What is the difference between a heat pump and central air?

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 Franklin or similar Tennessee towns 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 entire house.

The heat pump relies on the same basic system, with two key differences. 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.


When the central air conditioner is heating, it is hot air. The heat is concentrated in the middle and upper part of the human body, and the feet do not feel the warmth at all. The heating end of the air energy heat pump is underfloor heating. The floor is heated first. The feet that warm the person first will not produce a hot air feeling, and will not cause indoor dust accumulation, which is comfortable and healthy. When cooling, the air energy heat pump is a water cycle, and the air temperature is higher, which will not cause the room to dry.

2.energy-saving effect 

The air energy heat pump only needs a small amount of electrical energy to drive, and mainly absorbs the heat in the air for heating. The average energy efficiency throughout the year is close to about 3.0. Compared with traditional heating equipment, it can save a lot of electricity costs each year.

3.longer life

The service life of central air conditioners does not exceed 10 years, while the service life of air-energy heat pumps is as long as 15 years.
