How do you install a ductless air conditioner?

Ductless air conditioner installation requires expert planning and precise setup. First, an indoor air handler is mounted on a wall inside the room, while a condenser unit is installed outside. The two units are connected by refrigerant and electrical lines that run through a small opening in the wall. Once connected, the system is charged, tested, and calibrated to ensure optimal comfort. Ductless systems are ideal for home additions, converted garages, or older homes without central ductwork. At Mainstream, we install ductless AC systems with minimal disruption and maximum efficiency—tailored to fit your space and your needs.
