In this article, we will explore whether a ductless mini-split system can provide the quiet operation you desire, allowing you to rest undisturbed and wake up refreshed.
What is a ductless mini-split system?
A ductless mini-split system is a heating and cooling system that does not require ductwork to distribute air. It consists of an outdoor unit, which houses the compressor and condenser, and one or more indoor units, which are responsible for delivering conditioned air directly into the room. These systems are considered highly efficient and offer zoning capabilities, allowing for individual temperature control in different areas or rooms of a building.
How does it work?
Ductless mini-split systems work by using refrigerant to transfer heat between the indoor and outdoor units. The outdoor unit compresses and circulates the refrigerant, which absorbs heat from the indoor air and releases it outside. The refrigerant is then pumped to the indoor unit, where it absorbs heat from the outside air and distributes it into the room. This process can be reversed during the winter to provide heating.
Advantages of ductless mini-split systems
There are several advantages to using ductless mini-split systems. Firstly, they offer easy installation, as they do not require any ductwork. This makes them a suitable option for buildings where ductwork is not feasible or cost-effective.
