Heat pumps not only work as a way to heat your home but can also be used to cool down your home. While the heat pump AC unit will pull the heat from the outdoor air and transfer it into the house when the temperature drops, it can also reverse the process and move the warm air inside the home outside. Therefore, a heat pump with AC can be used to cool your house. However, their efficiency may not be as good as central air conditioning systems in areas where temperatures can go incredibly high. Depending on your situation, a heat pump with AC could be a viable solution.
