What can occur if condensate does not discharge properly?

When condensate does not discharge properly, it can lead to nuisance issues, which typically encompass a range of problems, including water damage, unpleasant odors, and potential pest infestations. Proper discharge is vital to prevent water from accumulating in areas where it shouldn't be, such as inside ducts, basements, or crawl spaces. These nuisance issues can cause discomfort and lead to additional maintenance concerns, impacting the overall functionality and safety of the HVAC system.

While other choices, such as mold growth and increased humidity, may also occur due to improper condensate discharge, they stem from the primary nuisance issues that arise when condensate is not managed correctly. Thus, the most direct and encompassing consequence of improper condensate discharge is the various nuisance problems it can create.
