What Is the Average Life of Split Air Conditioner?

Just like any other valuable home appliance, no one invests in a quality split air conditioner with the view of replacing it in a few years. The intention is to get as many years of service from the appliance as possible. 

Therefore it is normal to want to know the average lifespan of a split air conditioner before committing such a huge initial investment. This article aims to determine the average life of a split air conditioner and the main factors contributing to the AC’s lifespan. 

The Average Lifespan of a Split Air Conditioner

According to air conditioner repair services providers, an air conditioner’s standard expected lifespan is 15 to 20 years. However, this period can be longer or shorter depending on various influencing factors. 

This is also the average lifespan of most ACs in the market today. In retail, manufacturers attach the number of years the split appliance is expected to serve you on the purchase documents. However, these documents do not tell you that other factors will influence this lifespan. 

For example, a regularly maintained split air conditioner is more likely to add a few more years to its lifespan than a chronically neglected air conditioner. On the other hand, even a well-maintained air conditioner that is used in a hot environment is likely to age much faster than a semi-dormant air conditioner used just once in a while. 

Hence, here are the main factors that determine the actual lifespan of a split air conditioner;

The Level of Care

There is a standard amount of TLC that is required for all your home appliances. Your refrigerator, washing machine, coffee machine, etc. At the bare minimum, these appliances need regular cleaning and maintenance. This also applies to your Split AC.  

It is effortless to forget and ignore it. However, believe it or not, the level of attention and care accorded to the system directly affects its lifespan. To get the best out of your air conditioner, both short term and long term, ensure that the system is regularly cleaned and receives regular maintenance from a split AC expert.  

Regular maintenance and care ensure that the non-replaceable parts, e.g. condenser and blowers, are always in optimal condition—this way, they last longer than anticipated. 

Energy Usage

As energy is running through the appliance, the various internal parts work together in harmony to efficiently supply cool air into the room. This process makes the parts wear out, and over time, the depreciation becomes evident – this happens even with well-maintained split air conditioners. 

Therefore, it is natural that an appliance running around the clock will depreciate much faster than an appliance that runs only six hours each day. Manufacturers rarely consider the level of usage when estimating the average lifespan – they assume perfect conditions. 

Quality of Installation

DIY projects can be fun. However, if you are not an expert, leave the installation of the split air conditioner to the experts. This is because a single wrong move can significantly affect the whole system’s performance, or worse still, it might even lower the system’s life expectancy. 

If the installation was not optimal, the system might prematurely develop operational inefficiencies that will directly affect its lifespan. It is therefore essential to seek professional advice before installing your split air conditioner. 


Although the average expected life expectancy of a split air conditioner is approximately 15 to 20 years, the actual lifespan can be less or more depending on the above factors. 

It is helpful to give enough care and attention to your appliance if you want it to serve you for a more extended period.
