Well unfortunately I think I’m going to need to install a mini split AC unit in the fish room. It’s been one of those periods of the year in Austin where it’s not cold enough outside to make the house cool, but not warm enough for the central AC to run.
I insulated the fish room pretty well, so when the ambient temperature isn’t cold enough and there’s no air being pushed through the AC vent, heat is building up pretty well in there. I walked in this morning and it was a balmy 84 just from the few pieces of auxiliary equipment and the dehumidifier running. I’m thinking if it’s this warm when it’s in the mid 60s outside, what’s it going to be like when the garage temperature is reaching triple digits?
It might be different in the middle of summer when the AC is running most of the day and pushing cool air into the room, but I’m wondering if it’ll be enough once all the equipment is in there and running 24/7. Also I don’t want these temperature spikes in the spring and fall when the house temperature is in this limbo. Probably better off just biting the bullet now and installing a unit.
I wonder about putting a window unit in a wall and venting the heat into the garage, but that bothers me. I feel like the unit won’t be efficient that way and will just burn itself out when it only has a garage to dump heat into. A mini split will require more money and work, but probably the best solution here.
