    This unit was installed in a new house late 2014. Pressurized with horizontal ground loop. The Barron techs are still here diagnosing with the latest comment being compressor overheating. When they first came out last week a leak was suspected, but nothing had been done to the unit since Summer 2020. Would have to be a pretty slow leak.
