AC Condensor Location - This is a new one for me

Older house with pool. AC condensing unit located about 60' from home with line set and electrical buried under ground. Thoughts?

I had the same question sometime ago.

If I am not mistaken it is around 25 feet max before efficiency starts dropping of drastically/ Could be wrong

I think that might be true with a heatpump in the heating mode, but don't see any reason for A/C or heatpump in the cooling mode.

Im not sure why someone would do this other than they dont like the look of a condensor or the noise. I saw plenty of places around the house where they could have put it with minimal visual exposure/noise. I believe the electrical is only ran in the flex (if even that once its underground, hard to say).

At first, I thought I must be imagining things. I walked around the house several times before I finally found it (buried in a bunch of shrubbery). Also not an electrical disconnect in close proximity.

Was the disconnect within sight of the unit?

Where is the shut off ?

No separate shut off, however the main panel was somewhat within the line of sight (if you removed the vegetation around the condensing unit).

Sounds like a judgement call, (IRC 4001.5 Disconnect in sight of equipment). I don't think I would write it up.

For example, here's Carrier's requirements for residential Puron units:

Note line lengths of up to 200 feet (100 feet away), and up to 250 feet equivalent line lengths.
