Condensation is normal for properly running air conditioning systems. Excess condensation, like sweating ducts and drips from outside the unit cabinet indicates a problem with your unit and points to an HVAC system issue that requires emergency HVAC repair service.
Why is my evaporator coil sweating excessively?
Icing of Evaporator Coils: The ice deposition over the evaporator will cause the temperature to decrease locally at air handler unit and may cause the sweating. Leakage of Ducts: The leakage of the cold air from the duct will increase the chance of sweating.
What causes excessive HVAC condensation?
Main causes for condensation occurring in your AC ducts include the temperature difference between the outside air and AC vent, improperly sealed AC ducts, and lack of insulation around these ducts. However, ductwork sweating can also be aggravated by factors like: Too much air moisture. Dirty air filters.
