Question about Whirlwind FH-778 Air Conditioner
How much freon belong in a central air condition
That depends on the size of the unit and lenght odf the line set.. to give you a general answer your suction pressure should be about 70 PSIG and you liquid line (small line) should be between 245-265 depending on the outdoor temp you will need a set of freon gauges to check this these readings are for an R-22 system if you have R-410a the readings will be much higher
