Air Conditioning for Bedrooms

Bedrooms are the rooms people suffer in most on hot nights. A fan just moves warm air around; an air conditioning unit actually cools it. And because the units we fit also heat, a bedroom unit takes the chill off on cold nights too.

For a room you sleep in, the two things that matter most are quiet running and the right size. Get those right and you sleep comfortably all year.

The units we fit run quietly enough for a bedroom. The indoor unit has a fan that runs on low speeds once the room is at temperature, and the outdoor unit sits outside where its sound is muffled by the wall.

We won't quote decibel figures because they vary by unit and setting, but we will tell you honestly what to expect, and we fit units we're happy to put in a bedroom.

A typical bedroom takes a 2.5kW unit — the smallest size we fit. A very large bedroom or a room with a lot of glazing might step up to a 3.5kW, but most bedrooms are a 2.5kW. We confirm the size after a look at the room.

A unit that's too big for a bedroom cools it too fast without removing the humidity, leaving the air clammy. The right size cools gently and quietly, which is what you want when you're trying to sleep.

The indoor unit mounts high on the wall, usually on the wall opposite or to the side of the bed, so the cool air circulates across the room rather than blowing straight onto you. We'll talk you through the best position.

The outdoor unit goes outside — on the ground, a bracket or a flat roof — wherever suits. We plan the pipework to keep it neat.

Every unit comes with a remote, and many have WiFi and app control, so you can adjust the temperature from your phone without getting up. You can set a timer to cool the room before you go to bed, or turn it off after you've dropped off.

It's a small thing, but on a hot night it makes a real difference.
