Air conditioning for better sleep
A hot bedroom is one of the most common, and most fixable, reasons for a bad night's sleep. We install air conditioning across Surrey and Dorset to help bring bedrooms down to a temperature that actually supports proper rest, not just something bearable enough to fall asleep in eventually.
Why heat wrecks sleep quality
A study tracking bedroom temperature in older adults found sleep efficiency dropped by 5-10% once nighttime temperatures rose from 25°C to 30°C. Separately, a much larger study analysing over 3.75 million nights of sleep data found that higher bedroom temperatures were consistently linked to reduced sleep efficiency, longer time to fall asleep, and more time spent awake during the night, across the general adult population, not just older people. Whatever your age, a hot bedroom is working against you, not just making you uncomfortable.

The temperature sleep experts actually recommend
NHS and Sleep Charity guidance both point to 16-18°C as the ideal bedroom temperature for quality sleep, several degrees below what most UK bedrooms sit at during a heatwave, especially upstairs rooms or those under a loft.

Why temperature is important beyond just comfort
Sleep is when the body repairs itself and consolidates recovery from physical activity, which is exactly why heat-disrupted sleep affects far more than how tired you feel the next day. For anyone training seriously, working physically demanding hours, or just trying to function properly, a consistently cool bedroom is one of the most direct improvements available.

FAQ’S
-
Modern inverter units are designed to run quietly, generally quieter than a fan on a low setting once the room reaches temperature. We can talk through specific noise ratings for bedroom installs.
-
Most sleep guidance points to 16-18°C as the ideal range. We can talk through practical settings once your system's installed.
-
It depends on the layout, sometimes a single unit works for an open-plan or adjoining space, but generally each bedroom needing reliable cooling will need its own unit or a multi-room system. We'll assess this properly at the quote stage.
