Heat pumps/Ac

[Rowdyrick]

I have a 09 knight with Carrier ac/heat pumps I noticed this trip I have condensation coming off the roof when the front heat pump is on just like when the AC is on is this normal ? We have used it more then normal this trip and it working great keeping everything warm inside but I have never noticed the condensation before probably just me but I thought I would ask

YES.  in the Heat Pump mode, it “freezes up” as in ice forms.  My Residential’s do the same.  There is a temperature sensor and the ice melts.  Melting ice runs off, just like condensation.  SO…you get water…either way.  Typically, in cooling, it is a constant flow.  In HP, it cycles….

Great question….in the “middle south”, a AC/HP unit is common.  In the frozen climes of the upper US and the sweltering climes of the deep south and SW, MAYBE not so.  So, how a HP works and not having one at home does raise this question.

GOOGLE or YOUTUBE it…if you need more technical information.

Thanks Tom

In AC mode condensation drips off the evaporator coil. In heating mode, it drips off the condenser coil.
