What Factors Affect the Cost of a New AC Unit?
Here are the main price drivers in Phoenix installs. If two quotes look far apart, it’s usually because one includes upgrades (duct sealing, electrical work, permits, or higher efficiency) while another is “equipment only.”
- System size (tons): Larger capacity systems typically cost more and may require ductwork updates.
- Efficiency (SEER2 rating): Higher-efficiency units cost more upfront but can lower energy use long-term.
- Ductwork condition: Leaks, undersized returns, damaged plenums, or poor airflow can raise installed cost.
- Electrical requirements: Panel capacity, disconnects, wiring, and code updates may be required.
- Installation difficulty: Rooftop access, tight attics, or crane work increase labor.
- Thermostat & controls: Smart thermostats or zoning add cost but can improve comfort.

FAQ: New AC Unit Cost
Does the price of a new AC unit include installation?
Most quotes include equipment, labor, refrigerant, startup testing, and standard parts coverage. Ask whether permits, ductwork repairs, electrical work, thermostats, or disposal fees are included.
What SEER2 rating is best for Phoenix?
Many Phoenix homeowners choose mid-to-high efficiency because cooling seasons are long. The best SEER2 depends on your budget, run-time, and how long you plan to stay in the home.
Is it cheaper to replace only the AC or the full HVAC system?
Replacing only the AC can be cheaper upfront, but mismatched components may reduce efficiency and lifespan. A matched system replacement often provides better comfort and warranty alignment.
