Top 14 Common AC Problems In Summer

AC is our saviour from the scorching heat and it can never be neglected for that. While you never neglect your AC, your AC might be suffering from many common AC problems and you don’t even have the slightest idea about it. Don’t you worry, as these AC Problems can be easily fixed at home? AC is important and there are no two opinions about it. But to make your AC last longer you need to go an extra mile for that and the only way to do this is by taking care of your cooling device.

Top 14 Most Common Summer AC Problems

In this very article, we’re going to talk about the top 7 most common summer AC problems one may face and the possible remedies for the same (that can save you from sweating!).

1. Blocked air filters

Clogged air filter/air drain is one of the most common AC Problems one faces with air conditioning mechanisms. It happens with continued use of the air conditioner without its cleansing and maintenance. However, the AC Problems arising due to this perfunctory behaviour can be major, from system failures to meagre cooling.


  • Keep a timely check on the working unit.
  • Clean the air filters quarterly in a routine manner.
  • Contact the Ac Repair in Bhopal technician for aid at the very start of the issue to avoid ‘breaking’ of the ac.

    2. AC blowing warm air

This is also a frequent issue one faces with ACs when their ‘cool air’ throwing AC starts blowing ‘warm air’. Now, this is a condition that can arise out of nowhere due to some real technical failures like a broken compressor or a disjunction between the compressor and the functional unit.


  • Early detection is necessary.
  • Avoid using personal fillers to tackle the situation as this might worsen the health of the AC.
  • Consult a specialist as soon as possible to detect the problem and repair the AC.

3. AC is too noisy!

Many times people encounter strange, unwanted, and unwelcomed noises coming from their ACs. These noises should be taken under consideration with an alert behaviour as these are the indications that something is not right with the cooling unit.


  • The issue should not be overheard.
  • A fine checking of the whole apparatus including duct vents, fans, etc must be carried out.
  • Checking then must be followed by proper cleaning of the apparatus.

4. AC resists turning on

Sometimes it may happen that you come home to relax, try to turn the AC on but it resists turning on. A more conundrum situation arises when the AC turns on and off and on and loops again and again. This can be really a frustrating situation to happen. However, there can be multiple reasons for the issue but a tripping failure can be the leading one.


  • Check the connections.
  • Make sure the electrical breaker is working properly.
  • Turn the electric breaker switch on and off several times, if the condition doesn’t improve consult the specialist.

5. Dead batteries AC Problems

It may be possible at times when AC is not able to perform efficiently. This can happen when the thermostat is not getting the amount of energy it requires to maintain the proper functioning of the AC; this can result when the batteries are not working properly or when their circuits break. This is again one common problem faced many times.


  • Troubleshooting the battery should be carried out.
  • An Ac Repair in Indore technician must be consulted in case of circuit/thermostat failure.
  • Replace the batteries (however not frugal), if necessary.

6. Refrigerant leakage AC Problems

People are often found complaining regarding refrigerant leaks. Refrigerant leak in layman language can be understood as the ‘leakage of the cooling part’ of your AC. Now there are several reasons, due to which this problem can arise like an improper installation, wear and tear of the unit, internal failure, etc.


  • Make the installation firm and technically sound.
  • Keep a check on the unit for leakage.
  • Bring in note signs like AC taking too long to cool the area etc and take measures for it.

7. Defunct AC capacitor

AC capacitor is one of the most important components of an HVAC; a capacitor failure can take the device to a halt.  An AC capacitor is the core element that circulates the coil and helps in circulating the energy that is required for the AC to function. If the AC stops working or is showing irregular characteristics this could be the reason. A capacitor can fail to function because of many reasons like Overheating.


  • Restore the capacitor through repair
  • Replace the faulty capacitor
  • Consult a technician

8. Running Low on Refrigerant

If you’re not sure about what a refrigerant is, it plays a major role in the cooling process of the AC. So if there is low refrigerant then there might be a chance that your AC won’t work well. Plus, it isn’t as easy as changing the whole and requires a technician that would carefully look into the whole problem. Well, fixing this problem is sure to take up a lot of time. Plus, it’s going to land up really heavy on your pocket.

9. Evaporator Coils are Frozen

The main part in cooling the air is of the evaporator coil and refrigerant. The refrigerant fills up the evaporator coil absorbs the heat and makes the air cold. For that purpose, it needs warm air surrounding it most of the time. If the opposite happens the evaporator coils are bound to get frozen and then you might land up in getting warm air rather than the cold one. You will eventually find out about the fault as its symptoms are quite sure and your AC stops functioning in the case.

10. Dirty Condenser Coils AC Problems

With this much pollution and dirt in the air, this problem is bound to arise. The condenser unit does the final job in an AC and expels out the hot air. However, if the air is dirty and not impure, all of that gets collected in this unit. Thus, this causes your machine to work harder with every ounce of air it cools, increasing the workload on the machine. Pollution being one of the gifts of modernization, it is quite a problem in AC.

11. The fan isn’t working properly:

This might not seem a big problem but can end your AC in a really big mess if not treated properly. There are two fans in an AC, one that moves air to the evaporator coil and helps cool it and the other that moves air to the condenser unit and helps in expelling the hot air. Well, if even one of them falters it will lead to the failure of the compressor unit and eventually, your AC stops working completely. It can be due to a lot of problems, which include motor failures, excessive tear, or dirt. Whatever the reason it needs to be treated urgently.

12. Ductwork AC Problems 

Well, the most important thing for an AC is ductwork. After all, it is the one that circulates cool air without which all of the AC’s mechanism is nothing. The main reason behind the failed circulation of cool air can be leaking ducts. The ducts that carry cool might have some leakages which allow the cool air to escape out leaving no cool within the room. Not only this, but this will also increase pressure onto the whole driving out more power.

13. Programming AC Problems:

Sometimes the problem isn’t in the mechanism but the instruction. Technology is growing each day and with it grows complexity. The programmable ACs might be too difficult to understand and maybe the program it’s fixed upon doesn’t suit you at all and you might have made an error while programming it according to your taste. Whatever may be the reason the AC is bound to make an error in this scenario and you are bound to suffer. The solution to this problem is that you program it the day it’s installed by the technician himself.

14. Clogged Drains AC Problems:

What’s absorbed has to get expelled and this is what a drainage system does. It takes all the moisture and then excretes it out. But what if the drainage system is blocked, the water has to go somewhere. Two cases arise in the scenario: either it will go back and destroy the system or it leak and destroy your beautiful house. In both cases, your loss is bound unless you get it fixed.
