How much is a 3 ton AC unit installed in Florida? In the local market, a new 3-ton central AC with a matched air handler typically costs about $7,000–$11,000 installed (market estimate). Smaller 2-ton systems cost less, and 4–5 ton systems more. Size is set by a load calculation, not square footage alone. Pinellas Cooling & Heating gives free estimates in Pinellas Park.
If you're replacing an AC, the first question is usually "what will it cost for a house my size?" This page answers that with published local price ranges for each size, explains how size is really decided, and shows why two quotes for the same tonnage can look so different. These are market estimates, not our prices. Your exact number comes from a free, written estimate after we've seen the home.
| System size | Rough home size (guide only) | Installed cost (market estimate) |
|---|---|---|
| 2 ton | Up to about 1,200 sq ft | $6,000–$9,500 |
| 2.5 ton | Up to about 1,500 sq ft | $6,500–$10,000 |
| 3 ton | Up to about 1,800 sq ft | $7,000–$11,000 |
| 3.5 ton | Up to about 2,100 sq ft | $7,500–$12,000 |
| 4 ton | Up to about 2,400 sq ft | $8,000–$13,000 |
| 5 ton | Up to about 3,000 sq ft | $9,000–$14,500 |

These ranges assume your existing ducts can be reused. The low end of each row is typically a single-stage system at the Florida minimum efficiency; the high end is a two-stage or variable-speed system with more features. If you're asking how much it costs to replace a 2.5 ton AC unit, the 2.5-ton row is your answer: about $6,500–$10,000 in this market.
As a rough guide, many 1,500 sq ft local homes end up with about 2.5 tons and many 2,000 sq ft homes with about 3–3.5 tons. Treat that as a starting point, not an answer. The right size comes from a Manual J load calculation, the industry method that looks at:
A 1,500 sq ft block home with good attic insulation and shade might need less than the rule of thumb. The same size home with west-facing glass and a thin attic might need more. That's why we don't size from the old unit's label alone.
So what does that mean for budget? New AC unit cost for 1,500 sq ft typically lands in the 2.5-ton row above, and AC replacement cost for a 1,500 sq ft home is often similar unless the ducts or electrical need work. For a larger home, new HVAC system cost for 2,000 sq ft in Florida usually sits in the 3- to 3.5-ton rows.
Three tons is the most common size we see, and it's the most-asked price. In the local market, published prices for a 3-ton system include:
| 3-ton system type | Installed cost (market estimate) | Source |
|---|---|---|
| Central AC with matched air handler | $7,000–$11,000 | Pronto Service Pros, via Local HVAC Guide |
| Single-stage, 15.2 SEER2 | $7,500–$10,500 | I Care Air Care, via Local HVAC Guide |
| Two-stage | $9,000–$12,000 | I Care Air Care, via Local HVAC Guide |
3 ton AC unit cost in Florida: published local contractor prices. Estimates only.
Florida sits in the Department of Energy's Southeast region, where new split-system central ACs under 45,000 BTU (under about 3.75 tons) must be at least 15.2 SEER2, and larger ones at least 14.7 SEER2. So even a "basic" 3-ton system here is more efficient than the old units it replaces.

A complete installed price should include:
When you're comparing, check whether each quote includes all of these. A quote that's $800 lower but leaves out the permit and the pad isn't really lower.
Even with the same tonnage, prices vary because of:
Ask each contractor to list these on the quote. Then you're comparing systems, not guesses.
Yes. Duke Energy Florida pays $300 when you replace an existing AC with a new AC rated at least 15.2 SEER2. If you switch to a heat pump instead, the rebates are larger: $500, $600 or $1,000 depending on your current system and the new system's efficiency. Our guide to heat pump replacement cost in Pinellas Park explains those tiers.
To qualify, Duke requires a free Home Energy Check within the past 24 months (or within 12 months after an emergency replacement), a licensed and insured contractor, a permit, and the condenser and air handler replaced at the same time. As a Duke Energy verified contractor, we'll confirm the rebate your system qualifies for before you commit.
Don't assume bigger is better. In a humid climate like ours, an oversized AC cools the air fast and shuts off before it's had time to pull moisture out. The result is a house that feels cold and clammy, more on-off cycling, more wear, and sometimes mould-friendly humidity.
An undersized system has the opposite problem: it runs and runs on hot afternoons and may never reach the set temperature. The fix for both is the same: a load calculation. Sometimes it confirms the old size. Sometimes, after new windows or attic insulation, it shows you can go smaller and save money.

In the local market, about $7,000–$11,000 with a matched air handler, based on published contractor prices. A single-stage 15.2 SEER2 system sits toward the lower half; two-stage and variable-speed systems cost more. These are estimates, not quotes.
Often around 2.5 tons, but it depends on insulation, windows, sun exposure and construction. A Manual J load calculation gives the real answer, and we do one as part of every free replacement estimate.
No. An oversized AC short-cycles and leaves humidity behind, so the house feels damp even when it's cool. The right size runs long enough to dry the air as well as cool it.
The prices in our size table already include a matched air handler or coil: about $6,000–$9,500 for 2 tons up to about $9,000–$14,500 for 5 tons in the local market (estimates). Replacing both together is also a Duke rebate requirement.
