- Schedule yearly servicing
- Dirty systems wear out faster
2. Usage Frequency
- Continuous usage in extreme heat reduces lifespan
- Moderate use helps extend durability
3. Installation Quality
- Poor installation = reduced efficiency
- Always hire certified technicians
4. Environment
- Dust, pollution, and humidity can damage components
- Outdoor units need extra care
