First Choice Plus Plumbing & Air provides evaporator coil inspection, cleaning, repair, and replacement for homes in Port St. Lucie and throughout the Treasure Coast. The evaporator coil is the indoor AC component that removes heat from your home’s air. When the coil is dirty, frozen, damaged, or leaking refrigerant, your air conditioner may blow warm air, run longer, have weak airflow, leak water, or stop cooling properly.
Since 2007, our HVAC team has helped local homeowners identify AC problems, understand their options, and restore dependable cooling. We inspect the system, explain what we find, and provide clear pricing before work begins.
An evaporator coil absorbs heat from indoor air as refrigerant moves through the AC system. The blower then sends cooled air through the ductwork and into each room. Because the evaporator coil works with the air handler, filter, refrigerant system, drain line, and ductwork, a technician should inspect the full cooling system before recommending a repair.
Schedule evaporator coil service if your AC is blowing warm or lukewarm air, airflow from vents is weak, ice forms on the indoor equipment or refrigerant line, cooling cycles take longer than usual, or water leaks from the air handler. A sudden increase in cooling costs, repeated short-cycling, or a musty odor near the indoor unit can also point to an airflow, drainage, coil, or refrigerant-related problem.
Turn the cooling system off if you see ice on the coil or refrigerant line, smell burning, hear severe mechanical noises, or notice water near electrical components. Continuing to run a frozen AC can cause further damage.
A frozen evaporator coil can be caused by restricted airflow, a dirty filter, a dirty coil, a blower problem, damaged ductwork, or a refrigerant-related issue. A frozen coil does not automatically mean the AC simply needs refrigerant. First Choice Plus Plumbing & Air checks the full system so the actual cause can be corrected.
An evaporator-coil problem can be connected to a restricted AC air filter, an air-handler problem, damaged ductwork, or refrigerant loss. When testing points to a refrigerant issue, we can provide AC refrigerant leak detection and repair.
First Choice Plus Plumbing & Air begins by inspecting the evaporator coil, air handler, filter, blower operation, condensate drain, refrigerant lines, airflow, and cooling performance. We determine whether the problem involves dirt buildup, restricted airflow, a drain issue, physical coil damage, or a refrigerant-related concern.
After the inspection, we explain the condition of the evaporator coil and give you the appropriate options before work begins. Depending on the diagnosis, service may involve cleaning the coil, correcting an airflow problem, repairing related AC components, addressing a refrigerant leak, or replacing the coil.

| What the technician finds | Recommended next step |
|---|---|
| Dirt and debris on an otherwise sound coil | Professional coil cleaning and airflow testing |
| Restricted filter, blower, or ductwork affecting the coil | Correct the airflow problem and test cooling performance |
| Refrigerant leak or corrosion | Confirm the source of the leak and review repair or replacement options |
| Major coil damage, unavailable replacement parts, or a costly repair on an older system | Compare coil replacement with a new AC system |
Evaporator coil replacement may be the better long-term choice when the coil has major corrosion, repeated leaks, extensive damage, or a repair that does not make financial sense for the age and condition of the system. If a new system is the better option, First Choice Plus Plumbing & Air provides a free estimate for air conditioning installation and replacement.
Check your AC filter monthly. Many heavily used Port St. Lucie systems need a standard one-inch filter replaced every 30 to 60 days, while media filters may have a different manufacturer schedule.
Yes, if you know the correct size, filter type, and airflow direction. Schedule service if the filter does not fit correctly, airflow remains weak, or you want help choosing a MERV rating.
The airflow arrow on the AC filter should point toward the air handler or HVAC equipment. Installing a filter backward can affect how it performs and may reduce airflow.
No. A higher MERV filter can capture smaller particles, but it may also add airflow resistance. The correct AC filter depends on your filter rack, return-air system, blower, and manufacturer recommendations.
A dirty AC filter can restrict airflow and contribute to a frozen evaporator coil. Ice can also indicate another AC problem, so turn the cooling system off and schedule service if ice appears.
If a clean, correctly installed AC filter does not restore normal airflow, the problem may involve the air handler, ductwork, evaporator coil, blower, or another AC component. First Choice Plus Plumbing & Air can inspect the system and explain the recommended repair.
Replacement-filter pricing depends on the filter size, thickness, type, and MERV rating. First Choice Plus Plumbing & Air explains the applicable price before work begins. Our AC tune-up is $125 as of July 2026.
Call First Choice Plus Plumbing & Air at 772-275-3760 to schedule AC air filter replacement in Port St. Lucie. If your system has no cooling, a burning smell, a water leak, ice, or a breaker that keeps tripping, request emergency AC service instead.

First Choice Plus Plumbing & Air provides Port St. Lucie and Treasure Coast homeowners with clear pricing before evaporator coil work begins.

We also inspect the air filter, blower, air handler, condensate drain, airflow, and cooling performance to identify the actual cause of the problem.
Not every frozen or dirty evaporator coil needs replacement. A dirty coil may need professional cleaning, while an airflow problem may require attention to the filter, blower, air handler, or ductwork. If the evaporator coil is leaking, corroded, or badly damaged, we explain whether repair or replacement is the better option for your AC system.

Evaporator coil service does not have one fixed price because cleaning, diagnostics, refrigerant-related repairs, and full coil replacement are different jobs. The final cost depends on the coil’s condition, access inside the equipment, the type and availability of the replacement coil, system warranty coverage, refrigerant work required, and whether service is needed after regular hours.
First Choice Plus Plumbing & Air inspects the AC system first, explains the recommended repair or replacement, and gives you pricing before work begins. Do not publish a coil price range unless it is a real range you are prepared to honor.
