AC Not Working at Idle

That chart looks like every chart I’ve ever seen. 35-55 on low side and 325 max on high side. I understand equalized pressure reading, just never have bothered on vehicles. Only have seen HVAC Techs bother with it on a house system.

 

The licensed HVAC Techs I know went through Apprenticeship programs. Starting with Electrician training then halfway through split off into HVAC. It took them 4 yrs.

 

Hes right you cant go by a chart, theres way to many variables besides temp.

 

Humidity will raise pressure, also. Best to check on hottest and most humid days, in a perfect world.

 

you will get 110 on both sides

 

Without compressor running.

 

without gauges and compressor on you will get 110 on both sides

 

OK

 

What was the problem with the A/C after all ?
