What is Mould?

Mould requires water and oxygen in order to grow. It’s one of the reasons why it can be found in so many varied places.

In terms of what it is, it’s a naturally occurring organism and it plays a major role in the ecosystem of the planet.

Of course, to most of us it doesn’t seem quite so special; it’s just a thing that annoys us and causes us problems around the house.

Sometimes it’s hard to see and can only be noticed by smell and other times it’s perfectly visible.

There are hundreds of types of mould and only an inspection can identify one type of mould from another.

Why is Mould a Threat to Your Health?

The Signs of Mould in Your Central Air Conditioner?

Musty Smells

The most obvious sign that there’s mould lurking in your air conditioner is the musty smell that’s so often associated with mould.

It’s sometimes the case that you can smell the mould before you even see any visible signs. That’s to do with how mould forms inside your AC unit.

And because air is being blown out of it, the smell can spread through your home relatively quickly.

If you do notice a strange musty smell anywhere in your home, don’t ignore it because it could be caused by the mould in your AC.

Visible Black Residue

Once visible signs of mould do start to show up, you should be able to identify them pretty much straight away. If you know what mould looks like, you’ll be able to spot it a mile off.

If not, what you should be on the lookout for is a black residue. It might not always come in full coverings of this stuff because it’s often very patchy, so keep that in mind when you’re on the lookout for it.

Health Issues

You should also be aware of the problems to your health that this problem can cause.

If there is mould in your unit and the AC is blowing air through the house, the chances are the mould will eventually start to impact on your health.

If you don’t take fast action to put this right, you will eventually start to experience problems with your breathing or you might develop a cough that won’t go away.

This could all be because of the mould in your AC.

Key Steps to Take

Make Changes to Your AC Settings

There is a range of settings that you can choose for your air conditioning unit, so it’s worth exploring them all in an effort to prevent mould becoming a problem in your home.

For a start, you should avoid the temptation to leave the unit inactive for long periods. Most units have an auto setting you can use, and it’s best to switch that on than to leave it inactive.

Mould usually begins to grow when the unit is not doing anything at all.

Tackle Dust

Too much dust inside your AC is another thing that can eventually lead to mould problems developing.

That’s why you should always be willing to check the AC unit and take action if you find that there is too much dust inside it.

Perform Regular Maintenance

Maintenance is important for a system like this. You can’t expect to keep it functioning at the same consistent level all the time without any intervention at all

If you don’t take the time to see what’s going on inside it and address any issues every few months, that will give stuff like mould the chance to develop.

If you don’t know how to do this, simply pay a professional to do the air conditioning maintenance work for you. It’s more than worth it.
