressure?
The main reasons your compressor will have simultaneously low head pressure and high suction pressuresuction pressureIn refrigeration and air conditioning systems, the suction pressure' (also called the low-side pressure) is the intake pressure generated by the system compressor while operating.https://en.wikipedia.org › wiki › Suction_pressureSuction pressure - Wikipedia is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line.
