Ductless Mini Split AC
The “split” in ductless mini-split systems refers to the fact that there’s a separate outdoor unit and indoor units, which differ from packaged systems that have the equipment inside the air handler. The outdoor unit contains the compressor and condenser, while the indoor unit houses the evaporator coil (or heat pump in heat pump-only models) and blower. A refrigerant line, power cable, and condensate drain line connect the two units.
Many people consider a ductless system when they want to add heating or cooling to rooms such as sunrooms, garages, home additions, attics, and other rooms that don’t have ductwork. These spaces can be expensive to heat or cool using a standard furnace Mini Split AC and air conditioner, so a ductless system is often the best solution.
Another reason for considering a ductless system is that it’s less invasive than running ductwork to these hard-to-reach spaces. A ductless system can be installed without disturbing the existing walls, although some people dislike the look of an air handler hanging on the wall or the hole that needs to be drilled through the wall to run the conduit for the refrigerant and power lines.
Ductless mini-splits are also quieter than traditional window units, especially in the case of high efficiency models that include inverter technology to adjust the compressor speed and energy consumption. This reduces cycling on and off, which is a common cause of excessive noise.
If you’re interested in installing a ductless system, you should have it done by a professional for the best results and to ensure that the system is properly sized and positioned. Poor installation can result in poor air flow, higher energy use, and even damage to the system.
Most people think of wall-mounted mini-splits when they think of a ductless system, but these units are available in other configurations as well. Some rest on the floor, while others are concealed in ceiling cassettes. These are often the choice for areas that are hard to reach, such as attics and crawl spaces.
Regardless of how they’re mounted, all models offer advanced features that make them more than just energy efficient. These can include a powerful inverter, smart operation modes, smartphone app control, built-in air quality sensors, auto clean function, and self-diagnosis functionality.
Some brands, such as Gree, are known for focusing on advanced technologies that improve system performance and in-home comfort. Their G10 inverter, for example, is a highly advanced system that offers energy-saving inverter technology, intuitive sensing of indoor temperature, infrared remote control functionality, and more.
