Rowhouse: ducted minisplit system or conventional system?

jberks | Posted in Mechanicals on

I’ve spent a lot of time trying to design a low velocity forced air and zoned ducted system with the main goal of not having vertical chases and bulkheads. Interior design an aesthetics are my main concern here. This is proving to be extremely difficult in a reno like this.

I’m considering the option of ducted minisplit units on each floor While concealing the short runs of duct work within the floor joists on the specific floor. I contacted Mitsubishi and am trying to get some sort of rep to talk to me about options.

However, I have concerns about performance. Like not being able to integrate an ERV, or better air quality measures like a UV filter.

Does anyone have experience with these kinds of builds? Any advice would be appreciated.

    Jamie,
    Are you a homeowner? Architect? Engineer?

    If you feel that you are in over your head, it might be time to hire a mechanical engineer who is experienced at designing residential systems using ducted minisplits.

    Fujitsu's mini-duct cassettes have more air handler power than Mitsubishi's, and can push more air through a longer/ narrower duct. If those duct runs need to go any distance at all you might consider getting a consult with a Fujitsu person too.
