Evaporator Coil Replacement in Port St. Lucie, FL

The evaporator coil sits inside your air handler and is where refrigerant absorbs heat from the air passing through it. When the coil develops a leak, refrigerant escapes and the system loses its ability to cool. Coils can also fail from formicary corrosion, which is caused by certain household chemicals reacting with the copper tubing over time. Replacement is the correct fix when a coil is leaking — patching refrigerant without addressing a corroded coil is a short-term answer that rarely holds.

When to Call

When You Need Evaporator Coil Replacement

  • Your AC runs constantly but the house never cools below 80 degrees.
  • A technician found refrigerant loss and traced the leak to the indoor coil.
  • You are seeing water overflow from the drain pan more than once in a season.
  • The system is repeatedly low on refrigerant despite being charged within the last year.

How It Works

Our Process for Evaporator Coil Replacement

  1. 1

    Leak Confirmation

    We recover remaining refrigerant, then perform an electronic leak test and nitrogen pressure test to confirm coil failure.

  2. 2

    Coil Removal

    We disconnect refrigerant lines, electrical connections, and drain lines, then extract the existing coil from the air handler cabinet.

  3. 3

    Coil Installation

    We install the matched replacement coil, braze the refrigerant connections, and pressure test the system before pulling a vacuum.

  4. 4

    Recharge and Performance Check

    We charge the system to manufacturer specifications, verify suction and discharge pressures, and confirm temperature split across the coil.

Port St. Lucie Context

Why this matters in Port St. Lucie

Formicary corrosion is a documented problem in coastal and near-coastal Florida homes, and Port St. Lucie properties within a few miles of the St. Lucie River are not immune. Household cleaners, off-gassing from building materials, and humidity all contribute to coil pinholes developing faster than the equipment age would suggest.

Straight Talk

About pricing & scope

Cost is driven primarily by the coil's tonnage, cabinet configuration, and whether the replacement coil is an exact match or a compatible substitute. Refrigerant lost during the failure is an additional material cost on top of the coil itself.
