Bedroom air conditioning in London
Quiet units chosen for sleep, 19 to 26 decibels on night mode, sized and sited so you forget they are there.
Bedroom air conditioning in London costs £1,600–£2,400 excluding VAT installed, and the specification is different from any other room: the unit is chosen for its night-mode sound level, the quietest we fit run at 19–26 dB(A), below a whisper, sited away from the bed head, and sized so it cruises rather than cycles. A London bedroom under a slate roof can hold 28°C at midnight in July; this is the room where air conditioning pays for itself first.
This is for you if
- You have not slept properly through a July heatwave in years
- A top-floor or loft bedroom that holds the day's heat until 2am
- A fan just moves warm air around and the portable unit is louder than the street
- Pregnancy, young children or a health condition makes hot nights genuinely unsafe
- You sleep with windows closed, traffic, sirens or security, so the room never purges
- Night shifts mean you sleep through the hottest hours of the day
What's included
- A quiet-specification unit, night-mode sound level quoted in writing before you buy
- Positioning that never blows directly across the bed
- Condenser sited away from your bedroom window, and your neighbour's
- Sleep-mode setup: temperature ramp, dimmed display, silenced beeps
- Vacuum test, commissioning and controls demonstration
- F-Gas certification and manufacturer warranty registration
The standard we work to
F-Gas certified installation; condenser siting checked against night-time noise to neighbouring bedrooms, the constraint that decides most bedroom installs.

Bedrooms: what people ask
How quiet is bedroom air conditioning?
The units we specify for bedrooms run at 19–26 dB(A) on their lowest night setting, quieter than a library, at the threshold of hearing for most people. For calibration: a quality portable unit runs at 44–55 dB(A) in the same room, which is why people abandon them. The indoor sound level on low fan is printed in every manufacturer's data book; we quote it in writing so you can hold us to it.
Read the full answerIs it healthy to sleep with air conditioning on?
Set sensibly, yes, sleep research consistently puts ideal bedroom temperature around 16–19°C, and above about 24°C sleep quality measurably degrades. The complaints people associate with air conditioning, dry throat, stiff neck, come from a unit blasting cold air directly at the bed, which is a positioning error, not a property of cooling. We mount the unit so airflow washes the room, not the pillow, and set a sleep curve that drifts the temperature up gently overnight.
Read the full answerHow much does it cost to run air conditioning overnight?
A 2.5kW bedroom unit draws roughly 0.5–0.8kW while actively cooling, and much less once the room is at temperature, over an eight-hour night it typically uses 2–4kWh, which is roughly 50p–£1 at current unit rates. A full heatwave month of every-night use lands in the £15–£30 range. Modern inverter units modulate down rather than switching on and off, which is what keeps the overnight numbers low.
Read the full answerCan the condenser go outside my neighbour's bedroom?
It shouldn't, and we won't put it there. A condenser at night runs at roughly 45–50 dB(A) a metre away; ten metres and a fence away it fades into background, but mounted on a party wall below someone's bedroom window it is a dispute waiting to happen, and councils can act on night-time noise complaints. Siting the condenser where it bothers nobody, including you, is a fixed part of our survey, and occasionally it is the honest reason we advise against an install.
