Mini splits give modern homes a more comfortable and simpler way to regulate temperature, both cooling and heating, and are a better alternative to traditional central air conditioning. But are they really worth the investment? In this comprehensive guide, we'll break down the pros and cons of mini splits to find out if a mini split AC fits for you. Read on!
What is a Split AC System and How Does It Work?
A split AC system, also known as a ductless mini split, is a modern heating and cooling solution designed to provide comfort without the need for extensive ductwork.
It consists of two main components: an outdoor unit and one or more indoor units. The outdoor unit houses the compressor and condenser, which are responsible for cooling or heating the refrigerant.
The indoor units, typically mounted on walls or ceilings, distribute the conditioned air directly into the room. These two components are connected by a small conduit that carries refrigerant, power, and drainage lines.
The mini split heat pump works by transferring heat between the indoor and outdoor units. During cooling, the indoor unit absorbs heat from the room and transfers it outside, while in heating mode, the process is reversed, pulling heat from the outdoor air and bringing it inside.
This efficient heat exchange process, combined with inverter technology, allows split AC systems to adjust their output based on the room's needs.
Split AC systems are highly versatile, making them ideal for homes without existing ductwork or for those looking to add climate control to specific areas.
Their compact design and flexible installation options make them a popular choice for modern homeowners seeking an efficient and customizable HVAC solution.
Advantages of Mini Splits
Energy efficient
Mini split air conditioners are great at saving energy which is not only better for the planet, but also for lowering your utility bills. Since they don't use ducts, there's less energy loss. They also have inverter technology, which adjusts the compressor speed based on what's needed, using only the energy required and making the entire operation very quiet.
According to tests in Della Labs, compared to traditional HVAC systems, mini split air conditioners can save up to 25–40% on energy costs. For example, Della's mini split air conditioners for sale can reach a SEER2 rating of 20 and save energy costs by more than 40%.
Easy installation
Ductless mini splits are easy to install since they don't require ducts. The process is quick and less disruptive, with just a small conduit connecting the indoor and outdoor units. You can place them in almost any room without much hassle.
Independent room control
The mini splits air conditioning allow you to control the temperature in each room separately. Through this feature, you can keep one room cool while another stays warmer, giving everyone in the house personalized comfort.
Quiet operation
As located away from the outdoor unit, mini split units run very quietly indoors. The indoor units are designed to produce minimal noise, so you can enjoy a comfortable temperature without any loud distractions.
Space-saving design
Ductless mini splits are compact and take up less space than traditional HVAC systems. The indoor units can be mounted on walls, ceilings, or floors, fitting neatly into any room without the need for large ducts or major renovations.
Improved air quality
Mini splits air conditioning have advanced filters that reduce dust, pollen, and allergens, improving indoor air quality rather than circulating dust and pollutions like traditional central air systems.
Disadvantages of Mini Splits
Higher upfront cost
Ductless mini splits installation costs are higher compared to traditional HVAC systems. For a single-zone mini split system, the cost can range from $2,000 to $5,000, including the unit and installation.
Aesthetic impact of indoor units
The indoor units of ductless mini splits are visible and may not blend seamlessly with all interior designs. Some homeowners might find them less aesthetically pleasing compared to hidden ductwork.
Regular maintenance needed
Ductless mini split air conditioners require regular maintenance to ensure they operate efficiently. This includes cleaning the filters, checking the refrigerant levels, and inspecting the system for any issues.
Limited coverage for large spaces
To cover large homes or areas adequately, you might need multiple units, which can raise costs and be less convenient to control than a central air system.
Are Split HVAC Systems Worth It?
Split HVAC systems, especially ductless mini splits, are a great investment for many homeowners due to their energy efficiency, flexibility, and zoning capabilities.
Unlike traditional central air systems, mini splits let you control temperatures in individual rooms, reducing energy waste. They’re ideal for homes without ductwork, avoiding costly modifications. With advanced inverter technology, they use less energy and lower utility bills over time.
How Much Will My Electric Bill Go Up with a Mini Split System?
The impact on your electric bill depends on system efficiency, usage, and home size.
Mini splits generally use 25–40% less energy than traditional HVAC systems due to their ductless design and inverter technology. On average, running a single-zone mini split costs about $20–$50 per month, while a multi-zone system can range from $50–$150 per month.
If replacing an outdated central system, you may see overall savings. However, adding a mini split for supplemental cooling or heating can slightly increase your bill.
Do Mini Splits Devalue a House?
Mini splits do not typically devalue a house. In fact, they can often be seen as an upgrade due to their energy efficiency, quiet operation, and the ability to provide zoned heating and cooling. Buyers may appreciate the lower utility costs and the flexibility these systems offer. However, some buyers might have aesthetic concerns about the appearance of indoor units, but this is generally a minor issue.
