AC Condensation Leaks in Aubrey, TX: 99° Heat Warning
If you walked past your hallway closet today and noticed a faint musty smell, or spotted a small dark ring forming on the ceiling below your attic AC unit, don’t ignore it. With heat index values hitting 108° in Aubrey today and tomorrow, your air conditioner is working harder than it has all year — and that extra strain is exactly when condensation drainage tends to fail first.

Here’s what’s actually happening inside your system, and how to catch a problem before it turns into water damage behind your walls or ceiling.

Why 99° Days Are Hard on Your AC’s Drainage

Every air conditioner pulls moisture out of the air as it cools your home. That moisture has to go somewhere — normally down a condensate line and out to a drain or the outside of your house.

On a mild day, that system barely notices the work. On a day like today, your AC is running nearly nonstop to keep up with the heat, which means it’s pulling more moisture out of the air than usual, for longer stretches of time. More condensation, more hours of runtime, more strain on a drain line that might already have a little algae buildup or a slow clog nobody’s noticed yet.

That’s the tipping point. A condensate line that’s been draining “just fine” for months can back up the moment it’s asked to handle a 99° day’s worth of moisture. When it backs up, that water has to go somewhere else — and “somewhere else” is often your ceiling, your closet, or the wall behind your unit.

Signs of an AC Overflow Worth Checking Today

You don’t need special equipment to catch most of these early. Just a few minutes and your own eyes:
- A musty or damp smell near vents, closets, or wherever your unit or ductwork runs — often the first sign, even before you see anything.
- Discoloration or a soft spot on the ceiling below an attic unit, or on a wall near a closet unit.
- Water pooling near the indoor unit or a drip pan that’s full or overflowing.
- Your AC running longer than usual without cooling the house like it should — sometimes a sign it’s struggling, not just the heat.
- A drain line that’s supposed to drip outside and isn’t — worth a quick look if you know where yours terminates.
Any one of these on its own might be nothing. But on a day this hot, it’s worth five minutes to check, because condensation leaks are sneaky. The surface can look dry while the insulation, drywall, or subfloor underneath is holding water you can’t see. That hidden moisture is exactly where mold risk starts.

What To Do If You Catch One

If you find active water: turn off the AC unit at the thermostat (not the drying equipment if you already have some running — but for a fresh AC leak, shutting down the unit itself is fine and often the right first move to stop more water from coming). Then get towels down, move anything valuable off the wet spot, and take a few pictures for your records.

Small, caught-early leaks are often a simple fix — a clogged line cleared, a full drip pan emptied. But if water’s been sitting for a while, or you’re seeing that ceiling stain and don’t know how long it’s been there, that’s worth getting a real set of eyes on it. Moisture behind a wall doesn’t announce itself, and “it looks dry” is never the same as “it is dry.”

AC Condensation Leaks in Gunter, TX: What to Check Now
If your air conditioner has been running nearly nonstop this week, you’re not imagining it. With the heat index climbing to 103° across North Texas, AC units in Gunter are working harder than they have all year — and that means more condensation, more strain on drain lines, and a lot more opportunity for water to end up somewhere it shouldn’t.

Here’s the part most homeowners don’t realize: a condensation leak rarely announces itself with a dramatic flood. It’s quiet. A little water finds a small gap, soaks into drywall or subfloor, and sits there. By the time you see a stain on the ceiling or smell something musty in the closet, that moisture has usually been working on your home for days or weeks.

Why AC Condensation Leaks Spike During Heat Waves Like This

Your AC pulls a surprising amount of moisture out of the air just to keep your home comfortable. On a mild day, that condensate drains off without much drama. On a 103° heat index day, your system is running longer cycles, pulling more moisture, and producing a lot more condensation than usual — all funneled through the same small drain line and pan that handle it on a normal day.

That’s when small problems turn into real ones: a partially clogged drain line, a pan that’s slightly out of level, or a condensate pump that’s been quietly struggling all season. Under normal conditions, it might never leak. Under this kind of heat load, it overflows.

