Common questions
How much does a new HVAC system cost in Phoenix?
A full central AC and furnace replacement in Phoenix typically runs $6,900 to $19,600, with most homes near $13,200. Efficiency rating and home size set the price.
How long does an HVAC system last?
A well-maintained central system lasts about 15 to 20 years. Rising repair bills and uneven cooling are the usual signs it is time to replace.
Is a high-efficiency system worth it in Phoenix?
In AZ climates with long cooling or heating seasons, a higher SEER2 unit costs more up front but the monthly energy savings often pay it back over the unit life.
Do I need new ductwork with a new HVAC system?
Not always. If the existing ducts are sealed and sized right, they can stay. Leaky or undersized ducts add roughly $3,000 to do correctly.
