Benefits Of Mini Split Heating and Cooling

Mini split systems, also known as ductless systems, offer a range of benefits from superior comfort to energy savings. Here are a few of our favorite advantages to installing ductless mini splits for heating and cooling.

Superior Comfort

Mini splits are adept at maintaining consistent temperatures across different rooms. Unlike traditional HVAC systems that may produce uneven temperatures due to ductwork losses or design limitations, mini splits can target specific areas, ensuring each room is precisely comfortable.


One of our favorite benefits of ductless mini splits is how customizable they are. With individual air handling units for different zones or rooms, you can tailor temperatures to personal preferences and reduce energy waste by not heating or cooling unused spaces.

With a traditional HVAC system, the entire home is set to the same temperature. With these zoned HVAC systems, you don’t have to try and force each space in the home to be the same temperature.


Mini splits offer flexibility in both installation and application. They can be installed in new construction, as a retrofit to existing buildings without ductwork, or as a supplement to existing HVAC systems. Their compact size and variety of indoor unit styles make them adaptable to any interior design.

You can install units that hang on the walls, are mounted on the floor, or cassettes in the ceiling. Their flexibility also makes them a great option for sunrooms and patios without existing ductwork.

Whisper-Quiet Operation

One of the hallmark features of mini split systems is their whisper-quiet operation. Traditional HVAC systems can be noisy, with the rumble of air through ducts and the clatter of the furnace kicking in. Window AC units are even worse, and can ruin the peace of a living room or a home office. Mini splits, conversely, are designed to be nearly silent, so you barely notice they are even running!

Lower Energy Bills

The efficiency of mini splits can translate into lower energy bills. With no ducts, energy loss commonly associated with ductwork of central forced air systems is avoided.

Mini splits also utilize inverter technology, which allows them to adjust the compressor speed and maintain consistent temperatures without the energy-intensive on/off cycles of traditional HVAC systems.

In simpler terms, instead of letting the temperature fluctuate, and turning off and on to compensate, these systems run at a lower, steadier mode. This saves energy and improves comfort. Using this heat pump technology is a great way to save money and stay comfy.

Disadvantages of Mini Split Systems

Despite the appealing advantages, there are also a few disadvantages of mini split systems to consider before investing.

Multiple Units

One of the mini split cons often discussed is the need for multiple indoor units to heat and cool entire homes. This means each zone or room you wish to condition requires its own air handler, which can become expensive to install, despite the improved comfort.

High Upfront Cost

The initial cost of purchasing and installing a mini split system can be higher than traditional HVAC systems, especially when multiple indoor units are required. While energy savings over time can offset this cost, the upfront investment is something homeowners need to prepare for.

Luckily, there are rebates, tax credits, and financing options to curb these costs. The experts at Blue Ridge can help you find the best deal for your new system.

More Maintenance

Mini splits require regular maintenance to perform efficiently. Each unit needs to have its filters cleaned and occasionally replaced. While not necessarily high maintenance, the chore of maintaining multiple units can be a con for some homeowners. The fortunate thing is most of this is DIY, and you really only need a professional to look at your system once a year.

Our Conclusion

Considering the mini split pros and cons, these systems can be an excellent investment for homeowners looking for customizable, efficient heating and cooling options. Even if the upfront cost is a bit higher, these systems have lots of options to save on installation and can cut energy costs for years to come.

Are mini splits high maintenance?

While mini splits do require regular maintenance, such as cleaning filters and ensuring outdoor units are clear of debris, they are not necessarily high maintenance. Proper upkeep will ensure efficient operation and longevity of the system. You should have a deep cleaning bi-annually.

Is it bad to run a mini split all day?

Running a mini split all day is not bad, especially since these systems are designed for efficient, prolonged use. The inverter technology allows them to adjust power use to maintain a set temperature rather than cycling on and off repeatedly, which can be more energy-intensive.

Is heating with a mini split expensive?

Heating with a mini split is generally not expensive compared to traditional heating systems. Their high energy efficiency translates to lower operating costs. They also allow for you to use each zone independently, improving comfort and lowering energy use.
