Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Relative Humidify
After running for prescribed length of time on recirculated air and maximum cooling, relative humidity will remain at approximately 35-40% regardless of ambient temperature or humidity. In areas of high humidity, thermometer and gauge readings may approach but not reach specifications listed even though system is operating in a satisfactory manner. However, low pressures that are too low may result in ice gradually forming on evaporator fins resulting in insufficient or no cooling.
