My ac unit will blow freezing cold air 24/7 and then once a day, usually around 2-4pm it will blow warm air for about 20 minutes.Is this a common thing?The unit gets serviced regularly and is kept clean. It's done this for as long as I remember but I usually only notice if I fall asleep on the sofa and it happens, making the room unbearably warm. via /r/DIY http://ift.tt/2j76rFd
