AC Running but Not Cooling in Nassau County?
Report the thermostat setting, indoor temperature, airflow and outdoor-unit behavior before trying another reset. Dispatch confirms the current appointment option, and diagnosis—not the symptom alone—determines the repair.
Separate immediate safety from the repair call
An HVAC appointment does not replace 911, the fire department or medical care.
Smoke, fire, sparking or a burning odor
Leave the area and call 911. Do not wait for an HVAC appointment, open equipment panels or repeatedly reset a breaker.
Water near electrical equipment
Keep people and pets away from the wet area and energized equipment. If there is an active electrical or fire hazard, call 911 first.
Dangerous indoor heat
Move to an air-conditioned location and check vulnerable occupants. Confusion, loss of consciousness, seizures or other suspected heat-stroke symptoms require 911—not an HVAC ETA.
CDC heat-illness guidanceIce or frost on the cooling system
Stop normal cooling operation and avoid chipping or heating the ice. Report where the ice is visible so a technician can evaluate airflow, controls and the refrigerant circuit.
Report what you observe
Details that help diagnose an AC that is not cooling
Do not open sealed panels, bypass safeties, add refrigerant or repeatedly reset a tripping breaker.
Air feels warm at every vent
Confirm that the thermostat is set to cooling and note whether the airflow is normal, weak or absent throughout the home.
Outdoor unit is not running
Report whether it is silent, humming, cycling or showing visible damage. Do not open the cabinet or repeatedly reset the breaker.
Indoor blower runs continuously
Share the thermostat fan setting, setpoint, indoor temperature and whether the air becomes cooler at any point in the cycle.
Ice appears on the line or coil
Stop normal cooling operation and allow a technician to evaluate airflow, controls and the refrigerant circuit. Do not chip or heat the ice.
Cooling works in only part of the home
Identify the affected floor, zone and vents. The cause may involve airflow, zoning, controls, distribution or equipment capacity.
Water appears near the air handler
Keep people away if water threatens electrical equipment. Report the leak location, whether the drain pan is overflowing and whether ice is present.

No-cooling diagnostic
The technician evaluates the thermostat call, accessible electrical components, airflow, temperature change, coils, drainage and refrigerant circuit to identify why cooling is unavailable.
The diagnostic is credited toward an approved repair. Dispatch confirms appointment-specific and after-hours terms. Diagnosis, parts, refrigerant handling, access, equipment condition and authorized scope determine the written repair price.

Do not rely on an uncertain repair time to protect someone from heat illness. Move to an air-conditioned location when needed and call 911 for suspected heat stroke.
- Stay hydrated and check on older adults, young children and people with chronic medical conditions.
- Use an air-conditioned public place or cooling center if the home cannot be kept safe.
- CDC advises that fans should be used only when indoor temperatures are below 90°F.
