Hello HVAC Team
I have narrowed down my contractors to 3 for my new heat pump install. These three are the ones that quoted they will install new refrigerant lines.
One contractor quoted " he highly recommends relocating the outdoor unit to the location of the oil tank and removing the refrigerant lineset from the underground conduit. The reason for this is a typical reduction in performance of up to ½% per foot of lineset that is underground! This can increase drastically if the conduit fills with water.
I live on a 50' high knoll of glacial till, so there is absolutely no chance of the conduit filling with water.
I believe this statement is no more than an excuse to not re-run my refigerant lines through my underground conduit?
Any thoughts on the performance/efficiency loss quoted will be greatly appreciated.
