There are two things about heat pumps that make them absolutely amazing. The first is their efficiency, especially when it comes to heating. Since they only transfer heat rather than having to generate it, they use less energy in comparison to other heating systems such as furnaces.
The second is their ability to function both as heating systems and as air conditioners. But when that ability is compromised, it can cause incredible frustration. What good is this amazing system when it can’t do the jobs it’s designed to do? If your heat pump won’t switch modes, there’s one component which is responsible: the reversing valve.
