I wonder why in cold seasons, when a heating mode is switched on, the air conditioner starts producing warm air after a while? Sometimes the pause is rather long and I have the impression that my air conditioner cools a little bit. May it be defective?

Answer: Everything’s all right. Moreover you are lucky to have got a modern model with Hot Start mode. Such type of air conditioners warms the outdoor unit first, before operating at subzero temperatures, in order to prevent ice formation. It is really turned on in cooling mode but the fan is switched off at this moment, so you can feel cold only while taking your hand closely to the indoor unit.
