What's wrong with this A/C install? Nothing.

One thing doesn't sit too well with me. If you look at the nearer unit and how the Refrigeration pipes seem to just slope down to the unit. I've installed a heap of A/C gear and a pipe run like that would not usually be done here. Mainly because without any sort of mechanical relief, such as a bend or two, the sound from the unit (50-60Hz hum) will be transmitted to the wall. I've seen this happen before over here.

Ah Reno, I am just weather rubbing it in for all you winter guys. Actually it isn't all sunny here all the time. Right now we are pretty much under water so I should have not bragged.

By renosteinke On this $1.5 million house, with over 100 receptcles....there is no receptacle fir servicing the equipment So what do I win? Look at the second response to this thread. By iwire I don't see any issues unless there is no outlet within 25' by renosteinke The two condensers are separated because they connect to two entirely different systems, located in different part of the house. One in the garage (the near one), and one in the finished basement. This way, the refrigerant lines are as short as possible. This is still no excuse, it is done simply to save money. The mechanical contractor could have grouped these units, they can run the lines as far as they are willing to pay for. Sometimes this means running larger diameter lines due to the distance just like we have to deal with voltage drop. I also agree with shockme, I would have placed the disconnects much lower to hide them better, this is not the side of a factory its someones house. Bob

I agree with ShockMe too... for $1,500,000 those discos could be a little lower. Other than perhaps electricians, they shouldn't be focal points like wall art.
But if they did have to be installed at that height for some reason (though what reason I'd love to know), at least go down the wall with pipe, then a short lenth of flex to the condenser. The way it is now looks very "DIYerish" though likely not a code violation.

The problem here has been identified as the lack of outside gfi outlet by the OP. None of us could really tell that because we cant see around the corner to the right of the closest unit. Might have been a gfi right there and it looks like about 20 feet to the other compresssor to me.

I didn't mean to be unfair, Mac. My main point with this thread was to show the need to know something about other trades.
Several times, I have seen pics like the first one in the trade press, followed by the assertion that, since there is no conduit for the T-stat wire, it must be in with the power conductors. It is then asserted that doing so is aviolation of the NEC- mixing of control and power circuits.
Without getting into a discussion of wheter the thermostst wire is a power limited circuit (to which that rule wuold apply), I wanted to show that the assumption behind those trade-press pics was wrong.
Indeed, some systems don't even have a control wire to the condenser.
We have to work with other trades all the time- and we can do that better if we have a basic understanding of their trade!

Reno, I agree totaly with that. I work with AC contractors all the time as a sub, and love to ask about the workings of the big chillers, package units, and various other stuff installed. Some of it gets pretty complex and hard to understand. At least for me. They have an equally cool trade. No pun intended.

From Alan Belson: This is how I installed my A/c, on a pair of wrought-iron brackets made from old hand forged barn-door hinges, 2" x 3/8" section. This keeps them up off the deck in case of snow. There is no requirement in France for external disconnects. I ducted each 'split' through its own 2.5" PVC pipe, separate condense hose. French technician came today to 'gas up' and fit the copper exp/comp. tubes for me- can't do this gas myself, the pressure is too high [ R410A], special cone tools are required and the gas is 'weighed' in rather than pressure gauged. Eagle eyes may note he has has slightly dented the casing, LH front. Optical illusion, but the unit has 5" clearance at rear. The rocks are granite from Mrs B's "door mining" exploits, we put them there to stop our loony mail man-from crashing his van into the unit. Interior units are on 5/8" birch-ply mounts, as far as I've got with the sheetrock, all on Douglas Fir studs, 8" of glassfibre quilt to go in now.

Looks like what we call here in the states a mini-split system. High voltage to the condensor, control wiring to the remote unit. I've done a few of those.
