Most newer passenger car A/C systems do not hold much refrigerant (only 14 to 28 oz.), so you don’t want to add too much if the system is low. One can of R-134a typically holds 12 oz. of refrigerant.

What should AC pressures be on tractor?

Air conditioners work on a two-sided system: a high side and a low side. Low side runs between 10 to 30 PSI and high side between 150 to 285 PSI. The evaporator outlet should be cold to the touch, and duct temperature readings should be 35 to 50ºF.

What are the symptoms of an overcharged refrigeration system?

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;
