Tetra installs two kinds of cooling systems.
Multi-zone mini split
A multi-zone mini split system includes an outdoor component and an indoor component, connected by a series of refrigeration lines. You can purchase up to 7 indoor units per outdoor unit for whole-home heating and cooling. Multi-zone units are ideal if you want the efficiency of heat pump technology but cannot install ductwork, or if you want highly-customizable heating and cooling throughout your home.
Single-Zone Mini Split
A single-zone mini split system also includes an outdoor component and an indoor component, connected by a series of refrigeration lines. These systems come with one indoor unit that will heat and cool one room or area in your home. Additional zones cannot be added to a single-zone unit. Single zone units are ideal for small homes, or hot/cold spots like sunrooms and upper-floor bedrooms.
