Mold in your home isn’t just an eyesore, it poses serious health risks, from triggering allergies to aggravating asthma and other respiratory conditions. For Alberta homeowners, where varying temperatures and levels of humidity can create ideal conditions for mold growth, ensuring clean indoor air is crucial. 

One often overlooked source of mold is your home’s ductwork, and regular duct cleaning can go a long way in preventing mold growth by ensuring your air ducts stay free from moisture, dust and other contaminants.

In today’s blog the knowledgeable technicians at Action Furnace will go over the duct cleaning process, its many benefits, and how to tell when it’s time to schedule a cleaning before it’s too late.
Stay ahead of potential mold issues by making regular duct cleaning a part of your routine maintenance. Let’s go!

Mold - Yuck!

We all know mold is gross, and the appearance of it is never a good sign. But how much do you actually know about it?

Mold is a type of fungus that grows in damp, warm environments (like your air ducts), and the most common type of mold found in residential homes is black mold. Black mold poses serious health risks, ranging from mild allergic reactions, to severe respiratory problems, especially in individuals with weakened immune systems. And the key to preventing mold is by controlling its environment.

Conditions Mold Needs To Thrive

Mold requires the perfect combination of moisture, organic material and warmth to grow. And areas of your home with poor ventilation or high humidity, such as basements, bathrooms and air ducts create the perfect breeding grounds. 

Something as small as a leak or condensation build up within ducts can trigger mold growth. And when combined with high levels of dirt and dust, that act as that organic material source for mold to feed on, mold will quickly take hold.

Common Sources of Mold

Mold can appear in your home through various sources, often cleverly hidden until the growth becomes too big to ignore.

Common sources include: water leaks in plumbing or roofing, condensation build up on windows, poorly ventilated bathrooms, and wet basements. In your ducts, excess moisture is usually caused by inadequate insulation, or a malfunctioning heating or cooling system. 

Keeping these problem areas in check is crucial for mold prevention.

Do Your Ducts Need to be Cleaned? 

Ok, so by now we’ve established that duct cleaning is a great addition to your arsenal in the fight against mold. But how do you know when it’s time to schedule a cleaning?

Signs of Mold

Common signs of mold growth in your ducts include:

Odours

A persistent, musty smell when your HVAC system is running is one of the most common signs of mold in your ducts. The odour is often recognizable before the visual signs appear. 

Visible Mold Growth

We know this sounds silly, like of course visually seeing mold means mold is present. But it’s important to note where you’re seeing it. If you notice mold in other places like around your vents, or drip pans, then it more than likely is also in your ducts.

Increased Allergy or Respiratory Symptoms

If you or your family members begin to experience worsening allergy symptoms, getting sick more often or are having trouble breathing, mold in your ductwork could be circulating harmful spores throughout your home.

Notice one or more of these signs? We recommend following up with a DIY visual inspection. 

First, put on a mask. Seriously, we don’t want you getting to close and personal with that mold. Then using a flashlight, take a look in and around your ducts. Are there high levels of dust and dirt, are there cracks and leaks in the ducts themselves, has the insulation surrounding them seen better days?
All of these are signs that a thorough cleaning and inspection from the team at Action Furnace is in order.
