Advance Air Tech Corp | Expert HVAC Repair in Miami, FL

This is a very common issue in our climate, often caused by refrigerant leaks, a frozen evaporator coil, or a failing compressor. The high humidity and constant demand can strain systems. Our technicians will perform a thorough diagnostic to pinpoint the exact cause—whether it's low refrigerant, a dirty air filter restricting airflow, or an electrical issue—and provide a clear, honest repair plan to restore your cool air quickly.

First, check your circuit breaker to ensure it hasn't tripped. If power is fine, the issue could be a faulty capacitor, a burned-out motor, or a problem with the blower wheel. Don't let this linger, especially in Miami's heat, as it can lead to further system damage and no airflow. Call us for an emergency diagnostic. We carry common parts on our trucks and can often repair the fan motor on the spot to get your system circulating air again.

Proactive maintenance is key. We recommend biannual tune-ups—once before the intense summer and once before the milder winter. Our maintenance service includes cleaning coils, checking refrigerant levels, inspecting electrical components, and ensuring the air handler and condenser are running efficiently. This preventative care helps catch small issues before they become major, costly repairs and keeps your system running reliably through the hottest days.
