Suction Line Inverted Loop

[Atomg]

I have had lots of internet discussions, but I've never met any ruder people than some on this thread. I've rather come to expect this from HVAC people though. They seem to think selling and installing new equipment is their God given right. Well, I'm here to tell you it's not. I now have two of these systems installed and I'm sure they will they will last a very long time. The installed cost is less than half of what it would have cost if I'd have hired it all out, so it's not a minor deal to someone who doesn't have a lot of money. So you who think you are entitled somehow to do what I can do for myself and charge me for the privilege, drop dead for all I care.

For those that had a helpful word or two thanks and best of luck to you. I'll not be back here ever.

well then...... that will do you a lot of good..... who's rude here.... i believe you were extremely rude....

I dare anyone here to explain the logic in engineering speak why an inverted loop is necessary, helpful or required.

Protects the compressor from oil lugging on start up.

The reason one would use a contractor is to protect oneself from the liability of a catastrophy, also you could be hurt installing it which would probably also void your homeowners insurance. You have mistaken rudeness for brutal honesty, sometimes people don't hear very well when things are sugar coated.

Allows liquid to boil off.

[mark beiser]

The inverted loop helps to prevent the liquid refrigerant, that migrates to/condenses in the evaporator coil in the off cycle, from running down the suction line to the compressor on start-up.
That is the reason pretty much every equipment manufacturer, and piping guide, calls for the inverted loop when the coil is above the outdoor unit.

As has been pointed out, depending on how the piping inside the coil enclosure is piped from the factory, and the orientation of the coil, the suction line may already be routed higher than the rest of the coil before it even leaves the cabinet.
I always rout the refrigerant lines up after exiting the cabinet anyway.

Yep, it does.
