You may have heard that going ductless can save you a lot of money on your heating and cooling bills, but have you ever wondered what is it about those big white boxes that saves users money? Ductless systems have gained popularity in recent years amongst home owners and HVAC technicians alike because of their sleep energy-saving design.
Duct systems have a central heating and cooling unit that draws in air from an outside unit.
The outside air is either heated or cooled, and sent through ducts to get to its final destination – your living room, bedroom, or wherever. The duct systems seems to make sense by creating all the heated or cooled air in one location, but the transport of this air to its final destination can basically undo what was done to it. As warm air travels through the ducts, not only does it have potential to deposit dirt and allergens along the way, reducing indoor air quality, but it also cools down substantially. The whole system has to work harder than it needs to. With ductless systems, the desired air temperature is created right there, in the very same room. Ductless models also have what is called an inverter-driven compressor. Instead of turning off and on like the familiar air conditioners, these units can ramp up or down. In addition to saving energy this also ensures constant temperature in the room. Compressors that turn off and on are supposed to save energy, but the fact of the matter is, a lot of energy is wasted during compressor start-up.
