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.

6 Reasons why your AC is not cooling

Below are some of the major reasons why your Air conditioning unit is blowing hot air:

1. Dirty air filter

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 Urban Company and change it to a new one, if clogged.


2. Incorrect thermostat settings

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.

Solution: Always keep the AC thermostat on “Auto” mode instead of “On” mode. This is a common reason why your AC is not cooling.

3. Dirty outside unit

Reason why an unclean outside unit hampers the working of your AC, it is important you understand how air conditioning works.

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 Urban Company.


4. Faulty motors

If the motor of the fan is either broken or faulty, the outdoor unit will be unable to dissipate heat, thus interfering with the cooling ability of an air conditioning unit.

Solution: This problem of your split or window AC not cooling is best handled only by a professional. You can hire professionals from Urban Company for the same.

5. Low refrigerant level

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.

6. Damaged compressor

A compressor is a vital component of an air conditioning unit, as it manages the flow of refrigerant between the evaporator and condenser. Therefore, a damaged condenser cannot cool air well enough.

Solution: A damaged compressor needs a replacement. Hire an experienced professional to fix this for you.

To keep you AC working properly all throughout it is advisable that you get your air conditioning unit serviced and maintained by an expert. Wondering how often should you have your air conditioner serviced? Get it done every 3 months to enhance the efficiency and output of your air conditioning unit.
