An air conditioner is a must-have in any home because it provides cool comfort during the hot summer months. Whether you're planning to replace a current system or looking to repair an existing one, it pays to know how long your air conditioner will last. We have researched this extensively, so you don't have to, and we'll walk you through the steps required to determine how long your AC will last. 

Air conditioners typically last between 15 to 20 years. Although this is a general estimate, some factors affect the lifespan of an air conditioner, including the amount of space, usage, maintenance, weather, etc.

An air conditioner is one of the biggest investments you make when improving your home, but it can be expensive to have one repaired. To help avoid this, continue reading this article and discover how you can prolong the life of your air conditioner.

Tips to Keep Your Air Conditioner Running in Good Condition for Long-Term

As an owner, you may have thought, how will air conditioners last for many years? As you continue to operate the unit, it could become inefficient and may even need to be replaced. However, if the air conditioning system is properly maintained, it can last for many years, possibly even 20 years, or more.

Air conditioners need regular maintenance, including cleaning, repairing, and replacing parts when needed. Cleaning will reduce the build-up of dust, dirt, and other particles. Clean filters are an important part of keeping the air conditioning system in tip-top shape.

Replacing filters can also improve the performance of the air conditioner. In addition, maintaining the proper amount of refrigerant will keep the unit running efficiently. 

There are times when the unit may need to be repaired. This includes fixing leaky or damaged parts, especially if the unit is already old. It is always a good idea to have the air conditioner checked by a qualified HVAC technician to evaluate if the AC can still be repaired, or will require a new one. 

It is also important to keep in mind that the repair could cost more than you would have expected.

How Long Does an Air Conditioner Last If Used Regularly?

Just like any electric home appliance, frequent usage can contribute to premature equipment failure, especially if routine maintenance gets neglected. 

It is really not a question of whether the air conditioner unit is used frequently or not, as long as you keep a watchful eye on your system's performance and ensure that the routine maintenance is adhered to.

Air Conditioning Units: Size Matters!

When buying an air conditioner, it is also important to keep in mind that your unit can last longer if you use the right size for your home. How powerful your unit will rely on the square footage of the room you are trying to cool.  

Central air conditioning units tend to be more energy-efficient if you want to cool your entire home, but they come with higher installation costs. Window units can be installed more quickly, but they may require more maintenance.

The amount of space where you want your air conditioner installed should always be taken into consideration. A large-capacity air conditioner fitted into a small room may cool it quickly, but this may result in the air conditioner cutting its cycle short, adding unwanted wear and tear that shortens its lifespan.

Does Choosing the Right Make and Model Affect the Lifespan of an Air Conditioner?

The model is the next vital factor to look at, as it will determine the unit's efficiency. Make sure that it meets the standard efficiency level set by the local government

Different models are designed for unique use. We also recommend hiring qualified people to install your air conditioner. Not only will you be sure that the unit will be placed properly, but you can also get some professional advise on how to maintain your AC to maximize its lifespan. You should also be aware of the manufacturer's warranty to take advantage of free parts replacement and labor.

Are New Conditioners Better Than Old Ones?

Planned obsolescence is a term used to describe the practice of creating a product that will become obsolete. It refers to the tendency of manufacturers to design products with an eye toward their eventual uselessness.

This is the practice of making sure you have the latest model because they're always improving on the old one. This concept in product development applies to air conditioning systems.

The main reason for the practice of planned obsolescence is to increase sales. A product that is being replaced every few years will continue to sell well. The newer version has a better design, is easier to use, and it's also easier to maintain.

By replacing the old model with a newer model, there will be fewer repairs to be made.

In addition, newer air conditioners are often more expensive than their predecessors. In addition to being expensive, they also offer a lot of extra features. Here are some examples of these additional features:

  • Programmable thermostats
  • Digital controls
  • Energy-saving technology
  • Self-diagnostics
  • Remote controls

Are Older Air Conditioners Good?

Despite the innovations in the HVAC systems, have you observed that the older generation of air conditioners are more durable than the new generation? They may not be rich in fancy features like the newer ones, but they are generally more reliable in terms of longevity.

However, longevity is just one aspect of what you need to look for in an air conditioner. There are other important factors to consider, such as efficiency and capacity. In addition, repairing older units can be a headache, especially when looking for replacement parts.

Since they are older units and newer units are being promoted, getting your hands on older parts will be more difficult than it was.

Older units tend to be less energy-efficient than newer ones, which does not make sense if you're trying to save money on monthly bills. Newer air conditioning units have upgraded parts that help them to perform at their peak performance. The trade-off is that these newer units are more expensive to buy.

In addition, older air conditioners are not environment-friendly. Their refrigerants emit more HFCs, or hydrofluorocarbons, that are known greenhouse gases. This means that these units are causing harm to the planet and contributing to global warming.

Why Are Modern Air Conditioners More Efficient?

Newer air conditioners are more efficient compared to older ones. This is because of the high rate of innovation and increased complexity of refrigeration systems. The previous lines were much simpler and were designed to work in a very narrow range of operating conditions.

Newer systems are more complex and can work in a broader range of conditions. These units also use smaller motors, which allow them to run at lower speeds, thus an energy saver. Air conditioning units have their own SEER ratings, which is the benchmark for measuring efficiency.

The wearing down of AC units is normal. As components age, performance dwindles, especially if there are broken parts and are not getting regular maintenance. Some components may start to fail from age, while others can be damaged through regular use.

It pays to get a trusted HVAC brand when choosing your AC. Do some research and look up reviews online regarding different brands. Joining HVAC forums is also one way of getting user reviews of particular brands. This way, you can get an honest evaluation from fellow users; that way, you know what you should avoid.
