How to Choose the Right Bulkhead Air Conditioner for Your Space and Budget

Beating the heat is essential for year-round comfort in Australia, and finding the right air conditioning solution can make a difference. While traditional split systems are popular, bulkhead air conditioners offer a unique, space-saving option for specific situations.

What is a Bulkhead Air Conditioner?

Bulkhead air conditioners are compact units designed for discreet installation within a bulkhead – a recessed wall cavity. This placement allows them to blend seamlessly into your existing space, making them ideal for areas with limited floor or wall space.

Benefits of Bulkhead Air Conditioners

Bulkhead air conditioners offer several advantages over traditional split systems:

  • Space-saving: As mentioned earlier, their ability to be installed within a bulkhead makes them perfect for smaller rooms or areas with premium floor space.
  • Discreet design: Because they’re recessed within the bulkhead, bulkhead air conditioners maintain a clean and uncluttered aesthetic.
  • Directed airflow: Bulkhead air conditioners often direct cool air downwards, creating a comfortable cooling zone directly beneath the unit.
  • Quieter operation: Due to their placement within the bulkhead, some bulkhead air conditioners boast quieter operation than traditional split systems.

Things to Consider When Choosing a Bulkhead Air Conditioner

While bulkhead air conditioners offer many benefits, it’s essential to consider several factors before making a purchase:

  • Space requirements: While they’re designed for bulkheads, ensure your bulkhead cavity has the necessary dimensions to accommodate the chosen unit.
  • Cooling capacity: Bulkhead air conditioners typically have a lower cooling capacity than traditional split systems. Carefully assess the size of the space you want to cool to ensure the unit can handle the load.
  • Airflow direction: Consider the desired airflow direction. Some bulkhead air conditioners direct air downwards, while others offer multi-directional options.
  • Noise level: Research the unit’s noise output, especially if intended for a bedroom or quiet area.
  • Installation: Bulkhead air conditioners typically require professional installation within a bulkhead. Factor these installation costs when budgeting for your new unit.
  • Maintenance: Regular cleaning and filter maintenance are crucial for optimal performance and longevity of any air conditioner. Ensure the chosen bulkhead air conditioner allows easy cleaning and filter replacement access.

Choosing the Right Size Bulkhead Air Conditioner

Selecting the right size bulkhead air conditioner is essential for effective cooling. An undersized unit will struggle to maintain a comfortable temperature. In contrast, an oversized unit will be inefficient, leading to higher energy bills.

Room size is a significant factor, but other considerations include:

  • Ceiling height: Higher ceilings may require a more powerful unit to ensure proper air circulation.
  • Insulation: Homes with good insulation will require less cooling power than poorly insulated spaces.
  • Sun exposure: Rooms with significant direct sunlight will generate more heat and may require a larger unit.
  • Number of occupants: The number of people using the space will influence the heat generated.

It’s recommended to consult with an HVAC professional to determine the exact cooling capacity (measured in kilowatts or BTU) required for your specific space.

Additional Features to Consider

Once you’ve narrowed down your options based on size and essential features, consider these additional functionalities that may enhance your comfort:

  • Variable speed inverter technology allows the unit to adjust its cooling power based on demand, resulting in quieter operation and improved energy efficiency.
  • Remote control: A remote control allows for convenient operation from a distance.
  • Sleep mode: A sleep mode feature can adjust settings for quieter and more energy-efficient operation during sleep hours.
  • Self-cleaning function: Some bulkhead air conditioners offer a self-cleaning function that helps to reduce dust build-up and maintain optimal performance.


Bulkhead air conditioners can be a stylish and space-saving solution for cooling specific areas in your home or office. Considering the above mentioned factors and consulting with an HVAC professional, you can choose the right bulkhead air conditioner to meet your needs and budget, ensuring cool and comfortable living throughout the year.
