A ductless heating and air conditioning system is one that does not use traditional ducts, but rather implements individual units for each room within a property where heating and cooling is desired. In simple terms, ductless air conditioning systems (also known as minisplit) connect individual room units with an outdoor compressor. The indoor unit contains refrigerant-cooled evaporator coils. The warm air in the room blows and is sucked in by the coils.
From there, the coolant transfers all indoor heat to the outdoor unit. The short answer? Ductless ACs (also called “minisplit AC”) work the same way a central air conditioner works without ducts. With filters in each indoor unit, ductless systems provide cleaner air in the rooms where they are installed. With Ductless, it's not just about controlling air temperature, it's about controlling air quality.
When circulation is contained within a confined space, there is no cross-contamination of air between rooms. In cooling mode, a ductless heat pump operates essentially the same way as an air conditioner. The inclusion of a reversing valve allows coolant to flow in either direction, providing both heating and cooling from a single ductless system. A ductless minisplit system works on the same principles as larger HVAC systems.
The outdoor unit sucks air through one or two ventilation grilles. Some units have air vents on the sides and back, so you may need to install it one or two feet from the outside wall of your home. The unit also has an air vent on the front. Some models may need to be mounted on a platform to allow adequate airflow, protect the unit from the elements, and prevent it from sinking and moving.
The unit sucks air into your home through a small, flexible tube. The indoor unit heats and cools the air and sends it into space. Ductless minisplit systems are remotely controlled. With a ductless HVAC system, cold or conditioned air is distributed directly to each room without ducts.
In central air conditioning, cold air moves through ducts that are distributed in each room through air ducts and ventilation grilles. Ductless air conditioners and ductless heat pumps can be installed so that an indoor unit corresponds to an outdoor compressor. If there is a malfunction in one system, the rest will continue to provide air conditioning to unaffected areas. Three big advantages of ductless AC are energy efficiency, less air leakage and less noise during operation.
For many homeowners, mini-split systems provide adequate cooling and serve as an economical alternative to traditional air conditioning installations. Before installing a new ductless air conditioner or changing the existing system, it is important to understand how they work. Let's take a deeper look at how ductless air conditioners work and how they cool your home without the use of ducts. Like a central air conditioning system, the ductless air conditioning system draws heat from the air inside the house, moves it through a duct, and expels the heat to the outside environment.
As a full-service HVAC company, JAMCO Heating & Air Conditioning offers ductless minisplit systems for homes in South Jersey and Southeastern Pennsylvania. On the other hand, central ACs channel the cold air into a system of air ducts that then distribute it throughout the house. Conventional central air conditioners employ a single air handler, blower, and evaporator coil, which is typically installed in a garage or equipment cabinet. Ductless air conditioners and heat pumps offer exceptional flexibility and can be modified to suit many applications.
The versatility of ductless systems makes them perfect for many applications, including room additions, glazed terraces, garages, and they are an ideal air conditioning option for older homes. .
