Why should you regularly clean your ductwork system?

Does your air conditioning (AC) unit seem to be struggling this summer? Is it taking longer than usual to cool down your home? Chances are that it already needs cleaning and the problem may not lie with your AC at all, but rather with its ductwork system.

Moulds, dust, and debris may have built up in it which causes your air conditioner to work double time. If not given proper action immediately, it may cause wear and tear in your AC system and even cause health problems. Here, we’ll list down the important reasons why you should regularly clean your ductwork system. Read on.


Ducts are a major source of allergens and airborne pollutants

Duct cleaning is an important part of regular home maintenance for many homeowners. With time, dust, debris, and moulds can build up inside the ducts, which can be a major source of allergens and airborne pollutants. For this reason, regularly cleaning your air conditioner’s ductworks system in Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes is a must to avoid this.


Cleaning ductwork will increase the efficiency of your heating and cooling system

Air conditioner units work hard when they pump hot air out of a room and cold air in from outside. If there’s a build-up of dirt, moulds, and debris in the ducts, then it has to work even harder. This extra effort can cause wear and tear on both parts of the AC system, which can lead to costly repairs or replacements in just a few short years.

Even with the best maintenance, it is inevitable that some dirt and debris will build up inside of the ductwork over time. That’s why you should regularly clean your ductwork system; Because it’s a great way to increase the efficiency of your heating and cooling system. For an AC specialist’s help, call us at 07 3889 4508.


Dirty ducts can also cause respiratory problems such as asthma or allergies

Dirty ducts can cause mould and bacteria growth. If not maintained properly, these particles become a breeding ground for bacteria like Legionella Pneumophila, which kills more than two million people worldwide each year.

Therefore, if you don’t let a professional service your ductworks regularly, you run the risk of having respiratory problems such as asthma, allergies, and worst, the deadly Legionella Pneumophila.


A dirty filter will need to be replaced more often than a clean one

If you own an air conditioner, then you must know how important it is to clean the filter regularly. A dirty filter will need to be replaced more often than a clean one. If left uncleaned for long periods, not only will the air coming through the vents become less effective at cooling, but also over time will damage your unit.


You can breathe all the chemicals from your AC at least 5 days a week.

The air conditioner in your home is one of the most important appliances for keeping you cool and comfortable. But did you know that it can emit harmful chemicals?  Yes, it can and you might be wondering how you can breathe all the chemicals from your AC, here’s how.

The average Australian household has an AC on 5 days a week, meaning they are breathing potentially hazardous fumes over 30 times per month. The average person breathes around 15-20 litres of air per minute. So if we assume an average person has a respiratory rate of 18 breaths/minute, that means they are breathing about 900 litres or 9 cubic meters of air per hour.

If you spend time inside where the AC unit is running, then you’re likely to inhale nearly 2 cubic metres (or 4 gallons) of these airborne chemicals each day; And this is bad for anyone’s health, especially people with respiratory problems.

Isn’t this a valid reason to call a professional to service your AC’s ductwork system regularly? Let us know what you think in the comments.


Dust buildup on vents can block airflow and force your HVAC system to work harder

It’s easy for dust and other dirt to build upon the vents, especially if they are hidden in the ceiling or wall of your home. This buildup blocks airflow which forces your HVAC system to work harder, which increases utility bills by up to 25% and can shorten its lifespan.

You can avoid this by calling a professional to dust out the vents every few months. It will help keep your unit clean and free of harmful chemicals.


Our expert’s advice

It’s important to keep your AC in good working condition, and that means regularly cleaning its ductwork system. By getting it professionally serviced at least once a year, you can avoid harmful chemicals that may be collected in the unit.

Keeping your utility bills down is another benefit of regularly servicing your air conditioner in Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes, which also helps prolong its life. So, you aren’t buying a new one every few years. You should have your air vents cleaned at least once per year or every time you replace an air filter.

Give our HVAC professionals a call today for quality maintenance on your ductwork system before it becomes an issue. Let’s talk.

What To Do If Your Air Ducts Get Clogged?

Do you believe that your building is suffering from clogged air ducts?

Do you feel that the temperature in your rooms differ from one another?

Has there been a sudden spike in your energy bill recently?

Then it’s best to get an AC specialist look into your system. After all, a clogged air duct does not only spike up your energy bill; but it is also detrimental to a person’s health. Learn more about clogged air ducts, its ill effects and what you should do about it in this blog.


How does a clogged air duct affect your energy bill?

A clogged air duct prevents your HVAC system from reaching the set temperature on your thermostat. This prompts your unit to work even harder for it to properly cool the room. This causes your energy to spike up, too.


What You Can Do To Help Unclog Your Air Ducts

In order to unclog your air ducts, you should first identify the areas in your building where it is clogged. To do so, we recommend turning on your HVAC and checking each room to know which among these rooms are not properly blowing cool air.


