  • Installation of Heating and Air Conditioning System

    10Verified Review

    Occasionally you deal with a company who restore your faith in human nature. Sub Cool is one of these. From our initial consultation with Alex, to the planning with Suzy (patiently answering my hundreds of questions) and then to installation team with Finn and Ryan (who were super professional, polite, clean and tidy and efficient) everything was excellent. Thrilled with the results. Highly competitive and overall, brilliant from start to finish. Well done Jacob and your whole team. A pleasure to deal with and couldn’t recommend Sub Cool highly enough.

    A complex situation, the Sub Cool Team were totally professional both at Head Office and onsite, delivering a great result. The installation team were courteous, well organised and worked extremely hard, each day leaving the site clean and tidy. Huge recommendation.

    Always said I would come back to Sub Cool FM if I needed air conditioning and have done - am guessing that says it all - you dont go back to a company if you are unhappy with their work and in this case Sub Cool excelled themselves - Good prices, great products expertly installed - who could ask for more

    Managed to get to me and then fit in for installation really quickly. Had a slight run over, but managed the return to finish really well. Polite and friendly people, happy to explain the different options and what would be suitable for us and just got on and delivered. Really pleased.
