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.

Solution: It is advisable to get the AC filter checked by UrbanClap and change it to a new one, if clogged.

 

2. Incorrect thermostat settings

1. The evaporator (inside unit)-absorbs heat from air around you and transfers it to the outside air conditioning unit.

2. Condenser (outside unit)- then condenses the hot air into cool air.
A clogged condenser will not allow a proper cooling of the air conditioning system. Debris and dirt will block even heat transfer.

Solution: Wondering how to fix AC? Clean the condenser and give it ample room to breathe, by removing weed and dirt surrounding it. To avoid heavy air conditioner maintenance charges get your air conditioning unit repaired and maintained regularly from UrbanClap.

A refrigerant is an important fluid that absorbs heat from the surrounding air, the absence or insufficiency of which might lead to your AC not cooling. If your air conditioning system is not cooling, it might be because the refrigerant is getting leaked. Get your air conditioning service done at regular intervals to ward off this problem.

Solution: It is possible to identify this issue, with signs, such as – hissing or bubbling noises, a buildup of ice on the outside unit. Once identified, call a professional and get this problem sorted.