Remove Items Blocking Your Vents and Air Ducts

Once you have narrowed this down, investigate if there are any wall arts, decor or furniture that may be covering the vents. Remove these items as well as the accumulated dust on these vents.


Inspect Your Air Filter

Get a closer look at your air filter. A dirty air filter can greatly affect the performance of your air duct. If you see it needs cleaning or replacement, immediately consult it with an HVAC specialist.

NOTE: For commercial cooling systems, it is highly recommended that air filters be replaced every month or two to ensure dirty air does not circulate in the rooms.


Check for damaged ductworks

It’s common for ductworks to get damaged over time, especially if it is not regularly checked and inspected by an HVAC professional. This may also be difficult for anyone because it requires training and skills. So, it is best to get this done by an AC specialist who will closely look into your ductworks for any possibility of leaks or damaged ductwork.

NOTE: Avoid fixing a damaged ductwork on your own because it may only lead to more serious problems in the future.


Examine Your HVAC System’s Zone Dampers

Commercial cooling systems for buildings often have zone dampers. These are installed for it to control the airflow into each room. For cool air to flow throughout all rooms, these dampers should always be completely open, but there are times when these can get stucked or at work wriggle loose on its own due to several factors.

If you are familiar with how these works, then you can adjust them manually. Otherwise, let the experts handle it for you. Call us on 07 3889 4508.


Call an HVAC System Expert

If you have checked on all of these things, but remain unsuccessful; then it’s best to get the help of a reliable air conditioning system professional. They are trained and skilled to inspect your AC’s ducts, filters, vents, and even dampers to ensure anything that blocks the airflow is removed. They can even tune-up your whole system so you will have a clean air duct.

Simple Ways You Can Minimise the Wear and Tear of Your HVAC Systems

Summer is coming and unless you get your AC ready, then you may be in for a very HOT month ahead. Let’s say you are ahead of time and got yourself a newly installed unit to brave this year’s summer, how are you taking care of it to ensure it will be delivering cost efficient cooling solutions to you for a long period?

Haven’t thought about it yet? We’re here to give you a heads-up so you can take good care of your new unit. Read on.


Regular Replacement of the Air Filter

You must have heard this time and again, but how seriously are you taking this advice?

Air filters are one of the most worked parts of your unit because it is designed to capture particles like pet dander, dust, dirt and debris. So, if you don’t get this cleaned or replaced; it can easily be clogged causing your unit to work extra hard. The result is higher energy consumption and increased heating and cooling cycles for your AC.


How often should you get this cleaned?


Get it cleaned every after change of season to ensure it is working at its absolute best.


Sealing the Air Ducts

Do you know that your air ducts can loosen at the seams and are prone to pictures and small holes over time? When this happens, it can create air leaks which may result in a major spike in your energy bill and additional wear to your capacitor, compressor and motor.

So if you start to notice that your AC unit is not cooling as usual, try to inspect if any of the air ducts remains sealed or if it has developed unwanted holes. If you see any, immediately contact an AC specialist who will look into it.


Install A Smart Thermostat

New models of air conditioning systems have smart thermostats installed in them. But for those with older models, upgrading yours to a smart model is a wise option as it helps you save as much as 10% on your energy bills. Moreover, it even allows you to control it via your mobile phones.


Clean the Vents Regularly

Just like your air filter, your AC’s vents may also be prone to dust, grime, debris and even pet hair. Eventually, this will buildup inside your vents and impede airflow.

Clean it regularly by using warm water and a few drops of cleaning solution. Wipe it with a clean microfiber cloth so you can clean the surface of the vent covers. As for the inside, you may use a wet-dry vacuum to remove the particle build-up inside it. However, there is nothing like the cleaning done by an AC specialist. So for best results, always ask the help of a professional.


Check the Outside Unit

Make it a habit to check your outdoor unit regularly. See that it is clear from all debris like weeds, grass, plants and other materials that may interfere with its ability to exchange heat with the outside air.

To clean your outside unit, just use a garden hose sprayer to rinse and clean the outdoor unit. As needed scrub it with a soft bristle brush. This will help in removing sticky substances such as tree saps on it. But if you are hesitant on how to do it, it is best to leave this to the experts. Schedule an appointment with us so we can check on your unit.


Keep Your Home Clean

You may not have realised it, but a clean home means lesser job for your aircon system, too. This is because little dirt and debris will have to be filtered in by your system. This makes it work less.

So one of the best and easiest ways to prevent your system from working harder than it should be, is to keep your house clean.



Nothing beats the benefits of a regular maintenance service performed on your aircon system. Afterall, AC technicians have been trained to thoroughly inspect, clean and tune up AC systems.

How Do You Choose the Right Air Conditioning System for Your Brisbane Offices

If you think choosing the right air conditioning system for your home is tricky, then finding the perfect one for your commercial area is even trickier. This is because of the additional complexity you need to consider when deciding the best HVAC solution to use.

