7 Ways to Increase the Lifespan of Your Air Conditioner

Air conditioning systems are essential for maintaining comfort in your home, especially during the scorching summer months. However, like any other appliance, your AC unit requires regular care and maintenance to ensure it operates efficiently and lasts as long as possible. 

Neglecting your air conditioner can lead to frequent breakdowns, reduced efficiency, and a shorter lifespan, ultimately costing you more in repairs and replacements. In this article, we explore practical tips and best practices to help you extend the life of your air conditioning system.

1. Regular AC Maintenance: The Key to Longevity

Regular maintenance is the best thing you can do to help increase the lifespan of your HVAC unit. You should have your unit checked and serviced at least once a year, ideally twice a year—once in the spring and once in the fall, before the drastic rise and fall of temperatures that cause your HVAC unit to work especially hard.

A regular HVAC tune-up will catch potential problems before they worsen, check for ways to increase the energy efficiency of your unit, and make sure there are no leaks or loose parts that are causing your unit to work harder than it needs to. A tune-up will also ensure that your ductwork is clean and unobstructed, allowing for optimal airflow. Don’t put a tune-up off for too long—regular tune-ups by a certified HVAC professional can add years of life to your air conditioning system. Scheduled maintenance helps identify and address potential issues before they escalate into major problems. It also ensures that your system operates at peak efficiency, reducing wear and tear.

Key Air Conditioning Maintenance Tasks:

• Change or Clean Filters: Dirty filters restrict airflow, making your AC work harder to cool your space. Replace or clean filters every 1-3 months, depending on usage and the type of filter.
• Inspect and Clean Coils: Over time, the evaporator and condenser coils accumulate dirt, reducing their ability to absorb and release heat. Clean the coils annually to maintain efficient cooling.
• Check the Thermostat: Ensure your thermostat is working correctly. Upgrading to a programmable thermostat will significantly help manage your system more efficiently by adjusting temperatures based on your schedule.
• Clear the Condensate Drain: A clogged condensate drain can cause water damage and affect humidity levels. Regularly check and clear the drain to prevent blockages.

2. Optimize Usage & Avoid Unessarily Overworking Your AC Unit

In a climate like the one we enjoy in Houston, it’s tempting to blast the AC 24/7 in order to keep your home cool and comfortable, especially in the summer. However, running any appliance at full blast without a break will wear it down very quickly. Appliances, much like people, need breaks in order to recuperate and perform at their best. In order to improve the longevity of your HVAC unit, consider some ways in which you can set limits on its use.

Even just increasing the temperature of the thermostat by one or two degrees can make a difference in the amount of effort your AC unit has to exert. When the home is unoccupied, make it a habit to increase the thermostat temperature by at least a few degrees. This will keep your home reasonably comfortable and regulated without needlessly overworking your air conditioner. When you’re out of town, consider setting your thermostat at around 78-80 degrees. Anything much higher will make your home uncomfortable to return to and can promote the growth of mold and mildew.

If it’s difficult for you to remember to reset your thermostat regularly, consider investing in a programmable smart thermostat that allows you to set a schedule that controls the temperature for you. There are also new thermostat models that allow you to control temperatures from an app on your mobile device while away from home.

How you use your air conditioning system significantly impacts its longevity. By optimizing usage, you can reduce the strain on your system, leading to a longer lifespan.

Tips to Optimize Usage:

• Set an Appropriate Temperature: Avoid setting the thermostat too low. A difference of just a few degrees can significantly reduce the load on your AC. A temperature of (72-75°F) is generally comfortable and efficient for homes with quality insulation and a properly performing HVAC system.
• Use Fans to Support Cooling: Ceiling fans or portable fans can help distribute cool air more evenly, reducing the need for your AC to work as hard.
• Close Blinds and Curtains: Prevent heat from entering your home by closing blinds or curtains during the hottest part of the day. This reduces the load on your air conditioner.
• Limit Heat-Generating Activities: Activities like cooking, using the oven, or running the dryer generate heat, forcing your AC to work harder. Try to perform these activities during cooler parts of the day.

3. Ensure Proper AC Unit Installation & Sizing

The installation and sizing of your air conditioning system play a critical role in its performance and longevity. An incorrectly sized unit can lead to frequent cycling, excessive wear, and higher energy consumption.

Consider the Following:

• Correct Sizing: Ensure your AC unit is appropriately sized for your home. A unit that is too large will cycle on and off frequently, while a unit that is too small will run continuously, both of which can reduce its lifespan.
• Professional Installation: Always hire a qualified HVAC technician to install your system. Poor installation can lead to leaks, inefficient operation, and increased wear and tear.

4. Keep the Outdoor Unit in Good Condition

The outdoor unit, or condenser, is a vital component of your air conditioning system. Keeping it in good condition is crucial for the overall performance and lifespan of your system.

Maintenance Tips for the Outdoor Unit:

• Keep It Clean: Regularly remove leaves, dirt, and debris from the area around the condenser. A clean unit operates more efficiently and experiences less wear.
• Ensure Proper Clearance: Make sure there’s at least two feet of clearance around the condenser. This allows for proper airflow and prevents overheating.
• Protect It from the Elements: Consider installing a protective cover over your outdoor unit during the off-season to shield it from snow, ice, and debris.

5. Address Air Conditioning Repairs Promptly

Even with regular maintenance, all air conditioning systems will experience issues from time to time. Addressing these problems promptly can prevent further damage and extend the life of your system.

Common AC Issues to Watch For:

• Unusual Noises: If your AC starts making strange noises, such as grinding, squealing, or banging, it could indicate a mechanical issue that needs immediate attention.
• Poor Cooling Performance: If your AC is struggling to cool your home, it may be due to a refrigerant leak, dirty coils, or a failing compressor. Don’t ignore these signs.
• Frequent Cycling: If your AC is turning on and off frequently, it could be due to an oversized unit, a faulty thermostat, or poor airflow. Have a professional diagnose the problem.

6. Consider Upgrading Older Systems

If your air conditioning system is more than 10-15 years old, it may be time to consider an upgrade. While this might seem counterintuitive when discussing extending the life of your AC, sometimes replacement is the best option for long-term efficiency and savings.

Benefits of Upgrading:

• Improved Energy Efficiency: Newer AC models are significantly more energy-efficient, which can reduce your utility bills and lower your carbon footprint.
• Enhanced Comfort: Modern systems offer better temperature control, quieter operation, and advanced features like humidity control and air purification.
• Reduced Repair Costs: Older systems are more prone to breakdowns, and the cost of frequent repairs can quickly add up. Investing in a new system can save you money in the long run.

7. Educate Yourself on AC Care

Being knowledgeable about your air conditioning system and how it works can help you make informed decisions about its care and maintenance. Understand the basic components and functions of your system, so you can recognize potential issues early and communicate effectively with HVAC professionals.

Resources to Consider:

• User Manual: Your AC’s user manual contains valuable information about maintenance schedules, troubleshooting tips, and operational guidelines.
• Online Guides and Tutorials: There are plenty of online resources, including videos and articles, that can help you learn more about your air conditioner.
• Consult a Professional: Don’t hesitate to ask your HVAC technician for advice or explanations during maintenance visits. They can offer personalized tips based on your specific system.

Increasing the life of your air conditioning system is not only about maintaining comfort but also about making a smart financial investment. Regular air conditioner maintenance, optimizing usage, ensuring proper installation, and addressing issues promptly are all essential steps in extending the life of your AC. 

By following these tips, you can keep your system running efficiently for many years, saving you money and preventing the inconvenience of unexpected breakdowns.
