BMW air conditioner sometimes cooling and sometimes not is mainly due to air conditioning abnormalities. Reasons for air conditioning installation: Cleaning issues: Sometimes, long-term lack of cleaning can also affect the cooling effect of the air conditioner. The air conditioner also needs cleaning and maintenance. The outdoor unit, being exposed to the outside for a long time, easily accumulates dust and debris. If not cleaned for a long time, it will affect the machine's heat dissipation performance, leading to poor cooling effect. The indoor unit is related to human health. If not cleaned for a long time, it can breed bacteria, pollute the air, and cause illness. The filter screen of the indoor unit, if not cleaned for a long time, can also be clogged with dust, resulting in the air conditioner not cooling. Insufficient air conditioner horsepower: If the ventilation pipe of the air conditioner is installed too long, it may lead to poor heat transfer from indoors to outdoors, resulting in less obvious cooling. It's best to find a better position to reinstall, aiming to minimize the length of the ventilation pipe. If the air conditioner operates normally and everything else is intact, but the room does not feel cold, and cold air is only felt when close to the air conditioner's vent, it is likely due to the air conditioner's insufficient horsepower relative to the room's size. In this case, it's best to replace it with an air conditioner with greater horsepower.
