Both are excellent Korean brands. Samsung EHS achieves slightly higher SCOP ratings (up to 5.0 vs LG's 4.65) and offers AI Auto Comfort technology. LG counters with R32 eco-refrigerant and exceptional value for money. Samsung is premium positioning, LG is value-focused premium.
Samsung EHS Mono operates at 38dB, while LG Therma V runs at 35dB. This makes LG marginally quieter - about 3 decibels difference, which is barely noticeable. Both are whisper-quiet and suitable for residential areas.
LG systems typically cost £8,000-£13,000 installed, while Samsung ranges £10,000-£15,000. After up to £9,000 BUS grant, LG costs £500-£5,500 and Samsung £2,500-£7,500. LG offers better value, Samsung justifies premium with AI features and higher efficiency.
Samsung wins for smart home integration with SmartThings ecosystem compatibility. If you already use Samsung SmartThings, the EHS integrates seamlessly. LG ThinQ is excellent but has a smaller ecosystem. For standalone use, both apps are intuitive and feature-rich.
LG offers 5 years parts with 10-year compressor warranty. Samsung provides 5 years parts and labour with 7-year compressor coverage. LG's longer compressor warranty (the most expensive component) gives it an edge for long-term peace of mind.
We install both brands and can recommend the perfect system for your budget, property, and lifestyle.