What to Check This Week

You don’t need any special tools for this — just a few minutes and a flashlight.
- Look at the drain pan under your indoor unit (usually in the attic, a closet, or the garage). Any standing water, rust, or staining is a sign it’s already overflowed at least once.
- Check the drain line outside your home. It should be dripping steadily on a hot day like this. If it’s bone dry while the AC is running, that can mean the line is clogged and water is backing up somewhere else instead.
- Feel the ceiling below your attic unit for any soft spots or discoloration. Even a faint yellowish ring is worth taking seriously.
- Listen for your condensate pump, if you have one. If it’s not kicking on when it should, water can back up fast.
- Check closets, baseboards, and carpet near vents or the unit itself for a musty smell or a texture that feels damp when it shouldn’t.
If you catch any of this early, you’ve likely saved yourself from a much bigger repair. If you don’t catch it, hidden moisture behind drywall or under flooring is exactly how small AC leaks quietly turn into mold and structural damage — the kind of damage that costs a lot more to fix than it would have to prevent.

Why “It Looks Dry” Doesn’t Mean It’s Dry

This is one I talk about a lot, because it trips up even careful homeowners. The surface of drywall or subfloor can feel completely dry to the touch while the material underneath is still holding moisture. That hidden dampness is exactly what mold needs, and it’s exactly what a moisture meter and thermal imaging are built to find — because your hand and your eyes genuinely can’t.

So if you’ve had a leak, even a small one, and you’re not totally sure it’s resolved, that’s worth a second look from someone with the right equipment before you assume it’s fine.

If You Find Something

Don’t panic, and don’t wait either. A small AC condensation leak caught early is usually a simple, inexpensive fix. Left alone through a few more weeks of this heat, it can turn into warped flooring, stained ceilings, or worse.

I can’t promise every situation is simple — some hidden leaks turn out to be more involved than they look. But I can promise to walk you through exactly what’s going on, explain your options honestly, and never talk you into more than your home actually needs.

If you’re in Gunter or anywhere else in North Texas and something feels off, give Josh a call or send a text — texting is often the easiest way to reach him, especially if he’s already out on a job. He’ll get back to you with a real timeframe, not a runaround.

And if nothing’s wrong today but you’d rather be prepared than surprised, it’s worth grabbing our free guide, The First 24 Hours After Water Damage. It walks through exactly what to do the moment you spot a leak — before it becomes an emergency instead of a fixable problem.

AC Condensation Leaks in Aubrey, TX: What to Check Now
If you live in Aubrey and your AC has been running nearly nonstop this week, here’s something worth checking today, not next week: the little drain line that carries condensation away from your unit. With the heat index sitting at 104° through the weekend, that drain is working harder than it has all year, and it’s exactly the kind of thing that fails quietly until it doesn’t.

I want to walk you through what’s actually happening inside your system right now, what to look for, and what to do if you find a problem. Most of this you can check yourself in five minutes.

Why This Weekend Is Different

Your air conditioner doesn’t just cool air, it pulls moisture out of it too. That moisture has to go somewhere, so it drips into a condensate pan and drains out through a small PVC line, usually to the outside or into a floor drain.

When it’s 104° and your AC is running almost around the clock to keep up, it’s pulling more moisture out of the air than usual, and doing it more often. More condensation means more strain on that drain line. If there’s already a little algae, dirt, or a sagging section anywhere in that line, this is the weekend it backs up.

That backup doesn’t always announce itself. Sometimes it’s a puddle by the indoor unit. Sometimes it’s water tracking quietly into a wall cavity or a ceiling above a closet, and you don’t find out until there’s a stain or a smell.

