AC Leaking Water in Sanford, Florida
Water at the air handler or a ceiling stain below it is almost always the condensate drain — a clog, a full secondary pan, or a disconnected line — rather than a refrigerant problem. In Sanford's humidity, the drain line is the single most common service call there is.
What is most likely wrong
DIAGNOSIS| # | Cause | How common | What it looks like |
|---|---|---|---|
| 1 | Clogged primary condensate drain line | Very common | Algae and biofilm build up in a line that runs almost year-round; water backs up and overflows the pan. |
| 2 | Full or clogged secondary pan | Common | Drips appear only after the primary line has already failed. |
| 3 | Disconnected or sagging duct in the attic | Common | Wet insulation or a ceiling stain some distance from the air handler itself. |
| 4 | Frozen coil thawing | Common | A puddle appears after the system is shut off and built-up ice melts. |
| 5 | Cracked or rusted primary pan | Less common | A slow, small, constant drip on an older air handler. |
| 6 | Drain line pitched wrong or crimped | Less common | Standing water visible in a clear section of line even when nothing else is wrong. |
What you can safely check yourself
BEFORE YOU CALL- Find the drain line's outside termination (usually a PVC pipe near the foundation) and check whether it is actually draining.
- Look at the secondary pan under the air handler for standing water — if there is any, the primary line has already failed.
- If water is anywhere near an electrical panel or outlet, shut off power at the breaker first.
- In the attic, check for wet or sagging insulation along the duct runs, not just directly below the air handler.
Refrigerant, capacitors and the inside of an electrical panel are not homeowner jobs. A run capacitor holds a lethal charge even with the disconnect pulled, and refrigerant handling requires EPA Section 608 certification. In Florida this work is licensed under Chapter 489, Part I, F.S.; verify any contractor at the DBPR licensee search.
Why this happens in Sanford’s housing stock
LOCALThis is the routine Florida call, and Sanford’s climate is exactly why: a system pulling moisture out of the air for roughly 211 days a year produces a lot of condensate, and algae grows fast in a line that rarely runs dry. It shows up hardest in the two-storey stock — Lake Forest and the newer post-2000 townhome subdivisions like Windsor Lake and Riverview — where an attic or closet air handler leaks through a ceiling into living space below rather than onto a slab.
