To determine air flow through an A/C unit, a technician needs a digital thermometer and humidity tester to test the temperature coming out of the vents and identify common problems causing temperatures that are 3 degrees warmer or cooler than expected. Problems causing warmer temperatures include low refrigerant, a weak compressor, or duct leaks, while problems like a dirty filter or coil can result in temperatures that are 3 degrees colder.