What to Check Today
- The drain pan under your indoor unit. Standing water, rust, or a musty smell means it’s not draining the way it should.
- The condensate line itself. If you can see it, look for water sitting in the line or dripping somewhere it shouldn’t.
- Ceiling or wall stains near the unit, especially if it’s in an attic or a closet. A faint yellow-brown ring is often the first visible sign of a slow leak that’s been going on longer than you’d think.
- The float switch, if your system has one. It’s designed to shut the AC off before overflow happens. If your unit randomly stopped cooling, this could be why, and it’s actually doing its job.
- Any musty smell in a room near the unit. Nose knows before eyes do, most of the time.
If You Find Water

Don’t panic, but don’t wait either. A condensation leak caught early is usually a simple fix. A condensation leak left to run for a few days behind drywall or under flooring is a different problem entirely, and a much more expensive one.

Water doesn’t stay where you first see it. It follows gravity and gaps in framing, which means the wet spot on your ceiling might be nowhere near where the actual damage is spreading underneath.

If you’ve got standing water or a wall or ceiling that’s staying damp, that’s when it’s worth having someone actually look at it, not just guess. A moisture meter and a thermal camera can tell you what’s happening inside a wall without cutting into it, which saves you money and guesswork.

Why Speed Matters More Than People Realize

Here’s the honest truth: it’s not the first hour of water damage that costs you, it’s the ones you didn’t know were happening. In this heat and humidity, hidden moisture behind a wall doesn’t just sit there. It becomes exactly the environment mold needs to get started, usually within 24 to 48 hours.

That’s why, on any water damage call, the first move is always the same: get the water out, stabilize the area, get drying equipment running. Then reassess in a day or two once things are under control. It’s not complicated, it just has to happen quickly.

And if nothing’s wrong today but you’d rather be ready than caught off guard, we put together a free guide called The First 24 Hours After Water Damage. It’s the kind of thing worth reading now, on a calm day, so you already know exactly what to do if this heat ever does turn a small drip into something bigger.

AC Condensation Leaks in Providence Village: Heat Index 103°
If you’ve walked past your hall closet or utility room this week and caught a whiff of something musty, or noticed a small puddle near your air handler, don’t ignore it. With heat index values climbing to 103° across North Texas this week, air conditioners in Providence Village are working harder than they have all year — and that means condensation systems are working harder too. When they fall behind, water doesn’t stay politely on the floor. It finds its way into walls, subfloors, and ceilings before most homeowners even know there’s a problem.

Here’s what’s actually happening, what to watch for, and what to do before a slow drip turns into a much bigger repair.

Why extreme heat makes condensation leaks worse

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 and drains away outside. But when temperatures spike into the low 100s and the system runs almost nonstop to keep up, a few things happen at once:
- The system produces more condensation, faster, simply because it’s running longer hours
- Drain lines that were already partially clogged with algae or dust get pushed past their limit
- Condensate pans that were “fine” in spring can overflow under sustained summer load
- Attic units especially strain, since attic temperatures are already brutal this time of year
None of this means your AC is broken. It means it’s under more stress than usual, and small weaknesses that didn’t matter in April start to matter a lot in July.

The early warning signs (before you see standing water)

The tricky part about AC condensation leaks is that the damage usually starts before you notice anything obvious. Keep an eye out for:
- A musty smell near closets, ceilings, or the AC unit itself
- Soft or slightly discolored drywall near vents or the attic access
- A ceiling stain that seems to “appear overnight” — it didn’t, it’s just visible now
- Higher humidity than normal inside the house
- Your AC’s drain pan float switch tripping and shutting the system off (a good safety feature doing its job, not a false alarm)
If you catch any of these early, you’re in a much better spot than the homeowner who finds out three weeks later when a ceiling panel finally gives way.

