Mini-Split Systems FAQs

  • How exactly does a ductless mini-split system work?

    A mini-split consists of an outdoor compressor unit and one or more indoor air-handling units, linked by a small conduit carrying power and refrigerant. Because they do not rely on ductwork, they deliver conditioned air directly into the specific room where the indoor unit is mounted.

  • Are mini-splits capable of both heating and cooling?

    Yes. The Mitsubishi and AC Pro systems we install utilize advanced heat pump technology. They can reverse their operation to provide powerful, energy-efficient heating during the winter and robust cooling during the summer.

  • How long does it take to install a mini-split system?

    Because there is no ductwork to fabricate or install, a basic single-zone mini-split can often be installed in a single day. Multi-zone systems connected to several rooms will take slightly longer, but the process is far less invasive than installing central air.

  • Can I run multiple indoor units off a single outdoor compressor?

    Absolutely. This is called a multi-zone configuration. Depending on the brand and model, a single outdoor unit can support up to eight indoor units, each with its own independent thermostat control.

  • Are ductless mini-splits noisy?

    No, they are incredibly quiet. Because the noisy compressor is located outside, and the indoor units utilize variable-speed fans, they often operate at whisper-quiet sound levels that you will barely notice.

  • Do I need a permit to install a mini-split in Glendale or Burbank?

    Yes. The installation of new HVAC equipment requires city permitting to ensure electrical and structural safety. As a licensed contractor (License #1135530), we handle all the necessary permitting and code compliance for you.
