Getting the Right Advice for HVAC in Humid Australia States

Australia is divided into 6 states (Western Australia, South Australia, New South Wales, Queensland, Victoria, and Tasmania) and 2 territories (Australian Capital Territory and Northern Territory). You can visit to learn more about these divisions. The climate of the country is diverse across these states and territories.

Of the 6 states, only New South Wales and Queensland can be said to be truly humid states. This is thanks to their proximity to the Pacific Ocean. So, in this section, we’ll provide expert advice for your HVAC for these humid Australian states.

Invest in Humidity Control

Depending on your HVAC system, your unit might be designed with a dehumidifying feature. While this might have its effect, it won’t produce the same results as attaching a humidifier. Therefore, it is advisable to get a humidifier attachment that will be added to your system.

With this installation, the humidifier will control the humidity in your space. The result will be a better atmosphere. Furthermore, you get to reduce damage caused by humidity.

In case you cannot get the humidifier attachment, you can get a separate dehumidifier. This device will also help to reduce your home’s moisture levels. An additional advantage is the reduction of negative effects on your unit’s air ducts. With these devices, condensation and mold growth are dealt with.

Clean your Air Ducts Regularly

Individuals living in humid climates do not have the luxury of leaving their air ducts uncleaned for a long time. Doing so can lead to the growth of mildew, mold, and other dangerous contaminants. Therefore, it is only right that you clean your air ducts from time to time.

Although this is something you can do if you are quite handy with tools, however, it is best left to the professionals. This is not just because they are trained for it; it is the best option to protect your health. Those areas might already have mold and/or mildew, therefore, contact with these contaminants is a health risk you don’t have to take.

When the ducts are clean, the growth of these contaminants is reduced. In addition, the air quality of your home is improved. So, if you’ve not cleaned those ducts in a while, pick up the phone and call a professional cleaner now.

Insulate the Air Ducts

Insulation is the counter -against condensation. With proper insulation, you can maintain a steady temperature in your home by reducing the loss of heat. Doing this will also prevent the buildup of moisture in the ducts.

Ensure your HVAC is not too Big

One of the key components when it comes to cooling or heating a space is that the system must be properly sized. In other words, the HVAC must not be too big or too small for the area it is meant to cover. When it comes to dealing with humid climates, a system that’s too big for the space has more negative effects than one that’s too small.

With a big HVAC, the unit will cool the space and quickly reach the set thermostat temperature. Once it does this, it automatically shuts off. After a while, it will come on once the room temperature is slightly warmer.

This pattern of operation is detrimental because the HVAC prevents the unit from removing moisture in the air. Therefore, if you don’t have an installed system, contact a professional to help you with the sizing to enable you to get the perfect size. If you have an installed unit, you might need to replace it with a smaller one.

Cooling Capacity
