    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.

  • Highly recommended air-conditioning installers

    10Verified Review

    Originally we wanted to install an air- conditioning unit in the bedroom, but because adding an additional unit in the living room wasn’t hugely expensive we decided on both floors. Installation was very quick, although the lead time was about 2 months due to demand. We only had a good and professional experience with Sub- Cool and we’d definitely recommend them- worth a wait!

  • Professionalism, expertise, and attention to detail were outstanding.

    10Verified Review

    Sub-Cool FM installed 4 internal wall-mounted units, and a loft unit supplying 3 additional rooms in my townhouse. I cannot thank Warren Hunt and Conner enough for their exceptional installation work of my air conditioning system. Their level of professionalism was impeccable throughout the entire process, leaving me with peace of mind that my house was in expert hands. From the moment they arrived, I was impressed by their immaculate tidiness and courteous manners. They exceeded my expectations on every level, and I would highly recommend them to anyone seeking top-notch installation of AC.

    10Verified Review

    We have been very pleased with the service we have received from Sub-Cool from start to finish and would definitely recommend them. From the survey, to ordering, and fitting everyone we dealt with has been professional, helpful and excellent communication. We are really pleased with the Mitsubishi premium Zen units and as described they can run very quietly, so it is perfect for our bedroom.
