When purchasing a new air conditioner, prioritize reputable brands known for durability. While the initial investment might be higher, the long-term savings and extended lifespan make it a wise financial decision.

4. Climate-Adapted Operation

Adjust your thermostat settings based on the prevailing climate. During milder weather, consider utilizing fans or opening windows to alleviate the workload on your air conditioner.

5. Timely Repairs

Address any issues promptly. Ignoring minor malfunctions can lead to more significant problems, shortening the overall lifespan of your air conditioner.
