Air Rotation (ductless mini-split systems) are commonly used in commercial buildings. Overall, air rotation heating offers a compelling solution for large warehouses and distribution centres. Its efficient and uniform heating, coupled with relatively low installation and maintenance costs, makes it a strong contender when seeking reliable temperature control in these spaces.

Remember to weigh the pros and cons against your specific needs and consult with HVAC professionals for further evaluation and tailored recommendations.


  • Energy efficiency: They avoid ductwork losses, which can be significant in traditional systems, leading to lower energy bills and reduced environmental impact.
  • Flexibility and individual control: Each unit can be controlled independently, allowing for different temperatures in different zones, optimizing comfort and further saving energy.
  • Easy installation and scalability: Installation doesn’t require extensive ductwork, making them easier and faster to install, especially in existing buildings. Additionally, individual units can be added or removed as needed for changing spaces or needs.
  • Space-saving Eliminating ductwork frees up valuable space in your building.
  • Potential for improved air quality: Some models offer air filtration, contributing to cleaner indoor air.


  • Higher initial cost: Compared to replacing just a compressor in a ducted system, the upfront cost of mini-split systems can be higher.
  • Limited heating capacity: Individual units might not be suitable for very large spaces or extreme heating demands.
  • Aesthetic concerns: Multiple indoor units, especially in large numbers, might be visually less appealing than traditional systems.
  • Maintenance considerations: While generally low-maintenance, individual units require more frequent cleaning and filter replacements compared to central systems.
  • Noise: Depending on the model and installation, some units might generate more noise than central systems.
    Ultimately, the suitability of commercial air rotation heating depends on your specific needs and priorities.

    Other factors to consider

  • Building size and layout: Are there different temperature zones needed?
  • Budget: Can you afford the initial investment?
    Existing infrastructure: Is there existing ductwork or space limitations?
  • Heating/cooling demands: How extreme are your heating and cooling needs?
  • Aesthetics: Are the visible units acceptable for your space?
