What are the Pros and Cons of Duct Cleaning?

Oh, how times change. Just when we started to marvel at the wonders of duct cleaning, we realised there were more questions than we first thought.

Is duct cleaning even necessary? Does it make a difference to the quality of your heating and cooling? What effect does it have on air quality? Is it worth the expense?

These are the kind of questions we encounter when thinking about our residential cooling and heating ducts, and we’re here to answer all of those queries.

How Your Air Ducts Work

Air ducts: those hidden conduits nestled within the structural elements of your home, mostly unseen and often forgotten until a problem arises. Yet they play a vital role in keeping our indoor environments comfortable, particularly in regions of extreme heat or cold.

So, how do they work? Let’s explore the fascinating world of air ducts together.

System Overview

The primary job of ductwork is to convey air, imbued with heating or cooling properties, to various parts of your home. Thus, it maintains a pleasant, controlled indoor climate.

Essentially, a heating, ventilation and air conditioning (HVAC) system has two main types of ducts – supply ducts and return ducts.

• Supply ducts: Supply ducts are responsible for delivering conditioned, temperature-controlled air into each room. Coming from the HVAC unit, either heated or cooled air is forced into these ducts and is then distributed via vent outlets situated across your dwelling.
• Return ducts: Return ducts ascertain that for every bit of air forced into the supply ducts, an equal amount of air is sent back to the HVAC system. These return ducts facilitate a constant circulation of air, dissipating the temperature differences and helping in maintaining a balanced atmospheric pressure within your home.

Ductwork Design and Material

The effectiveness of an HVAC system depends heavily on the ductwork design and the materials used. The ducts are typically made from materials such as fibreglass and metal, providing insulation and preventing conditioned air from escaping.

The design itself should allow for a smooth and efficient flow of air with minimal obstructions, enabling your HVAC system to function optimally.

 

The Role of Air Filters

Air filters in an HVAC system are often underestimated. However, they play an indispensable role in maintaining the air quality of your living spaces and optimising the overall system’s performance.

Here are their key roles:

• Air quality enhancement: Air filters help improve indoor air quality by trapping and removing airborne contaminants such as dust, pollen, mould spores, pet dander, and even bacteria. This is essential for maintaining a healthy indoor environment, particularly for those who suffer from allergies or respiratory conditions.
• HVAC protection: Air filters prevent dirt, dust and other debris from entering the HVAC system where they could cause damage or reduce efficiency. Unfiltered debris can settle on fan blades, motors and other mechanical parts, causing wear and strain over time. A clean filter protects these key components and can prolong the lifespan of your system.
• Energy efficiency enhancement: Clean air filters promote better airflow through the HVAC system. Dirty or clogged filters cause the system to work harder to distribute air, which can lead to increased energy use and higher utility bills. Regularly replacing or cleaning your air filters can help keep your energy costs lower.
• System performance maintenance: Air filters contribute to the optimal performance of your HVAC system, making sure it circulates clean, well-conditioned air throughout your living spaces. Essentially, they make sure that the air distributed to your rooms is clean, fresh, and temperature controlled.
• Prevention of coil icing: The evaporator coils in your HVAC system can become too cold and cause condensation around them. This leads to ice build-up if the air filter is clogged. A clean air filter prevents this potential issue.
• Odour reduction: Some air filters come with activated carbon that can reduce household odours, volatile organic compounds (VOCs), and other gaseous pollutants.

The Pros and Cons of Duct Cleaning

With all this talk about air duct cleaning and why one needs to keep their air ducts in top shape, one might think that it’s all unicorns and rainbows. But hold your horses – it’s only fair to also discuss the drawbacks as well as the positives.

Let’s take a look at the pros and cons:

Pros:

• Improved air quality: A strategic factor here is the air quality improvement that comes from the duct cleaning process, removing debris and contaminants.
• Enhanced system efficiency: Duct cleaning allows smooth airflow, which means your heating and cooling systems don’t need to work as hard, reducing energy costs.
• Prolong system lifespan: Regular maintenance can reduce the risk of mechanical failure and extend the life of the HVAC system.
• Health benefits: Reducing the concentration of dust mites, mould spores, and other contaminants in the air can contribute to maintaining good air quality. Thus, offering an environment less likely to trigger allergies.

Cons:

• Cost: With consideration to the duct cleaning cost, residential duct cleaning may not be for every budget.

With so few negatives, the benefits of necessity of duct cleaning are obvious.

The Importance of Duct Cleaning

Every day, air streams through your air ducts, coursing a path from your HVAC system to your favourite comfy room, and back again through the return air duct. Between the AC cranking during the summer to the ducted heating keeping us warm during winter, it’s a staple in maintaining good air quality.

But dirty ducts will result in poor air quality, which can impact the health of all inhabitants. For individuals who endure allergies, dust mites and mould spores found in the air can seriously trigger allergy symptoms.

On those scorching summer days, your cooling system depends on clean ducts to deliver refreshing waves of cold air.

But, if your air conditioning system or cooling ducts are choked with accumulated dust, pet dander, carbon particles, and who-knows-what else, the effort will not only strain the system but also churn out not-so-fresh air.

On the other hand, clean ducts and a well-kept HVAC system facilitate a flow of cleaner air, consequently helping to improve indoor air quality.

Identifying the Need for Air Duct Cleaning

So, how do you know if your ducts cried out for a good scrub? Simply put, if it’s been some time since your last duct cleaning, chances are, they’re a bit grimy.

Increased energy bills may also indicate the need for a check. After all, dirty ducts can decrease system efficiency, leading to increased energy costs. Presence of mould? Unexplained mechanical failure of your central heating system or air conditioner?

They are screaming for a helping hand from a professional duct cleaning service.

When to Schedule Your Air Duct Cleaning

When to schedule your duct cleaning depends on quite a few factors, like how many people live in the house, the presence of children and the elderly, whether or not you have pets, your general environment, the area you live in, and so forth.

Generally, a regular duct cleaning every three-to-five years should keep everything running smoothly.
