The best air conditioning system for your home depends on the number of rooms you want to cool, your budget and the type of property you live in.

Split-System Air Conditioning

A split system uses one indoor unit connected to an outdoor unit. It is ideal for cooling a single bedroom, living room, home office or loft conversion.


Split systems are quiet, energy-efficient and provide reliable cooling. However, they require professional installation and suitable space for an outdoor unit.

Multi-Split Air Conditioning

A multi-split system connects several indoor units to one outdoor unit. It is a good choice for larger homes or households that want independent temperature control in multiple rooms.


Although it costs more to install than a single split system, it can provide a cleaner and more efficient solution than fitting several separate outdoor units.

Portable Air Conditioners

Portable units are usually the most affordable option and do not require permanent installation. They can be moved between rooms and are suitable for occasional use in smaller spaces or rented properties.


However, portable air conditioners are often noisier and less efficient than professionally installed systems. They also require an open window or vent for the exhaust hose.


Which Option Is Right for You?


  • One regularly used room: Choose a split system.
  • Several rooms or a larger home: Consider a multi-split system.
  • Limited budget or temporary cooling: A portable unit may be suitable.
  • Rental property: Check your tenancy agreement before installing a permanent system.
  • Listed building or flat: You may need permission from the freeholder, building manager or local planning authority.


Before choosing a system, arrange a professional assessment. An experienced air conditioning engineer can calculate the cooling requirement, recommend the correct unit size and identify the most suitable installation position for your property.
