Sleep in the perfect temperature all year round. Whisper-quiet Bosch units — cool in summer, warm in winter. 0% VAT on all domestic installations.
A bedroom is probably the single best place in your home to install air conditioning. Sleeping in a room that's too hot is one of the most common causes of poor sleep quality in the UK — and with summers getting hotter every year, the problem is only getting worse.
We only install bedroom air conditioning units that are whisper-quiet — designed specifically not to disturb sleep. At around 19–25dB on the lowest setting, you'll barely notice it's on. Most of our bedroom customers tell us their sleep improved immediately after installation.
All our bedroom units are heat pumps — so they heat as efficiently as they cool. In winter, they're one of the most energy-efficient ways to warm a bedroom, producing 3–4 units of heat per unit of electricity consumed.
Getting the temperature right in your bedroom isn't just about comfort — it has a direct impact on how well you sleep and how you feel the next day.
Sleep experts recommend a bedroom temperature of around 16–18°C for optimal rest. During UK summers, bedrooms routinely reach 24–28°C overnight — the point at which sleep quality degrades significantly, REM sleep is reduced, and you wake up feeling unrested. A bedroom AC unit maintains the exact temperature you set, automatically, through the whole night.
A cool bedroom promotes deeper sleep cycles and more restorative REM sleep. Most people report noticeably better sleep quality within the first night of running bedroom AC.
Set your bedroom to the ideal temperature before you go to bed — the unit reaches it quickly and holds it automatically. No waking up to adjust. No overheating at 3am.
As a heat pump, your bedroom unit heats in winter as efficiently as it cools in summer — replacing or supplementing radiators at a fraction of the running cost of electric heating.
AC filters the air as it circulates — capturing dust, pollen and allergens. For hay fever sufferers, sleeping with the window closed and the AC on is transformative during spring and summer.
The most common concern people have about bedroom air conditioning is noise. It's a valid one — but with a modern wall mounted Bosch unit, it's not a problem. At around 19–25dB on the lowest setting, these units are quieter than a whispered conversation.
To put that in context: a normal bedroom with windows closed typically sits around 30dB of ambient noise. Our units run below that. Many customers find the gentle white noise of the unit actually helps them sleep rather than hinders it.
We would never install a unit in a bedroom that we wouldn't be comfortable sleeping next to ourselves. That's why we only use wall mounted Bosch units — not ceiling cassettes, not portable units, not older technology that runs louder.
For bedrooms, the answer is almost always a wall mounted unit — but here's an overview of what's available.
The only unit we recommend for bedrooms. Mounted high on the wall, runs at ~20dB, and can be controlled from a remote or app. Heats and cools year-round. Fixed price from £1,049 installed including survey.

Installing AC in multiple bedrooms at the same time saves money — one outdoor unit serves multiple indoor heads. Often the most cost-effective option for families wanting to cool more than one bedroom. Ask about multi-room pricing on your survey.
For rooms where wall space above head height is limited — sloped ceilings, attic conversions, or rooms with large windows — a low wall or floor-mounted unit is the alternative to the standard wall mounted position. Same quiet operation, different height.
Installing in multiple bedrooms at once?
Multi-room installations are significantly more cost-effective than separate jobs. If you're thinking about more than one bedroom — or a bedroom and a living room — ask our surveyor to quote the whole house in one visit. Most customers find it's far more affordable than they expected.
Bedroom installations demand the quietest, most reliable units available — which is why we use Worcester Bosch air conditioning systems exclusively. At ~20dB on low, Bosch units are among the quietest in the market. They're also A+++ energy rated — so running them overnight doesn't add significantly to your electricity bill. And every unit we install comes with a 5-year guarantee on parts and labour, so if anything goes wrong in the first five years, we fix it at no cost to you.
We visit, measure the bedroom, check where to mount the unit and run the pipe to the outdoor unit, and give you a fixed price on the day. Most bedroom surveys take 20–30 minutes.
We calculate the right Bosch unit for your room — size and ceiling height matter. An oversized unit short-cycles and wastes energy; an undersized one struggles. We get it right every time.
Most bedroom installs complete in half a day. We protect your walls and floor throughout, drill a neat core hole for the pipework, and tidy up completely before leaving.
We walk you through the controls, set the unit to your preferred sleep temperature, and issue your 5-year Bosch guarantee. That night, you sleep better. It really is that straightforward.
"Kirk fitted 3 AC units in our upstairs bedroom and done a fantastic job. They protected my walls and floors, cleaned up afterwards and left perfectly. I would highly recommend THS and their crew. Thanks again for the brilliant job!"
"Air conditioning — it's a no brainer! It's a lot less expensive than you think & with Kirk fitting it no redecoration is necessary. Definitely get yours ASAP as it's only going to get hotter — trust Kirk to do an excellent job."
"I had THS air con install me a good Bosch unit at the start of the summer. I am really pleased with their work and my house is a nice comfortable temperature. Great job all round."
