If you’re in Gunter today, you already know: it’s brutal out there. With a heat advisory pushing us to 103° and a heat index near 112°, every AC unit in town is working as hard as it possibly can, right now, non-stop. And tonight, we’ve got a 30% chance of thunderstorms rolling through. That combination, a maxed-out AC system followed by a sudden storm, is exactly the setup that causes hidden water damage in homes that looked perfectly fine yesterday.
I want to walk you through why, and give you a few things you can check in the next hour that could save you a real headache tonight.
Why extreme heat alone can cause AC leaks
Your air conditioner isn’t just cooling air, it’s also pulling moisture out of it. That moisture collects as condensation and is supposed to drain out through a small condensate line, usually a PVC pipe near your outdoor unit or attic system.
On a normal day, that line handles the job fine. But on a day like today, with your AC running nearly constantly to keep up with 103° heat, your system produces a lot more condensation than usual, for a lot more hours. If that drain line has even a little bit of algae, dust, or debris built up (which is incredibly common and usually invisible), today is the kind of day it finally clogs.
When it clogs, the condensation has nowhere to go. It backs up into the drain pan, overflows, and starts finding its way into your ceiling, walls, or attic insulation, often for hours before anyone notices a stain or a drip.
Then the storms add a second problem tonight
Thunderstorms bring sudden shifts in air pressure and, obviously, a lot of water all at once. That combination puts stress on two things at the same time:
- Your gutters and roof flashing — heavy, fast rainfall exposes any small gap or clog that a light rain never would.
- Your AC system’s electrical and drainage components — pressure changes and power flickers during storms can trip a system that’s already been running flat-out all day.
Individually, either one is manageable. Together, on the same evening, they’re the exact scenario that turns a small, hidden leak into real water damage by morning.
What to check right now, before tonight
None of this takes special tools or expertise, just ten minutes and a flashlight:
- Check your AC drain pan and line. If you have an indoor unit in a closet or attic, look for any standing water in the pan or dampness around the line.
- Look for a slow drip outside. Your outdoor condensate line should be dripping steadily on a hot day like today. If it’s bone dry, that’s actually a warning sign, it may mean the water’s backing up somewhere else instead.
- Clear your gutters and downspouts. Make sure water has a clear path away from your foundation before the rain hits.
- Check your attic for existing staining if you have access, especially around any spot where ductwork or the AC unit sits.
- Know where your water shutoff is, just in case tonight brings more than a leak.
If you find standing water or a soft, damp ceiling spot, don’t wait to see if it dries out on its own. Surfaces dry fast, but the structure underneath can hold moisture for days, and that’s exactly where hidden mold risk starts.
If something does happen tonight
Here’s the honest truth: I can’t promise the heat and storms won’t cause a problem tonight. What I can promise is that if they do, the first priority is always the same, get the water out, get air moving, and stabilize things fast. That first day is about stopping the damage from spreading, not making every decision all at once. A full assessment can happen once things are stable, usually within 24 to 48 hours, and that gives everyone, including insurance, time to catch up properly.
Merlene Mitigation is a small, local operation, it’s just Josh, personally, on every inspection and every job. No call center, no rotating crew of strangers. That means lower overhead and fair pricing, and it means the person who shows up at your door is the same person who’ll see the job through.
Right now, through August 6th, we’re offering free water damage inspections for North Texas homeowners. If tonight’s storms have you even a little uneasy, or you just want a second set of eyes on something you noticed, reach out. Josh is easy to reach by phone or text, whichever’s easier for you.
And if things are calm tonight and stay that way, good. But it’s still worth grabbing our free guide, “The First 24 Hours After Water Damage”, so you know exactly what to do the moment something does happen, before you ever need it.
Stay cool out there, Gunter.
