Wall mounted air conditioning units are the most common type of AC units used in air conditioning. Generally they are made up of two units: one internal and one external in a building. However these can be fitted on to a Multi split system, VRV or VRF also (for larger units). Wall mounted units provide heating and cooling and they come in a vast range. We at ACL London can supply branded models from Daikin to Mitsubishi to Carrier and plenty of other makes.
Many new systems come with WIFI ready and can be controlled via internet even at a long distance or away from your place of work or residence. Why not inquire about our range today. Contact us for a free quotation or enter your details here and a member of our team will contact you.
