The short answer to your question is that the high and low side pressure for R22 refrigerant is 250 and 68 psi at 35 degrees C, respectively as shown below.
Simply so, What is the suction and discharge pressure for R22? For example, a high-efficiency condensing unit using R-22 typically operates with a suction pressure of about 68 psi and a discharge pressure of about 250 psi at an outdoor temperature of 95°F.
How do you tell if a R22 system is overcharged? The most common indicators of an overcharged system are:
- Increased pressure throughout the system, characterized by high head pressure and high suction pressure with low suction superheat;
- Increased flooding of refrigerant to the compressor during off-cycle, which may cause flooded starts;
Subsequently, How do you charge a R22 unit?
What should the high and low side pressures be?
These pressures will vary depending on ambient temperature (temperature of the outside atmosphere), but ideally, you will want to see your low side pressure between 30-40 psi and your high side pressure between 150-175 psi.

What should my Freon pressure be? Most technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions.
What should my AC pressures be?
If you think that you have an issue with your A/C system but you are not sure which component is causing the malfunction it is a good idea to hook your compressor up to a pressure gauge. An A/C System that is working properly should have 150 PSI on the high side and 30 PSI on the low side.
What should the low side pressure be on R22? The short answer to your question is that the high and low side pressure for R22 refrigerant is 250 and 68 psi at 35 degrees C, respectively as shown below.
What should refrigerant pressures be?
Most technicians in the HVAC field know the normal range of operation for the low-pressure side of an air conditioning system. This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions.
Are 407C and R22 pressures the same? (10) informed that R407C had higher pressures than R22 with discharge pressure of R22 being at 2193 kPa for the lower outdoor conditions and 2784 kPa for the higher outdoor conditions. For all operating conditions, the discharge pressure of R-407C is varied in the range 11-13% higher than R22.
What is saturation temperature of R22?
A refrigeration evaporator is operating with R-22 refrigerant at 69 PSIG suction pressure; its saturation temperature is 40°F. This is the temperature at which the refrigerant evaporates from a liquid into vapor.
How do you read a refrigerant chart?
What should the AC gauges read? What are normal AC gauge pressures when the system is running? Generally speaking, you want around 27-psi on the low side and 200 on the high side.
Why is the low side pressure high?
If The Low Side Pressure Is Too High And The High-Pressure Side Is Normal… … In that case, it might not cool the refrigerant sufficiently, meaning the pressure is still higher than it should be after it’s passed through the evaporator. The other potential reason for this situation is an overcharged system.
How do you read a refrigerant charging chart?
How do you read AC pressure?
Do you charge AC on high or low side?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
Will low refrigerant cause high 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.
What are normal operating pressures for R-410A?
System Pressures
A normally operating R-410A system with the same condensing temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.
What color is the high side gauge? Manufacturers color-code the hoses to distinguish between high pressure and low pressure. Low-side hoses are blue while the high side is red.
Can I drop 407C on top of R22?
Mixing R22 with R407C or any other refrigerant. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
What is the pressure difference between R22 and R410A? R-22 has a typical high-side pressure of 260 psig, while R-410a’s is 420 psig. technicians must take care in the handling of R-410a and the Poe oil in the system, as both have a much greater affinity to water than R-22 and mineral oil.
What is the best drop in replacement for R22?
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.
