Guys, I did not understand what was meant by "compressor terminals blown out". Refrigerant left here "obviously," or there were actual holes near the teminals with some marks of oil beneath the compressors?
Husky, I would ask the clients about who and when installed the units, I surmise the units are of one and the same batch, "obviously", a defective one (probably it might be useful to look at the plates on the units). I heard LGs are not the best ACs on the planet.
