AC PROBLEM · DIAGNOSIS GUIDE
Water in the wrong place is your AC's way of telling you something is wrong. Here's how to diagnose and fix it before it damages your floors or ceiling.
Turn the AC off until the leak is diagnosed. Put a bucket under it. If water is spreading across the floor or ceiling, call us same-day — water damage compounds fast.
Water under the indoor air handler or around the furnace? Usually a clogged condensate drain or a cracked drain pan.
Water dripping from a ceiling AC unit? Same root causes, but the ceiling damage compounds the urgency.
Water on the outdoor unit? Usually condensation — this is normal in humid weather. Excessive water means a refrigerant or drainage issue.
The most common cause by a wide margin. Algae, sediment, or debris blocks the drain and water backs up. We clear these with a vacuum and a cleaning solution. Cost: $150-$300.
Older systems develop pan cracks. Replacement is straightforward but the part can be expensive depending on the model. Cost: $250-$500.
A coil that froze and is now melting dumps water faster than the drain can handle. Address the underlying freeze cause.
In setups where the pan is below the drain line, a pump moves the water up. When it fails, water backs up. Pump replacement: $200-$400.
Sometimes a line just comes loose. Quick fix if that's what's happening.
Turn the AC OFF until the leak is diagnosed. Put a bucket under the leak. If the water is spreading across the floor or ceiling, call us same-day — water damage compounds fast.

“Water was coming through the ceiling from the attic unit. They got there in under an hour, cleared a clogged drain line, and saved me from a much bigger ceiling repair.”
