a the time of install the guy said he checked the line with putting nitrogen in. does that still mean that its still not clean???
and why the sudden change with putting more freon in??
i really appreciate this there is just too many bad tech out there
could the new coil or condenser jeopardized already from that
i'll tip you @the end.
if this procedure gets done right (start from beginning evacuate etc and clean) should I I still worry about the soft soldered joints and leaking? I just found out that it is now shooting cold air again. When you say burnt out compressor does that mean complete failure or will it work again.
Since, we had the line leak tested for 24 hours with no leaks. Once reconnected with now braised joints it was again leak tested as a whole. Result--no leaks. Then system was vacuumed for 4 hours, recharged with new freon. The gauge continues to read too low on the low side. The system is working right now with cool air showing 55 degrees or less out of the vents but what is causing the low pressure readings.
