AC Replacement Cost Calculator (North Texas, 2026)
A new central AC system costs $7,000–$16,000 installed for most North Texas homes in 2026 — most homeowners pay $9,000–$13,000 for a mid-tier 3–4 ton system on existing ductwork. Estimate your home below. No email, no sales call.
This is a researched estimate for the Dallas–Fort Worth market, not a quote. Your real price depends on your home's layout, electrical, refrigerant lines and permit fees. For an exact, itemized number see our AC replacement cost guide.
What's included in a North Texas AC replacement
The ranges above assume a complete, permitted system changeout: a new outdoor condenser, a matching indoor coil or air handler, refrigerant, a basic thermostat, labor, haul-away of the old equipment, startup, and the city mechanical permit. They do not assume major duct replacement, electrical upgrades, or zoning — those add cost, which is why the calculator lets you flag ductwork.
What moves your price the most
- System size (tonnage). Bigger homes need more capacity; price scales roughly with tons.
- Efficiency tier (SEER2). A high-efficiency variable-speed system can cost $4,000–$6,000 more than a standard single-stage unit of the same size.
- Ductwork. Replacing aged or undersized ducts adds roughly $3,000–$6,000.
- Electrical & line set. Panel capacity, a new disconnect, or a long refrigerant line run can add several hundred to a couple thousand dollars.
- Refrigerant transition. 2026 systems use R-454B, which raised equipment costs across every brand.
Frequently asked questions
How much does it cost to replace an AC in North Texas in 2026?
Most full replacements land between $7,000 and $16,000 installed, with $9,000–$13,000 being typical for a mid-tier 3–4 ton system on existing ductwork. High-efficiency variable-speed systems or full duct replacement can push totals past $18,000.
What size AC do I need for my home?
A rough rule for North Texas is about one ton of cooling per 500–700 square feet, but the right size depends on insulation, windows, ceiling height and sun exposure. A contractor should run a Manual J load calculation rather than just matching your old unit.
Why is this more expensive than a few years ago?
The federal refrigerant phase-out (R-410A to R-454B) added several hundred to over a thousand dollars per system, and higher SEER2 efficiency minimums plus DFW labor demand pushed installed prices up roughly 15–25% above the national average.
