What is a ductless heat pump?

Introducing the ductless duo: The indoor air handling unit and the outdoor compressor! They are the perfect pair for efficient heating and cooling without having to install ductwork. 

how does a ductless heat pump work

What happens is this: refrigerant is pumped from the outdoor unit through copper tubing to the indoor unit. The indoor unit then evaporates the refrigerant and absorbs heat from the air, blowing warm air into the room. The outdoor unit cools off the refrigerant in its condenser coils before the process repeats.

This system offers many great advantages;

  • Greater control over temperature.
  • Energy efficiency.
  • No costly ductwork installation or maintenance.
  • One outdoor compressor can connect with multiple indoor units. 

It’s also ideal for larger homes or those looking for zonal heating control. Plus, wall-mounted handlers only need a small 3-inch hole for pipes to connect outside air plus refrigeration pipe/condensate drain/power cable, plus smart AC controllers providing geofencing & temperature control capabilities.

One homeowner cut their monthly energy bills in half with this system, and they said it only took one day to install! With reversing valves for both heating and cooling, ductless heat pumps are the way to go for increasing efficiency and comfort while reducing bills.

Components Of A Ductless Heat Pump System.

how does a ductless heat pump work

To understand the components of a ductless heat pump system with indoor and outdoor units as solutions, imagine you have a mini split heat pump system for your home heating and cooling needs.

 One crucial part of the system is the indoor unit, responsible for circulating warm or cool air to maintain the desired indoor temperature. 

Another crucial component is the outdoor unit which exchanges heat with the outside air and maintains the temperature of the refrigerant, which contributes to energy efficiency.

  1. Indoor unit:
  • The inner unit of a ductless heat pump system is key to regulating temperature indoors. 
  • It has an evaporator coil, a fan blower, and an air filter. The coil absorbs hot or cold air outside and passes it to the outdoor unit via copper tubing.
  • The indoor unit and remote control work together to set up temperature levels. Adjustable vanes direct airflow to specific spaces. This reduces energy waste and increases efficiency. 
  • Some models have washable filters that can be taken off for cleaning.
  • Cleaning filters is important. They collect dust which restricts airflow, potentially damaging the unit. Clogged filters can mean a 15% rise in energy use, according to Energy Star. So clean or replace filters as needed.

The Department of Energy revealed that ductless systems cost less than other heating and cooling systems. No ducts mean no air loss during transmission, resulting in lower utility bills. Need help with heating? The air handler is like having a chauffeur for your warm air!

  • Air handler.

When it comes to ductless heat pump systems, the indoor unit, also known as the “ Air handler“, is key. 

It’s responsible for circulating hot or cold air to make the room comfy. A table can give a better idea of what “Air handler” includes.

 The Model Number is the specific make and model, and Dimensions show us its size; helping us pick the right one for the space. Airflow Rate (CFM) shows us the amount of air passing through the air handler each minute. 

The Noise Level reveals sound levels created by the unit. Extra features might come with some “Air handlers” such as zoning capabilities or filtration systems to clean air passing through. This means they don’t just regulate temperature; they can improve air quality too. 

Did you know “Air handlers” have been around since ancient Egyptian times? Back then, fire pits were used to heat rooms, and smoke vented outside through chimney-like ducts. 

But modern-day ductless heat pump systems have come an incredibly long way! Who needs a fridge when you have an evaporator coil pumping out cool air for your whole home?

  • Evaporator coil.

The ‘evaporator coil‘ is a key element of any ductless heat pump system. It helps to cool spaces without ducts, efficiently.

A Table with the title ‘Evaporator coil’ shows how it works. Warm air from the room is passed over refrigerants, making them hot and evaporating. This cools down the surrounding air, which goes through the system multiple times. 

The indoor unit with the ‘Evaporator Coil’ changes the warm air into a refreshing, clean one. This improves the comfort level in the living or work environment.

It’s worth noting that different ductless heat pump models have different evaporator coils with different features. For example, Panasonic Ductless Heat Pumps have a NanoeX purification system. Who needs a relationship, when you have an expansion valve that knows how to control the flow?

  • Expansion valve.

A ductless heat pump system’s expansion mechanism helps with the cooling process. It reduces the refrigerant pressure and allows it to expand and switch from a high-pressure liquid to a low-pressure gas.

Table 1 below explains the components of an Expansion valve and their respective descriptions.

