Why air conditioning
Comfortable all year, not just in a heatwave
Modern air conditioning is a reverse-cycle heat pump. It cools your rooms on hot days and heats them efficiently through the colder months, all from a sleek indoor unit and a remote or phone app.
Cool, quiet summers
Better sleep and a comfortable home office, even on the UK's hottest days.
Efficient winter heating
Heat-pump technology turns each unit of electricity into several units of heat.
Pairs with solar
Already have solar panels? Run your cooling from your own free daytime energy.
Smart control
Set schedules and adjust every room from your phone, wherever you are.
Cleaner air
Built-in filtration helps reduce dust and pollen and controls humidity.
Installed by our own team
No subcontractors. The same people trusted by Essex homeowners for electrical and renewables work.
