Condensate Drain Problems

Air conditioners remove moisture from indoor air during operation. This moisture drains away through a condensate line.

When the drain becomes clogged, homeowners may notice:

• Water leaks
• Ceiling stains
• Increased humidity
• System shutdowns

Many modern systems automatically shut off when drainage problems are detected to prevent water damage.

 

First Steps to Take During an AC Emergency
