Blowing, but not cold
Usually refrigerant, a failed capacitor, or a compressor that's given up. We test before we replace.
Running non‑stop
An undersized or dirty system never catches up in August. Often a duct or airflow problem, not the unit.
Water where it shouldn't be
Clogged condensate lines are the number‑one Miami service call. Fast to clear, expensive to ignore.
New noises
Grinding, screeching or hard starting means a mechanical fault. Shut it down and call — running it costs more.
Humidity you can feel
The thermostat reads fine but the house feels damp — a sizing and run‑time problem we can measure.
Bills climbing
Efficiency drops slowly. A tune‑up recovers most of it; past a certain age, replacement pays for itself.
