Due to extreme summer temperatures exceeding 110°F, systems in Phoenix typically last 10-15 years, which is shorter than the national average of 15-20 years.
It is a decision tool where you multiply the repair cost by the system's age. If the result exceeds $5,000 (e.g., a $600 repair on a 10-year-old unit), replacement is generally recommended.
The regional minimum for the Southwest is 14.3 SEER2, but most Phoenix homeowners opt for 16-18 SEER2 to manage high summer electricity bills.
Scheduling during the 'shoulder seasons' of March-April or October-November can save 10-15% compared to peak summer emergency replacements.
