Is LG mini-split any good?
Yes — LG mini-splits are a solid mid-range option. Our installers rate the lineup 4.7/5 based on real Long Island installs. LG is manufactured by LG Electronics, which means shared parts and proven engineering. For most Long Island homes the bigger factor is installation quality — a properly sized, properly commissioned LG will outperform a poorly installed premium brand every time.

Expert Review: LG Mini Splits
LG has aggressively closed the gap with the Japanese leaders by leaning into what they do best: consumer electronics and smart home integration. The LG ThinQ app is the most polished mini-split app on the market — full Alexa and Google Home voice control, geofencing that pre-cools your house before you arrive home from work, and detailed energy reports that help Long Island homeowners track their summer cooling costs. The Dual Inverter compressor delivers SEER2 up to 30 on the LA Series, putting LG efficiency in the same tier as Mitsubishi and Daikin at typically 10–15% lower price. The Art Cool Mirror indoor unit looks like a wall-mounted flat-screen TV and is a genuine differentiator in modern Long Island living rooms. The LG Red cold-climate line handles -13°F. The main tradeoff is dealer network — there are fewer LG-certified installers on Long Island than Mitsubishi Diamond Contractors, so warranty service can take longer. As a Lennox/LG installer, Homets keeps full parts inventory in our Hicksville warehouse.
