Ductless Mini-Split Air Conditioning (and Heating) Systems

LEARNING CENTER
for Air Conditioning / Cooling
Ductless Mini-Split AC and Heating

These mini-split systems provide heating and cooling. They are a great equipment choice for home additions, or selective area heating and cooling, such as one floor or wing of a home. The advantages of a mini-split system over other types of cooling / heating equipment are:

  1. It can provide heating and cooling in homes that do not have air ducts.
  2. It provides independent temperature control for that area.
  3. It allows for the addition of air conditioning and heating in homes without ductwork, and with the least amount of disruption to the interior space.

Mini-split systems are made up of two primary parts, the outside part called a "condenser" (for cooling-only models) or “heat pump” (for heating and cooling models), and the inside part that mounts on an outside wall called an "air handler”. Some units have secondary back-up electric heat which gives them greater heating capabilities. The home temperature is set and changed by convenient remote control(s). (Note: These heat pumps will not operate in heating mode when outdoor temperature is below 29 F degrees.)

Mini-split systems are available to operate with one, two or three indoor air handlers, depending on the model. Each air handler is referred to as a "zone".

The systems here come with condenser or heat pump, air handler(s), and remote control(s). Select a system by size (heating and cooling capacity, rated in "BTUs"). The heat pump and air handler are connected together with copper pipes called a “line set” sold separately (see our "Accessories" tab on product page for line sets).
