Choosing between a Heat Pump and a Central Air System
It’s a key question if you’re looking to get a new air conditioning system: what’s the difference between a heat pump and central air system? Both of them rely on the same basic technology, but they deploy it in different ways, which can has a huge effect on your home. We’re all used to central air conditioning systems, but a heat pump in Maryland makes a lot of sense. Let’s break down the two systems to show you.
Central air conditioning systems use a closed loop system that circulates refrigerant to cool the air. The refrigerant travels through a compressor valve that subjects it to a great deal of heat and pressure, then into a compressor coil that bleeds off the heat into the outside air. This reverts the refrigerant to a liquid state, though it’s still under a lot of pressure. It then moves through an expansion valve and into a series of evaporator coils. As it evaporates, it pulls heat from the surrounding air, cool it. The cool air is then blown with a fan through a system of ducts that distribute it throughout your house.
The heat pump relies on the same basic system, with two key ifferences. First, the closed loop in a heat pump is set up such that it can blow hot air into the home instead of outside. This allows it to function as a heater in the winter and an air conditioner in the summer. Secondly, many heat pumps rely on a ductless mini-split system – distributing multiple units throughout the home instead of distributing the air through ducts. Heat pumps are more efficient than central AC, though they struggle a bit when the weather gets particularly cold and they cost more to install.
