Drain path
A restriction, poor slope, disconnected fitting or termination issue may prevent normal condensate removal.
CONDENSATE / WATER
Treat AC water as a location and safety problem first.
Cooling systems remove moisture. Water can come from a blocked or damaged drain, pan, pump, frozen coil or installation issue, but the visible puddle alone does not establish the cause.
Safe first observations
Do only what stays outside the equipment.
These steps collect useful evidence. They are not electrical, refrigerant, combustion or internal mechanical repair instructions.
- 01Stop operation if water is near electrical equipment or causing active property damage.
- 02Do not open panels or reach into wet equipment.
- 03Photograph the water location, drain termination and any visible ice from a safe distance.
- 04Use a qualified service professional for inaccessible drains, pumps, internal pans or recurring leakage.
Possible areas
One symptom can have several causes.
A qualified professional should connect any diagnosis to measurements, inspection evidence and a written scope.
Pan or pump
A damaged pan, failed condensate pump or unsafe overflow arrangement can allow water to escape.
Frozen coil
Ice that melts can overwhelm the drain area; the underlying airflow or refrigeration problem still needs diagnosis.
Service brief
Capture evidence before the appointment.
Do not include personal contact details in a public post. Keep model photos and the timeline with your private Project Passport.
- Thermostat mode, setpoint and observed indoor temperature
- System start/stop times and whether indoor and outdoor sections run
- Filter condition, visible ice, water, odor and unusual sound—without opening equipment
- Exact indoor/outdoor model numbers and system age when safely visible
- Water location, timing, drain/pump operation and any ceiling or wall damage
Shut off / urgent help signals
Water touching wiring, disconnects or panels; Ceiling sag or rapid structural damage; Burning odor or smoke; Repeated overflow after shutdown. For fire, gas, carbon-monoxide concerns or immediate danger, leave the danger area and call 911. During dangerous heat or cold, prioritize a safe conditioned location and local emergency guidance.
Questions for service
Make the diagnosis and scope comparable.
Where did the water originate?+
Ask the contractor to distinguish drain, pan, pump, coil icing and unrelated plumbing or roof moisture.
What overflow protection exists?+
Confirm the applicable float switch, auxiliary pan and termination arrangement.
What will be tested?+
The scope should state how drainage and system operation will be verified after repair.
