Average Lifespan of an AC Unit in Arizona

Unfortunately, air conditioners don't last as long in Arizona as they would if they were installed in a cooler climate. On average, they tend to last between 10 and 14 years. The intense heat in Arizona often requires systems to work harder and wear out sooner.

Older models may not last as long because they tend to have a less efficient design. If they're well maintained, newer models may last closer to 15 years. If you're not sure how to tell how old your AC unit is, check the condenser nameplate. It should include the manufacturing date (MFR DATE) to tell you its age.

Factors That Affect AC Longevity

Several factors impact your AC's general lifespan and how well it can keep up with the Arizona heat, including:

• Usage intensity. The more you use an AC, the sooner it will wear out.
• Maintenance habits. Regular filter changes, coil cleaning, and tune-ups go a long way in protecting the system. However, if you skip maintenance, it's likely you'll see issues that require a replacement sooner.
• Installation quality. Poorly installed systems rarely work as efficiently as they should. This can put additional strain on the AC, leading to premature failure.
• Size of the unit. Bigger isn't always better with ACs. If you have a system that isn't sized correctly for your home, it will struggle to cool efficiently. Over time, it could face significantly more strain than if you had installed the correct size.
• Refrigerant type. Some units use R-22 refrigerant, which is now outdated as of 2020. If the refrigerant can't be sourced, you may need to replace your system sooner. Check your manufacturer’s label to see the refrigerant type.

When to Repair vs. Replace Your AC

Deciding when to repair vs. replace an AC can be difficult. While an HVAC professional can assess your AC and recommend the best choice, we have some general rules of thumb that can help you decide.

Repairs make sense on systems that are less than 10 years old and have had no major issues in the past, or if the parts are under warranty. They also make more sense when the repair cost is less than 30% of the price of investing in a new system.

However, replacement is the better option if your system is 10 to 15 years old and struggles to cool efficiently. You may notice that repairs are becoming more frequent or that your energy bills increase. We may also recommend you replace your system if it still uses outdated R-22 refrigerant.

Tips for Maximizing AC Lifespan in Arizona

Learning how to extend the life of your AC in Arizona can go a long way in improving longevity. Consider these tips:

• Schedule annual maintenance to prevent major issues. With MintCare, you get two comprehensive system checks and filter replacements each year and discounted service calls to ensure comfort all year long.
• Change air filters regularly to reduce overall system strain.
• Use a smart thermostat to minimize strain on the system by only cooling your home when you need it.
• Make sure you have your house inspected for air leaks and invest in good insulation to reduce the workload your AC has to keep up with.
• Install your AC somewhere shaded and free from debris to prevent airflow blockages and overheating.

Key Takeaways on AC Longevity and Maintenance

Arizona's climate isn't kind to ACs, but regular maintenance can help you maximize their performance for 10 to 15 years. Considering age, efficiency, and overall repair costs can also help you choose the right way to move forward.
