Quick Answer
Water by the air handler is usually a clogged 3/4-inch condensate drain, not a dying compressor. What the float switch does, what a drain clear costs, and when it is a coil leak.
Start here before you book service
- ✓ Shut the system off if water is hitting drywall, flooring, or a ceiling below.
- ✓ Look at the float switch in the drain pan or trap before you assume the compressor died.
- ✓ A drain clear on a residential system typically lands $150 to $275 with a flush and a treatment tab.
- ✓ Ice on the copper suction line is a frozen coil, not the same repair as a clogged PVC line.

Every hour a Wesley Chapel system runs, the indoor coil wrings water out of the air. That is latent cooling, and it is most of the work in a climate that sits in the mid-70s dew point for months. A 3-ton unit can send 4 to 8 gallons a day down a 3/4-inch PVC line to a stub on the side of the house. When that line clogs, the water has nowhere to go except the secondary pan, the closet floor, or the drywall under an attic air handler.
Homeowners search AC leaking water and picture a refrigerant leak. Refrigerant is a gas or oil stain, not a puddle. A puddle is condensate. The repair is almost always the drain, the trap, or the float switch, handled on our AC repair route.
Water by the air handler
Open the closet or pull the attic hatch and look before you call it a new system. Standing water in the primary pan, a wet ring on the concrete, or a stain on the ceiling below an attic unit all point at overflow. The coil is doing its job. The pipe is not.
In Seven Oaks and Meadow Pointe the air handler often sits in a garage closet, so you see the puddle first. In Epperson and Mirada a lot of handlers sit in the attic. Those overflow into the secondary pan, then onto the ceiling if the pan drain is also blocked. That is why a quiet leak on a Tuesday becomes a drywall claim on Thursday.
The float switch shut the system off
Most systems here have a safety float in the pan or the trap. When water rises, the switch opens the 24-volt circuit and the outdoor unit dies. The house gets warm. There is no loud failure. People think the compressor quit.
If the indoor blower is silent and there is water in the pan, lift the float (or pour the pan out) only as a temporary test, then shut the breaker back off if water returns. Running the system with a defeated float switch is how you flood a closet. We reset the switch after the line is actually clear.
Algae in the 3/4-inch PVC
Florida condensate is warm, dark, and sitting in a pipe that never fully dries. Biofilm grows from the trap out to the exterior stub. You can see it as green slime at the termination on the side of the house. Inside the trap it looks like wet felt. That plug is enough to back the coil up in a single afternoon of runtime.
A garden hose from the outside stub pushes the slime back into the pan. That is the wrong direction. The clear that holds is a wet-vac at the exterior termination, a flush of the trap, and a treatment tab in the pan so the next month of humidity does not rebuild the plug in a week.
What a drain clear costs
On a standard residential system, a condensate drain clear with a float-switch check typically lands $150 to $275. That is the same band we publish on the Wesley Chapel repair page. It covers the vacuum, the trap, the tab, and a written note that the line flowed. It does not cover a cracked pan, a rusted secondary, or a refrigerant leak that is a different job.
If the ceiling is already wet, say that on the phone. We will tell you whether to stop the system and put a bucket under the pan before we roll. Same-day is common when the route is open. Office hours are Monday through Friday 8 a.m. to 6 p.m., Saturday 10 a.m. to 4 p.m.
When it is a pan versus a coil leak
A clogged drain leaves fresh water, no oil smell, and a wet pan. A frozen coil leaves ice on the suction line and a flood when it thaws. A refrigerant coil leak leaves oil staining, ice that comes back on a clean filter, and warm supply air. Those three get mixed up in every AI overview because they all wet the same closet.
If we find ice, we thaw first and then find the restriction or the leak. If we find oil at a return bend, that is not a $200 drain. We will show you both numbers on the invoice so you are not paying for a flush that cannot fix a hole in the coil.
How to keep the line open
The spring AC maintenance visit is where we flush this line before June. Homes that skip a year are the ones that call on the first week of real humidity. A tablet in the pan between visits helps. Pouring bleach down the indoor trap without pulling the slime out just moves the plug.
