What the heck?? (HP line set sizing)

Thepprof · 03-10-13, 09:52 AM

I'm still a novice at HVAC and questions keep piling up. Ok I just spent a number of hours reading about sizing of the line sets on a heat pump.. why? My 5 systems heat as much as they cool so this reverses all of the velocities etc. that I have been reading about. Common sense in this event tells me that since the lines are used for the most part equally for heating as well as cooling that the lines should be the same size. Any thoughts out there???
