Why Is My HVAC Leaking Water?

Clogged Condensate Drain Line

This is the most common cause of AC water leaks in Columbus homes. Over time, algae, mold, and debris build up in the drain line, causing water to back up and overflow from the drain pan. Our technicians clear the drain line and treat it with algaecide to prevent recurrence. Cost: $80–$150.

Frozen Evaporator Coil Thawing

When your evaporator coil freezes (usually due to low refrigerant or restricted airflow) and then thaws, it releases a large amount of water that overwhelms the drain pan. You'll often see ice on the unit before the puddle appears. This requires diagnosing and fixing the root cause — low refrigerant or airflow restriction.

Cracked or Rusted Drain Pan

The drain pan sits under your evaporator coil and collects condensation. Older pans crack or rust through, allowing water to leak out regardless of whether the drain line is clear. Drain pan replacement typically runs $150–$300.

Disconnected Drain Line

Sometimes the condensate drain line simply comes loose from its connection point — especially in systems that have been serviced previously. This is usually a quick, inexpensive fix our technicians can handle on the same visit.

Furnace Condensate Issues (High-Efficiency Furnaces)

High-efficiency furnaces (90%+ AFUE) produce condensation as part of their operation. If the furnace condensate drain is clogged or the condensate pump fails, water leaks from the furnace unit. This is especially common in Columbus-area homes with newer high-efficiency heating systems.
