How to Make Your Air Conditioner Last Longer

All it takes is one look at the price of a new AC system for most homeowners to immediately ask what they can do to make their ACs last longer. While investing in a new system, it’s important to invest in your current AC throughout its lifetime to ensure that it lasts as long as possible. Here are a few, small best practices that will make your air conditioner last longer – if done consistently. 

Replace Your Air Filters 

One of the easiest — and most neglected — AC system chores is replacing your air filter when it gets dirty. A dirty filter leads to low airflow as well as dust and debris in the system, which can cause serious problems. As easy as it is to forget to replace your filter, it’s an important part of maintaining your air conditioner. 

While the replacement schedule will vary depending on the type of HVAC filter you use, standard filters need to be changed out every one to three months. You can set a reminder on your phone or write a note in your calendar to help you stay on top of it. 

Open All Vents 

Airflow is an important part of keeping your AC running smoothly for longer. While it may seem smart to close your vents and redirect the cool air to rooms you use more often, this does more harm than good. Rather than redirect cool air, closing the vents simply blocks it from exiting the system, making your air conditioning unit work hard to cool the house. Open all of your AC vents to maximize both airflow and energy efficiency. 

Schedule Regular AC Maintenance 

The best way to extend the life of your AC is to schedule seasonal AC tune-ups. These should be done each spring before the system is put under too much strain from the heat of summer and winter. Having a professional inspect and tune up your AC each comes with several benefits, including:

  • Improving the system’s energy efficiency 
  • Catching repairs before they cause more problems 
  • Significantly reducing the risk of breakdowns 

All of these benefits lead to a longer, healthier lifespan for your air conditioner. While it may not seem like a big deal, keeping to a regular maintenance schedule each year could be the difference between replacing your AC after 10 years and replacing it after 15 years or more. 

Keep a Consistent Temperature 

While thermostat wars are a common problem in many households, changing the temperature frequently can put a lot of undue stress on the AC unit as it tries to keep up with all of the different demands. The best way to avoid straining your system is to set a consistent temperature. One way to do this is by getting a programmable or smart thermostat. This way, you can set the schedule and leave it alone, or “set it and forget it.”  


It doesn’t take much effort or time to follow these simple steps, but they can make a big difference in your AC’s lifespan. Southern Air is committed to helping you maintain your AC, from offering advice on your system to performing AC tune-ups.
