Common signs include your AC blowing warm air, ice forming on the refrigerant lines or evaporator coil, a noticeable hissing sound from the unit, and a sudden spike in your energy bills. If you suspect a leak, it's crucial to call for service promptly, as low refrigerant makes your system work harder and can cause compressor failure.

We generally recommend checking your filter every month and replacing it every 1-3 months. In DeBary, with our pollen and occasional dust, more frequent changes are often needed. A clogged filter restricts airflow, forcing your system to overwork, which can lead to frozen coils, poor air quality, and higher utility costs.

Short-cycling—when your system turns on and off frequently—is often caused by issues like a dirty air filter, low refrigerant, or a malfunctioning thermostat. Yes, it is urgent. This constant stopping and starting puts excessive wear on components, drastically increases energy use, and can lead to a complete system breakdown if not addressed.
