Ducted Air Conditioning Systems: A Whole-Building Solution

Ducted Air Conditioning Systems are the perfect option if you are looking for a way to keep the temperature in your home constant while saving the space a split system unit would take up. With ducts spreading air equally to each room, every room can have the desired temperature. It is also commonly used in larger housing or commercial applications that require whole-building cooling or heating. A Ducted Air Conditioning System offers an efficient and streamlined solution for maintaining consistent comfort throughout the entire space.
Applications: Ducted air conditioning is ideal for individuals seeking to heat or cool an entire building with one system rather than install numerous individual units in each room. In larger spaces, these systems can use less energy and be more efficient, by creating comfort and saving on cost, with the use of centralized units. This system is ideal for households in need of a consistent temperature in several different rooms.
Maintenance Requirements: Regular maintenance is required to keep dust and dirt out of the ducts of a ducted air conditioning system.
