Default High efficiency or not

Lets talk efficiency what through the eyes of a refrigeration person would be considered as high efficiency not the numbers listed by the MFG but what truly would be a reason for high efficiency in a residential A/C unit.

What would be your take on the pic below could it be a high efficiency and why or would it be low efficiency and why.

First off...

What does the manufacturer recommend for clearances?

Where's the pad?

Where's the Emergency shut-off?

Actualy a more efficient way to have said it would have been;

"Neither the first, second, or thrid sentence have anything to do with efficiency"

But seriously, How is one supposed to tell from that photo or any photo what the efficieny is? How do we even know if the plenum coil is properly matched? The current charge? The stated efficiency? etc, etc.

You can tell from down at the end of the next block.

Ok fair enough:

The disconnect was above just out of the pic

The unit is setting on concrete not a heat pump not required to be raised.

Yes the unit was a little close to the exterior wall had a hard time reading the data plate.If it had been moved out any further would of been blocking the sidewalk that traveled back under the raised deck.

Default Re: High efficiency or not

In all seriousness besides the seer rating , the good tech will see if the size of the unit is matched properly to the space it must cool.
To small and it will over work.
Too large and it will burn the compresser with to many starts and stops.
Is the ducting sealed properly.?
Hows the house insulation.?
Are thereturns placed in proper locations and are they balanced to the vents(output)
It is a lot of things.
Me I just turn it on. lol
