I want cooler supply air in the bedroom than in the living room. Is this possible?

Many people prefer a lower temperature in the bedroom for better sleeping comfort, while the living room and other living areas can have a higher temperature. This often leads to questions about whether the ventilation system can be used for room-specific temperature control.

Yes, it is technically possible to achieve cooler supply air in the bedroom than in the living room by installing a cooling coil on the supply air ducts. However, this is often a costly solution. In most cases, it is more cost-effective to invest in other measures, such as external solar shading, improved window shading, or reducing heat gains in the room. Cooling via the ventilation system should generally be considered a supplement to such measures, rather than a primary solution for room cooling.
