Air conditioning
Stay cool through the summer and warm through the winter with one quiet, efficient system. Installed by Lacey Heating across Hertfordshire and Essex.

How it works
One system, all year round
Modern air conditioning is a type of heat pump. It moves heat rather than making it, which is why it can cool a room in July and heat it in January while using far less energy than traditional electric heating.
Cooling
Takes heat out of the room and releases it outside, keeping your home comfortable on the hottest days.
Heating
Runs in reverse to draw warmth from the outside air, even in winter, and bring it indoors.
Cleaner, drier air
Built-in filters capture dust and allergens, while dehumidifying helps rooms feel fresher.
Quiet and discreet
Slim wall-mounted or ceiling units run quietly in the background, with simple app or remote control.
Where it fits
Ideal for the rooms that are hardest to keep comfortable
Bedrooms and loft conversions
Top-floor rooms overheat first in summer. Air conditioning keeps them cool enough to sleep.
Home offices and garden rooms
Comfortable working space all year, without running heating for the whole house.
Extensions and open-plan spaces
Large glazed areas can be hard to heat and cool. Air conditioning handles both.
Homes without radiators
A practical low-carbon heating option for flats and properties where a full heat pump and radiator system isn't suitable.