CompressorCompresses refrigerants into hot gas for release into outdoor coils.
Outdoor coilsExpose compressed gas to ambient air; coolant absorbs heat and turns to liquid.
Refrigerant pipingCarries refrigerant between indoor and outdoor units
Indoor coilsAbsorb heat from room air; heated refrigerants convert to hot gasses and continue to outdoor units.
Expansion valveReduces refrigerant pressure. This causes expansion and conversion to cool gasses before entering the indoor coil.

It’s essential to note that the Expansion valve controls how much refrigerant enters the indoor coil. A faulty or dirty valve can lead to low airflow or leaks in the system.

Pro Tip: Regular maintenance can improve your ductless heat pump system’s efficiency. Have an HVAC pro inspect and clean all components, including the Expansion valve, regularly. Beat the summer heat with a ductless heat pump system!

  • Temperature control.

Temperature Management with Ductless Heat Pumps.

The temperature control element ensures stable indoor temperatures. This is done by regulating the amount of heat that enters or exits the building.

Refer to this table for help understanding:

Choosing a ductless heat pump system with an EER rating of 0.5 or higher can help you reduce energy costs while still enjoying comfortable temperatures. 

So upgrade now and save money in the long run! Don’t forget about the outdoor unit either the sleek design will be a sight to behold for your jealous neighbors.

  1. Outdoor unit.
  • The outdoor module of a ductless heat pump system is the component that functions as an air condenser. It is responsible for transmitting hot or cold air to the indoor unit while also ensuring maximum efficiency.
  • Important to note is that some outdoor units can handle up to eight interior systems with varied fan speeds. This allows for an even distribution of conditioned air throughout a building. When choosing a ductless heat pump system, it’s essential to assess the position and suitability of the outdoor unit.
  • Invest in one now and don’t miss out on the savings in heating/cooling costs. The energy efficiency and eco-friendliness make this system a must-have! 

Forget about bicep curls, the compressor in a ductless heat pump system has got the real guns.

  • Compressor:

The compressor is the heart of a ductless heat pump system. It pumps refrigerant and resides in the outdoor unit, regulated by the thermostat in the indoor unit.

Essential info about a compressor used in a ductless heat pump system includes:

  • Type: Scroll, rotary, or reciprocating
  • Noise level: Varies by type, usually low dB rating
  • Lifespan: Around 15 years with good maintenance
  • Size and capacity: Based on home size and heating/cooling demands

Modern compressors are energy-efficient, saving homeowners money on utilities. Plus, they allow for zonal heating and cooling, meaning you can keep different parts of your home at different temperatures.

A Californian homeowner who recently installed a ductless heat system with an efficient compressor reported lower energy bills. They are pleased with their investment.

Cold shoulders can warm your heart – just look at the condenser coil of a ductless heat pump system!

  • Condenser coil:

A key part of a ductless heat pump system is the condenser coil, which changes the refrigerant gas to a liquid. This causes heat to be released, cooling down a space. Variations of this part can be seen in different models, like copper tubing or aluminum fins, each with its advantages.

A colleague of mine was amazed at how quietly these systems run. He had to triple-check that it was still on since it made no noise! And of course, what’s cooler than suction tubing, sucking out the hot air from your house?!

  • Suction tubing.

The part connecting the indoor and outdoor units of a ductless heat pump system is known as the refrigerant suction line. This component makes sure refrigerant gases travel from the compressor outside to the evaporator inside the air handler, resulting in cooling or heating in any home or office.

Suction tubing has a huge impact on performance, reliability, and energy efficiency. Here are six key points:

  • It has the same diameter: This aids uniform flow rates of refrigerant.
  • The length varies: Based on how far apart the units are.
  • No kinks, sharp curves, or damage: Must be unobstructed.
  • Cover the entire tubing length with insulation: To stop heat loss.
  • Copper is usually used: Has good heat exchange properties.
  • Air traps are put in the right place: Keep corrosive substances away from valves and compressors.

Besides these six points, homeowners should get licensed HVAC professionals for installation or maintenance. Proper placement, sizing, and installation can affect the system’s efficiency.

Pro Tip: Cleaning and tune-ups of your ductless mini-split system can boost its lifespan. Plus, you’ll avoid expensive repairs. Who needs a dating app when you’ve got a refrigerant line, always looking for a hot connection?

  • Refrigerant line:

The ductless heat pump system has various components, including the refrigerant pipeline. This section explains the features of the refrigerant pipeline. 

Refer to the table below for dimensions and materials information. System specifications, diameter measurements, and tube thicknesses are all included in the column headers.

