FAQs

Q.

What is a Ceiling Concealed Ducted Unit AC?

A.
A Ceiling Concealed Ducted Unit AC features the indoor unit and ductwork hidden in a ceiling or plenum, leaving only the grilles visible for a clean interior look. It provides steady airflow without affecting the room design. This design principle is central to the LG Ceiling Concealed Ducted Unit system.
Q.

What is the main difference between low, mid, and high static ducted units?

A.
The main difference lies in each unit’s static pressure capability and ability to handle air resistance. • Low static ducted unit : Designed for short and simple duct runs with minimal resistance (e.g., hotel rooms). • Mid static ducted unit : The most common choice for standard installations with moderate ductwork (e.g., spacious homes, small retail spaces). • High static ducted unit : Suitable for applications with long, complex ductwork (e.g., large auditoriums, offices, factories).

Well suited for premium homes or small offices. • VRF system : Multiple indoor units, including concealed ducted units, connect to one high capacity outdoor unit. Suitable for large buildings or commercial spaces with zoned temperature control.
Q.

Why do people choose a concealed ducted unit system?
