Evaporator coil replacement cost in Florida typically runs about $1,800–$3,000 out of warranty and about $900–$1,500 when the coil is covered by the manufacturer's parts warranty, because you still pay for labour and refrigerant (market estimates). On an older system, compare that price with a full replacement. Pinellas Cooling & Heating in Pinellas Park gives free estimates on new systems.
The evaporator coil is the cold coil inside your air handler. Warm air from the house passes over it, the refrigerant inside absorbs the heat, and moisture condenses on the fins and runs to the drain. When a coil leaks, there's no reliable patch: the fix is a new coil, or a new system. This page explains what each option costs and how to decide.
| Scenario | Typical cost (market estimate) | Source |
|---|---|---|
| Coil under manufacturer parts warranty (you pay labour, refrigerant, filter-drier) | $900–$1,500 | Liberty Air and Electric (Florida) |
| Coil out of warranty, installed | $1,800–$3,000 | Liberty Air and Electric |
| Evaporator coil, local contractor figure | $1,400–$2,600 | I Care Air Care, via Local HVAC Guide |
| Labour only, warranty coil, contractor price book | $1,348 plus refrigerant | Home Therapist |

So how much does it cost to replace an evaporator coil in AC systems around Pinellas Park? Most out-of-warranty jobs fall somewhere around $1,800–$3,000. The spread comes mostly from three things: the coil itself, how much refrigerant the system needs, and how hard the air handler is to reach. If the whole indoor unit is rusted or failing, compare our guide to air handler replacement cost.
Often the part is, but the labour and refrigerant usually aren't. Many major brands cover coils for 10 years when the system was registered after installation, and less if it wasn't. Check the label on your air handler for the model and serial number and look it up on the manufacturer's site, or ask us to check. Even with a covered coil, expect to pay for labour, refrigerant, the filter-drier and any other parts, which is why warranty jobs still run about $900–$1,500 in Florida.

The main cause is formicary corrosion: tiny pinhole leaks that form in copper tubing when moisture combines with certain chemicals in household air. A coil in Florida is wet for most of the year, which gives corrosion plenty of time to work. Over years, pinholes let refrigerant escape slowly. Signs include the system cooling less and less, longer run times, ice on the refrigerant line, and a hissing or bubbling sound at the air handler.
A technician confirms a coil leak with electronic leak detection, bubble testing or a nitrogen pressure test. Topping off refrigerant without finding the leak only delays the problem, so ask how the leak was found before you approve a coil.
A simple way to frame it: multiply the repair cost by the system's age. If the result is well over about $5,000, replacing the system usually makes more sense.
| Situation | Usually the better choice |
|---|---|
| System under about 8 years old, coil under warranty | Replace the coil |
| System 8–12 years old, coil out of warranty | Get both prices and compare |
| System 12+ years old, or other repairs coming | Replace the system |
| Older system using R-22 refrigerant | Replace the system |
Example: a $2,400 coil on a 12-year-old system gives 2,400 × 12 \= $28,800, well past the threshold. The same coil on a 5-year-old system gives $12,000, but if the coil is under warranty the real cost drops sharply. For full-system prices, see our guide to AC unit cost by size.
Sometimes, but it's a short-term choice. Leak sealants exist, but contractors disagree about them, and they can't fix a coil that's corroding in many places. Recharging without fixing the leak means paying for refrigerant again. If budget is tight, ask for an honest estimate of how long a repair will last and compare that with financing a replacement.
Yes. We offer GoodLeap financing, on approved credit, for larger repairs and replacements. If you choose a new system, a qualifying high-efficiency system may also earn a Duke Energy rebate when the program's requirements are met; we can explain those when we quote. Estimates for new systems and replacements are free.

It varies with corrosion, maintenance and air quality in the home, so there's no fixed lifespan. Many coils last as long as the system; others develop leaks earlier. Regular maintenance helps us spot early signs.
Yes, for new systems and replacements. A coil repair starts with our $125 diagnostic, credited toward the repair if you go ahead.
Our licensed technicians fix AC units that are not cooling, leaking, freezing up or tripping breakers, on all major brands. We find the real cause and explain the price before any repair starts.
