    Condensers do great in 150 degrees

    I saw this today. Went to a call on a W/I freezer. 2 of 3 condensers in the attic. Today was a cooler day so it was only about 120 in the attic. But it gets over 150 regularly in attics in the summer where i live. When you add the heat from the equipment, well lets just say these compressors are going to have short lives!

    No way could that freezer keep temp with that ambient

    Unless it was way oversize

    On the plus side the hot water tank is happy

    Wow, that's wild.

    I see stuff like that here and there when it is wide open to a warehouse with a lot of breathing room. Not fully trapped in an attic as it looks in the pic.
    If it is working somehow, I would not want their electric bill.

    Do your customer a huge favor and move them outside. They look like outdoor units. Like maybe Heatcraft or Larkin.

    Can you imagine the compression ratio on them ?

    Look at all the code violations in that install for the water heater

    bet they are just out of the picture, at the wall.

    does that really matter, I have seen it in either up or down in mfr photos?

    expansions tanks can be installed in any direction
    more importantly they need to be installed on the cold water line that one looks like its on the hot side of the tank
    to many times i see them hanging in a manner that when they go bad the weight of them is going to snap the pipe
    use a 3/4 tap tee and stand it straight up so the pipe supports the weight or use a 6 inch brass nipple and elbow coming out of the tap tee and stand it up

    one other thing i find most people miss thermal expansions tanks only come with between 30 and 40 pounds of pressure in them due to shipping reasons you need to charge the tank with a compressor to match street pressure if u dont the tank diaphragm is already expanded before the hot water heater builds pressure

    That is a roof overhead. The next support is just to the left of the picture. Not sure how they got away with it during inspection. The building is only a few years old. The call was up in the mountains, maybe it never got inspected?

    I see what your saying. Looks like about a 3-4 foot span on that OSB
