Question from Electriq 18000 btu air con unit .: Asked on 24/03/2026 Can I extend ducting to other areas of the room?

Answer from JimsonGuzman: Answered on 24/03/2026

Hi, The unit is designed with adjustable cold air outlets that can be directed to different areas within the same space. However, the hot exhaust must be vented externally using the supplied ducting, kept as short and straight as possible. The exhaust duct should not be extended beyond its intended length or split to serve other areas, as this will restrict airflow, reduce cooling performance, and may cause the unit to operate inefficiently or overheat.


Thank you.
