Five Common Signs Of A Mold Problem In Your Home (And More)
Does Your Home Have A Mold Problem? Here’s What You Want To Look For
Sure, everyone knows the clear signs of a severe mold problem at home: Big, ugly splotches, usually dark green or black, on a wall. Maybe it’s in the basement, or even upstairs if you’ve dealt with a leak.
But, that’s not the first sign of an issue. Far from it.
Mold tends to grow in out-of-the-way places, especially where there’s no light. So, you’re probably not going to notice a colony of spores right away when it’s growing behind the drywall or in a storage box.
In fact, by the time you do notice those significant visual signs, the problem’s already out of hand.
Instead, you need to keep an eye (and your other senses) out for those smaller and sometimes subtle clues that mold is growing in your home.
It can happen in any house, but homes that use mini split heating and cooling are even more at risk than others.
We’ll talk more about that a little later in this article. But first, we’re going through the common signs of mold in your home and some of the physical symptoms and health problems you can experience.
If you catch the problem fast enough, it’s possible to get rid of it on your own. And, with some extra care in the future, you’ll prevent it from coming back.
Five Telltale Signs Of A Mold Problem At Home
By the time you see mold growing on a wall or on furniture in your home,it’s already become widespread. Instead, look for these other telltale signs to catch a mold problem early on:
- Stale, Rotten Smell
- HVAC Smells
- Spots On Clothing
- Warped Walls
- Black Spots

Stale, Rotten Smell
You can’t see mold growing behind your walls or inside your HVAC system, but you’ll be able to smell it. Spores in the air will have a stale, rotten smell to them.
HVAC Smells
When it comes to heating and cooling, the odor caused by a mold colony has a specific name: Dirty Sock Syndrome.
That refers to the stale, cheesy smell you notice when your system circulates mold spores through the house. Check to see if the odor is more pungent around vents or near the air handlers of a ductless system.

Spots On Clothing
Mold can also grow on clothes, and you can spot it by watching for white or brown splotches on fabric that are squishy or fuzzy. It’s especially a problem if your clothes are still damp once they’re done in the dryer. Or if they’re tucked away in a box or drawer for a long time in a humid environment.
Warped Walls
Drywall is almost always used for interior walls in homes, and they’re porous. As a result, mold growing inside the wall will warp both sides of the drywall. So, even if the infestation is growing where you can’t see it, you’ll notice bulging and disfiguration on the side of the wall you can see.
Similarly, you may also notice bubbling and warping wallpaper.

Black Spots
Once you start noticing black spots on a wall, particularly near the ceiling or in a corner, you know you’ve got a mold problem quickly getting out of hand.
It’s easiest to spot on finished walls because it stands out against the paint. But, spots on the walls or floor of a dark, unfinished basement can blend in more easily with stonework and mortar.
Four Physical Symptoms Of Mold Exposure At Home
Exposure to excess mold in your home will start to cause health problems including:
- Allergy Symptoms
- Trouble Breathing
- Rashes And Blemishes
- Sinus Headaches
Allergy Symptoms
People with a mold allergy will respond to spores the same way people with seasonal allergies respond to pollen: Their immune system overreacts, and they experience runny noses, itchy eyes, a cough, and throat irritation.
Trouble Breathing
Breathing in a foreign and potentially toxic substance like mold spores can make you nauseous and trigger asthma attacks. Anyone with a respiratory problem such as COPD is also more vulnerable to difficulty breathing due to mold exposure.
Rashes And Blemishes
A rash from mold looks like any other rash triggered by an allergic reaction. So, you’ll want to look for some of the other signs we discussed. But, the brown or pink blemishes are often itchy with small raised bumps. And, they can make your skin dry, scaly, and sensitive to the touch.
Sinus Headaches
Headaches and sinus problems are common with mold exposure or being allergic to it. The problem is twofold: Inflammation from the allergic reaction, plus irritation of your respiratory system both contribute to sinusitis and related problems.

How Long Do Mold Spores Live?
Mold spores live for centuries as long as there’s organic matter for food plus a suitable place to cultivate. Mold spores on clothes usually live for a day or two. But, they’ll keep multiplying and form a colony that keeps growing if the conditions are right in your home.
Mold Spores And Ductless Mini Splits
Over the last ten years, we’ve discovered that ductless mini splits — particularly the air handlers — are prime breeding grounds for mold. These units trap bacteria and other organic matter, which serves as food.
Plus, they’re dark, warm, and damp — the perfect environment for a colony to thrive.
And, to make things worse, those spores spread through the air you breathe every time the system starts blowing warmed or cooled air back into the room.

For example, here’s a photo of an air handler we started cleaning. You can see the side of the coil we’ve treated versus the side we didn’t get to yet:
If you’ve had your mini split for more than a year, you should consider a deep cleaning. That’s especially so if you’re also noticing signs and symptoms of mold exposure in your Treasure Valley Home.

When most people think of getting sick from mold exposure, they think about feeling nauseous or generally ill. Maybe trouble breathing or allergy symptoms.
A general HVAC tune-up and cleaning will eliminate dirty sock syndrome if you’re lucky. But, if you have a ductless system, it’s essential to add a dedicated mini split deep cleaning to your strategy. In fact, these cleanings are important even if you don’t notice a bad smell yet.
The ideal temperature range for mold to grow in your home is 77 and 86 degrees Fahrenheit. Keeping the house cooler than that prevents growth. But, temperature is only one factor in spores or other organic toxins cultivating.
In general, the sweet spot for relative humidity in a home is between 30 and 60. No higher than 50 is ideal. That’s the range where mold won’t grow quickly. It also makes your home less attractive to cockroaches and other insects.
The effects of mold exposure or mold toxicity range from mild physical ailments to possibly even serious neurological issues. So, as you take steps to remove mold from your home, it’s also important to focus on healing the damage your body has taken as a result of exposure.
