A ductless mini-split system heats and cools a home without using ductwork. Instead of pushing air through vents, the system delivers conditioned air directly into individual rooms or zones.
Each system includes an outdoor unit and one or more indoor units. The outdoor unit houses the compressor, while the indoor units are mounted inside the home and distribute heated or cooled air.
Refrigerant lines and electrical connections link the indoor and outdoor units through a small wall opening. This setup allows the system to transfer heat efficiently while minimizing energy loss.
Because each indoor unit operates independently, homeowners can control temperatures in specific areas. This zoned design improves comfort and reduces energy waste.