What to do this week

You don’t need special tools for most of this:
- Check the drain line outside. There should be a steady, if small, drip when the AC is running. No drip on a 103° day is a red flag that something’s clogged upstream.
- Look at the condensate pan if it’s accessible. Standing water or visible algae growth means it’s due for cleaning, ideally by your HVAC tech.
- Have a licensed HVAC company flush the line and check the float switch if you haven’t had service this season. This part isn’t in our lane — it’s theirs, and it’s worth the visit.
- Watch ceilings and closets near your air handler for a week or two while the heat index stays high.
If water’s already gotten into the structure

Here’s the honest truth: it’s not enough for the surface to look dry. Water that’s gotten behind drywall or into insulation can sit there holding moisture long after the puddle is gone, and that’s exactly the environment mold needs. Once we spot moisture like that, the plan is straightforward — stabilize the area, get proper drying equipment running, and reassess in 24 to 48 hours once we know how deep it actually goes. That reassessment matters, because it lets us (and your insurance company, if you’re filing a claim) make good decisions instead of rushed ones.

I won’t pretend a drying setup is quiet or convenient. It isn’t. But I can promise to make it as least disruptive as possible, and turning that equipment off early isn’t a shortcut — it’s how a small leak turns into a much bigger, more expensive problem.

A quick and honest note: Josh isn’t a licensed Texas mold assessor, so if a situation calls for formal mold testing or remediation beyond what quick, proper drying can prevent, he’ll be straight with you about that and point you to the right licensed professional. What he will do is find the moisture, get it dry, and stay involved the whole way through.

You’re not on your own with this

If you’re in Providence Village or anywhere around North Texas and something feels off with your AC or you’ve already found water where it shouldn’t be, call or text Josh directly. Texting works great if that’s easier for you.

AC Condensation Leaks in Denton: Heat Index 104° Demands Action
If you’ve stepped outside in Denton this week, you already know: a 104° heat index isn’t just uncomfortable, it’s the kind of heat that pushes every AC system in North Texas to its absolute limit. And when your unit is running nearly around the clock to keep up, there’s a quiet side effect most homeowners never think about — until water is dripping through a ceiling or pooling behind a wall.

That side effect is a failed condensation drain line. And this time of year, it’s one of the most common (and most preventable) sources of water damage we see.

Why Extreme Heat Makes This Worse

Your air conditioner doesn’t just cool air, it pulls moisture out of it. That moisture has to go somewhere, so it drips into a condensate pan and drains out through a small line, usually PVC, that runs outside or into a drain.

When it’s 104° outside and your system is cycling nonstop just to keep the house livable, it’s pulling more moisture out of the air than usual, for longer stretches, day after day. That’s a lot more water moving through a drain line that’s often narrow, sometimes years old, and rarely inspected until something goes wrong.

Add in the algae, dust, and debris that build up in these lines over time, and you’ve got the perfect setup for a clog. Once the line backs up, the water has to go somewhere else. Usually that means overflowing the drain pan and finding the nearest path down, through a ceiling, along a wall cavity, into insulation you can’t see.

Why These Leaks Are So Easy to Miss

This is the part that catches people off guard. AC condensation leaks are quiet. There’s no burst pipe, no dramatic flooding, just a slow, steady drip that can run for days or weeks before it shows up as a stain on your ceiling or a musty smell in a closet.

By the time you see the evidence, the water has often already soaked into drywall, insulation, or subfloor. And moisture that sits in a wall cavity in July heat, with the AC running and humidity high, is exactly the environment mold needs to get started.

We’ve said it before because it’s true: it looks dry on the surface doesn’t mean it’s dry underneath. That’s where the real damage lives.

What To Check Today

You don’t need special tools to catch most of these early. Take five minutes this afternoon and check:
- The drain line outside — is it actually dripping steadily while the AC runs, or is it bone dry? A dry line during peak heat can mean it’s clogged and backing up elsewhere.
- The attic access or indoor air handler closet — look for staining, warped material, or a musty smell around the unit.
- Ceilings below any attic-mounted units — a small brown ring or soft spot is worth taking seriously, even if it’s small.
- The secondary drain pan (if your system has one) — if there’s standing water in it, your primary line has already backed up.
If you see any of that, don’t wait. A clogged line is a simple, inexpensive fix when it’s caught early. Left alone through another week of triple-digit heat index days, it becomes a much bigger, much more expensive problem.

