Call (325) 219-0005Water around the indoor unit traced to its source, whether a blocked condensate line, a cracked or overflowing pan, a failed condensate pump or a coil that froze and is melting, and fixed before it damages ceilings and floors.
01Leaking water
Where the water appears says a lot about which part has stopped carrying it away.
An air conditioner pulls a steady stream of water out of the air, and a blocked drain line sends it over the edge of the pan instead of away. Clearing the line and the pan stops it, and finding what blocked it keeps it from coming back.
With equipment in an attic, an overflowing or rusted-through pan can soak the ceiling below before anyone sees water. The pan, the drain and any safety switch above it need checking before the damage spreads.
Many systems carry a float switch that cuts cooling when water backs up in the pan or drain. The switch is doing its job, and the fix is clearing the drain it is reacting to, never bypassing it.
Where the drain cannot run downhill, a small pump lifts the water away. A pump that has failed, or one clogged with sludge, lets its reservoir overflow onto the floor.
02Drain or ice
Both put water on the floor. They are fixed in very different ways.
The system is cooling normally but its water has nowhere to go: algae and sludge in the drain line, a pan that has cracked or rusted through, or a condensate pump that has stopped. Clearing or replacing the part restores the path, and treating the line helps keep it open.
The coil froze, and when the system stops, the ice melts faster than the pan can drain it. Frost on the copper lines or weak cooling before the leak points here. The water is a symptom, and the airflow or refrigerant problem that caused the ice is the actual repair.
None of this repairs the leak. All of it limits the water damage while it waits to be seen.
Set the thermostat to off. A system that is not cooling stops producing water, which stops the overflow from growing.
Keep people and pets away from standing water near the unit, outlets or cords, and leave anything electrical that is wet untouched.
A ceiling that is bulging or dripping can hold a lot of water. Move people and belongings out from under it until it has been looked at.
If a float switch has shut the system off, it is holding back the overflow. Leave it in place rather than bypassing it to get cooling back.

03How it drains
Every cooling system has a drain, and most leaks happen somewhere along it.
Moisture condenses on the cold indoor coil and drips into a pan beneath it. From there a drain line carries it outside, to a floor drain or to a small pump that lifts it away. Warm, wet and dark, that line is an easy place for algae and slime to grow, and a slow build-up is the most common reason water ends up somewhere it should not.
Equipment above living space usually sits in a second, larger pan with its own drain or a float switch, so a failure in the first pan is caught before it reaches the ceiling. When those backups have rusted, been disconnected or were never fitted, the first sign of a blocked drain can be a stain overhead.
04Questions
Yes. Removing moisture from the air is part of how cooling works, and on a humid day a system can collect a surprising amount. It should all leave through the drain line. Water on the floor or the ceiling means that path is blocked or broken.
On many attic installations a secondary drain from the overflow pan ends somewhere easy to see, often above a window, so that water there is noticed. It usually means the main drain line is blocked and the backup is doing its job.
It is better switched off. A running system keeps producing water, and every hour adds to the overflow and the damage. Switching it off at the thermostat stops the water while the drain is looked at.
If it smells of burning, is leaking water, or the outdoor unit is humming without its fan turning, yes: switch it off at the thermostat. A system that runs but does not keep up can usually stay on until it is looked at.
A smell of gas, a carbon monoxide alarm, a burning electrical smell, or no heat or cooling in dangerous weather: urgent. A system that runs longer than it used to, a new noise or one room that is off: worth a visit soon, but not tonight.
