Why Are They Called Ductless Mini Splits?

They’re called ductless mini splits because they don’t require ductwork and consist of two main components—a compact indoor air handler and an outdoor compressor—connected by refrigerant lines. This “split” design allows for efficient, targeted heating and cooling in specific areas.

If you want a versatile HVAC system you can customize from room to room in your Pittsburgh, home, look no further than a ductless mini split.

Like many other homeowners, you may have heard about mini splits but do not know how they work. You might wonder why they are called mini splits or ask, “Will a ductless mini split benefit me?”

These highly efficient systems work year-round to both heat and cool without ductwork. At Air Synergy, we install the best HVAC systems and would love to help you transform your home comfort with a ductless mini split.

In the meantime, this blog will explore everything you need to know about mini splits, from their unusual name to benefits to why you might need one.

Why Is It Called a Mini Split?

The answer is in the mini split’s design.

The system is split into two parts: an indoor air handling unit and an outdoor unit. Mini split units are compact and take up little space compared to conventional, ducted central air systems.

Unlike traditional HVAC systems that use ducts to deliver conditioned air throughout your home, a mini split does not require ductwork. This makes it a perfect solution for homes or spaces without existing ductwork or where installation would be costly and invasive.

How Does a Mini Split Work?

In the summer, a ductless mini split moves heat from your Pittsburgh home and transfers it via refrigerant to the outdoors. In the winter, it extracts heat from outside to inside your home. 

Its outdoor unit contains the compressor and condenser, which is similar to a ducted heat pump.

The indoor unit, which mounts on the wall or ceiling, houses an evaporator coil, fan, and filters, like an air handler in a ducted system. While a central air handler distributes air to ductwork, a mini split’s indoor unit blows it directly into an individual room or heating and cooling zone.

Personalized HVAC Zoning Comfort With Ductless

The outdoor unit can connect to several indoor units, creating an HVAC zone control system throughout your home. Each indoor unit has an independent thermostat, allowing you to customize comfort in your living space.

You can set the temperature higher in one room, lower in the next, or turn it off in a rarely used space. For example, you might want more heat in a room on the north side of your home and less in a space with large, south-facing windows. A customized heating and cooling strategy can help you reduce energy consumption and save money on utility bills.

Are Mini Splits Efficient?

Ductless mini splits are known for their energy efficiency. Since they blow conditioned air directly into their surroundings through indoor air handling units, they do not lose energy through leaks or poorly insulated ducts.

Up to 30 percent of conditioned air moving through the ductwork in an average home escapes through cracks, holes, and poor connections, resulting in higher utility bills. That’s money escaping through those cracks!

Mini splits use inverter technology, which allows them to adjust the compressor speed based on the current heating or cooling demand rather than turning it on and off frequently. This saves you money on utility bills and reduces your carbon footprint.

Do Mini Splits Improve Indoor Air Quality (IAQ)?

Ductwork can accumulate dust, dirt, and other allergens, which can circulate through your home, but since mini splits do not use ductwork, they can improve indoor air quality. Mini split systems also use filters to help purify the air.

Are Mini Splits Difficult to Install?

At Air Synergy, we can install a ductless mini split quicker than we can a conventional ducted HVAC system. Mini splits are less invasive, with each indoor unit requiring a small hole in the wall where it connects with refrigerant lines.

Ductwork installation, on the other hand, typically cuts into walls or ceilings, requiring alterations to your home.

Why Would I Need a Mini Split?

A ductless mini split is an excellent choice if you live in an older home without ductwork. It offers all the heating and cooling benefits of a traditional system, plus energy efficiency and customized comfort—without installing ductwork.

A mini split is the most practical HVAC option besides portable heating and cooling units for detached buildings such as a remodeled garage or shed. Installing a ducted system in your backyard accessory building does not make good financial sense and extending ductwork from your home is impractical and may be impossible.

Consider installing a mini split if you cannot extend ductwork into a home addition or have an area, such as an attic, where your forced air system struggles to heat and cool.

A mini split can fulfill your need for customized comfort, enabling you to select different temperatures from room to room.
