How long do AC Units last?

29. November 2021 | Air Conditioner

Just like any other electronics, air conditioners break down too. It is too bad that they don’t last as long as you do. No matter how often you maintain it, there will come a time when it will stop working. 

Many of you wonder how long do AC units last? Typically, an air conditioner can last up to 20 to 25 years, provided you maintain it well. But the number of years may reduce due to various factors. One of the main causes is a lack of maintenance.

HVAC maintenance is one of the most crucial things. It not only enables the system to function correctly but also extends its life. But unfortunately, many users ignore the importance of regular maintenance. This leads to issues in the unit, which can eventually damage it. When that happens, you either have to get a new AC or repair the old one, if it is possible.

If you don’t want your HVAC system to suffer and get damaged before time, you should maintain it properly. In this post, we will discuss how to extend the life expectancy of your AC unit.

Factors That Affect The Life Of An Air Conditioner

Factors for longer life

Lack of maintenance is not the only cause that reduces the life expectancy of an AC. There are other contributing factors too, which we will be discussing in this section. Knowing them beforehand can help you keep your unit in good condition.

  • Lack of maintenance

As already mentioned above, maintaining your HVAC system is extremely important. While some of the maintenance can be done at home, you may have to call a technician for some of the other parts. By maintaining your unit, you cannot only improve its functioning but also make it last longer.

When it comes to maintaining an AC, many people ignore the outdoor unit. This again could cause a lot of problems. From cleaning debris around the unit to checking the refrigerant lines, you have to do it all to keep your AC in good condition. Regular maintenance can save you from unwanted repairing costs.

  • Air filter 

Another big factor is the air filter. Many of you may know the air filters of an AC needs to be changed or cleaned from time to time because they get dirty. Cleaning or changing the filter is another effective way to extend the life of your unit.

A dirty air filter puts a lot of pressure strain on the unit. This can cause the unit to shut down, and that is why it is recommended to change the air filter every 90 days. If your unit comes with reusable air filters, you should clean it every month. Sometimes depending on your location and season, you may need to change the filter twice a month. This is true for places where there is excessive dust or pollen in the air.

  • Constant usage

We all use an AC almost every day in our lives and that for hours. The more you use your AC, the more wear and tear it gets. In other words, it affects the life span of the unit. If you are using your unit regularly with very few breaks, it is likely to get damaged faster. However, you can keep the system running efficiently with frequent cleanings, programmable thermostats, filter changes, and regular maintenance.

You cannot make your unit last for a lifetime. But at least you can extend a few years by maintaining and using it properly. You should give regular breaks to your AC so that the internal parts are not strained from excessive usage or overheating.

  • Installation issues

Yes, even proper installation of your HVAC system matters. That’s because it has a lot to do with the life span of your AC. You should always hire a qualified professional to install your unit. The technician should have adequate knowledge of installing AC units.

Ensure that the unit is installed correctly, ductwork is properly placed, everything is sealed, and the venting is situated effectively. All this can make a world of difference for your AC.

If you wonder how to make your AC unit last longer, we have just the right tips for you. By following these guidelines, you can easily make your system last up to 20 years or more.

  • Give your AC rest 

When you use your AC constantly, it wears out quicker. This is why it is crucial to turn it off in regular intervals. This will give your unit the time to cool down. Alternatively, you can turn the thermostat at a minimum of 5 degrees. This will let the unit stay on but not cool the air. You can also increase the thermostat at night, which helps you prolong the life of your unit.

  • Maintain your AC regularly

Maintaining your AC unit regularly can let you know its issues so that you can fix them on time. With regular maintenance and cleaning, you can extend the life of your HVAC system.

You should also pay attention to the outdoor AC unit as it accumulates dirt and debris over time. Cleaning the dust or debris will keep your AC unit working optimally. When you clean the outdoor unit, the chances of a mechanical breakdown become less.

  • Clean the ducts 

When the air ducts get dirty, it slows down the airflow into your room. In that case, you need to clean the ducts to maintain the airflow. Air ducts should be cleaned once a year. For this, you need to call a technician. 

  • Change the Filter

You also need to change the air filters of your unit to allow it to function correctly. If you are using reusable filters, you need to clean them regularly with soap water. But it is recommended to change the filters if they are too old.

How long do AC Units last – Summary

An air conditioner can last up to 20 to 25 years with proper maintenance. From regular cleaning to changing filters to servicing, you need to do all of it to keep the unit running. Ignoring the importance of maintenance can reduce the life span of your unit. You should also give your air conditioning some rest when it is in operation every day.
