Customer Question

Glenn: With an r22 unit what are my ideal temp/ pressure readings?
JA: Thanks. Can you give me any more details about your issue?
Customer: Ambient temp 90f Guages reading 68 psi on suction side and 260 psi on my high side, I believe that my refrigerant is low. Would my assumption be correct. The system is a residential unit.

Pressures are going to vary slightly by unit, but ideally around 72psig and 250 psig. with a temp drop across indoor coil of 18 to 20 degrees.

1.Have you checked to verify indoor and outdoor coils are clean as well as filter?

2.Have you taken a temp drop across indoor coil?

3.Is large copper line "beer can cold?"
