What Is A Heat Pump And How Does It Work?

Heat pumps are a better and more energy-efficient alternative to conventional heating systems and can effectively maintain a comfortable indoor temperature. Improper heat pump maintenance can lead to frequent heating repairs. For superior service of heating repair in Pico Rivera, CA, contact Hybrid Air Conditioning & Heating.

What is a Heat Pump?

A heat pump is often installed outside of a home and acts as both, i.e., a heating and cooling system. They use electricity to transport heat from one location to another, causing formerly warm areas to become cooler and vice versa.

Components of a Heat Pump.

The outdoor unit comprises a split-system air conditioning system. The indoor air handler unit is the second essential component of a traditional heat pump system. The interior and exterior units feature several essential auxiliary components.

Outdoor Unit

Both a coil and a fan are present in the external device. The coil is a condenser in the cooling mode, whereas it is an evaporator in the heating mode. The fan facilitates heat transfer by forcing air from the surrounding environment over the coil.


The inside unit, or the air handler unit, contains a coil and a fan. When the cooling mode is active, the coil functions as an evaporator; otherwise, it functions as a condenser. The fan moves air through the coil and throughout the home’s ducting.


The heat pump system’s refrigerant component is responsible for absorbing and releasing heat as it passes through the system.


The compressor is responsible for boosting the refrigerant’s pressure and evenly dispersing it throughout the system. For a thorough check of your compressor during heater installation, consider hiring a professional. Contact Hybrid Air Conditioning & Heating for premium services in Pico Rivera, CA.

Reversing Valve

The component of a heat pump system is responsible for reversing the refrigerant flow, allowing the system to switch between heating and cooling modes.

Expansion Valve

By regulating the refrigerant flow as it flows through the system, the expansion valve functions as a metering device to decrease the pressure and temperature of the refrigerant.

How Does the Heat Pump Work?

Heat offers an incredibly advantageous characteristic when it comes to keeping a suitable temperature in our homes and places of business. It naturally fluctuates between high and low temperatures. The heat pump reverses this process by using simple procedures to extract outdoor air, warm it, and introduce it into your home.

On the exterior of an air source heat pump is a set of refrigerant-filled coils coupled to an impeller or fan that draws air from the surrounding environment over them. The liquid within the refrigerant coils absorbs all of the heat and consequently begins to evaporate as it warms up. The gas passes through a compressor, which raises its temperature to a very high level.

The heat is eventually released from particular inner coils within the building. In the interim, the refrigerant returns outside, where it is subjected to a temperature increase before the cycle is repeated. The useful heat is piped through air ducts so that it is distributed throughout the facility. Alternately, the beneficial heat is used to heat the water that circulates through radiators.


It is essential to know certain components or important parts of the system. Along with this, homeowners should also know how the system, i.e., the heat pump works. With better services, regular inspections, you can improve the efficiency and increase the age of your system.
