A/C Diagnostics 101: The Value Of Scanners
Leave it to the manufacturers to take a simple thing like heat and air conditioning and turn it into an electronic jungle of wiring, sensors and computer components. HVAC units have come a long way from when I started in the business. Not that I want to dwell on the past, but it might be a good idea to make sure we understand the basics before diving into the problem of today’s systems. I always feel that if I understand a system fully before doing any repair work, I’m more likely to get it right the first time.
A/C Compressors Take A Pounding
The A/C compressor is a pump that compresses and circulates refrigerant within the A/C system. Some have pistons inside while others have rotating vanes on an eccentric or a pair of metal scrolls or spirals around an eccentric. Many late-model vehicles have “variable displacement” compressors that change the piston stroke to increase or decrease the volume of refrigerant flowing through the system. Some of these run continuously instead of cycling on and off like conventional A/C compressors.