In this blog, we’ll share some industry insights to help you plan and decide your air conditioning installation journey in Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes.


What is the ideal temperature for a productive office space?

A plethora of research suggests that office spaces should maintain between 20ºC and 26ºC of temperature, which is also mandated by the Compliance Code for Workplace Amenities and Environment.

This based on studies that anything lower or higher than this temperature will result in work inefficiencies including increased typo errors. So, it is important for commercial properties and office managers to ensure they achieve the ideal temperature range for their staff to remain productive.


How do you decide the best type of AC system for your office space?

Just like we have mentioned in other blogs, there is no absolute formula when choosing the right HVAC system. This is because the answer to this question rests on these factors;

  • Floor plan
  • Height of the floor to the ceiling
  • Orientation to the sun
  • Office layout
  • Number of people using the space
  • Type of equipments to be used

Based on these elements, your AC specialist can then recommend the right HVAC system to install in your commercial space.


Split, Ducted and Commercial HVAC Systems

For small offices, it’s typical for owners to opt for either a split or ducted system. But this is only recommended for shopping strips or offices converted homes. But for large offices, you’ll find commercial air conditioning systems to be more economical.


Why Choose Commercial Cooling Systems for Large Offices in Brisbane?

Unlike shopping strips and office converted homes, large offices (those with several desks and workstations) require a cooling system that has more power and wider coverage reach to ensure consistency throughout the office. This is the type of HVAC system used in buildings and skyscrapers as it supports dozens of rooms simultaneously.


VRV/VRF Air Conditioning: An alternative solution to large offices in Brisbane

With most offices not needing to run their HVAC system 24/7 to maintain its current temperature, an alternative solution to your air conditioning problem is the VRV/VRF systems.

It works by reducing the amount of refrigerant used whilst the temperature inside the room is stable. This helps in reducing the amount of energy used. The result is as much as 50% savings on your power use. This makes it the more popular option of many commercial areas.

Air Conditioning Cooling Problems and the Role Your Thermostat Plays

Thermostat is one of the most complex components of your air conditioning system. So it is not surprising if you find yourself frustrated when it becomes the cause of your HVAC system failure.

In today’s blog, we’ll be discussing some of the most common problems associated with your thermostat and what you can do about it.


How Does a Thermostat Malfunction Affect Your AC’s Performance

An inaccurate temperature assessment may result in your unit failing to identify whether your home has reached its desired temperature. As a result, the system may continue to struggle reaching this leading to faster wear and tear.


What are the common signs associated with a thermostat malfunction?

Here are the tell tale signs you need to go and check on your thermostat:


Inconsistent Room Temperature

If you feel cooler but your aircon is registering a different temperature, then this is a sign that your thermostat is not functioning correctly. It’s time to check if it is directly exposed to sunlight, near heat sources or cold spots.

If this is so, then it is best to relocate your thermostat to an isolated area far from these sources. Observe if the inconsistency with the room temperature remains the same. If not, then you have solved the problem. Otherwise, call a licensed AC specialist in Brisbane.


Failure to Properly Switch On and Off Your Unit

If you are manually switching on and off your unit, then it is already an indication that your thermostat has to be recalibrated. This has to be done so your HVAC will not need to work overtime. Call us on 0419 701 646.


Aircon Suddenly Shutting Down

This may be due to several factors, including wiring issues with your thermostat. So if you experience a periodic shutting down of your aircon, it is best to consult this matter with reliable aircon service and repair specialists in Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes . We will take action on this matter, immediately.


Simple To-Do Things to Help Fix Thermostat Issues

When you experience the above things with your air conditioning unit, it is best to consider the following:


Time for some thermostat cleaning

Dust and grime can build up inside your thermostat. When this happens, it can make your thermostat work inconsistently. Get an AC technician to do this for you to ensure your thermostat is clean and working efficiently. Talk to us.


Level the thermostat correctly

This is a common issue among old aircon models. So ensure your AC technician looks closely at it so it will be levelled correctly, otherwise it will not keep up the right temperature measurement.


Program defect on your thermostat

If you think thermostat issues only happen with old models, then you better think again. Although the levelling of your AC’s thermostat may not be a problem for computerised systems, a problem you need to deal with is the incorrect programming of some of these.

So, if your AC is running a smart thermostat, it is best to ask one of our AC specialists to help you with it. We are happy to help.


Improper thermostat installation

Another possible reason for a thermostat malfunction is improper installation. You’ll quickly identify if this is the case once you see loose wires on your thermostat. If you see one, avoid pulling out the thermostat on your own. Rather, call a reliable AC technician to handle this for you.



Thermostat plays an important function to the overall efficiency of your air conditioning system. Choose an experienced air conditioning expert to handle the installation, repair and maintenance of your system. Learn more about the different locations we service in Queensland.
