Warm air with the fan still running
A running indoor fan does not prove that the system is cooling. Check the thermostat mode and target, then note whether the air feels different from normal. Do not lower the target repeatedly to force a response. Tell us whether the problem began after a power interruption, a filter change, or a new noise.
If only one room is warm, look for a blocked supply or return grille without moving equipment. If the entire house is warming, say that first when calling. Stop checking when there is smoke, sparking, or water near electrical parts. Keep people away from the affected equipment.
Ice, indoor water, and repeated shutdowns
Visible ice means turn cooling off. Fan-only operation is an option only if the equipment is safe and the guide permits it. Water around the unit may come from melting ice or another problem, so keep belongings away without approaching wet electrical parts. Never chip ice or open a panel to inspect a coil.
Repeated breaker trips are a reason to leave the system off and get help. Do not keep resetting the breaker or try another switch to bypass the fault. Write down what happened and ask about current availability. For leaking or frozen equipment, the dedicated water and ice page gives safe next steps.
Signs it is an emergency
Cooling that stops during hot weather, a frozen coil, or water near the indoor unit can need prompt attention. Smoke, sparking, or water around electrical parts means you should keep clear and seek help.
If you smell gas, leave the house and call the gas company or 911 from a safe location, then us. Do not use switches or investigate the leak. If a carbon monoxide alarm sounds, get outside and call 911.
Safe steps before a service visit
Only make these checks when there is no sign of danger and you can reach the controls safely.
- Check that the thermostat is set to cool below the room temperature.
- Look at the breaker and accessible filter. Do not open equipment covers or repeatedly reset breakers.
- If the coil is frozen, turn cooling off and select fan on only if safe. Do not chip away ice. Keep clear of water near electrical parts.
Do not work on gas lines, refrigerant, or wiring. Write down an error code rather than trying to bypass a safety control.
