Ductless Mini-Split Heat Pump Systems | Heating and Air Conditioning

When you plan a home renovation or intend to build a new home, the design process will include the selection of heating and air conditioning. Selecting a ductless system can significantly save on the budget, and continue to save you money with the reduced cost of energy. Ductless mini-split heat pump systems have two main components: an outdoor compressor/condenser, and an indoor air-handling unit. A conduit houses the power cable, refrigerant tubing, suction tubing, a condensate drain, and links the outdoor and indoor components.

Some models have multiple air handling units that all connect to one outdoor unit. Each air handling unit is assigned to a different zone or room, which is controlled by its own dedicated thermostat.

A Ductless split system is a logical choice for room additions where extending or installing ductwork is not possible, and are ideal for energy efficient new homes that require only a small space conditioning system.

Ductless HVAC Explained Duct free split systems don’t require ductwork for the delivery of heated or cooled air. The ductless system uses separate indoor units in each area for air to be delivered directly to the chosen spaces and provide precise temperatures for each zone. The ductless system has the additional advantage of being almost noise free.

You have both an indoor and outdoor component with a split system for central heating and air conditioning. With ductless technology, there are multiple indoor components to each outdoor unit. This enables you to take advantage of efficient zone heating and cooling in more than one room. Many Carrier ductless systems are Energy Star qualified for even greater savings.

How Ductless HVAC Saves Money

With the labor involved, the installation of ducts in a new home or addition drives the cost up. Going ductless can significantly reduce your construction costs by eliminating the need for ductwork and its installation.

A home’s ducts can cause an energy loss of up to 30 percent when improperly sealed. Furthermore, duct air leaks can lead to significant problems in home comfort levels, elevated energy bills and promote the growth of mold, a serious health issue. Ductless HVAC equipment saves money by eliminating energy loss through ducts, as well as eliminating the cost of ductwork and installation. Zone heating and cooling allows for customized control of temperature without the entire home being heated or cooled to the same temperature. By maintaining occupied areas at a comfortable temperature, while using minimal heat or cooling in unoccupied areas, you save money in energy costs. Ductless systems are among the most energy efficient heating and air conditioning systems available. It is an investment that keeps on refunding your investment costs with energy savings.

Ductless models can have up to four indoor air-handling units – enough for four zones or rooms connected to one outdoor unit. The number required depends upon the amount of heating and air conditioning that is required for the building or each zone. As it is with any proper HVAC installation, how well the building is insulated and air sealed and other factors will be necessary considerations in determining the proper system for a home. Each of the zones will have its own dedicated thermostat, enabling you to condition occupied spaces only, or that you choose to. This will save energy and consequently money.

Ductless mini-split systems are easier to install than other types of space conditioning systems. For example, the hook-up between the outdoor and indoor units generally requires only a three-inch hole through a wall for the conduit. An additional advantage of the hookup is that it leaves no access for an intruder as a window unit AC can.

Furthermore, numerous manufacturers of the ductless heating and air conditioning system can provide a variety of lengths of connecting conduits, and, if necessary, enables the location of the outdoor unit as far as 50 feet from the indoor evaporator. This makes it possible to cool rooms on one side of a house, but locate the outdoor component in a more advantageous or inconspicuous location.

In comparison to other add-on systems, mini splits offer increased interior design flexibility. The indoor air handlers can be suspended from a ceiling, mounted flush into a drop ceiling, or hung on a wall. Floor-standing models are also available. Most indoor units are about seven inches deep and have sleek, high tech-looking cabinets. Remote control may also be available to make it easier to turn the system on and off when it’s positioned high on a wall or suspended from a ceiling.


The cost of installing mini splits may be higher than other heating and air conditioning systems, though the lower operating costs, potential rebates or other financial incentives that may be offered can help offset the initial expense.

Installation must be provided by a qualified and reputable HVAC technician to avoid the problems related to over – or under –sizing the system. This is true with all heating and air conditioning systems. The installer also has to determine the best location for its installation. Oversized or incorrectly located air handlers can result in short cycling, which wastes energy and won’t provide proper temperature or humidity control. An oversized system is more expensive to buy and to operate, while an undersized will run too often, resulting in an elevated energy bill and premature wear.

An additional advantage to a ductless system is the elimination of air being circulated throughout the home, keeping airborne pathogens and pollutants from being distributed throughout the home.
