Blocked, damaged or poorly trapped condensate path
Commercial symptom guide · ICY AC
Water on the floor is the end of a path—not the beginning.
Cooling systems intentionally remove moisture. That water must collect, drain and remain separated from electrical and building materials. Roof, plumbing and envelope water can imitate an HVAC leak.

What people notice
Reported symptoms
- Ceiling tile, floor or equipment cabinet becomes wet
- Leak appears only during cooling or certain weather
- Drain pan overflows or insulation sweats
What may interact
Plausible systems
Cold surface condensation from missing insulation or humid air
Roof, curb, flashing or plumbing leak
Coil freeze, airflow or control problem creating abnormal water
The first useful field packet
Collect evidence that can change the decision.
Record the building under the condition that produces the complaint. Keep direct observations, measurements, trade findings and hypotheses visibly separate.
- 01
Time, weather and operating state when water appears
- 02
Moisture path and affected materials
- 03
Drain pan, line, trap, pump and termination condition
- 04
Roof, plumbing and envelope exclusions where relevant
Avoid expensive loops
Do not spend past the proof.
- Clearing a line without finding why it failed
- Calling every ceiling leak an HVAC leak
- Closing the stain before materials and electrical exposure are assessed
Straight answers
Questions businesses ask first.
Why is my commercial AC leaking water?
Common paths include blocked drainage, failed pumps, bad traps, frozen coils, sweating surfaces and roof or plumbing leaks. The timing and water path distinguish them.
Can condensate leaks damage the building?
Yes. Water can damage finishes, insulation, equipment and electrical systems and can support microbial growth if the moisture source remains.
Is a ceiling leak always from the rooftop unit?
No. Roof, curb, flashing, plumbing and condensation sources can converge near the same opening. Trace the path under the condition that produces the leak.
