How does a Heat Pump Work and what are Its Pros and Cons?

Similar to the conventional heat pumps, ductless mini splits connect with an indoor unit to an outdoor unit. But unlike a heat pump the indoor unit is installed directly into the room instead of doing the extra ductwork system to transfer the conditioned air into the rooms. While furnaces may generate heat, heat pumps use the current heat energy found in the air with the help of refrigerant. You may think how heat pump can offer heat when it is cold out. A conventional AC unit works by getting rid of heat from the indoor spaces and taking the heat outdoors to the condenser unit. A heat pump reverses the process to remove the heat from the external environment and transfer the heat indoors. This works same like an AC unit using cold refrigerant to absorb heat from the external environment.

If the refrigerant is colder than the external air, then the heat can be absorbed as the heat naturally flows from a warmer to a colder body. A heat pump can even absorb heat in extremely cold temperature. If it is still cold outside, the heat pump works harder. Many people with heat pump systems have complaints when heating home when temperature drop below freezing. In such cases, you may need a backup heating system available at The Heat Pump Store in Oregon.
