Air Conditioning Repair Certification (ETI) Practice Exam

The typical lifespan of a central air conditioning system is generally between 15 to 20 years. This range is influenced by various factors, including the quality of the unit, regular maintenance, and the operating environment. Units that are well-maintained tend to last longer, effectively utilizing components designed for longevity, such as high-quality compressors and coils.

Additionally, the environment in which the system operates can impact its durability. For instance, systems in regions with extreme temperatures may experience more wear and tear. Proper installation and following manufacturer guidelines also play crucial roles in maximizing the lifespan of an air conditioning system. Components like refrigerant lines and insulation need to be correctly configured to prevent inefficiencies or breakdowns.

It's essential for HVAC technicians and homeowners alike to be aware of these factors, as they contribute significantly to the overall performance and lifespan of the equipment. Thus, understanding that a central air conditioning system typically lasts 15 to 20 years can help in planning for eventual replacements and in making informed decisions regarding maintenance.
