Ductless mini-split cooling and heating units provide all the advantages of an HVAC system. However, they take up less space and don’t require ductwork. This is ideal if you have a home that is older and installing ductwork is not practical. This is also a good solution if you want to upgrade your current equipment or you want to add another HVAC unit to the system you currently have. Nevertheless, it is important that when you choose to invest in a ductless system, you should opt for a professional ductless installation.

How A Mini-Split System Works

Ductless HVAC units have two principal parts: a condenser that is outdoors and an air handler that is indoors. These components link by a conduit line that channels through a hole about three inches in the wall. The duct line consists of a line for refrigerant, a drain for condensation, and a cable for power. Depending on your level of comfort, you may have multiple air handlers installed in your house.

A mini-split that has a ductless heat pump fitted can provide warm air on cold winter days and cold air in the hot summer season. A ductless unit functions by rotating refrigerant through the conduit line that links the indoor and outdoor units. The refrigerant absorbs the heat inside and then discharges it outside. The process reverses when the system is in heating mode.


Benefits Of A Ductless Mini-Split

Because of the many advantages of a mini-split, many homeowners are making the switch to this type of system. These are a few of the benefits:

Streamlined Design

Mini-splits have a modern and sleek design that takes up little space and is low-profile. An HVAC contractor can mount a mini-split system to the floor, on a wall, or even hang it from the ceiling. The design is engineered to fit any living space without obstructing your interior design.


Noiseless Operation

With some mini-split systems rating at just 19dB for sound, this means they are not even as loud as a whisper. In addition to the discreet design, you can barely register that they are on at all.

Exceptional Home Comfort

Conventional HVAC units periodically turn on and off. Once it achieves the set temperature, the unit turns off. Then it turns back on when the temperature drops ( or raises) to a particular level. This unfortunately results in temperature swings that are either too hot or too cold.

A ductless system can have inverter technology equipped so that it can provide a room with continuous heating or cooling. In this way, you can have peace of mind knowing that there won’t be hot or cold areas within the room. Your house will be optimally comfortable at all times. This also reduces moisture when the system is running, assuring an even greater level of comfort in your home.

Efficient Energy

Out of all the systems on the market, ductless heat pumps are one of the most efficient. Mini-splits that are inverter-driven use variable speeds to cool and heat. Therefore, they reduce energy wastage. Ductless units also have advanced control algorithms and heat exchangers that are intelligently designed. They ensure that you save 30 percent or higher on the cost of energy.


Numerous HVAC Zones

House Zones

Another advantage of a ductless system is that it allows you to have zoning. Each zone has an individual air handler that gives you control and flexibility over the environment in your home. You can turn on the mini-split just in the rooms that you are occupying. In addition, you can control the temperature in each zone and tailor them depending on the preferences of each family member.

Single-Zone Ductless Systems

A single-zone ductless system is made up of one indoor and one outdoor unit. Single-zone systems are often used as a supplement to a space that has an HVAC unit that is under-serving the space. A single-zone system is also optimal for heating or cooling a room that was not conditioned before. One downside of opting for a single-zone system is that you cannot change it to a system with multi-zones at a later point.


Multi-Zone Ductless Systems

With a multi-zone ductless system, you have one unit outdoors and multiple air handlers indoors. One outdoor compressor can serve up to eight units indoors. This kind of zoning allows you to combine comfort, control, and efficiency in a way that no other HVAC system on the market has been able to duplicate.

Every indoor air handler works apart from the other units, which allows you and your family to enjoy tailored comfort in each zone in the home. For example, you can turn off any of the units in zones that are unoccupied. While the kids in the living room enjoy a warmer temperature, you can experience a cooler temperature in the bedroom.

Indoor Unit Types

There are multiple kinds of indoor units that can cater to your comfort needs in the home. Remember that the one you opt for should correspond to your preferences for aesthetics, as well as the layout of your house. These include:

  • Wall-Mounted Unit: This is the most commonly used type of mini-split unit and the most affordable choice compared to other units. With this unit, the air handler is generally mounted at a height of at least six feet on the wall. This is an efficient and compact system that comes with many features and has numerous designs.
  • Floor-Mounted Unit: A mini-split that is mounted on the floor is used when you do not have enough space on the walls to install a wall-mounted system. Floor-mounted units are placed on the floor near the bottom of the wall. This is ideal for a situation where the room that you want to condition has a sloping wall and ceiling, such as a room in an attic.
  • Ceiling Cassette Unit: A ceiling cassette mini-split unit is mounted into the ceiling, most often in the center of the ceiling. The majority of the mechanics are concealed within the ceiling. The only part visible in the room is the grille. The air conditioning is dispersed on each of the four sides. With this system, you can control which direction the air flows and shut some of the vents when necessary.
  • Suspended Ceiling Unit: As you can guess from the name, a suspended ceiling unit hangs from the ceiling. This type of unit can blend seamlessly into your living area and has the capacity to cool spaces that are larger. Office areas often have this type of system.

Hire An Expert Ductless Installer

Because there are many things to think about with ductless HVAC system installation, it should be left to the experts. When a local HVAC technician that is qualified installs your unit, it can function as well as it is capable of and provide long-lasting optimal efficiency.

A professional technician can ensure that you are assisted at every level of the installation, including opting for the correct system, finishing the installation, and checking on it afterward. These are a few of the benefits of having an HVAC system professionally installed:

The Correct New System

To heat and cool your home efficiently, it is crucial to match the right HVAC system to your needs. An expert knows how to assess your living space and what you need on a daily basis. They can use this knowledge to determine the capacity and size of your new ductless mini-split system. Buying a ductless system without this knowledge could be disastrous. It could result in you purchasing an HVAC unit that is too big or too small for what you need. This could result in further inconveniences including poor performance, high utility bills, and low air quality. An expert technician will make sure that your ductless HVAC system is ideal for your house and level of comfort.

Installation That Is Safe And Easy

Even though it might seem like a ductless system installation is easy because it only takes a few hours, the installation process is not as easy as it seems. An expert has a great deal of experience and the proper tools to guarantee that the HVAC unit does not get damaged while being installed.

Safety is one of the key reasons why you need to employ a professional HVAC technician. A ductless mini-split unit is a sophisticated piece of equipment. HVAC technicians must train for years to understand how the various components of an HVAC unit work and function together. It can be dangerous to install a ductless system by yourself because you will be in direct contact with electrical wiring and refrigerants.

HVAC manufacturers apply as many safety mechanisms as possible into their cooling and heating products. That being said, if the system is not handled properly, something could still go wrong. Without the correct tools, knowledge, and skills, you could cause damage and even increase your costs more. Putting your trust in a professional technician ensures that your installation is safe, secure, and cost-effective so that your home has long-lasting benefits.

Increased Efficiency And Longer System Lifespan

Your ductless mini-split system’s efficiency and lifespan can be determined by the quality of the installation. Any cooling and heating system that is improperly installed cannot run as effectively and efficiently as it should. The results of this are poor performance and increased energy costs.

You will receive the best return on your investment from properly installing your unit. An expert will make sure that the unit works at the optimum efficiency so that you get the comfort levels in your home that you want as well as the cost savings you expect.