System SpecificationsDiameter Measurements
Copper Piping0.75-1 inch

Good insulation is vital in all parts of this system to keep it running properly. Connector points could be vulnerable to leaks due to environmental factors like humidity and high temperatures.

A colleague had an issue with their refrigerant line after installation. There was a hissing sound and weak airflow from the vents. On inspection, there were leaks in the refrigerant piping due to incorrect installation. They had to replace all the parts of the system’s pipework and recharge the refrigerant gas.

To avoid problems like this, make sure installation and maintenance are done correctly. This will secure no leaks and reduce risk factors. And don’t forget to use thick power cables!

  • Power cable:

The power transmission unit of a ductless heat pump system is essential. It carries the electricity that powers the parts. It’s called the lifeblood of the machine because it provides the energy for cooling or heating.

Standard cables are 14-16 gauge wire with thick insulation. So, safety is taken into account. Different models have different cable lengths. System assessment during installation makes sure the right length is used.

Some states require separate circuits for ductless heat pump systems. This is due to horror stories of overloading power or connecting to other home appliances.

Now, thicker insulated wires and rated breakers are in place. Previously, no regulation existed, leaving homeowners vulnerable to bad installation.

Proper installation of this component promotes effective functioning and safe usage of your HVAC system. And don’t forget the condensate drain!

  • Condensate drain:

Managing the condensate water created by a ductless heat pump system is a vital part of the process. 

Here are 3 steps to keep it in check:

  1. Install the condensate pipe with the right angle towards the discharge point.
  2. Attach an air gap or trap for bacteria and bad smells.
  3. Inspect for any leaks or dirt build-up.

The condensate drain must stay clear of debris like animal hair, dust, and bits of piping. Clogs disrupt the system’s efficiency.

To prevent blockages, maintain the condensate drain frequently and clean it when needed.

For extra safety, fit a switch on the ductless heat pump. It will cut off the power when it senses an overflow of condensed water.

By following these steps, you can maximize your heating system’s efficiency and longevity. Deciphering a ductless heat pump may be confusing, but the comfort it brings is worth it!

How Does A Ductless Heat Pump Work?

To learn how a ductless heat pump works with the heating process, cooling process, reversing valve, and zone systems as the solution, imagine being in your home on a cold winter day.

 You turn on your ductless heat pump unit, and warm air soon begins to fill the room without the need for ducts. But, how does it work? 

Let’s take a look at the heating and cooling processes and how they’re controlled by a reversing valve. Also, zone systems allow different rooms to have different temperature needs, which can increase energy efficiency and reduce costs.

  1. Heating process:

A ductless heat pump is a great way to transfer heat from one place to another. It uses electricity and a refrigerant to suck up heat from the outside air and move it indoors. The compressor then increases the temperature of the refrigerant. When it gets to the inside, a fan releases the heat into the air of the room.

This type of heating is much more efficient than central heating. It also lets you independently regulate the temperature of each room. Plus, you can get two-way or three-way inverters.

If you live in an area with an average winter temperature above freezing, a ductless heat pump is the perfect choice. For hotter zones, ductless mini-splits are ideal for cooling.

The US Department of Energy says you can save money and energy by replacing your current heating system with a ductless pump. So, why not get a cool companion and save some cash?

  1. Cooling process:

A ductless heat pump transfers hot air from indoors to outdoors. It absorbs heat from an evaporator coil with refrigerant. The refrigerant is pumped through a compressor, releasing heat outside. Then cooled liquid flows back inside through an expansion valve, cooling the indoor space.

This process is energy efficient and has no fuel or combustion emissions. Plus, no ducts mean less energy waste. Plus, it gives you individual control over each indoor unit.

Furthermore, this heat pump can do both heating and cooling! It reverses the flow of refrigerant. For cold climates under 0°C, it adds electric-resistant coils for extra heating.

The idea for heat pumps came from Lord Kelvin in 1852. But the first patent was by David Chapman at the York Corporation in 1928. Later, compressor tech made geothermal pumps more efficient, and air source pumps fit for homes.

  1. Reversing valve:

The Direction-changer Valve is the mechanism responsible for controlling the flow of refrigerant and reversing the heating and cooling cycles of a ductless heat pump. It’s referred to as the ‘reversing valve’.

Here’s a table with the positions of the valve for heating or cooling:

Reversing Valve PositionFunction
Heating ModeTransfers heat from outdoor air to indoors.
Cooling ModeTransfers heat from indoors to outdoor air.

