LG & Haier — the two we put on most quotes.
We test everything we fit, and these two keep winning. On most quotes we'll price them side by side so you can pick the one that suits your budget — both heat in winter as well as they cool in summer.
LG
The brand we fit most. Near-silent bedroom units, polished app control and the Artcool styling that disappears into a room. 10-year warranty on the units we register.
Why we chose LG →Best valueHaier
The world's biggest home-appliance maker. Flexis Plus and Pearl ranges give you Wi-Fi control, self-cleaning and near-silent running for £100–£250 less per room than the premium names.
Why we chose Haier →Also fitting Daikin, Mitsubishi Electric, Samsung and Panasonic — compare every brand we fit →
