6 Most Common AC Problems

While it is understandable that you want to enjoy using your Air Conditioning system for a long time, it is essential to know that it can develop problems. AC repair is usually very costly, given that the system is an expensive one. However, learning about the likely issues that your AC can develop will put you in a proper position and prevent you from falling victim to inexperienced technicians who may fix it wrongly and cause you to pay for another repair.

Also, you must employ the service of experienced HVAC maintenance and repair companies like Direct Air to ensure that your AC is properly checked and repaired whenever it develops any problem. With the help of qualified technicians like this, you can rest assured that your Air Conditioning system problem is fixed and you can even enjoy it better. You can learn more here.

Furthermore, learning about AC problems allows you to take appropriate preventative steps that further enhance the durability of your system. Also, certain issues are easy to fix at home, and learning about them will save you a lot of money where they repeatedly occur. Here are the 6 most common AC problems and simple home tips that can help keep your AC in good condition.

  1. AC is not turning on

The most common problem with Air Conditioner is when the unit is not just turning on. This occurs when the AC is hot, but you can’t feel any air circulating.

However, you do not need to contact a technician just yet; you can try some home tips and see if the AC will begin working. For instance, if you detect that your AC is not on, you need to check the thermostat batteries first and see if they are in good condition. If you notice that the batteries are dead, you will need to replace them.

If the batteries are in good condition, check the thermostat setting. In the setting, the AC needs to be in the cooling mode. If you find it off, on it and check if your unit is on. If this does not work, you may need to check the circuit breaker and see if it is off. Where it is off, flip the switch to put it on.

Where any of these tips does not seem to solve the problem, you need to contact an HVAC technician for check and repair.

  1. AC is not blowing cold air

Another common problem is when the AC is not blowing cold air. Note that many things can be responsible for this. A dirty filter is a significant reason your Air Conditioner may not be blowing cold air. Since this can terribly affect the house and cause you discomfort, it is ideal that you run a simple home check to see if this can be easily fixed.

For instance, you can check if the air filter is dirty. To do this, try hanging a white sheet at the front of the air vent. If the vent gets extremely dirty, you can assume that the air filter is dirty, and you can replace it. Also, you may want to remove the air filter to confirm if it is dirty or not.  Similarly, changing your air filter periodically can help you prevent this problem from happening at all.

  1. AC is making endless noises

If you realize that your Air Conditioner starts making endless noise, there may already be a problem with the unit. While it is hard to make an accurate guess as to what may be wrong with the AC. You can assume certain things depending on the noise you are getting from the unit.

For instance, if your AC makes a hissing sound, you may be dealing with a refrigerant leak.  A constant clicking sound may indicate that your AC just developed a relay problem, and when your AC starts to make screeching noise, the motor fan or compressor may be faulty. I do not recommend making guesses, and you should not ignore unusual noise. Contact your HVAC technician to help check the unit immediately if you notice this sound.

  1. AC’s evaporator coil is frozen

Just like the AC distributes air into the house, it also needs air for proper operation. Insufficient air can cause the evaporator coil to freeze, and this can cause the AC to stop working. The causes of inadequate air are not farfetched, and it may be dirty filters, ducts, blocked vents.

Try replacing the air filter and cleaning the vent thoroughly to attend to this problem. A good HVAC technician can also help you prevent this with periodic maintenance.

  1. Control failure

It is also possible for the electric control of your AC to stop working. This means the on and off switch is failing or no longer working, and it can be because the fan motor and compressor have worn out due to constant usage.

If this is the problem, you may want to check your connection first to ensure it is not an electric failure. If you cannot do it, contact a technician to properly look at things and fix them up.

  1. Water dripping

While water dripping from the AC is a regular thing and should not be a problem, you should consider confirming this directly from a technician to avoid any problem. This is because other things like a blocked drain pipe, improper installation, and broken condensate pan can cause water dripping and need to be fixed.


While repairing your AC can cost a lot of money, some of the repairs can be done at a relatively low price. In addition, timely service can allow your technician to detect the problem on time and prevent it from turning into a significant problem. This is why it is recommended that you pay for period AC maintenance and also take proper care of the system.
