Tips for Extending the Lifespan of Your AC Unit

You have the power to extend the lifespan of your air conditioner with the right care. By employing a blend of maintenance techniques and preventing excessive strain on the system, you can significantly prolong its functionality. In this article, we will discuss ten best tips to help you extend the lifespan of your AC unit.

Is it Possible to Extend the AC Unit Lifespan?

Yes, we can extend the lifespan of our AC unit through proper maintenance and care. According to the U.S. Department of Energy, regular maintenance such as cleaning or replacing filters, cleaning the coils, regular AC repair & maintenance, and checking the refrigerant levels can help improve the efficiency and extend the lifespan of your air conditioner.

Ten Best Tips to Extend the Lifespan of Your AC Unit

Tips to Extend the Lifespan of Your AC Unit

Following are the key tips which are necessary to extend the lifespan of your AC unit.

1. Regular Maintenance

Your AC requires routine maintenance to perform efficiently. Schedule an annual or bi-annual checkup with a pro to keep it running smoothly. A qualified AC technician will:

  • Perform a thorough inspection of the entire AC unit.
  • Address any necessary repairs (if required).
  • Clean and lubricate all moving parts.
  • Inspect and clean the ductwork.
  • Replacement of air filters (if required).
  • Top up refrigerant levels if they are low.

2. Keep the Outdoor Unit Clean

The outdoor condenser unit is exposed to the elements, making it susceptible to dirt, debris, and vegetation buildup. Ensure that debris, vegetation, and other objects around the unit are at least 2-3 feet away.

Regularly inspect and clean the unit, removing any leaves, grass clippings, or debris that may accumulate around it. This will ensure that the unit will get the proper air flow it needs to operate effectively.

3. Clean the Condenser Coils

Transformation of heat from the air to the outside environment depends upon the condenser coils. These coils must be periodically cleaned to ensure that they continue playing their essential part in the cooling process. When they accumulate dust and grime, the efficiency of the compressor will go down and may even cause you to consider repairing the air conditioner.

4. Change Air Filters

Clogged air filters restrict airflow, causing your AC unit to work harder and consume more energy. Replace disposable air filters every one to three months, depending on usage. For reusable filters, clean them according to the manufacturer's instructions. This simple task can significantly improve efficiency and prolong the lifespan of your unit.

5. Install a Programmable Thermostat

A programmable thermostat allows you to set and schedule the temperature according to your preferences and daily routine. If you’re away from home, consider using a programmable or smart thermostat to adjust the temperature automatically.

Set your thermostat at an energy-efficient temperature and avoid drastic temperature fluctuations. By reducing the workload on your AC unit during times when cooling isn't necessary, you can prolong its lifespan and save on energy costs.

6. Use Ceiling Fans

Using ceiling fans will help your air conditioning unit to circulate the air throughout the home, allowing it to cool down faster. As a result, the AC will not have to work as hard to create the needed temperatures inside. This decreased workload will extend the unit’s lifespan and reduce the need for repairing the AC as often.

7. Provide Shade for Outdoor Unit

Direct sunlight can cause your outdoor unit to overheat, reducing its efficiency and lifespan. Install a shade structure or plant trees and shrubs around the unit to provide natural shade. However, ensure vegetation is at least two feet away to prevent airflow obstruction and debris buildup.

8. Avoid Overworking Your AC

Don't overwork your AC – give it a break when you can. Open windows on cooler days, use ceiling fans to circulate air, and bump up the thermostat a degree or two. Your AC will thank you by sticking around a little longer.

9. Monitor Refrigerant Levels

Low refrigerant levels can spell trouble for your AC unit. Keep an eye out for any signs of leaks or hissing noises, and contact a professional technician to inspect and repair any leaks. Catching issues early means less damage and more years of cool comfort.

10. Know When to Say Goodbye

Despite your best efforts, there may come a time when repairing your AC unit is no longer cost-effective, and replacement is the most viable option. If your unit is over ten years old, requires frequent repairs, or experiences a significant drop in efficiency, it may be time to consider upgrading to a newer, more energy-efficient model.
