Had 2 air con units installed. Relieved to be able to have a home that can be used year round and can have air con without external condenser. The condenser was installed in a hall cupboard which is far enough away from the other rooms to not be able to hear it churning away. The actual air con units were Panasonic and work as you’d expect. Quiet enough to be able to sleep with it running and controlled through tv Panasonic all (also wired in bedroom and hand held controller in living room). Yes it’s expensive but my home was unbearable in summer so I consider it an investment. The installers knew what they were doing despite being a tricky install with the amount of room they had to install the condenser. Overall I’m happy with the install and results.
