If you’re considering new AC for a room addition, renovation, or home without existing ductwork, a ductless air conditioner may be the right fit. These systems have a unique setup, cooling your space with multiple indoor units that connect to one outdoor unit. Learn about the basics of this system to see if it’s the best option for your space.
A ductless system’s components are small and can be mounted in wall, floor, or ceiling spaces. These indoor units have an evaporator coil, an air handler, and blower to cool air. The system can be configured with a variety of BTU ratings to accommodate different cooling needs. The unit sizing process is complex, and it’s important to have a professional assess your space to ensure the system is correctly sized. Under- or overestimating the capacity needed will result in wasted energy and higher utility bills.
Ductless mini-splits use less energy than traditional systems Mini Split AC to cool and heat homes, and they work at much lower noise levels. In fact, the indoor units of some models operate at a sound level similar to rustling leaves or a whisper, making them ideal for spaces that require low noise. This is a major advantage over the humming, banging, and whirring noises often associated with standard HVAC equipment.
Another way that a ductless system saves you money is with variable fan speed, which allows it to cool rooms at a high initial fan speed then reduce the airflow to maintain the desired temperature. This saves energy by ensuring that the air is only being conditioned when you need it. This feature is available on most models, and it can help to reduce your energy costs significantly.
A key point to consider when choosing a ductless system is whether you require cooling only or heating as well. Some single-zone systems provide cooling only; if you’d like to add heating capabilities, look for a model that specifies “Heat Pump.”
Choosing the right ductless system is a big decision, and it’s essential to find an experienced contractor to perform your installation. Because a ductless system uses pressurized, electrically charged materials, improper installation can cause inefficiency and safety issues over time. Only a licensed HVAC professional is qualified to install a ductless system safely and effectively.
