Frequently Asked Questions About Passive House Air Conditioning


Below we’ve answered some of the most common questions about our Passive House AC services to help you make an informed decision. Got more questions not covered here? Feel free to reach out to us via our contact page. We’re here to help you find the best cooling solutions tailored to your needs.

  • What makes air conditioning for Passive Houses different?

    Passive Houses require air conditioning systems that operate efficiently in airtight and highly insulated environments. These systems are designed to provide consistent indoor comfort while consuming minimal energy, often integrating with HRV or ERV systems.

  • Can I install traditional air conditioning in a Passive House?

    Traditional air conditioning systems are typically not suitable for Passive Houses due to their higher energy consumption and inefficiency in airtight environments. Our specialised Passive House air conditioning systems are designed to meet these unique requirements.

  • How often should a Passive House air conditioning system be serviced?

    We recommend servicing Passive House air conditioning systems at least once a year to maintain efficiency, air quality, and compliance with Passive House standards.

  • Can you retrofit an existing home to Passive House standards with your air conditioning services?

    While retrofitting a home to full Passive House standards is complex, we can upgrade your current air conditioning system to improve energy efficiency and align it with Passive House principles.


  • How much does Passive House air conditioning installation cost?

    Costs vary based on the size of your home, system requirements, and the complexity of the installation. We provide tailored quotes after an initial consultation to assess your specific needs.
