The true benefit of a heat pump is that it provides both heating and cooling: all the work of two major appliances in a single system. Of course, there are other benefits, notably the extreme efficiency with which a heat pump heats. But you’re really not getting what you signed up for, and what you deserve, if the heat pump doesn’t both heat and cool.
So what is going on if your heat pump gets stuck in one mode? There’s really one mechanism responsible for switching the heat pump from one mode to another, and three parts of it which could be causing your problem right now.

Heat pumps work as both heaters and air conditioners in one, using the principles of air conditioning to both cool your home in the summer and heat your home in the winter. Heat pumps are economical and effective, and recent advances have made them a better option than ever. But like any other appliance, heat pumps run into trouble from time to time, and when they do, you need to get them addressed quickly. With 
Spring is the season when homeowners get rid of their old air conditioners and install a new one. It makes sense to do so now, especially if your old system is at the end of its run. Better to install a new one now and enjoy the benefits of improved efficiency and performance
