Heat PumpsHow can Heat Pumps Both Heat and Cool?

Homeowners today face no shortage of options when it comes to ways in which to heat and cool their homes. Many a savvy homeowner has taken notice of the fact, though, that there are now systems which allow them to do both using the same equipment throughout the year. If this sounds too good to be true, trust us when we tell you that the goal is well within your reach. You simply need to use a heat pump in Carnation in order to do so. Schedule your heat pump services with G&S Heating, Cooling & Electrical, Inc. to ensure that your system is able to heat and cool your home effectively and efficiently for year round comfort.

If you are not familiar with the technology, then you may be wondering how it is that a heat pump can both heat and cool your home. The key to this versatility is the reversing valve. True to its name, the reversing valve employed by a heat pump allows for the reversal of its operation and primary function.

Heat pumps use an outdoor coil in their operation. When running in the heating mode, a heat pump uses this coil to function as an evaporator, meaning that it absorbs heat. The coil indoors, meanwhile, releases heat; it acts as a condenser. Liquid refrigerant goes into the outdoor coil, picking up heat, and vaporizes. This vapor enters the compressor, where it is compressed. This allows it to attain a high temperature and pressure, at which point it then travels to the indoor coil. The heat is released, and the refrigerant becomes liquid again. Now the cycle simply starts anew.

By reversing the flow of the refrigerant, the entire function of the heat pump is reversed. The functions of the coil mirror their operations in heating mode, with the indoor coil acting as an evaporator and the outdoor coil acting as the condenser. Heat is absorbed indoors, and the refrigerant is pumped outside. Because the air around the coil is cooler than the refrigerant therein, the heat transfers to the air outside.

If all of this sounds simple, trust us: it is only simple in theory. The only way in which you can count on your heat pump to both heat and cool your home effectively is to schedule your heat pump services in Carnation with a trained professional.
