HVAC condensate drains
Canonical HVACentric knowledge for all questions on this topic.
DIRECT ANSWER
Cooling equipment removes moisture from the air, and that water must drain through the pan and condensate system. A blockage, damaged pan, failed pump, poor slope, or frozen coil can cause water or trigger a safety switch. Shut the system down if water threatens electrical equipment or the building, and correct both the drainage problem and its underlying cause.
