How should I properly seal the refrigerant lines? It is at ground level. Do I need to wrap anything around the foam insulation on the refrigerant line? Should I just use spray foam? Or Should I use spray foam but place a 1" concrete plug over the end?
My mother had her HVAC unit replaced. There was some sort of issue with the unit and they left some gauges on it, outside. It has been 10 days. Should I be concerned?
