Today I condemned a 2 month new compressor in a Carrier Duct Free heat pump outdoor unit. The system ran out of freon .I've been toying w/ the idea of adding a loss of charge low press safety switch to ALL of my Duct Free/Less systems.Anyone do this? We did not put this system in ,the lawsuits are flying,the fingers are pointing,and the tounges are flapping.I'm glad the fan is way over there!
