We don’t have central air. Our parlor floor has no windows which accomodate window A/c units. we need to find a solution if we are going to stay in this house- which we will, as summers are hideous on that floor- especially in the kitchen!! People have mentionned these Mitsubishi units installed into the wall(I assume with an access to outdoor…not sure how they work). Is there a massive outdoor unit too? Anyone have experience with these? Cost? effectiveness? where do you find them? Who installs them? etc..
Thanks!
I am having a 3 zone mr slim system installed right now.. The setup I got can have a 4th zone added on.. I have a unit in each of my bedrooms and a bigger one for the first floor..
I can’t say how well it works yet, but after getting multiple quotes for high velocity systems and different configurations of the ductless system, this setup makes the most sense to me..
complete install is running $9k..
I am in philly..
Whirlpool Model ACP102PSO;10,000 BTUs; c.45-50 lbs, around 36X18X12, cost c.$350 two years ago. Quiet, but very effective. Store it in a closet or basement after the summer.
4:54 – what is the brand of your portable A/C, how many BTU’s, and what does it weigh? Thanks.
Seems like an awful lot of work for a few days of summer. We have had great success with a large portable air conditioner for a large room with roof exposure. All it needs to vent is an opening roughly four by six inches; no problem, assuming you have any kind of window. The room has northern exposure, so tough to say how well it would work if yours is full sun.
10:08: Read. Posts. Carefully ;).
Seriously, tho’, you have one air-handling unit in front room, one in back, running off the same external compressor unit. More internal units are possible if you have capacity in external. These are called multi-zone systems, and, while more expensive than single-zone, each unit can be independently operated so you save not cooling parts you don’t want to.
5:07 here.
“Can you run several internal units off the same external part?”
Yes. Check out the catalog. They have different types, including heating/cooling ones, different interior unit styles, etc. Some are multi-zone, but they are more expensive. Alternatively, you could just get two (though installation and electrical would be more.)
As far as mounting it on the roof goes, I confess to not knowing the fire code back and forth, but I do believe some arrangement could be worked out. I discussed mounting my current Mr. Slim on the roof above my kitchen, and Rumba never indicated it would be a problem. (Mitsubishi makes a plastic mounting mat for it to put on your roof, I believe…) The way they did it, they fabricated a metal bracket out of angle iron and installed that into the exterior wall through the capstone stuff, so it is actually just above the roof. You could easily have that done on the top floor of your house, and I bet it would cool most of not all of the house, particularly if its a tall and narrow brownstone.
As far as the question about being 50 feet deep, you probably couldn’t/wouldn’t want to place the exterior unit that far from the interior one, but why would you have to? You could run it 25 feet for sure, and thus have the essentially in the middle of your house even if you had to mount it on the back wall. Remember the interior unit has to drain somewhere though.
I can’t see how having one ac unit/floor works for most brownstones. Maybe I’m missing something here. On the parlor floor I get how a unit in the back could cool the whole double parlor. On the upper floors, how is a unit in the back room going to cool the front of the building? Through the pass-through closets?
There’s typically a limit on the distance, and, frankly, you probably want to be well under it, as efficiency suffers with length. But if your unit is mounted at the back, and the inner unit is at the back of the front parlor, it should be about 30′, not 50′. You have to include the vertical length if the outer unit is not at the same height as the inner ones.
Does it mean that you are out of luck if your brownstone is more then 50 feet deep?
