Hi Folks..
I'm having an issue with one of the AC systems in my house.. For some reasons only the upstairs unit seems to be leaking freeon.. But I've had a tech come over, and check for leaks, using a device amde by Infinicon-Tekmate, that emits a beeping sound when freeon is detected.. However, the tech wasn't able to detect any leaks using that.. Then he tried using the bubble detector solution, but wasn't able to find any leaks with that either.. He did this in both places, in the attic near the coil, and outside by opening the unit near the compressor..
He said that the only other place that the freeon could be leaking is in the pipes from the upstairs unit to outside, which would involve drilling a hole in the wall, pulling the pipe out, and replacing, and then repairing the whole in the wall..
However, when the tech replaces the freeon (with upto 2 pounds of freeon), the AC is ice cold again, and the last time he recharged it, it lasted for 2 weeks. Hopefully this time it will last longer, and the summer in the SouthEast will be over..
I've also replaced the filters and vacuumed the vents..
Has anyone seen this before.. where the freeon leaks over a period of say 2 weeks, but can't be detected, and upon recharging, it works fine.. for another 2 weeks. ?
Thanks in advance for your help..
