Are you looking for a better way to cool your home? Central equipment can be powerful, but for many, summer cooling bills can be frustrating. Additionally, a forced-air system typically imposes one temperature setting on all members of a household, a frustration if one person prefers ice-cold conditions and another doesn’t. Ductless equipment offers an alternative that may alleviate several home comfort issues.

How Does Ductless Air Conditioning Work?

Ductless equipment is similar to central equipment in that a heat pump circulates refrigerant between indoor and outdoor units to prompt a heat exchange process that adjusts indoor air temperatures. As air temperatures are changed, indoor air handlers distribute the conditioned air. The primary difference between the two types of split systems is that with ductless equipment, smaller air handlers are placed in various spaces to handle this job more locally. Conditioned air is no longer forced through an extensive circuit of ductwork. Rather, it is moved directly into the area to be cooled or heated.

Where Are Components of Ductless Heat Pumps Installed?

There are two major elements in ductless multi splits. The outdoor unit should be installed close to the home in a location that is conducive to the running of refrigerant and electrical lines to various zones within the home. Indoor units are mounted in designated zones. A small opening through the exterior wall is required for each air handler so that the connecting lines can be directed between indoor and outdoor units. Indoor units can be selected based on decorative needs and concerns. Wall, floor or ceiling units are available.

Some homeowners are concerned about the visibility of indoor units. Others worry about noise levels with the air handlers so close to living spaces. The units can be placed discreetly for minimal visibility, and the quiet operation ensures that normal activities can occur without interruption. The whisper-quiet performance of modern ductless heat pumps can be a dramatic improvement over the loud activity of a central system.

What Are the Benefits of Ductless Multi Splits?

In addition to quiet operation and low visibility, ductless equipment offers several practical benefits, including:

  • Personalized comfort levels – units in each space can be programmed independently of others for specific comfort needs. The individual who desires an ultra-cold environment during cooling season doesn’t need to make everyone else freeze. This also saves money by not requiring excessive cooling energy for all spaces.
  • Better air quality – central equipment forces the entire supply of conditioned air through a common area, exposing it to contaminants such as dust, pet dander and other allergens. Multi splits deliver conditioned air directly into the specific zones without that common source of contamination. Additionally, room units have their own high-efficiency filters to ensure that the air passing through is carefully cleaned before its recirculation.
  • Lower energy bills – up to 40 percent of your home’s heating and cooling costs can be attributed to energy loss through duct walls and leaks. Eliminating ducts from the configuration of your home comfort system can markedly improve your overall energy requirements for heating and cooling. Additionally, independent programming allows you to minimize comfort control activity in spaces that are used less frequently.

Is a Ductless System Right for Me?

Although there are many benefits possible in converting from central equipment to a ductless configuration, you may wonder about how this will work in your home. A load calculation for both heating and cooling is recommended to ensure that proper system sizing is used. Additionally, it’s important to evaluate the number of room units needed to achieve your home comfort goals. Consulting an HVAC expert is important to ensure that the right system configuration is selected based on your structural and personal needs.
