Ducts are used in heating, ventilation, and air conditioning to deliver and remove air. These needed airflow include, for example, supply air, return air, and exhaust air. Ducts also deliver, most commonly as part of the supply air, ventilation air. As such, air ducts are one method of ensuring acceptable indoor air quality as well as thermal comfort.
A duct system is often called Ductwork. It contains planning, laying out, sizing, optimizing, detailing and finding the pressure losses through a duct system is called duct design.
Two types of units cool an entire house: a central air conditioner or a heat pump. If you only need to cool a specific area, a window air conditioning unit could be your most energy-conserving choice. Regardless of what type you are considering, remember that models will vary in efficiency ratings and efficiency has a direct impact on operating costs, so optimizing efficiency should be a priority.
If you want to cool your entire house, you should consider which system to install - central air conditioning or a heat pump - when reviewing your home's heating needs. An air conditioner is actually a heat pump that can only cool. Remember: your heating decisions can affect your cooling options.
Duct Work for Central Air Conditioning
Duct work is generally needed to carry cool air throughout the house in a central air conditioning system. If you have a forced air heating system, you can usually use the same ducts for cooling. If you do not have duct work, you can look into installing it or consider air conditioning technologies that have been developed for homes without ducts.
