FAQ
LG ducted: common questions
How much does a LG ducted cost installed?

Get up to three local quotes for your actual job.
Which is the most energy efficient?
For the average climate zone, the LG UHN100M3SH N30 (10.5 kW) has the highest cooling rating here at 3 stars. Star ratings on the zoned label run to 10, and a star is worth more in a hot zone than a mild one. For cold-climate heating, the LG UMN100M2 N20 leads at 2 stars.
What size ducted system do I need?
Most three-bedroom homes land around 10 to 14 kW and four-bedroom homes 14 to 18 kW, but insulation, ceiling height and zoning change it. Our sizing guide explains how installers work it out.
