While systems nationally last 15-20 years, the extreme Phoenix heat reduces the average lifespan to 8-12 years due to the high operational load during summer months.
Local contractors use this rule: multiply the age of the unit by the repair cost. If the result exceeds $5,000, a full replacement is typically more cost-effective than a repair.
Permit fees in Phoenix are based on project valuation. For a standard $10,000 installation, expect to pay approximately $558 for a combined mechanical/electrical permit.
Homeowners can save up to 20% by scheduling replacements in the 'shoulder seasons' of March-April or October-November when demand is lower and contractors offer seasonal discounts.
