How Humidity Affects Your Air Conditioning System and Indoor Comfort, Vital Air Conditioning Services

Understanding Humidity & Its Dynamics

Humidity refers to the amount of water vapour present in the air. In Australia, where climates can range from dry and arid to tropically moist, managing indoor humidity levels can be a significant challenge.

The comfort range for indoor humidity is typically between 30% and 50%. When levels deviate from this range, it can compromise not only comfort but also the efficiency of your air conditioning unit.

The Effects of High Humidity on Air Conditioning Systems

High humidity levels can have a detrimental impact on air conditioning systems in several ways:

Increased Energy Consumption

Air conditioning units have to work harder in high humidity because they must cool the air and remove moisture. This double duty can lead to significant increases in energy consumption, as the system uses more electricity to achieve the desired indoor temperature and humidity levels.

Reduced Comfort

High humidity can make the air feel warmer than it actually is. As a result, even when the air conditioner is lowering the temperature, the extra moisture can leave you feeling hot and sticky. This scenario often leads users to lower the thermostat even more, which again increases energy use and costs.

Strain on the System

When an air conditioner is forced to operate under the stress of high humidity, it can lead to wear and tear on its components. This strain can reduce the lifespan of the unit and lead to frequent breakdowns and repairs.

Mould and Mildew Growth

Excessive moisture is a breeding ground for mould and mildew, which can develop within the air conditioning system itself or in the ductwork. This not only harms the system but can also pose health risks to the occupants of the building by degrading indoor air quality.

How Low Humidity Affects Air Conditioning and Comfort

Conversely, low humidity levels, while less common in certain parts of Australia, can also affect air conditioning systems and comfort:

  • Health Issues: Low humidity can dry out mucous membranes in the nose and throat, which can lead to discomfort, respiratory problems, and increased susceptibility to colds and other infections.
  • Damage to Building Materials: Just as high humidity can be damaging, low humidity can cause wood to shrink and crack, including hardwood floors, cabinetry, and furniture, potentially leading to costly repairs.
  • Static Electricity: Reduced humidity levels can increase static electricity, which not only causes minor shocks but can also damage electronic equipment.

Managing Humidity for Optimal Comfort and Efficiency

At Vital Air Conditioning Services, we offer solutions designed to manage indoor humidity levels effectively, enhancing both comfort and system performance:


Proper Sizing of AC Units

One of the most critical steps in ensuring effective humidity control is to have an air conditioning system that is correctly sized for your space. An oversized unit will cool the air quickly but without adequately removing moisture, leading to discomfort and other humidity-related problems.

Use of Dehumidifiers

In areas with particularly high humidity, integrating a dehumidifier with your air conditioning system can help maintain ideal humidity levels, thereby improving comfort and reducing the workload on your air conditioner.

Regular Maintenance

Regular servicing of your air conditioning unit can help prevent issues related to humidity. Maintenance checks include ensuring that the system is functioning efficiently and that components such as coils and filters are clean and clear of obstructions.

Smart Thermostats

Installing a smart thermostat can help in maintaining a consistent and comfortable indoor environment by automatically adjusting the temperature and humidity levels based on real-time readings and preset preferences.
