6 decades oh my fucking god big difference <| sep |> Low end RB 1 for low end WR 1 . Fair trade <| sep |> How cold is it ? Heat pumps will go into defrost mode if it detects ice forming causing the reversing valve to switch into AC mode . I ' m fairly certain that the compressor has to stopstart when this happens and again when it goes back to heat mode .