If You Already Have Water Damage

If you’ve found active moisture, wet insulation, or a ceiling stain that’s growing, the priority is getting the area properly dried, not just wiped up. Surface-dry isn’t the same as structurally dry, and running a box fan at it isn’t a substitute for real drying equipment and moisture monitoring.

I can’t promise it won’t be a little disruptive to get it handled right, but I can promise to make it as least disruptive as possible, and to walk you through exactly what’s happening and why at every step.

We’re On Your Team

Merlene Mitigation is based right here in Pilot Point, and I’m currently offering free water damage inspections through August 6th for North Texas homeowners who want a second set of eyes before a small drip turns into a real problem. It’s Josh who shows up, Josh who does the inspection, and Josh who tells you honestly what you’re looking at, no upsell, no stranger subbed in.

If you’d rather text than call, that works too. Reach out whenever something feels off, even if you’re not sure it’s a big deal yet. That’s exactly the kind of call I want you to make.

And if nothing’s wrong today but you want to be ready in case it ever is, grab our free guide, The First 24 Hours After Water Damage. It’s the kind of thing that’s a lot more useful to read before an emergency than during one.

AC Condensation Leaks in Tioga, TX: Prevent Water Damage
If you’ve stepped outside in Tioga this week, you already know: the heat index is flirting with 99°, and it’s not letting up. Your air conditioner is working harder than it has all year — which means one small, often-overlooked part of your AC system is working harder too. And when it fails, it doesn’t announce itself with a loud bang. It just quietly drips, day after day, usually somewhere you can’t see.

That part is your condensate drain line, and this time of year, it’s one of the most common causes of water damage we see in North Texas homes.

Why extreme heat makes condensation overflow more likely

Your AC doesn’t just cool air — it pulls moisture out of it. All that humidity has to go somewhere, and normally it drains harmlessly outside through a small PVC line. But the harder your unit runs (and in 99° heat, it’s running almost constantly), the more condensation it produces.

If that drain line is even partially clogged — with algae, dust, or debris, which is extremely common — the extra volume can push it over the edge. Instead of draining outside, the water backs up into the drain pan. And if the pan is full, old, or cracked, it starts finding its way into your attic, your ceiling, or down inside a wall cavity.

That’s the part that worries us most: this kind of leak is often completely invisible until it isn’t. A stain on the ceiling, a musty smell in a closet, or a soft spot in the drywall can mean water’s been quietly working behind the scenes for days or weeks.

What to check today, while it’s still manageable

You don’t need special tools or training to do a basic check. A few minutes now could save you a much bigger headache later.
- Look at the drain line outside. Find the PVC pipe near your outdoor unit (or coming out near your indoor unit). Is water actively dripping from it? A steady drip is normal when the AC is running hard. No drip at all could mean a clog upstream.
- Check the emergency shut-off switch or float switch. Many systems have a small pan under the indoor unit with a float switch designed to shut the AC off if water rises too high. If your AC has randomly stopped cooling, this could be why — and it’s actually doing its job.
- Look for staining or sagging near your attic access, closet ceilings, or around vents. Especially if your indoor unit is in the attic, this is often the first visible sign.
- Feel around interior walls near AC lines for soft spots or a faint musty smell. Hidden moisture behind drywall doesn’t always show up as a visible stain right away.
If you find active water where it shouldn’t be, the priority is simple: get the moisture stopped and get air moving on the area as soon as possible. Don’t wait to see if it dries on its own — surfaces can look dry within a day while the structure underneath stays wet for much longer, and that’s exactly the environment mold needs to get started.