It energizes when the thermostat switches between heating and cooling modes

  • In heating mode, the compressor pumps refrigerant through an indoor unit while absorbing heat outside via the outdoor unit’s fan coil.
  •  In cooling mode, refrigerant pumped through an indoor unit releases absorbed heat outdoors.

It has four ports connected to different portions of the evaporator coil circuitry. An installation needs a trained technician who will accurately examine the home or commercial building.

A service call from a homeowner led to the discovery of wire damage causing the reversing valve failure. The technician fixed the issue quickly.

Zone systems make it easy to keep your home comfortable; no more temperature wars!

  1. Zone systems:

Say adieu to bulky ductwork and ‘hello’ to proficient cooling and heating with a ductless heat pump!

A zone control system provides custom-built heating and cooling processes in different parts of a building. It consists of many thermostats that are connected to one central unit, granting distinctive temperature control for various zones.

Compared to the traditional thermostat which is used to regulate the temp of an entire house, zone systems are more efficient.

 The thermostats are programmable, allowing them to regulate each zone’s temperature precisely when it’s needed, reducing energy expenditure.

Plus, ductless heat pumps provide this zone-based system too. With it, homeowners can adjust temperatures based on the requirements of every room or zone without influencing others.

Fun Fact: The base technology for ductless forms of AC/heating was invented about thirty years ago by Japanese makers who were looking for an alternative to the inefficient radiator heater systems that were common back then!

Poorly maintained systems, per U.S. Department Of Energy Sources, use up to 50% more energy than well-maintained ones. Invest in consistent climate control and energy efficiency!

Frequently Asked Questions.

Q. How does a ductless heat pump work?

A: A ductless heat pump works by transferring heat energy between the indoor and outdoor units of the system. The outdoor unit contains a compressor that compresses and heats refrigerant, which then moves through a refrigerant line and into the indoor unit. There, an expansion valve lowers the pressure of the refrigerant and allows it to evaporate to cool the indoor air. This process is reversed for heating.

Q. What is a ductless heat pump?

A: A ductless heat pump is a heating and cooling system that does not require ductwork to deliver conditioned air to living spaces. Instead, it consists of one or more outdoor units and indoor air handling units that can be mounted on walls or ceilings to deliver warm or cool air directly to specific areas of a home or building.

Q. What are the advantages of a ductless heat pump?

A: The advantages of a ductless heat pump include energy efficiency, zone control, easy installation, and increased comfort. Ductless heat pumps are more energy-efficient than traditional HVAC systems because they deliver conditioned air directly to living spaces, rather than through ductwork that can leak or lose heat. They also allow for zone control, so homeowners can heat or cool specific areas of their homes according to their temperature needs. Ductless systems are also easier and less disruptive to install than traditional HVAC systems, and they provide more consistent comfort by avoiding issues caused by ductwork.

Q. How much does a ductless heat pump system cost?

A: The cost of a ductless heat pump system typically ranges from $3,000 to $7,500 for a single-zone system. Multi-zone systems typically cost more, depending on the number of indoor units required. The installation cost varies depending on factors such as the area and space where the system will be installed, and the complexity of the installation process.

Q. What are some features of a ductless heat pump system?

A: Some features of a ductless heat pump system include smart AC controllers that allow for remote control of the system and geofencing to adjust the temperature based on the location of the homeowner. Many units also have multi-speed fans, reversing valves for heating and cooling, and adjustable temperature control for increased comfort. Some ductless heat pumps also have high energy efficiency ratios for lower energy bills.

Q. Do I need an HVAC technician to install a ductless heat pump system?

A: While it is possible to install a ductless heat pump system yourself, it is generally recommended that homeowners hire a licensed HVAC technician to handle the installation process. This is because ductless systems require the installation of components such as outdoor units, refrigerant lines, and indoor air handling units, which can be complex and may require professional expertise to ensure proper installation.


Analyzing the benefits, costs, and maintenance of a ductless heat pump system, it’s clear it’s an energy-efficient solution. No duct work is needed – installation is easier. Plus, with proper maintenance, the indoor and outdoor units can last up to 20 years. One great thing about a ductless heat pump is its zoning capability. Each room can have different temperatures. Multi-zone systems provide even better precision. Compared to other systems, the cost and energy efficiency ratio are low. I had a client with window heat pumps to cool their home. High energy bills and insufficient cooling though. So, I suggested a new ductless heat pump install. We drilled only a three-inch hole in the wall, connected refrigerant lines and suction tubing, installed indoor units, and set up geofencing and smart AC controllers. It was quick and efficient. Now, my client is more comfortable and saving money on monthly energy bills.
