AC replacement cost by system size
The figures below are budgeting examples, not a sizing recommendation. Square footage alone cannot determine the right capacity: insulation, windows, air leakage, ceiling height, and ductwork also matter. Confirm the equipment size with an in-home load calculation.
| Home Size | Example System Capacity | Estimated Cost (Installed) |
|---|---|---|
| Under 1,000 sq ft | 1.5 – 2 ton | $8,500 – $10,000 |
| 1,000 – 1,500 sq ft | 2 – 2.5 ton | $9,000 – $11,000 |
| 1,500 – 2,000 sq ft | 3 ton | $10,000 – $12,500 |
| 2,000 – 2,500 sq ft | 3.5 – 4 ton | $11,500 – $14,000 |
| 2,500+ sq ft | 4 – 5 ton | $13,000 – $15,000+ |
⚠️ These are ballpark estimates only. Every home is different — actual pricing depends on your specific equipment, existing ductwork, electrical setup, and accessibility. The only way to get an accurate number is a free on-site inspection by one of our technicians. Call us and we’ll come take a look, no obligation.
What Affects the Price?
1. SEER2 Rating (Efficiency)
SEER2 measures seasonal cooling efficiency using a different test procedure from SEER. For standard split-system central AC installed in Louisiana since January 1, 2023, the Southeast minimum is 14.3 SEER2 below 45,000 Btu/h and 13.8 SEER2 at or above that capacity. Other equipment classes have different requirements. Compare quoted systems using their certified SEER2 ratings. Potential energy savings depend on your existing equipment, installation, usage and electricity rate.
2. Brand
Tegridy Air installs Rheem and Ruud equipment — two of the most trusted names in the HVAC industry. Both brands are known for their reliability, strong warranties, and performance in demanding climates like South Louisiana. Whether you’re looking for a solid mid-range system or a high-efficiency unit, we’ll help you find the right fit for your home and budget.
3. Labor & Installation Complexity
A straightforward swap-out on an accessible unit takes 4–6 hours. But if your installation requires electrical panel upgrades, new refrigerant line sets, or attic/crawlspace access, that adds time and cost. We always give you a full quote before touching anything.
4. Ductwork Condition
If your ducts are leaky or undersized, a new AC won’t perform the way it should. Sometimes duct repairs or partial replacement are recommended alongside a new unit. We’ll always tell you upfront if this is the case — not after the fact.
Signs It’s Time to Replace (Not Repair)
Not sure whether to repair or replace? Compare the written repair cost and replacement quote, then consider the system’s age, condition and repair history. The prices here are planning figures; an in-home assessment establishes the scope and price. Reasons to discuss replacement include:
- You’re calling for repairs every summer
- Your energy bills have been climbing year over year
- The system uses R-22 refrigerant (no longer manufactured)
- It’s not keeping your home comfortable even when running constantly
HVAC Financing Through Synchrony and FTL Finance
Financing through Synchrony and FTL Finance can help you plan payments for an HVAC replacement. Call (504) 414-8655 to discuss current financing options and the application process. Eligibility, repayment terms and available offers depend on the financing program.
What to compare in written AC replacement quotes
- The exact outdoor and indoor equipment models and their matched efficiency rating.
- Whether the price includes duct repairs, line-set work, electrical changes, controls, and removal of old equipment.
- The proposed system capacity and how it was sized for your home.
- Equipment and labor warranty coverage, registration requirements, and exclusions.
- The total installed price and any optional work listed separately.
If you are weighing a repair first, our Kenner AC repair service can help establish what failed and the proposed repair cost. You can also review our Kenner HVAC services.
