Ductless Mini-Splits: What They Are and How They Can Benefit You

Have you ever heard of a ductless mini-split? Mini-split systems are typically more prevalent in areas of the country where the buildings lack central heating and cooling. Today, we will explain what mini-splits are, how they work, and how they differ from traditional HVAC systems. Hopefully, by the time you finish this article, you should have a better idea of whether a ductless AC unit NJ (or several) is the right HVAC solution for you.

What Is a Ductless AC Unit?

Ductless mini-splits, as the name implies, do not require ductwork to operate. A central air conditioner uses a single unit to distribute air throughout a home. Whereas, a ductless mini-split services a single room or area and has both an indoor and outdoor unit, which is where the term “split” comes in. Ductless mini-splits are a fantastic HVAC solution for many homes since they are extremely energy-efficient and can provide cooled and heated air to rooms that don’t contain ductwork. These units are referred to as “mini” since the unit heads are smaller than central air conditioners and furnaces.

Where Should You Install a Ductless AC Unit?

These are the most common areas for ductless mini-splits.


It’s illegal to install ductwork in garages due to possible safety hazards. Without heating or cooling, it can be uncomfortable for homeowners that enjoy working out of their garages to do so. But, a ductless AC unit NJ allows you to control the temperature in your garage throughout the year!

Master Bedrooms

Master bedrooms are often the furthest rooms away from the central HVAC system and can greatly suffer as a result. If your bedroom is constantly too hot or cold, a ductless system may be preferable to replacing your existing ductwork.

Finished Basements

If your basement is finished, you will most likely want to use it, whether it’s for parties, hangouts, or showing off your awesome new pool table. Unfortunately, spending time in a basement that does not get heated or cooled air can be extremely uncomfortable. You will, however, be able to manage the temperature of your finished basement if you install a ductless mini-split!


Ductwork may not reach rooms on the top floor of your home, such as your attic, in the same way that it may not reach the master bedrooms or basement. As a result, your attic may feel hot and stuffy. Fortunately, a ductless AC unit NJ will help alleviate your issues.

Slab Homes

Heating and cooling units are often placed in the basement. However, since slab homes don’t have basements, they often lack adequate heating and cooling options. In this case, installing a ductless mini-split system with multiple units or heads would be your best option.

How Does a Ductless AC Unit Work?

Some ductless AC units are only capable of cooling a home, while others can both heat and cool homes. The heating/cooling system functions similarly to a heat pump in that it transports heat from the outside to the inside, making it an incredibly energy-efficient HVAC solution.Another unique feature of ductless mini-splits is that they have the ability to accommodate several units or heads. A single outdoor unit can support up to eight indoor heads, but most residential systems contain fewer. An outdoor unit can go up to 4-5 tons. The more heads you require, the higher the tonnage you’ll need. For example, if you only require a single mini-split head, you’ll likely only need a 0.5-ton outdoor unit, but if you have three heads, you’ll need a 2.5-ton outdoor unit. You can place heads in different rooms in your home, and set the temperature of each head however you see fit. This is one of the greatest advantages of ductless mini-splits over central heating and cooling systems. While central heating and cooling systems can service an entire house better, ductless mini-splits provide greater control.

Where Can You Mount a Ductless Unit?

You’re probably most familiar with the wall-hung units, but you can also mount ductless mini-splits from the ceiling or near the floor.

Ductless Mini-Split Efficiency and Lifespan

Ductless mini-splits are extremely energy-efficient and can have a SEER rating (Seasonal Energy Efficiency Ratio) of up to 30! Traditional central air conditioners, on the other hand, can have a SEER rating of up to 23. Additionally, with an HSPF (Heating Seasonal Performance Factor) rating of up to 13.5, ductless mini-splits are one of the most energy-efficient heating options on the market. The use of inverter technology and a variable-speed compressor allows ductless mini-splits to be so efficient. Because they convert high voltage electricity into DC voltage, the equipment uses less electricity to do more work. Since a variable-speed compressor is used, a ductless mini-split unit can blast out air at higher or lower speeds to reach the preset temperature instead of frequently turning on and off. The only downside of ductless mini-splits is that a single head won’t cool or heat your entire house, but it will be incredibly efficient for the area it is covering.Your ductless AC unit NJ should last 12-15 years if properly maintained. Unfortunately, many homeowners overlook mini-split maintenance more often than whole-house system maintenance, resulting in a shorter lifespan. Remember to schedule routine maintenance check-ups!


When it comes to ductless mini-split installation you have two options; DIY or professional installation. While the choice is entirely up to you since it’s your home, we recommend hiring a professional HVAC technician for installation. If you opt to install a ductless AC unit on your own, you’ll have to purchase special tools (which can be very expensive), have knowledge of carpentry and welding, and be willing to waive your warranty. If you need to make repairs, finding replacement parts for your model can be extremely difficult on your own.On the other hand, when you hire a professional HVAC company like Quick Serve Pro, you can be confident that the equipment will be installed correctly, tested to ensure optimal performance, and will be maintained to prolong its life and efficiency.

Who Should Consider a Ductless AC Unit?

If you own a slab home or an older home that doesn’t have any room for ductwork, a ductless HVAC system is your best option. Even if your home is on the newer side and has enough room, you may want to consider a ductless system if you’re on a tight budget. This is because adding ductwork to your home can cost thousands of dollars.If you have a central HVAC system but a room in your home doesn’t get cooled or heated air, you can install a single ductless AC unit NJ. As we discussed above, some examples of these “nuisance” areas are garages, attics, basements, and master bedrooms. A ductless mini-split can make all of the difference between loving a room and never using it.If you’re interested in exploring ductless mini-split options and live in New Jersey, reach out to Quick Serve Pro.
