HVAC Replacement Cost in Phoenix, AZ: 2026 Price Guide
A full HVAC replacement in the Phoenix metro typically costs $4,800 to $14,000, depending on whether you install a split system, a rooftop package unit, or a heat pump, and how much ductwork needs to be modified. Because Phoenix runs its cooling systems nearly year-round, choosing the right equipment type and confirming SEER2 compliance up front matters more here than in milder climates, and this guide breaks down what drives the price.

Split system vs. rooftop package unit pricing
A straightforward split-system replacement, keeping the existing ductwork and matching the new condenser to an existing air handler, typically costs $4,800 to $8,500 in Phoenix. A fuller split-system replacement that includes SEER2-compliant equipment and some ductwork work runs $6,500 to $12,500.
Rooftop package units, still common in older neighborhoods like Encanto and North Central Phoenix, are generally more expensive to replace, typically $7,000 to $13,000, largely due to crane or roof-access labor and the need to match roof curb dimensions on the new unit.
Heat pumps vs. traditional AC and gas furnace setups
Given Phoenix's mild winters, heat pumps are an increasingly practical option since they handle both heating and cooling efficiently without the cost of running a separate gas furnace. A heat pump conversion or new install typically runs $7,500 to $14,000 depending on system size and any electrical panel upgrades needed.
Homeowners who rarely use their gas furnace beyond a handful of cool desert nights each winter often find a heat pump pays off through summer cooling efficiency gains, though the right choice depends on your home's electrical capacity and current ductwork condition.
SEER2 requirements and what they mean for your quote
All new residential air conditioning and heat pump equipment sold in the U.S. must meet current SEER2 minimum efficiency ratings, which affects both equipment selection and price compared to older SEER-rated systems. Any Phoenix contractor's replacement bid should list the SEER2 rating clearly.
Higher-SEER2 equipment costs more up front but can meaningfully reduce summer cooling bills given how many months of the year Phoenix systems run continuously. Ask your contractor to model expected energy savings against the higher purchase price before deciding between a baseline and a high-efficiency unit.
Permits, rebates, and final steps
Any full HVAC replacement in Phoenix requires a mechanical permit from the City of Phoenix Planning and Development Department, generally filed through the SHAPE PHX portal, along with a final inspection. Confirm with your contractor, in writing, who is responsible for pulling this permit.
Check whether a utility rebate applies to your installation: SRP currently offers up to $1,125 back through its Cool Cash program for qualifying high-efficiency AC installs, while APS discontinued residential equipment rebates as of January 1, 2026. Always confirm your contractor's Arizona ROC license at roc.az.gov before signing a replacement contract.
