Hello,
I recently was contacted by a home owner in need of a pre-listing home inspection. The one item the home has is a geothermal system. The home was built in 1967, the system was added at a later date,
Can anyone give me any advice on how to inspect a geothermal system?
Turn it on … See if it works … Then explain since these are si infrequently seen and 90% underground recommend a FULL service checkup by a competent hvac contractor versed in geo-thermal systems.
