Types of Heat Pumps

Different types of heat pumps vary in terms of noise levels – from quiet to very loud. Depending on the model and make of a heat pump, the noise produced can range from a light humming to a loud whirring.

Some of the most popular heat pumps come in both ducted and ductless systems, and it’s important to know what type of system works best for your home.

In this section, we’ll look at the different types of heat pumps and discuss the noise levels they produce.

Air Source Heat Pumps

An air source heat pump (ASHP) is a type of energy efficient heating and cooling system that uses heat from the air in your home to warm it up in winter or cool it down in summer, using less energy than traditional heating and cooling systems.

Most ASHPs use an electric fan to draw air through an evaporator coil where refrigerant absorbs the heat, which is then sent via a compressor outside to either heat up or cool down the home’s interior.

Unlike furnace-based systems, ASHPs are quieter and require little maintenance, though they may still be considered loud from time to time due to the electric fan that is constantly running.

Many of the newer models feature technology designed for improved energy efficiency and sound-dampening materials that make them much quieter than traditional furnace-based systems, producing decibel levels comparable to quiet conversation.

The two main types of ASHPs include ducted and ductless mini-split systems. Ducted models are designed for use with existing ductwork while mini-split systems require no ductwork at all.

While both types can provide efficient heating and cooling when properly sized for your home, factor in noise levels when selecting different brands as several manufacturers offer technologies specifically intended for quiet operation.

Geothermal Heat Pumps

Geothermal heat pumps are an efficient and reliable way of keeping your home comfortable. A geothermal heat pump can reduce the amount of energy consumption in your home by as much as 70%, making them a great choice for homeowners looking to save money and lower energy costs in the long run.

Geothermal heat pumps provide highly efficient all-year-round comfort by using the thermal energy stored deep underground via a ground loop system.

These systems do not depend on traditional sources of fuel, such as gas or electricity, but instead use a renewable energy source, which means they are both environmentally friendly and cost-effective.

In addition to their environmental benefits and cost savings, geothermal heat pumps are also known for being some of the quietest types of heat pumps available.

This is due to their insulated casing, which helps minimize noise transfer from inside the unit to the outside environment. Furthermore, these systems require no outdoor condenser since they don’t involve burning fuel or creating an ignition source — making them notably quieter than traditional forced-air systems that involve gas furnaces or electric heating coils.

Overall, geothermal heat pumps are one of the most energy-efficient ways to maintain consistent temperatures year-round without producing loud noises or releasing pollutants into your community’s outdoor air quality.

They can produce sufficient levels of warmth during winter months while cooling air effectively during summer months — giving you comfort and peace of mind at all times!

Ground-Source Heat Pumps

Ground source heat pumps are a form of renewable energy technology that utilizes natural energy from the ground to heat and cool buildings.

It works by collecting energy from the ground through a series of pipes – known as a ‘ground loop’ – which are buried in the ground. This energy is then used to heat the building, either directly or indirectly, and can also be used to cool the building in the summer.

Ground source heat pumps are increasingly being seen as an efficient and cost-effective way of heating and cooling buildings, making them a great choice for those looking for a more sustainable way to heat and cool their homes.

Noise Levels of Heat Pumps

When considering buying a heat pump, a common concern is how much noise the unit will make. As heat pumps are used to heat and cool homes, its important to consider the noise levels of various different heat pumps.

In this article, we’ll be exploring the noise levels of different types of heat pumps and highlighting which one is the quietest.

Air Source Heat Pump Noise Levels

All heat pumps generate noise, from loud to very quiet depending on the manufacturer and the size of the unit. Air source heat pumps are generally noisier than ground source heat pumps because they are external and located outside your home.

However, advances in technology in recent years have made it possible for air source heat pumps to produce noise levels as low as 40dB(A), which is equivalent to the sound of a low-volume conversation occurring inside a room.

Modern air source heat pump systems have enhanced insulation within their casing, as well as more efficient motors, thus reducing noise emitted both during operation and standing still.

Additionally, most modern air source heat pump systems come with an acoustic hood that dampens the sound produced while they’re running.

These technological advancements means that manufacturers have been able to reduce sound output by UP TO 30% over their earlier units meaning a much lower noise level both externally and into the property itself.

To decide what type of model you should choose, start by researching different brands and models available on the market today.

When researching a particular model or brand, it’s important to check for verified product reviews or contact one of our specialists for assistance in selecting a flame-free option or battery model that meets your needs precisely.

