A ductless heat pump or air conditioner usually consists of a wall-mounted indoor unit combined with an outdoor compressor. It is most often used in a situation where a window air conditioning unit or baseboard heating would be considered, as a new addition to a house. But unlike window units, ductless units only require a very small hole to be drilled in the wall, making them less vulnerable to air leakage and safety issues. In addition, they are less visible and audible.
Ductless systems are more expensive than central air at the time of installation. However, due to their energy efficiency, they allow you to save money in the long run. Because ductless systems allow you the option of zoning, you have more control over how much energy is spent cooling each room. This can significantly reduce your utility bill over time compared to central air conditioning units.
Central air systems send coolant to a bulky central air handler which then blows cool air into the house through a ductwork. Ductless systems pump coolant to compact indoor units within individual rooms. Each split air conditioning unit works as a miniature air handler, supplying cool air to its own area only when needed. The main advantages of mini-splits are their small size and flexibility for zoning and cooling individual rooms.
Many models can have up to four indoor air handling units (for four zones or rooms) connected to one outdoor unit. The number depends on the amount of cooling required for the building or each zone. This can be affected by how well the building is insulated and sealed to air. Each of the zones will have its own thermostat, so you only need to condition that space when it is occupied, saving energy and money.
Compared to ducted central air systems, a ductless system can be incredibly energy efficient. However, because ducted AC systems are not zoned, they can suffer up to 25% energy loss. Apart from this, ductless air conditioners do not require special treatment, which allows you to save contractor and maintenance costs compared to ducted air conditioners. For many homeowners, mini-split systems provide adequate cooling and serve as an economical alternative to traditional air conditioning installations.
Other types of ductless systems include wall mounted multisplit, PTAC, portable air conditioners, window units or cassette type air conditioners. However, with a ductless system, the main parts of the unit are placed on the outside of the house and air comes out the side of the outdoor unit, rather than the top. Ducted air conditioning systems present the biggest problem in this regard, with the ductwork being an important source of pollutants. The absence of ducts means that ductless air conditioners can be installed in much less time than ducted air conditioners.
Ductless air conditioners and ductless heat pumps can be installed so that an indoor unit corresponds to an outdoor compressor. 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. This is because energy companies could use leftover energy by using less air conditioning for other, more pressing energy demands. Because of the increased efficiency offered by ductless systems, many utilities are now offering rebates and financial incentives to homeowners and businesses to install ductless air conditioners.
With Ductless, it's not just about controlling air temperature, it's about controlling air quality. It's good to know that a ductless heating system can improve the air quality of your home to ensure a healthy life. .
