Air conditioning that heats your home this winter
The LG and Haier units we fit don't just cool. Switch to heat mode and the same wall unit warms the room quickly — then keeps you cool next summer.
One unit, all year
Warm in winter, cool in summer — no separate heater needed for that room.
Efficient warmth
Works like an air-to-air heat pump, typically using less electricity than plug-in heaters.
Fast to warm up
Heats the room in minutes, ideal for rooms you only use some of the time.
Your questions answered
Can air conditioning heat my home in winter?
Yes. The LG and Haier wall units we fit are reversible, so the same unit that cools in summer can blow warm air in winter. You switch to heat mode on the remote.
Is it cheaper than electric heaters?
Usually, yes. A reversible system works like an air-to-air heat pump: it moves heat in from outside rather than making it all from electricity, so it typically uses less power than a plug-in fan, panel or oil heater for the same warmth. Your actual cost depends on your tariff, the room and how you use it.
Does it work when it's freezing outside?
Modern systems keep heating in cold weather, though output drops as it gets colder. On frosty days the outdoor unit will pause briefly now and then to defrost itself — that's normal.
Will it replace my boiler?
For most homes it works best alongside your central heating — warming the rooms you use most, like a bedroom, home office or extension, without heating the whole house. It doesn't provide hot water.
Which rooms suit it best?
Rooms that are hard to heat or used at odd times: extensions, conservatories, loft rooms, garden offices and bedrooms.
How much does it cost to install?
Our installs start from £1,950 fully fitted, VAT included, for a single room. See our price guide for bigger rooms and multi-room systems.
