The Difference Between Ductless Mini-Splits and Traditional AC
The key difference between ductless mini-splits and traditional AC systems is the way they distribute conditioned air. Traditional AC units use ductwork to transport the air throughout the building, while ductless mini-splits operate, as the name would suggest, without ducts. Instead, they consist of an outdoor compressor unit and one or more indoor air handlers that deliver conditioned air directly to specific zones or rooms.
The absence of ductwork in mini-split systems offers several advantages over the more traditional HVAC unit:
- Energy Efficiency: Mini-splits deliver air directly to specific zones or rooms. This eliminates the energy losses associated with duct leaks and inefficient distribution. These systems can be ideal for people who only want specific rooms to have conditioned air, such as a bedroom, a main living room, or a home office. This targeted approach to conditioning saves energy by avoiding the need to cool or heat the entire house when it is unnecessary.
- Indoor Air Quality: Traditional HVAC systems often accumulate dust, dirt, and allergens within the ductwork, which can be circulated into your living space. However, since it is the ducts that harbor pollutants, the absence of that ductwork can significantly reduce the chances of airborne contaminants making their way throughout your home.
- Quiet Operation: The compressor unit, which produces the most noise, is located outside the home, while the indoor units operate quietly. This allows you to enjoy a peaceful and comfortable environment without the constant hum and noise associated with traditional HVAC systems.
- Ductless Mini-Splits Can Heat and Cool: Mini-splits are designed to offer year-round comfort. They have a heat pump functionality that allows them to extract heat from the outdoor air and transfer it indoors during colder months. This makes them an efficient and cost-effective solution for both heating and cooling needs.
- Mini-Splits Can Heat and Cool Your Garage: Garages, he/she sheds, and similar structures, often lack ductwork. Thus, they cannot be connected to a traditional central AC system. Mini-splits eliminate this problem. By installing an indoor air handler in the garage, you can effectively cool or heat the space based on your requirements.
