It is the first question every Florida homeowner asks, and the one the internet answers worst. Search results throw out wide national ranges that mix a small condo in a mild climate with a large Wellington home that cools nine months a year — and none of them have seen your house, your ducts, or your panel.
So this guide does something more useful than invent a number: it walks through every factor that actually moves a replacement price in Florida, explains why two quotes for the same home can differ by thousands, and shows you what a proper, itemized quote should contain. When we quote a replacement, the price is in writing before work begins — this page explains what is inside that price.
Why There Is No Honest Single Number
A replacement is not a product you buy off a shelf; it is equipment plus the labor and supporting work to fit it correctly to one specific house. Two homes on the same street can legitimately price very differently because their ductwork, electrical capacity, equipment size, and installation access differ.
Any contractor who gives a firm replacement price over the phone, sight unseen, is guessing — and the guess usually grows after the old system is already out. A real price requires a load calculation, a duct inspection, and a look at the electrical side. That is why we diagnose and measure before we quote, on this work most of all.
Factor 1: System Size and the Load Calculation
Equipment is priced partly by capacity, and capacity should come from a room-by-room load calculation — ceiling height, window area and direction, insulation, and South Florida design temperatures — not from matching whatever tonnage happens to be outside today.
The wrong size costs you twice. Oversized equipment costs more up front, short-cycles, and leaves humidity behind. Undersized equipment runs constantly and never catches up in August. If a quote never mentions how the size was chosen, that is a question worth asking.
Factor 2: Efficiency and Equipment Type
Higher-efficiency systems — higher SEER2 ratings, two-stage and variable-speed compressors, variable-speed air handlers — cost more to buy and less to run, and in Florida that trade-off matters more than almost anywhere else, because the system runs for most of the year. A small efficiency gain multiplied by thousands of run hours is real money on the electric bill.
Equipment type matters too. A heat pump that heats and cools costs more up front than a straight-cool system with heat strips, but heats Florida's mild winters far more efficiently. Ductless mini-splits price completely differently again, per zone. Comparing quotes only makes sense when they are for the same type and efficiency class.
Factor 3: Your Ductwork
This is the factor online ranges ignore completely — and in Florida it can be the difference between a straightforward changeout and a much bigger job. New equipment connected to leaking, crushed, or undersized ducts wastes the investment every hour it runs, especially with ducts in an attic that reaches 140 degrees in summer.
That is why every replacement quote we write includes a ductwork evaluation. If the ducts are sound, we say so and the price reflects a clean changeout. If runs need sealing, repair, or replacement, you see that as its own line, with its own price, before you decide — never buried, never discovered mid-job.
Factor 4: Electrical Work and Panel Capacity
A new system has to be fed safely. The dedicated circuit and disconnect must be sized to the new equipment, and the panel needs the capacity to carry it. On older homes — especially those still on 100-amp service — a replacement can legitimately include electrical work or even a panel upgrade.
Because we run AC and electrical as two divisions of one company, that work is quoted in the same visit, by the same company that stands behind the whole job — not handed to you as a surprise second project after the AC is already sold.
Factor 5: The Home Itself
Installation labor is real cost, and it varies with the house: where the air handler sits (closet, garage, or a tight attic), how the line set runs, whether the pad and drain are reusable, and how much access the crew has to work safely.
Permits and inspections are also part of a legitimate Florida replacement. Permitted work is inspected work — an independent check that the install meets code — and it protects you at resale, when unpermitted equipment can stall a closing. A suspiciously cheap quote often gets cheap exactly here: no permit, no inspection, no paperwork.
Factor 6: The Old System
What is coming out affects what goes in. Older systems on phased-out R-22 refrigerant need their refrigerant recovered and handled under EPA rules — never vented — which is part of every replacement we do. Rusted stands, failed disconnects, and deteriorated drain lines from the old install may need correcting so the new system does not inherit the old problems.
The R-22 question also drives the repair side of the decision: a leak on an R-22 system means recharging with scarce, expensive refrigerant, which is one reason replacement so often wins on older equipment. Our AC replacement page lays out the full repair-or-replace framework.
Why Two Quotes Can Differ by Thousands
When quotes for the same house land far apart, the gap is almost never pure profit. Work through this checklist before assuming the cheaper quote is the better one:
- Equipment: same size, same efficiency class, same type? A basic single-stage system and a variable-speed system are not the same product.
- Ductwork: does the quote include the duct repairs your home needs, quietly exclude them, or never inspect the ducts at all?
- Electrical: are the circuit, disconnect, and any panel work included — or left for a second bill?
- Permits: is the permit pulled and the inspection included?
- Scope on paper: is everything itemized in writing before work begins, or is the low number a verbal starting point?
Questions to Ask Any Contractor — Including Us
A contractor who has done the homework welcomes these questions:
- How did you size the system? Ask to see the load calculation, not just the tonnage.
- What did you find in my ductwork, and is any of that work in this price?
- Does my panel have the capacity, and is any electrical work included?
- Is the permit included, and who meets the inspector?
- What happens to the old equipment and refrigerant?
- Can I see the full price, itemized, in writing before I approve anything?
How to Lower the Total Without Cutting Corners
The honest levers are scope and timing, not skipped steps. Choosing the efficiency class that fits how long you plan to stay in the home, fixing only the duct runs that actually need it, and planning a replacement before an August failure forces an emergency decision all keep the total down without gambling on quality.
Financing options can also spread a necessary replacement over time instead of forcing the cheapest possible equipment today — terms are put in writing before you decide. And once the new system is in, twice-yearly maintenance is what protects the investment: clean coils, a clear drain line, and a tested capacitor are how a Florida system reaches the top end of its life.
Common questions
Can you give me a ballpark price over the phone?
We can talk through the factors on this page, but a responsible price needs a load calculation, a duct inspection, and a look at your panel — in person. A firm phone price for a system nobody has measured is a guess, and guesses tend to grow once the old equipment is out. Our quotes are in writing before any work begins.
Why did my neighbor pay less for a replacement than my quote?
Probably a different job wearing the same name: different equipment size or efficiency, ducts that needed no work, a panel with spare capacity, or an easier install. Ask both contractors to itemize, and the difference usually explains itself line by line.
Does a higher SEER2 rating actually pay back in Florida?
More often here than in most states, because the system runs most of the year — efficiency is multiplied by thousands of run hours. Whether the top tier pays back for your home depends on your usage and how long you stay; we run the comparison honestly during a quote rather than defaulting to the most expensive option.
Are permits and inspections really necessary for a like-for-like swap?
Yes — replacements require permits in Wellington, and the inspection is an independent verification that the work meets code. Unpermitted work can also surface at resale and complicate a closing. We handle the permit and meet the inspector as part of the job.
Should I repair my R-22 system or replace it?
R-22 has been phased out of production, so every recharge uses scarce reclaimed refrigerant at rising cost — a leak turns into a recurring expense. On an older R-22 system, replacement is usually the honest recommendation; on a younger system with a minor fault, repair can still make sense. We show you both numbers so you can decide.
Does financing change the price of the job?
No — the job price is the job price, in writing, either way. Financing only changes how you pay it. Terms vary by lender and are put in writing before any work begins, so you can compare the real totals.
