Why Ducted Heating Cleaning is a Winter Essential for Melbourne Homes

Ducted Heating Cleaning

Melbourne’s winter isn’t far off in Melbourne, and this brings cold winds and chilly nights.. If you’re lucky to have a ducted heating system for your home, you’ll want to stay as snug as possible when temperatures drop.

Have you been maintaining your heater? As breeding grounds for dust, mould, and other contaminants, you definitely don’t want your system spouting dust particles throughout your home!

This blog explores why ducted heating cleaning is important during the colder months, including the benefits to efficiency and health at home.

What Are Ducted Heating Systems?

Ducted Heating Systems

Ducted reverse cycle heating and cooling is known for whole-home comfort. If you want to heat or cool either a part of your home or the entire premises, you will have total control over the temperature of your property, no matter how cold it is outside!

The heating unit, thermostat, insulated ducts, grilles, and register vents work together to keep your home as cosy as it can be. So, how do these pieces work together?

When you turn it on, the fan pulls in cold air, passing it over a heat exchanger, which warms the air through gas combustion. This air is then distributed throughout your space. This warm air is pushed through the ducts that connect to vents in your rooms, and the return air grill sends this air back to the heater for it to recirculate.

What happens when your heater ducts are dirty?

These systems have a central heating unit connected to a network of ducts that deliver warm air to various rooms via vents. While great during the cold season, ducts gather dust, debris, and moisture over time, so you need to maintain them because:

It affects how well your heater can heat your spaces. If dust gets into the ducts, this can block the airflow and force the system to work harder to heat your property.

Your indoor air quality won’t be as good. Dirty ducts can circulate allergens such as dust mites, pollen, and pet dander throughout your home.

You’re more at risk of allergies or respiratory problems. Dust and debris in ducts cause mould and bacteria to grow, and these contaminants can be dispersed into the air.

Ducted Heating Cleaning: Why Call a Technician?

Ducted Heating Cleaning

You can clean your heater yourself, but it doesn’t compare to an experienced HVAC technician. There are many reasons to invest in a professional. After all, they know exactly what they’re doing.

The HVAC system will last longer

A professional can remove any debris buildup, but they also make sure that components are working as they should. Your heater will last longer, and you won’t be up for repairs that cost a fortune.

Professionals prepare your home

This includes sealing off any vents, setting up equipment, and protecting walls and floors. Technicians may use CCTV cameras to get a closer look at your ducts.

Technicians clean with specialised equipment

From high-powered brushes to vacuums, debris can be dislodged and removed easily.

Technicians sanitise properly

After the ducts have been cleaned, a technician can apply sanitising solutions to kill remaining mould or bacteria. If you have allergies or respiratory problems, this step is essential.

Putting a stop to mould

A lot of moisture leads to mould growth, and this affects your air quality. Professional cleaning services deal with mould safely.

Reliable inspections and quality testing

The air quality is tested, which can’t be done when doing it yourself.

Improve system performance

For consistent warmth in winter without malfunctions, professional cleaners use specialised equipment to clean all components.

You won’t use as much energy and save money

A clean ducted heating system needs less energy to operate since the airflow isn’t being blocked. You will not need to put them on full blast day and night to feel warm or notice any price hikes in your bills!

The savings on energy bills and repairs can offset the cost of cleaning services.​

How Can You Prepare Your Home for Winter?

There are quite a few things you can keep in mind. Schedule duct cleaning before the end of autumn, but also:

  1. Closely look at and replace filters: Check and replace filters for proper airflow and air quality.​
  2. Seal leaks: Seal any leaks in your ductwork to stop heat loss and improve energy efficiency.​
  3. Book in regular maintenance: If there’s a problem with your system (such as a leak), a HVAC technician can get on top of it.

So, DIY or professional cleaning?

It sounds cheaper and more convenient to do the job yourself, but you will be limited in terms of cleaning methods. DIY cleaning kits are available but fall short in removing deep-seated dust and debris. Cleaning mistakes also damage sensitive components of your heating system, so you’ll be up for an expensive repair if you do the wrong thing.

Overall, it is better to hire a professional. Professional duct cleaning services employ advanced tools and techniques to thoroughly clean your system. A HVAC technician, such as one at Aust Climate, accesses hard-to-reach areas (furnace fan or the motor) and handles all issues so your heater works safely.

Neglecting your climate system may lead to unit failure, so we recommend servicing it every 2-3 years. Our technicians are fully trained in servicing and repairing gas ducted heaters, evaporative coolers, and split systems. We also carry out carbon monoxide testing, so your system is safe!
