Air con units for bedrooms: which is the best option?

Brits are known for complaining about the weather, especially when the temperature surges, but most UK homes simply aren’t prepared to cope with the heat, making it extremely uncomfortable to withstand. 

The summer weather is often most unmanageable at night when it’s too hot to rest under a quilt and relax. The heat also prevents your body from producing melatonin, the hormone which drops your core body temperature to help regulate your natural sleep cycle. 

Even opening the windows may not help, as sometimes there’s not enough of a breeze outside to cool you down, and you instead welcome in a family of insects and get woken up by loud noises through the night. Many turn to fans to solve their restless nights but these devices will often just move the hot air around the room and cause too much noise to sleep through. A 2025 BOXT survey of 1,000 people found that:

1 in 5 people have avoided their bed altogether during hot weather. Sleeping on sofas, in spare rooms or in cooler spots downstairs instead. 

If you want a permanent and effective solution to these poor night sleeps, invest in an air conditioning unit and never look back.

Air conditioning types

Portable air conditioners are easy to transport and ideal for occasional use or renters but aren’t as effective at cooling as other types.

Central air conditioners involve installing a duct throughout the existing walls and an outdoor compressor. These units can efficiently cool your entire house, including your bedroom, but require a bigger upfront investment.

If you only want to cool down your bedroom, a split system may be the most suitable option. It entails a professional installing one unit inside the property and another component on the outside. These units are more expensive than portable systems but less than central air conditioners and operate efficiently.

Multi-split air conditioners have multiple indoor units for cooling down different rooms. You can adjust the settings to only cool down the room you’re using without unnecessarily cooling down the entire house. With BOXT, you can cool up to 3 rooms with air conditioning units. 

When getting the units installed, don’t fit them directly over where your head will lie, as this can cause scratchy throats and an uncomfortably cold atmosphere. Instead, install it on the wall on either side of the bed.