Why “it’s probably fine” is the wrong bet right now

We understand the instinct to wait and see. Nobody wants to make a big deal out of a small drip. But with heat this extreme, small drips add up fast, and the cost difference between “caught it early” and “found it three weeks later” is significant — both in dollars and in disruption to your home.

This is exactly the kind of thing we’d rather you catch on day one than day twenty-one.

We’re here, and we’re local

Merlene Mitigation is based right up the road in Pilot Point, and we serve Tioga and the surrounding communities. If you’ve found water where you shouldn’t have, or you’re just not sure what you’re looking at, we offer a free water damage inspection through August 6th — no pressure, no obligation, just an honest look and a straight answer about what’s going on.

You can call or text Josh directly — texting works great if that’s easier for you. When it’s your home on the line, you deserve someone who’ll tell you the truth, whether that means a same-day fix or just peace of mind that everything’s fine.

And if nothing’s wrong today but you want to be ready in case something ever does go wrong, we put together a free guide called The First 24 Hours After Water Damage. It walks through exactly what to do first, so you’re not scrambling to figure it out in the moment.

Stay cool out there, Tioga.

AC Condensation Leaks in Celina, TX: What to Check Now
If you live in Celina and your air conditioner has been running almost nonstop this week, you’re not imagining it. With the heat index pushing 110°, your AC isn’t just working hard, it’s working at the edge of what it was built to handle. And when a system runs that hard for that long, condensation has to go somewhere. Most of the time it drains away quietly. Sometimes it doesn’t, and that’s when a small drip turns into a ceiling stain, a warped floor, or a moldy patch you don’t find until it’s already spread.

Let’s talk about why this happens right now, specifically, and what you can check today before it becomes a bigger problem.

Why extreme heat causes AC condensation leaks

Every air conditioner pulls moisture out of the air as it cools your home. That moisture collects on the evaporator coil and is supposed to drain out through a condensate line to the outside. On a normal day, that system keeps up just fine.

But when the heat index hits triple digits, your AC runs longer cycles, more often, for more hours a day. That means more condensation being produced, more volume moving through that little drain line, and more chances for something to go wrong:
- The condensate line clogs. Algae, dust, and debris build up over time, and a heavy-use week is exactly when a partially clogged line finally backs up all the way.
- The drain pan overflows. Pans crack, rust, or simply weren’t sized for this much continuous output, so the overflow switch either fails or the water finds a way around it.
- Insulation sweats. Ductwork and lines running through hot attic space can develop condensation on the outside of the pipe, not just inside it, especially when the temperature swing between attic and duct is extreme.
Any one of these can send water into a ceiling, a wall cavity, or a closet floor, often above the AC closet or in the attic, where nobody’s looking every day.

Signs to check today, not next week

None of these take more than a few minutes:
- A ceiling stain, even a faint yellow or brown ring, especially under or near an attic unit
- A musty smell in a hallway or closet that wasn’t there before this heat wave
- Soft or spongy drywall anywhere below or beside the AC unit
- Standing water or a full drain pan if your unit is in a closet or attic you can access
- Your AC running constantly but the house not feeling as cool as it should
If you catch any of these early, you’re often looking at a fix, not a disaster. That’s the whole point of checking now while it’s still small.

Why “it looks dry” doesn’t mean it’s dry

Here’s the part people miss most: the surface of drywall or flooring can look and feel dry to the touch while the material underneath is still holding water. Drywall, subfloor, and insulation soak up moisture and hold onto it, and that hidden moisture is exactly where mold gets its foothold, usually within 24 to 48 hours in this kind of heat and humidity.

That’s the honest, sometimes uncomfortable truth about water damage. It’s rarely as simple as “wipe it up and move on.” The real question isn’t whether the surface is dry, it’s whether the structure underneath is.

What to do if you find a leak

Turn off the AC unit if you can safely do so, and put a towel or shallow container under any visible drip. Then get eyes on it, either yours or a professional’s, sooner rather than later. Day one is about stabilizing things: getting standing water out, keeping air moving, and figuring out how far the moisture actually traveled before you decide what needs to be repaired.

