Delta T on good running A/C unit

Hello, What is typical reading of Delta T when system is running well? What is low limit which needs attention. Just starting the unit for the season. TIA,

If you mean the cold air coming out vs the warm air going into the return, I'd say high teens to low 20's delta. But there are probably a lot of variables.

The cold air should be 15 to 20 degrees colder than the warm air going into the returns.

If it's very humid, there will be much less temperature difference.

Hi, Thanks. It measures 71 and 50 deg. OK for another season I guess?

As long as it's 71 going in and 50 coming out, yes. If it's the other way around, then I think something is wrong.....

Just for giggles, get the $89 special and see what they break. On second thought....
