Your suction pressure will always vary depending on many variables. What type of freon??? If you find your freon type on a PT CHART(PRESSURE/TEMPERATURE), 65-70 psig will have a temp that is 38-41°f. Most evap coils should be a bit warmer but not much. BUT, again variables! Coils are clean, indoor temp, blower speed, return air opening, supply ducts. Also superheat should be a factor. If you have 65-70psig, that freon temp(per pt chart r22) is 38-41°f, then using a temp sensor/meter to measure the actual temp of the suction line. Subtract 38-41 from the actual temp and that give us a superheat reading. This # should be around 8-12°. But again variables! If the unit has an expansion valve? Seems like you are close if its r22.
SOURCE: No cooling, suction pressure reads vacuum Split AC
The unit is restricted, reprocess the system, flush and vacuum it thoroughly.
SOURCE: what is the ideal gas pressure in carrier split ac
No such thing. Pressures depend on ambient temperatures, superheat and sub cooling.
SOURCE: Hi I have 1.5 ton samsung split AC. the problem is...
the water comes from the coil, start there make sure there is no obstruction coming out to your condensate line and make sure its properly pitched.
SOURCE: split ac not cooling
