Problem: Please explain how to read air conditioner refrigeration gauges?

Problem: I would like to check the charge on my air conditioner or heat pump unit. I purchased some air conditioner freon refrigerant gauges, but have no idea what all the numbers pressures and temperatures mean. Please explain how to read the HVAC freon air conditioner gauges.  Please explain what all the numbers and temperatures mean?

Answer: I found a great YouTube video made by AC Service Tech LLC that describes how to read manifold air conditioner refrigeration gauges when using either R22 or 410A refrigerant. AC Service Tech explains what things affect the pressures on the low and high side gauges. If you have any questions please email us anytime.
