I wonder if it would be efficient if a split AC's outdoor unit is installed 8 feet underground in a well with ventilation will be any efficient due to the constant temperature underground all year round?

  • \$\begingroup\$ no, the unit is not water proof, but should I worry if its just 8 feet underground with enough ventilation? \$\endgroup\$ – Sohail Jan 16 '18 at 11:37

In my opinion that's an interesting sollution. And it should work better.

working model

The problem I see is if your AC unit is strong enough. I mean that you should check the strength of air flow from the AC to the compressor.

However if you are only talking about efficency ONLY than it should work better.

In the diagram you can't see but ambient temperature for outside tubes is also important and it affects the system, however as I told previously, the problem is the airflow strength and the 16 feet distance.
