Inadequate cooling after refilling of Window AC
Are you facing the problem of inadequate cooling after refilling of Window AC? Ask our technical experts for the best solution.
Gas from my Window AC had leaked. The Mechanic, to check for leaks emptied the gas and refilled air to say 50PSI and left it for 24 hours to check of there was any drop in pressure.
Next day, as there was no drop in pressure. The Mechanic refilled it with gas but Ac is not cooling as earlier.
My suspicion is that, Mechanic did not remove the air totally and refilled gas, hence, I am having mixture of gas and air, because of which ac is not cooling the room properly. The ac is running perfectly and only problem being, that it is not cooling the room as before.
I would like to know, if my suspicion is right or wrong, in this regard. Mechanic is adamant that, if one mixes, gas and air, ac compressor will explode.
