How Long Do Portable Air Conditioners Last?

Portable air conditioners are one of the best solutions to combat heat in summer. They have become a perfect match to beat this heat during summertime as they are very easy to install and move from one room to another.

In this article, you find information regarding the lifespan of an air conditioner and how it is impacted by some external factors.

Portable air conditioners have different lifespans depending on their quality and features.

Usually, as per the energy department, an average air conditioner of good quality has a lifespan of 5-10 years. But some factors have a direct impact on the lifespan of air conditioners.

Factors Affecting the Lifespan of a Portable Air Conditioner

1. Usage:

Wear and tear play an important part in the lifespan of an air conditioner. The components of an air conditioner are built to endure wear and tear up to a certain level. Usage can influence the lifespan of air conditioners in many ways such as:

  • Frequency: Air conditioner will face more wear and tear if it is being used more frequently. Constant use without any break will affect its long-term usage.


  • Duration: Longer duration of usage of air conditioner can damage its parts and it can experience more wear and tear.


  • Humidity and Temperature: If an air conditioner works in extreme temperatures and high levels of humidity, it can face wear and tear which shortens its lifespan.

2. Maintenance: 

Maintenance plays a crucial role in the lifespan of an air conditioner. Maintaining an air conditioner ensures good-quality cooling. Maintenance requires some basic steps which are as follows:

  • Cleaning: All parts of air conditioners require to be cleaned in a specific way after some time. For instance, the filters need to be cleaned with a warm wet piece of cloth.

Water should be drained after 8-10 hours from the water tank which will prevent mold and microorganisms to grow in the air conditioner.

  • Levels of Refrigerant: HVAC technicians can check the refrigerant level and it can be maintained. A low level of refrigerant can put strains on a compressor.


  • Lubricants: Some parts of the air conditioner require lubricants such as the fan and motor. Lubrication helps these parts to play their role effectively and faster.

3. Quality:

The quality of an air conditioner works directly proportional to the working of air conditioners. If the air conditioner is of high quality, it has a long lifespan.

If you purchase an air conditioner of low quality, it negatively affects the capacity of its cooling power and the functioning of other parts.
