Make your job easier with our handy refrigerant pressure temperature HVAC app with R-22 included. R22, also known as HCFC-22, is a colorless gaseous hydrochlorofluorocarbon refrigerant commonly used in HVAC systems for residential air conditioning and refrigeration. Introduced in the 1970s, R22 became widely used as a refrigerant due to its stability, safety, and energy efficiency properties. However, R22’s chlorine content also makes it ... R22 Pressure: R22 operates at lower pressures compared to 410A. This means systems designed for R22 cannot handle the higher pressure of 410A without modifications. 410A Pressure: 410A operates at a higher pressure, leading to more efficient cooling cycles. However, this requires stronger, more robust components in the AC system.

Jake Clark, certified flight instructor, discusses the oil pressure gauge on the R22. Higher than that. Need suction and liquid line temp to, cant diagnose off just pressures. RIP Ozone. Please call a real pro in you have bo business being on your own if you dont know what superheat and subcooling are.

R22 has a very similar boiling point to R290 (-41.4°F to 44°F; that’s only a 2.6°F difference). At 100°F, however, the pressure of R22 is 195.9 psig and the pressure of R290 has a pressure of 174.3 psig (check the R290 PT chart below). This is a 20+ psig difference and you will easily tell if you have an R290 or R22 freon.

The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.Higher than that.
