What Is a Mini Split Heat Pump?

A mini-split heat pump is a compact heating and cooling system that enables you to control the temperature in homes or individual spaces. A mini-split heat pump is comprised of two components; an outdoor compressor and an indoor air-handling unit. It is extremely easy to install and requires only a three-inch hole through the wall for the conduit.

The conduit comprises the communication and power cables alongside a copper tubing and condensation drain line that links both the units. Mini-split heat pumps are an excellent solution for entire homes or individual spaces. They can also be handy for room additions where duct-work is not viable.

PIONEER Air Conditioner Pioneer Mini Split Heat Pump

How Does a Mini Split Heat Pump Work?

The mini-split heat pump is comprised of two main parts; the air-handling unit and the outdoor compressor. The indoor unit is usually mounted on a wall that delivers conditioned air directly in the individual space. The indoor unit is connected to the outdoor condenser through a refrigerant line.

In addition, the duct opening in the wall houses a copper tubing, power, and communication cables along with a condensation drain line. The outdoor compressor absorbs the air from the atmosphere and processes it through a series of complex procedures. Ultimately, the cool or warm air is then dissipated into the living space through the indoor air-handling unit.

Types of Mini Split Heat Pumps

Mini-split heat pumps are of different kinds. These include:

Wall Mount

It is a type of mini-split heat pump that comprises of an outdoor compressor usually installed outside. An indoor air-handling unit is installed in the living space. The air from the outside is processed by the condenser and enters the living space through the inner unit. It is highly efficient and elegant for cooling and heating rooms and even entire houses.

Ceiling Cassette

As the name suggests, the ceiling cassette is usually installed in a ceiling. It’s generally placed in the center of the room to ensure equal heating and cooling effect throughout the living space.

Concealed Duct or Ceiling Concealed

It is a ducted model. It generally requires ductwork before it can be installed and operated. The air-handling evaporator is fitted into the ceiling. All that is visible is the unit’s louvers. This is an expensive choice if your home doesn’t possess ducts.

Ceiling Suspended

These are the type of mini-split heat systems that are usually suspended by rods adjacent to the room’s wall. Their one side is attached to the ceiling.

Floor Standing

Floor standing units are also known as Floor Mount systems. They are ideal for angled ceilings and can be found in kitchens. Usually, you would probably notice their back against the wall. They can also be installed under windows.

How to Install a Mini Split Heat Pump

Here is a step-by-step installation guide for how to install a mini-split heat pump

1. Tools and Unboxing

A mini-split heat pump comes with an outdoor condenser and an indoor air-handling unit. The first thing you have to do is look for any damages. After a thorough look, you are ready to start the installation. To install a ductless mini-split heat pump, you will require certain tools for effective and proper installation.

2. Assemble the Wall Bracket

You probably need to drill a few holes in the wall, as provided in the instruction manual. This will help you install the indoor air handling unit against the wall.

3. Drill Hole for the Refrigerant Line

The next thing you want to do is drill a 3-inch hole in the wall and install the round plastic sleeve into the hole. Finally, you would be able to feed the refrigerant line through the hole where it can be connected to the outdoor compressor.

4. Mount the Outside Unit

With the help of a wall bracket or pad, install the outdoor unit as you desire.

5. Connect the Refrigerant Line and Electrical Lines

Remove the plastic seals found on the compressor and align the refrigerant piping properly while you connect them. Then, connect the electrical lines from the inner unit to the outer unit and seal the electrical connections properly. Check for any leaks using dawn soap and water. You might want to hire an HVAC professional for the last part.

Before you start the installation, remember to follow the guidelines given in the instruction manual. However, if you still have questions regarding the installation, make sure to refer to the video below for a full overview of what was just described.  


If you want a highly reliable and energy-efficient heating solution, then look no further. These ductless mini-split heat pump systems can provide you with the best heating and cooling system for your living space. Consider investing in a mini-split unit while being highly cost-effective.

People Also Ask                                    

There are always some questions left in the mind of the buyer, which better not be left unattended. To make sure the buyers are satisfied by the purchase, certain questions need to be addressed adequately. We have prepared a list of questions to make sure that you have no queries left.

What Temperature Is a Heat Pump Not Effective?

A heat pump is not effective in temperatures like 25 to 30 degrees Fahrenheit. However, the good news is that nowadays, modern technology provides a broader temperature range for its users. There are heat pumps available that can operate efficiently in temperatures as low as 5-degrees Fahrenheit.

How Long Will a Mini Split Last?

Mini-split heat pumps generally last longer when compared to traditional heating or cooling systems. The reason is the absence of ductwork. However, the reliability of a heat pump greatly depends upon regular maintenance, its usage, and the quality of the mini-split system. 

Should I Turn My Heat Pump Off in Extreme Cold?

The answer is no. You don’t have to turn off your heat pump in the extreme cold unless you really have to. Modern heat pumps possess backup heat strips in emergency situations when heating is ineffective. They are usually electric coils that use electricity to produce heat, which can result in higher electricity consumption.

Should I Cover My Heat Pump in the Winter?

No, you should not cover your heat pump in the winter. Heat pumps take the air from the atmosphere and heat it up before it dissipates through the inner unit. Covering the heat pump would only result in ineffective heating since the air won’t be absorbed properly.

How Do I Protect My Heat Pump From Ice?

In order to protect your heat pump from ice, make sure the unit is not suffering from a dense covering of ice. Make sure to remove the ice carefully two feet in front and top of the unit for proper airflow. Check your unit every once in a while. If the ice problem is beyond your control, contact an HVAC professional for further help and guidance.

How Often Should My Heat Pump Cycle?

Usually, most heat pumps should run 2-3 cycles per hour. In mild weather conditions, a cycle can be as long as 10 to 15 minutes. However, the closer you get to the maximum designed temperature, whether it is heating or cooling, the longer the cycle for the heat pump.

Do Heat Pumps Use Freon?

A heat pump operates by removing heat from one place and dissipating it into another. To do so, it uses a special type of liquid known as refrigerant. A refrigerant possesses the ability to shift liquid and gas state quickly and absorb heat effectively. Freon is a brand of refrigerant that can absorb heat effectively, making it a possible refrigerant for heat pumps.
