Is water leaking from my AC a refrigerant leak?

No. Refrigerant leaves as a gas and does not puddle. Visible water is condensate that failed to drain.

Can I clear the drain line myself?

A vinegar flush at the cleanout helps with maintenance. An actual clog usually needs to be vacuumed out from the exterior termination, and attic setups are easy to make worse.

Why is water only leaking on humid days?

More humidity means more condensate. A partially restricted drain keeps up on mild days and overflows when volume rises.

How much water is normal outside?

Steady dripping at the exterior drain during operation is normal. Producing no water at all on a humid day suggests a blockage.

Why Is My Air Conditioner Leaking Water?

Your air conditioner removes a surprising amount of moisture from Florida air — often several gallons a day during humid weather. All of it is supposed to leave through one small drain line.

When water shows up indoors, the drainage path has failed somewhere. The cause is usually inexpensive; the damage from waiting is not.

The causes, in rough order of frequency

Clogged drain line

Biofilm and dust form a plug, usually at the trap or the exterior termination.

Full or failed condensate pump

Systems that cannot drain by gravity depend on a pump and its float switch.

Rusted or cracked drain pan

Older pans develop pinholes and leak even with a clear drain.

Thawing frozen coil

Melt water arrives faster than the pan and drain can handle.

Drain slope or trap problems

Sagging lines, reversed slope or a missing trap cause backups and gurgling.

Disconnected drain

A line bumped loose in an attic drains directly onto the ceiling below.

How serious is it?

What you see	Urgency
Damp spot in the secondary pan, system running fine	Schedule drain service soon
System shuts off and restarts after the pan drains	Float switch working; service the drain promptly
Active dripping onto flooring or cabinetry	Turn cooling off and request service
Water stain or sagging on a ceiling below an attic unit	Treat as urgent
Water near electrical components	Shut the system off at the breaker if safe, then call
Musty smell with visible standing water	Service the drain and have the pan and coil cleaned

Prevention that actually works

Annual condensate drain service, including the trap.
Vinegar flushes at the cleanout during heavy cooling months.
Filters that fit tightly, so less dust reaches the coil and pan.
Verified float switches on both primary and secondary pans.
Coil cleaning before fouling starts shedding debris into the pan.
A quick look at the exterior drain outlet now and then to confirm flow.

Never disable a float switch to keep cooling running. It is the only automatic protection between a clogged drain and a damaged ceiling.

The Florida angle

Condensate volume here is high for most of the year, and warm damp lines are ideal for biological growth. That combination makes drain clogs a maintenance item rather than a rare failure.

Attic air handlers, common across Gainesville's newer subdivisions, turn a routine clog into drywall repair. Annual drain service is the cheapest insurance available on a cooling system.
