Ice formation in AC

One of the main reasons behind air conditioner is not cooling properly is ice formation in split ac indoor unit or window AC as it leads to the reduction of air flow.
 

Problem :

Dirty filters, coils and below par working fans are the major reasons for ice formation on air conditioners. Regular air flow inside your air conditioner is necessary in order to maintain the temperature of cooling coil above freezing point. But if this airflow gets disrupted due to dirty filters or coils then lot of moisture gets stock up inside the air conditioner which in turn results ice formation in split ac indoor unit.

 

Solution :

So, to avoid this problem, all you need to do is clean your air filter from time to time. Read more about what causes ice to build up on an air conditioner.

 
 

Low Refrigerant Level

Problem :

Low refrigerant level is one of the major and common problems for your window AC not cooling enough or Split AC not cooling enough. The purpose of coolant is to circulate through the evaporator coils and cool the air flowing over it and thus sends cool air into the room.

There can be basically 2 reasons behind Insufficient refrigerant level problem:

  • AC gas leakage problem
  • Devaluation of AC gas with time

Both of them causing the air conditioner not cooling properly.

 

Solution :

For AC gas filling or ac gas top-up you require professional help who will find why air conditioner not cooling and repair the ac gas leak and then refill the ac refrigerant in the AC unit.Get your air conditioning maintenance done at regular intervals for hassle free summers.

Degrading Of Air Conditioner with Time

degradation of air conditioner with time

 

Problem :

Just like humans even machines tend to lose their efficiency with age. The older your air conditioner the lesser will be its efficiency which will reduce its cooling capacity. According to ASHRAE ( American Society of Heating, Refrigerating and Air Conditioning Engineers ), an AC reduces its efficiency by 7% in the 1st year, 5% in the 2nd year and 2% every year in the following years.

For Example, if an air conditioner is 20 yrs older or more, then its efficiency of cooling might be decreased by 40%. So older your AC then lesser is the efficacy.

 

Solution :

The best solution to the problem “why air conditioner is not cooling“ can be time to time regular servicing of AC as it will surely extend the age of your air conditioner.

Problem :

When there is some defect in ac fan or its blades are damaged then it may result in ac is working but not cooling problem. As the outside fan is responsible for transmitting heat from your house to outside air. If the outside fan doesn’t perform correctly it will end up overheating the AC compressor and proper heat transfer will not take place resulting in air conditioner blowing hot air problem.

 

Solution :

Check that the blades are not damaged. If blades are damaged than a well qualified AC repair technician will be needed to identify and resolve the problem.

 

Clogged Air Filters

blocked ac filters

 

Problem :

Clogged air filter is one of the main reasons behind ac not cooling enough. Clogged air filter prevents the air from flowing properly through the air conditioner which blocks the functioning of your AC unit.

The improper flow of air restricts or limits the cooling capacity of your AC resulting in air conditioner not cooling enough.

 

Solution :

Try to clean the filter to remove the wet remains from the air filter. It is recommended that you clean your air conditioner filter every two weeks. But if you think that it’s not possible to clean the air filter then you can have them replaced.

 

Dirty Coils

dirty coils in air conditioner

 

Problem :

If your air conditioner not cold enough, the condenser coils might be dirty. As we know, in all air conditioners, the condenser plays the role of radiator that dissipates heat. In order to dissipate heat outside the condenser coil must be thoroughly clean.

So, if the coil is dirty, the heat isn’t dissipated outside completely which prevents the AC unit from getting cold enough and it will not be able to cool the room.

 

Solution :

Solution to what to do when ac is not cooling problem is that, the condenser coil must be cleaned regularly. As the coils get dirtier day by day, the air conditioner becomes less efficient, as a result, cooling power of AC is reduced.

 

Damaged Compressor

ac compressor not working problem

 

Compressor is the most important part in your air conditioner “Heart of AC”, which is responsible for cooling your room. No air conditioner can work without AC compressor; it is the heart of your home’s air conditioning system.
 

Problem :

An AC compressor moves the refrigerant through the machine, cooling your home in the process and if it stops working then your AC will not provide cooling at all. So if your ac is not cooling then the compressor might be damaged.

Also, there can be other problems related to compressor such as – voltas ac compressor not starting, split ac compressor not working, ac compressor working but not cooling, window ac compressor not turning on, ac compressor not working.

 

Solution :

It should be repaired ASAP by a AC repair professional. Any fault in AC compressor will lead to stopping of cooling process in AC unit, as the compressor will not be able to circulate the refrigerant/coolant through the evaporator & condenser coils and thus AC will fail to cool.

 

Faulty Thermostat or Incorrect Thermostat Setting

how to change ac thermostat settings

 

Thermostat functions to sense the temperature of the room and then sends the signal to AC compressor to either start or stop the cooling cycle.
 

Problem :

In case there is a fault in thermostat then the signal will not be sent to compressor which will lead to AC not cooling at all or it may keep cooling continuously. Also incorrect setting of the AC thermostat can be the reason your split or window AC is not cooling.

 

Solution :

Try to change AC thermostat setting from “Auto” mode to “On” mode. Even after changing the mode does not solved the problem, than the thermostat needs to be replaced. Read more about air conditioner troubleshooting.

 

Fault in AC Parts

Problem :

Solution :

Faulty parts need to be replaced or repair. Hire an experienced professional to fix this for you.

 

Undersized AC

what should be the size of ideal ac

 

While buying an AC, one of the most important things you should ask yourself is how big an air conditioner do you need for your room.
 

Problem :

If a small air conditioner is installed in a huge room then it will get difficult for AC to cool the room in summers when the temperatures are extremely high.

 

Solution :

For an AC to cool your room at an optimum level it is very necessary that size of AC is according to the size of your room.

 

Incorrect AC Installation

It is one of the common reason for ac not cooling and sometimes we neglect it which in turn hampers the cooling capacity of AC.
 

Problem :

If the outer part of Window AC or the outdoor unit of Split AC is coming in direct contact of sunlight and there is excessive rise in surrounding temperature, then the cooling efficiency of air conditioner gets affected and sometimes after a point AC compressor stops work. Read more about Direct sunlight on air conditioner outdoor unit problem.

 

Solution :

So, whenever you are getting your AC installed, always make sure the outer part or unit is not directly facing the sun.

Problem :

As the heat intensifies, we tend to overuse the air conditioner to keep our homes and offices cool which can adversely affect the efficiency of an air conditioner. An air conditioner collects dust and debris during operation which gets deposited in the ac unit preventing it from cooling your room properly.

 

Solution :

It is always recommended to have AC maintenance services on a regular basis so that your air conditioner provides you optimum cooling all summer. Thus, getting professional AC servicing once in 3 months is always necessary as it ensures the proper functioning of your air conditioner and it’s parts.
