Why Is My AC Leaking Water? Safe Checks and When to Stop the Unit
Where does an AC water leak usually come from?
An AC water leak means condensate is not following its intended drain path or abnormal condensation is forming on the unit or pipework. Checks commonly cover the drain, tray, installation fall, dirt, insulation and evaporator frost.
Safe leak checks
- ✓Locate the water
Identify whether it comes from the outlet, unit base, pipework, wall or ceiling.
- ✓Protect electrics and flooring
Keep water away from sockets, extension leads and appliances; address slip hazards.
- ✓Check the removable filter
Handle only safely removable parts; do not dismantle or reach inside the unit.
- ✓Stop for a persistent leak
Stop use and arrange inspection for heavy leaks, electrical risk or ceiling damage.
Common questions
Will clearing the drain always fix the leak?
No. The tray, installation fall, frost, insulation or mounting can also be involved, so the actual leak location matters.
Can I keep using a leaking AC?
Arrange attention promptly. Stop the unit if water approaches electricity, flows heavily or is soaking a wall or ceiling.
