Having your home consistently maintain the right temperature is one of the most satisfying achievements. While there are different ways attain this comfort, smart mini-split systems are becoming increasingly popular. These systems are efficient and scalable when it comes to adding heating and cooling to your home. However, they operate differently from the usual heating, ventilation, and air conditioning (HVAC) systems. Since 1998, 72 Degrees Heating & Air Conditioning has been the preferred HVAC company in Apex, NC, and our HVAC technicians can help answer your questions about mini-splits.

The Basics

A mini-split system comprises two primary components: an indoor unit, also called an air handling unit, and an outdoor unit, also referred to as a compressor. The primary reason that the mini-split has become a popular heating and cooling system is that it operates using less energy in several ways. It is equipped with variable-speed compressor technology, which helps maintain the desired temperature. On moderate days, the system does not require the compressor to run at full speed, thereby conserving energy. Because of these advantages, if you plan to replace your HVAC system or build a new home, a smart mini-split system is worth considering.

Mini-Split System Pros

Smart mini-split systems present multiple clear advantages over a traditional HVAC system, making it worthy of consideration.

Increased Energy Efficiency

Mini-split systems are widely used for their energy efficiency that is achieved through their unique operation. They are known to be 20% to 35% more efficient than traditional cooling and heating units for two reasons. First, their inverter technology allows the compressor to adapt to the system’s needs by slowing down or speeding up instead of shutting off, thereby maintaining optimal temperatures.

Second, unlike traditional furnaces, these ductless units do not lose up to 30% of the overall cooling and heating energy. Instead, they deliver conditioned air directly to selected rooms in your home, saving the cost of cooling and heating unused spaces and resulting in lower utility bills. Moreover, no energy is lost since the conditioned air moves through the ductwork.

By installing a mini-split system, you no longer have to heat or cool your entire home just to achieve optimal temperatures in one room. The more energy efficient your home’s cooling and heating system, the lower your energy bills will be.

Minimal Noise Levels

Mini-split systems are a popular choice due to their quiet operation. They have some of the lowest decibel ratings (dB), which measure sound levels that the human ear can easily detect. Anything below 40 dB is considered quiet.

To ensure indoor comfort, we recommend checking the dB levels of a system before purchasing. Most modern models from reputable brands have decibel ratings in the quiet range. To ensure silent operation, it’s essential to have our experienced technicians handle the installation. Improper setup can cause significant noise-related issues. Regular maintenance also plays a crucial role in noise regulation.

Better Air Quality

Mini-split systems are an efficient way to control the temperature in your home and improve air quality. Traditional central air conditioners rely on ductwork to distribute temperatures, but over time, this can lead to clogging and poor air quality, which can cause respiratory illnesses. Ductless mini-split systems prevent allergens, dust, and debris from accumulating in the ducts, resulting in better air quality. Investing in a mini-split system may be a viable solution if you or your family members have respiratory problems.

Built-In Zoning

The system has a built-in zoning capacity that allows you to control the temperature in each room independently. This feature is handy if you have different cooling and heating needs for each zone. You can adjust and program each unit to work on a given schedule to ensure the system runs when needed. Your mini-split selective operation means less energy consumption, reduced wear and tear, and unique temperature control. Homeowners looking for a cost-effective and customizable unit for maintaining optimal temperatures all year round should consider this system.

Easy Installation

Mini-split systems are an easy and efficient alternative to traditional HVAC systems. Unlike central units, mini-splits do not require ductwork, making them easy to install. However, it is important to note that homeowners should not attempt do-it-yourself installations. Professional HVAC technicians are needed for quick and efficient installation, and only a few components are necessary for the connection. In most cases, only a small hole must be drilled for the conduit to pass through, making the installation less intrusive. Since mini-split systems do not use ducts, air loss through leaks is less likely. This easy installation process saves both time and money for the homeowner.

Room for Renovations

If you’re planning to renovate your home, a mini-split system can be an excellent option for heating or cooling your space without extending your ductwork. Traditional HVAC systems can be expensive and often require significant changes to your home’s structure, including installing additional ductwork. In contrast, mini-split systems only need a small hole to connect the indoor and outdoor units. The simplicity of mini-split installation means you won’t have to compromise the design of your home to enjoy optimal temperatures. It’s ideal for those who want to renovate their homes without altering their HVAC systems.

Mini-Split System Cons

While mini-split systems offer notable benefits over traditional HVAC systems, they also depict unique drawbacks you may need to consider before making your final purchase.


Like all other air conditioning units, mini-split systems can also be considered an investment. Even though the upfront cost may be higher than that of conventional units, due to the unit’s price, the need for a licensed technician, and the installation process, they can save you more money in the long run. Mini-split systems come with built-in zoning capacity and energy-efficiency capabilities, which can lower your utility bills and reduce energy waste.

Aesthetic Appeal

Many homeowners have expressed dissatisfaction with the appearance of indoor units. Although these units are designed to be discreet, they must be installed on walls or ceilings, which some people find unappealing. Unlike conventional units with ducts hidden behind walls, attics, and ceilings, the mini-split system requires indoor units for each area that needs heating or cooling. However, slim and stylish designs cater to modern design preferences.

With a mini-split system, you may have noticed that the advantages outweigh the disadvantages. We feel that a mini-split is a perfect choice for the right application.
