How a Ductless HVAC System Can Keep You Comfortable

Similar to other systems, a ductless or mini-split HVAC system uses an outdoor unit and one or more indoor air handlers. The refrigerant flows through a small conduit to the indoor units. As long as the space is relatively small or there are multiple indoor air handlers, ductwork isn’t needed. You won’t need to worry about maintaining your ducts or repairing leaks. You can also save energy and lower the utility bills of your home in Palm Beach Gardens, Florida. A ductless HVAC system can keep you and your family comfortable with zoning, a quiet design, energy efficiency and fewer indoor pollutants.


Most HVAC systems have one thermostat near the center of the home. A ductless HVAC system with zoning has two or more thermostats, and each controls its own indoor air handlers. This setup allows you to control the temperature in each area or zone independently. You won’t have to heat or cool unoccupied rooms, and your family members won’t have to argue about thermostat settings. Many programmable thermostats let you control multiple zones with your computer or phone.

A Quiet Design

Since ductless systems don’t have ductwork, you’ll never have to worry about rattling or whistling noises from loose or leaky ducts. The sound of moving air isn’t as noticeable, and the fans are quieter and smaller. You can place the outdoor unit far away from your home to minimize the noise.

Energy Efficiency

Ductless systems are energy-efficient because they don’t lose air because of leaks in ductwork. Ductless mini-splits have inverter-driven compressors. Depending on the system’s needs, it will either speed up or slow down. This saves energy and prevents the system from overworking.

Fewer Indoor Pollutants

Dust, dirt, pollen, pet dander and other contaminants can accumulate in ductwork over time. These can eventually spread throughout the rest of your home, leading to excessive dust on your furniture and floors, allergy or asthma symptoms, and other problems. If you have existing ductwork, the technician will block your air registers when you have a ductless system installed. This prevents pollutants from spreading. In addition, each indoor air handler has its own air filter to stop contaminants from traveling between zones.