I can’t promise it won’t be an inconvenience to sort out. But I can promise to make it as least disruptive as possible, and to be straight with you about what’s actually needed and what isn’t.

If you’re in Celina or anywhere in North Texas right now

If you’re seeing any of these signs, or you just want a second set of eyes before it becomes something worse, give Merlene Mitigation a call or shoot a text. Josh personally handles inspections, so you’re talking to the person who’ll actually be looking at your home, not a call center. Being a small, local operation means lower overhead and fair prices, and it means one accountable person seeing your job through from the first look to the last fan.

And if nothing’s wrong today, good. Bookmark our free guide, The First 24 Hours After Water Damage, so if a leak ever does show up, you already know exactly what to do before help arrives.

AC Condensation Leaks in Prosper, TX: Why 110° Heat Demands Action
If you’ve stepped outside in Prosper this week, you already know: the heat index is sitting at 110° through Wednesday, and your AC is working harder than it has all year. What you might not know is that your air conditioner isn’t just fighting to keep your house cool right now — it’s also producing more condensation than usual, and that condensation has to go somewhere.

Usually, it goes exactly where it’s supposed to: down a drain line and out of your house without you ever thinking about it. But when a system runs nonstop for days in extreme heat, that drain line is under more stress than normal, and it’s exactly the kind of week these lines decide to clog, crack, or back up.

Why extreme heat makes AC leaks more likely

Your air conditioner pulls moisture out of the air as it cools your home. That moisture collects in a drain pan and exits through a small condensate line, usually a thin PVC pipe running out to the side of your house or into a drain.

When it’s 95° out, that system might run for a few hours a day. When the heat index hits 110°, it can run almost continuously — which means far more condensation moving through that same small line, day after day, with barely a break for it to catch up.

Add in the algae, dust, and debris that build up in most drain lines over a Texas summer, and you’ve got the perfect setup for a clog. Once that line backs up, the water has nowhere to go but back into the drain pan — and eventually, over the edge of it.

Where to look before it becomes a bigger problem

You don’t need any special tools to catch this early. A few minutes of checking can save you from a much bigger headache:
- The ceiling below or near your attic unit. A brown stain, a soft spot, or fresh discoloration is often the first visible sign of a slow leak that’s been happening for a while.
- Around your indoor air handler. If it’s in a closet or utility room, check the floor and baseboards for dampness.
- The condensate drain line itself. If you can see it, look for standing water backed up near the unit, or water dripping from the emergency overflow pan.
- Musty smell in a room you don’t use often. Sometimes your nose catches it before your eyes do.
None of these signs mean disaster. But all of them mean the water has already found somewhere it shouldn’t be — and that’s worth taking seriously, especially with days more of this heat ahead.

Why “it looks dry” doesn’t mean it’s fine

This is the part that catches people off guard. A ceiling stain can dry to the touch within a day, and it’s tempting to assume the problem solved itself. It didn’t. The surface dries first. What’s underneath — drywall, insulation, framing — can hold moisture for much longer, and that’s exactly where mold gets its start.

I’d rather you catch this early and it turns out to be nothing than wait it out and find out the hard way that it wasn’t.

What to do if you find something

First, get your AC serviced — a technician can clear the drain line and get your system draining properly again. That’s step one, and it’s usually a quick, affordable fix.

If there’s already visible water damage, staining, or that musty smell, that’s a separate conversation, and it’s the one I’d rather have with you before it turns into a bigger repair than it needs to be. A quick inspection can tell you exactly what’s happening behind that ceiling or wall, and whether it’s something to watch or something to address now.

We’re offering free water damage inspections this week

Given how many homes across North Texas are dealing with this exact issue right now, we’re offering free water damage inspections through July 29th for Prosper and the surrounding area. No pressure, no obligation — just an honest look and straight answers about what you’re dealing with, if anything at all.