Geothermal Heat Pump Noise Levels

A heat pump is a form of HVAC system used to move heat into or out of an area. They are often used to control temperature and humidity levels in residential and commercial areas. Heat pumps are usually classified as either air source, water source, or geothermal based on their sources of energy.

The noise generated by different types of heat pumps can vary significantly due to the materials used in their construction, the type of motor driving them, and other factors.

Geothermal heat pumps have the lowest noise levels due to the nature of the power source and the advanced methods used for sealing and insulating them. Many geothermal systems produce sound control levels below 35 decibels at distances up to 20 meters from the appliance – making it one of the quietest electric heating sources available.

In comparison, traditional air-source electric or gas units generally operate between 40-50 decibels at similar distances with some high end models producing lower sound pressure figures.

Noise levels for water source systems increase relative to how far they are away from bodies/sources of water as these can also act as a dampening mechanism that helps reduce noise pollution further away from the system..

Both geothermal and air-source heat pumps offer advantages over water-source models when it comes to noise pollution, providing a quieter heating solution to homeowners who want peaceful temperatures within their homes without disruption from loud equipment operating outside.

Ground-Source Heat Pumps Noise Levels

Ground-source heat pumps are generally very quiet, especially when compared to other heating and cooling systems. In fact, they usually make less noise than a standard refrigerator.

Most ground-source heat pumps operate at a sound level of around 45 decibels, which is about the same as a quiet conversation between two people.

This makes ground-source heat pumps perfect for use in homes and businesses where noise levels need to be kept to a minimum.

Factors That Affect Heat Pump Noise

Heat pumps can be unusual sources of noise, and the level of noise in your heat pump can vary greatly depending on a number of factors.

From the size and placement of the heat pump to the type of refrigerant used, there are a number of things that can influence the noise level of your heat pump.

Let’s take a look at some of the factors and how they affect the noise level.

Age of the Heat Pump

The age of the heat pump can alter the amount of noise it produces. If your heat pump is older, it’s likely going to be noisier than newer models.

Newer heat pumps are designed to be quieter during operation and this is due to advances in technology. The sound dampening materials used in newer models will help reduce the amount of noise that your heat pump makes, allowing for a quieter environment.

Additionally, replacing key components such as fan blades and motors with upgraded versions can significantly reduce the noise made by older heat pumps.

Installation Quality

The quality of the installation of your heat pump can have a huge impact on the amount of noise you hear. Poor installations are more likely to cause operational issues or fail sooner than correctly installed systems.

This is because things like incorrect bends and sizing in the ductwork will create turbulence that can cause loud rattling and vibrations, making your heat pump sound noisy.

Additionally, any non-HVAC contractor performing heating and cooling services may not be aware of the exact requirements for an efficient, quiet system.

It’s best to hire a licensed HVAC professional for all of your heat pump installation needs to ensure that it’s done right the first time.


In order to keep the heat pump running quietly, users must properly maintain the unit on a regular basis. As with any mechanical system, moving parts require lubrication in order to reduce friction and noise.

Additionally, regularly checking the condensers and evaporators for any dirt and debris buildup and cleaning these components can help reduce overall noise levels as this buildup can interfere with fan motors.

Checking for any loose components or connections and tightening them is also important in reducing vibration from parts and heat pump noise.

Regularly checking the refrigerant levels of a heat pump is essential to ensuring that it works at peak efficiency since low refrigerant pressures can cause motors to work harder which results in higher amounts of noise.

Lastly, making sure that all filters are cleaned or replaced on cue helps since clearer air flow reduces fan load on motors resulting in less noise output from the system.


In conclusion, all heat pumps will inevitably create some noise as a result of external factors such as wind and rain, as well as the inner workings of the system.

The key to a quieter heat pump is to ensure that it is properly installed in order to prevent any unnecessary vibrations and to maintain low sound levels throughout its operation.

Fortunately, most newer models of heat pumps have been designed with increased insulation measures and improved technology, meaning they are often much quieter than older models.

The quietest type of heat pump is generally considered to be air-source models due their ability to reduce noise from fan motors and compressors.

Nevertheless, it can be useful to research each device thoroughly in order to determine which one best suits your needs in terms of both price and sound level.

With the right care, attention and maintenance during installation and upkeep, you should be able to enjoy a more peaceful living space with your new heat pump for many years to come.
