The cost to install a 4-zone mini split typically ranges from $6,000 to $18,000.
Cost Breakdown:
For Della's mini splits, a single indoor unit uses an average of 3.7 to 10.2 amps. For a 4-zone system, the total amps would range from 14.8 to 40.8 amps, assuming all four indoor units operate simultaneously.
Benefits of Low Amps:
A mini split AC 4-zone system connects one outdoor condenser to four indoor air handlers through refrigerant lines, electrical wiring, and drain lines. Each indoor unit has its own thermostat, allowing independent temperature control for each zone. The outdoor unit adjusts compressor speed using inverter technology to match the combined heating or cooling demand of all four zones, ensuring efficient and precise performance.
A mini split system can support anywhere from 2 to 8 zones, depending on the capacity of the outdoor unit. Larger systems with higher BTU ratings are designed to handle more indoor heads, while smaller units are typically limited to 2 or 3-zones. The number of supported zones is determined by the system's design and refrigerant line connections available on the outdoor unit.
Maintaining a 4-zone mini split includes:
For a 4-zone mini split system using these models:
Each unit consumes between 830W and 1,140W during cooling and 770W to 1,090W during heating.
A 4-zone system operating all units simultaneously would use a total of 3,320W to 4,560W for cooling and 3,080W to 4,360W for heating.
