I can highly recommend 2 Masters. I have just had 2 split systems installed with the removal of an existing split system and an old box style air conditioner. They respond quickly to emails, they show up on time and have provided great advice. The cost was very reasonable and the team who did the installation were lovely. They also plastered my wall as requested and cleaned up beautifully afterwards.
I am extremely happy with the service I have received from 2 Masters.