If you’re in Prosper, Pilot Point, or anywhere nearby and you’ve spotted a stain, a damp spot, or just want peace of mind during this heat wave, give us a call. I’d rather look at ten ceilings that turn out fine than have one homeowner wait too long on the one that wasn’t.

And if nothing’s wrong today but you want to be ready in case it ever is, grab our free guide, The First 24 Hours After Water Damage. It walks through exactly what to do in that first day — before we ever get there.

AC Condensation Leaks: Why Extreme Heat Could Flood Your Home
If you live in Little Elm and your AC has barely shut off in the last 48 hours, you’re not imagining it. With a 114° heat index warning active today, every air conditioner in North Texas is working harder than it was built to run comfortably for this long — and that means one quiet, easy-to-miss problem is popping up all over the metroplex right now: AC condensation lines backing up and overflowing.

It sounds small. It isn’t. A backed-up drain line can dump gallons of water into your attic, behind a wall, or under your flooring before you ever notice a drop on the ceiling. So today, before you do anything else, I want you to go check on your unit. It’ll take five minutes.

Why extreme heat causes this specific problem

Your AC doesn’t just cool air — it pulls moisture out of it too. That water collects in a drain pan and runs out through a condensate line, usually a PVC pipe near your outdoor unit or a small drain near your indoor air handler.

When it’s 114° outside, your system runs almost nonstop to keep up. More runtime means more condensation, more volume moving through that little line, and more pressure on any weak point — a clog of algae, a kink in the line, a drain pan that’s already cracked or full. Under normal conditions, a slow drain might never cause trouble. Under today’s kind of extreme heat AC failure conditions, it overflows fast.

What to check right now
- The drain pan under your indoor unit (usually in a closet, attic, or utility room) — is there standing water, or has it overflowed onto the floor?
- The PVC drain line outside — is water actively dripping from it? A steady drip is normal when the AC is running hard. No drip at all, when you know the unit’s been running, can mean it’s clogged and backing up somewhere else instead.
- Ceiling stains, soft spots, or a musty smell near where your air handler sits, especially if it’s in an attic above living space.
- The float switch, if your system has one — it’s designed to shut the AC off before an overflow happens, but it can fail or get stuck.
If you find standing water or active dripping somewhere it shouldn’t be, turn the AC off at the thermostat and call an HVAC tech today — not next week. That part’s outside our lane, and I’ll always point you to the right pro for it.

Where this turns into water damage

Here’s the part that worries me most: condensation leaks are quiet. They don’t flood a room in one dramatic afternoon — they drip steadily into an attic, a wall cavity, or subfloor for days before anyone notices a stain or a soft spot. By the time it’s visible, the moisture has often already soaked insulation, drywall, or wood framing underneath.

And in this heat, warm, wet, dark spaces are exactly where mold gets a head start. Moisture is always the root of that problem — heat just speeds up the clock.

If you find water damage today

Day one is about stabilizing, not about having every answer. Get the water source stopped, get the standing water out, get air moving and drying equipment on the affected area, and reassess in 24–48 hours once things have had a chance to respond. That rhythm gives you — and your insurance company, if it comes to that — real information instead of guesswork.

One honest note: once drying equipment is running, it needs to keep running until the structure actually reads dry, not just looks dry. I know the fans are loud and disruptive. I can’t promise it won’t be — but I can promise to make it as least disruptive as possible, and turning equipment off early just invites the same problem back later, worse.

We’re local, and we’re keeping an eye on this heat wave

Merlene Mitigation is based right up the road in Pilot Point, and we’re watching this heat event closely because we know what it does to AC systems across Denton County and Little Elm. No crew, no call center — when you call, you’re talking to the person who’ll actually show up.

If you’ve found water where you shouldn’t have, or you’re just not sure whether what you’re looking at is a real problem, give us a call. No pressure, no upsell — just an honest look at what’s going on.
