The life expectancy of a new air conditioner in Texas typically ranges from 10 to 15 years. Factors affecting longevity include maintenance frequency, usage intensity, and environmental conditions. Regular upkeep, such as annual tune-ups and filter changes, can extend its lifespan. High temperatures and humidity in Texas can lead to increased wear and tear, potentially shortening the unit's life. Considering local climate and maintenance can help you manage and maximize the AC unit's performance and durability.
