[quote=Clifford][quote=ltsdd]I got two units, a 3 and a 4 ton 13 seer R-22, installed by one of the companies the OP mentioned for $6K even. The house was pre-plumbed. I picked one of the cheaper brands that they carried. The coil runs a bit noisy, but when the ac is running I have no business being outside so that has no effect on me. As for the efficiency, I didn’t think I would use it enough to justify paying for a more efficient one.
BTW., I would seriously consider the wall-mount single room ac if I didn’t already have central ac. I think the single room ac is much more energy efficient – cool the room you’re in and not the entire floor.
You had duel ACs, right ? How old were the AC units when you replace them ?
Did you replace the furnace also ?[/quote]
The house was bought pre-plumbed for AC but I didn’t have AC installed until about 7-8 years ago.
I think they’re dual ACs – two separate coils/fans outside, two separate copper lines feed into two separate condensors(?) that they installed in the attic. Two thermostats, one for each floor.
