Our HVAC guy installed a Geostar unit for our geothermal system. We have never heard of this brand. Does anyone else have one of these and should we be concerned?
The time to have raised this question was before you signed the contract!
As long as your system is well designed and installed with best practices you should get good service from this unit.
Geothermal is an interesting concept...I didn't research it as an option to my split system.
