Why does an Air Conditioner become inefficient? 

It’s no wonder that air conditioners can become inefficient over time. After all, any machine that is used regularly will eventually show signs of wear and tear.

But why exactly does an air conditioner become inefficient? Here, we’ll take a look at the most common reasons why an air conditioner can become inefficient over time and a further look at how to prevent this from happening.

#1 The build-up of dirt and dust

One of the main reasons an air conditioner can become inefficient is due to a build-up of dirt and dust in the unit. Over time, this can build up and block important components such as the condenser, evaporator and cooling coils.

This means that the system will not be able to cool the air properly, resulting in less efficient performance.

#2 Refrigerant leaks

When refrigerant leaks from your air conditioner, it can cause inefficiency. Refrigerant is what helps keep your air conditioner cool, so when it’s low, the cooling process won’t be as effective.

To identify a refrigerant leak, you may notice these:

  • Warm air coming from the vents: If you notice that the air coming from the vents is not as cold as it should be, it could be a sign of a refrigerant leak. This can be caused by a hole or crack in the refrigerant line, which allows the coolant to escape and reduces its effectiveness.
  • Frost or ice build-up on the refrigerant lines: If you see frost or ice build-up on the refrigerant lines, it could be a sign that the refrigerant is leaking. This can occur if the refrigerant pressure is too low, which can cause the refrigerant to escape through the lines and create frost or ice as it comes into contact with the air.
  • Increased energy bills: A refrigerant leak can cause your air conditioning system to work harder and use more energy to try and maintain the desired temperature. This can lead to an increase in your energy bills.
  • Strange noises: If you hear hissing, bubbling, or gurgling noises coming from your air conditioning unit, it could be a sign of a refrigerant leak. These noises may be caused by the refrigerant escaping through a hole or crack in the lines.
  • A pungent smell: Refrigerant has a distinct, pungent smell that can be detected if it is leaking. If you notice a strong, chemical smell coming from your air conditioning unit, it could be a sign of a refrigerant leak.

And it is best to have this problem diagnosed and addressed by a professional air conditioning repair technician. If not, you risk further damage to the unit and loss of efficiency.

#3 The deterioration of air filters

One of the primary reasons an air conditioner becomes inefficient over time is due to a worn-out air filter.

The air filter must be changed regularly to keep your air conditioner running at its peak efficiency. Over time, the air filter can become clogged with dust and dirt particles, which will reduce airflow and reduce the efficiency of your unit.

Additionally, it may damage other components of the unit due to increased stress on the system. As a result, you should check and replace your air filter regularly to maintain optimum efficiency.

#4 The dirty fans inside the air conditioner unit

The fans inside an air conditioner unit help to circulate the cool air around the area being cooled. Over time, these fans can become dirty or clogged, reducing airflow and efficiency.

This can be caused by a build-up of dust and dirt, or blocked grills and vents. Additionally, the fan motor itself may wear out, resulting in decreased performance.

#5 Worn out components

One of the biggest causes of air conditioner inefficiency is worn components. As the unit ages, the parts within it may begin to wear out, causing a drop in efficiency.

The compressor is one of the most important components of an air conditioner, and when it starts to break down, the system can become much less efficient. The condenser fan motor is also important, as it helps circulate air around the unit.

Other components such as the evaporator coil and expansion valve can also become damaged or worn out over time.

#6 Incorrect size

Air conditioners need to be the right size to function properly. If they are too small, they will not be able to adequately cool the space, causing an inefficient unit to work harder and consume more energy to provide adequate cooling.

On the other hand, if they are too large, they will not be able to cycle long enough to remove enough moisture from the air. This can cause your air conditioner to freeze or blow hot air, both of which reduce its efficiency. 

Be sure to properly size your air conditioner for your home before installation so it will run efficiently for years to come.

#7 Using the air conditioner in extremely hot or humid conditions

Using the air conditioner in very hot or humid conditions can put too much strain on the unit. This is because the air conditioner will work harder to cool the air and keep your home comfortable. 

The unit may be less efficient, as it has to work harder than normal to cool the air. Also, the unit may be more prone to breakdown due to the stress of working in such extreme conditions.

#8 Age of the unit

The age of your air conditioner can also contribute to its inefficiency. As your air conditioner gets older, it may begin to lose its effectiveness due to normal wear and tear. 

Over time, components inside the unit begin to break down, reducing cooling performance. This can be especially common if your air conditioner is more than 7 years old.
