If you looked at your phone today and saw a Heat Advisory with a 105° heat index, you’re not imagining how brutal that feels outside. But here’s what a lot of Krugerville homeowners don’t think about: your air conditioner is fighting that same heat, nonstop, all day long. And when an AC system gets pushed that hard for that long, it’s exactly the kind of stress that leads to condensation leaks you don’t see until there’s already damage.
I want to walk you through what’s actually happening inside your system on a day like this, and what to check right now while it’s still a small thing.
Why extreme heat causes AC leaks
Your AC doesn’t just cool air — it pulls moisture out of it, and that moisture has to go somewhere. Normally it drips into a condensate pan, runs down a drain line, and exits outside without you ever noticing.
On a 105° heat index day, your system runs longer and harder to keep up. More runtime means more condensation produced, which means more strain on that drain line and pan. If there’s already a small clog, a hairline crack, or a pan that’s slightly out of level, this is the kind of day that turns a minor issue into standing water — often right above a closet, hallway, or bedroom ceiling.
What to check today
None of this requires taking anything apart. Just a few minutes of looking:
- The ceiling below or around your attic unit — look for a soft spot, a new stain, or discoloration, even faint.
- Around the indoor air handler or furnace closet — check the floor for dampness or a musty smell.
- The condensate drain line outside — it’s usually a small PVC pipe near your outdoor unit. If it’s dripping steadily or not dripping at all when the AC is clearly running, that’s worth noting.
- Your thermostat — if it seems to be running constantly without really catching up, that extra strain matters on a day like today.
If you find a leak or a wet spot, here’s the honest truth: it looks small right now, but the water is already touching drywall, insulation, or subfloor you can’t see. That’s how a $200 problem turns into a mold and rebuild problem over the next week or two.
Why this hits so hard in North Texas
Heat advisory water damage isn’t just a coastal or humid-climate problem — North Texas summers create it too. We get long stretches of extreme heat that keep AC systems running nonstop for days at a time, with little relief overnight. That sustained runtime is exactly what turns a slow drip into real damage. Krugerville homeowners see this every summer, usually in the same handful of spots: attic units, closet air handlers, and older drain lines that were fine in spring but can’t keep up once the advisories start stacking up.
If you find water today
Don’t panic, but don’t ignore it either. Turn off the AC unit if it’s actively dripping into a living space, put a towel or shallow pan under the leak, and get a real look at how far the water has traveled. If it’s just started, you may have caught it early. If it’s been going a while, the moisture is probably already in places you can’t see without a moisture meter.
That’s really the whole game with water damage — surfaces dry fast, but what’s underneath doesn’t dry on its own, and that’s where mold gets its foothold.

I can’t promise a leak like this won’t be disruptive to sort out — but I can promise Josh will treat your home like he’d want his own treated, and be straight with you about what’s actually going on before any decisions get made. Merlene Mitigation is local to Pilot Point and serves Krugerville and the surrounding towns. Josh handles the inspections himself, so you’re talking to the person actually doing the work, not a call center. You can reach him by phone or text, whichever’s easier for you.
And if today isn’t an emergency but you’d rather be ready before one happens, our free guide, The First 24 Hours After Water Damage, walks through exactly what to do in that first critical window — worth five minutes now so you’re not scrambling later.
