An hvac contractor installed a 5kw heat kit in my heat pump packaged unit. The heat pump works and the ac unit works. However, when I kick the heat to Emergency heat, the air doesnt seem to get hot or even warm. It comes out at about 71 degrees when the temp outside is about the same. The contractor told me that 5kw was not much and I wouldnt feel it unless it was cool outside. This doesnt set well with me. In heat pump mode I get heat, but in Emergency mode it doesnt get warm to me, but I do smell something burning, like a dryer element at first. He told me if I smell it its on. Any feed back??
