Have you ever gone through the problem of your air conditioning unit blowing out hot air instead of cooling your room? This issue can get on our nerves especially during the hot summers. There are many reasons why your air conditioning system is not in its proper state. Read on to find out how to fix AC and the 6 common reasons why your AC is not cooling your room.

the most common reason why your split and window AC is not cooling is because of unclean air filters. If the AC filter is unclean or clogged with dust and dirt, it might result in various problems. It could interfere with the proper working of the thermostat. Dirt in the AC filters block the passage of cool and warm air  inside the ducts. It could also make the evaporator coil freeze, thus blocking the passage of cool air from the outlet.

You need to check the working of the AC thermostat if your split or window AC is not cooling. It is a problem if your air conditioner unit blows out cool air and then lukewarm air. When faced with such a situation, turn the thermostat settings to auto mode. This way the fan works only when the air is being cooled.
