AC Blowing Warm Air in West Palm Beach, FLTop causes, real repair costs, when to replace instead
Warm air from the vents while the system runs almost always means the refrigerant circuit is the problem: low charge, frozen evaporator coil, or a tripped compressor. Less often it's a thermostat wired incorrectly or a stuck reversing valve on a heat pump. Typical fix: $200–$1,400.

Why ac blowing warm air happens in South FL homes
In order of frequency based on thousands of service calls in the South FL region — the most common issues first. Your West Palm Beach technician will diagnose the real cause in under 30 minutes.
Refrigerant leak
Compressor runs but can't move heat. Requires leak detection ($150), repair ($300–$700), and recharge ($400–$900).
Frozen evaporator coil
Ironically a warm-air cause. Ice on the indoor coil blocks airflow. Thaw and diagnose the underlying cause (dirty filter, low charge, blower failure).
Stuck reversing valve
Heat pumps only. The valve that swaps heating and cooling can stick in heat mode. Replacement: $600–$1,400.
Thermostat miswired
After a recent thermostat replacement, the heat/cool wires may be reversed. Easy fix — 30 minutes and a service call fee.
