The pressure for R22 refrigerant varies depending on the temperature and phase of the refrigerant. For example, at 40°F, the pressure can be around 60 psi on the low side and 185 psi on the high side. It's important to consult a pressure-temperature chart for specific values.

R22 gauges are designed for use with R22 refrigerant, and while they can technically be used to read the pressure of R416A, the accuracy may not be reliable. R416A has different pressure-temperature characteristics compared to R22, so using R22 gauges could lead to misinterpretation of the readings and potentially improper servicing. It's advisable to use gauges specifically designed for the refrigerant in use to ensure accurate measurements.

Mixing R22 refrigerant with R438A is not recommended. R438A is a replacement for R22, but it has a different composition and properties. Mixing refrigerants can lead to reduced efficiency, potential equipment damage, and difficulty in servicing the system. It's best to fully evacuate the system and charge it with the appropriate refrigerant.
The cost of 125 pounds of R22 refrigerant can vary depending on market prices and supplier rates. On average, you can expect to pay anywhere from $50 to $100 per pound for R22 refrigerant. Therefore, the total cost for 125 pounds of R22 could range from $6,250 to $12,500.
Using R134a instead of R22 in a window AC unit is not recommended, as they have different properties and pressure requirements. R22 is a high-pressure refrigerant, while R134a operates at a lower pressure, which can lead to inefficiencies and potential damage to the system. Additionally, the oil compatibility and system design may not support the use of R134a. Always consult a professional or refer to the manufacturer's guidelines before making any refrigerant changes.
A 2-ton air conditioner typically contains around 4-5 pounds of R22 refrigerant.
