21Aircon installs, services and repairs home air conditioning with engineering accuracy from our Newbury HQ, 75 miles in every direction. Itemised quotes, 90-minute arrival windows, none of the jargon.
Air conditioning is a heat pump. In summer it moves warmth out of your rooms; in winter it runs in reverse and brings warmth in. One tidy unit on the wall, both jobs, all year, from your phone or the dial.
Set it to 21°C on the hottest day and it holds there: quiet, even, and dry. No portable units cluttering the room, no broken sleep.
The same unit heats as well as cools. Switch it to warm and a room is cosy within minutes, so it earns its keep in January, not just July.
A heat pump moves warmth rather than burning energy to make it. For every £1 of electricity, you get roughly £3 to £4 of heating or cooling back: about a third of the running cost of electric heaters.
