Capacitors are one of the most common AC failures in South Florida's heat. They help start the motors and keep them running. A failing capacitor causes hard starts, warm air, or complete shutdown.
Low refrigerant means your AC can't cool properly. It's almost always caused by a leak that needs to be found and repaired — recharging without fixing the leak is a temporary fix.
A frozen coil blocks airflow and stops cooling. Caused by dirty filters, low refrigerant, or restricted airflow. Regular maintenance prevents this common and costly issue.
A failing blower motor reduces or stops airflow. You may notice weak airflow, strange noises, or the AC running but not circulating air through the vents.
Electrical failures can prevent the AC from starting or cause erratic behavior. Worn contactor relays, blown fuses, or failed circuit boards require professional diagnosis.
