WebWAY too low. Your coil is going to freeze eventually. You are most likely low on R22. You leaking homie. You got some choices to make. Find it, patch it, pay out the ass for some r22. Or take that thing out back and shoot it and get a new unreliable 410a unit. 38 psi is really low. Should be above 65 at least. WebTake the suction pressure and use the pressure/temperature chart to convert it to temperature. Let’s say the suction pressure is 60(Psi) which converts to 34F. And assuming that the suction line temperature is 44F. Then to get superheat we just get the difference between the two temperature readings. In this case, we have 10F of superheat.
