Central AC floor vents vs mini splits
We’re adding A/C to the first floor of a home we recently purchased. The second floor already has central air, but the first floor does not. We’ve been told it’s not feasible to run new ceiling ducts, so our two options are:
- Central air with floor vents
- Mini splits
The first floor is large and very open concept. We would need 3-4 mini split units if we go that route.
We currently have mini splits in our townhouse, and I haven’t loved the experience. I find myself constantly adjusting the temperature, fan speed, and turning them on and off. I also don’t like sitting directly in front of them, and it seems like the room cools unevenly.
On the other hand, I’ve been told that floor supply vents aren’t ideal for cooling because cold air naturally settles, so they may struggle to cool the entire space effectively.
Ignoring cost, which option would you choose and why? If you’ve had central A/C supplied through floor vents, I’d especially love to hear about your real-world experience and whether it cools the space well.
