Signs you need an AC repair now

In Florida humidity, small faults turn into big ones fast. Call if you notice any of these.

Warm air or weak airflow

Usually charge, coil, or blower related — and it gets worse with runtime.

Water where it shouldn’t be

A backed-up drain line can flood a closet or ceiling within hours.

Ice on the lineset or coil

Shut the system off and call — running it iced up can kill the compressor.

Breaker trips or hard starts

Electrical faults are a safety issue, not a wait-and-see issue.

Humidity indoors

Cool but clammy usually means sizing, charge, or airflow problems.

New noises or smells

Grinding, screeching, or burning smells mean stop and get it looked at.

Common questions

AC repair questions, answered.

How much does AC repair cost in Stuart, FL?

The diagnostic service call is a flat $149. Once the technician identifies the fault, you get a clear repair price before any work begins.

Why is my AC running but not cooling?

The usual causes are low refrigerant from a leak, a dirty condenser or evaporator coil, a failed capacitor or contactor, a frozen coil from restricted airflow, or a failing compressor. A diagnostic visit confirms which one it is.

Do you repair commercial AC systems?

Yes — rooftop units, split systems, and multi-zone setups for offices, retail spaces, restaurants, and light industrial buildings across all three counties we serve.

Should I repair or replace my air conditioner?

Repair usually makes sense on systems under about 10 years old, or when the repair costs well under a third of replacement. Older R-22 systems with a major failure are often better replaced — see new AC installation. We give you both numbers so you can decide.

What areas do you cover for AC repair?

We are based in Stuart, FL and repair systems throughout Martin County, St. Lucie County, and Palm Beach County.
